Oversupply Domestic Two-piece Aluminum Cans Hit a New Low

According to a research report released by China Securities Research and Development Department in May this year, the output of two-piece aluminum cans in my country will reach 38 billion cans in 2021. According to the annual growth rate of 8%, it is estimated that the annual output in 2022 will reach 41 billion. Can.

The report pointed out that due to severe overcapacity and an extremely fierce price war, the unit price of two aluminum cans has been declining in the past few years, and will drop to a record low in 2022.

The report believes that with the intensification of industry consolidation, it will help to improve the existing competition pattern in the metal packaging industry, and the price of two-piece cans can be expected to bottom out.

However, the process may seem a little long now. According to the “Securities Times” report, Baosteel Packaging recently stated on the interactive platform that the current metal packaging two-piece can industry is still in a situation of oversupply, fierce competition in the industry, and the unit price of products has not been fundamentally reversed, and steel, aluminum, etc. The large fluctuations in commodity prices have brought greater pressure to the company’s operations. The company has made a lot of improvement measures from the four aspects of the sales side, the purchasing side, the manufacturing side and the expense side to ensure the company’s operating performance.

Global Aluminum Aerosol Can Production Bucked the Trend and Increased to 5.5 Billion

Bonus points for functionality and sustainability, global aluminum aerosol can production bucked the trend and increased to 5.5 billion.

Economic and political issues did not adversely affect the 2016 performance of the International Association of Aluminum Aerosol Can Manufacturers (Aerobal) corporate members. According to a new report by the association, the global aluminum aerosol can industry achieved 3% growth in 2016, with production reaching 5.5 billion units.

Asia’s growth rate leads the world Asia’s fastest-growing market, with a growth rate of nearly 10%. This was followed by North and Central and South America, where sales increased by about 5% year-on-year, an above-average growth rate. In addition, even the saturated European market is stable.

Aerobal’s secretary-general, Gregor Spengler, said Asia’s per capita consumption of aluminium aerosol cans is well below the global average, so the region has considerable growth potential.

Personal care products account for about 80% of cans, with deodorants and fragrances being the two main driving sectors. In terms of product types and application areas, deodorants and fragrances are the two main driving application sectors for the growth of aluminum aerosol cans. They are still warmly welcomed around the world, opening up new growth potential. The two contributed more than 50% to the consumption of aluminum aerosol cans in 2016.

Other important products and applications in the cosmetic sector include hair sprays, hair styling mousses, and shaving creams. Overall, the personal care segment accounts for about 80% of total aerosol can production. About 10% of aluminium aerosol cans are used in industrial and household products, and 5% go into pharmaceuticals.

In terms of products and applications, Gregor sees growth in markets such as foaming body washes and dry shampoos, as well as broad application areas for sunscreen products.

Outstanding functionality will make aluminum aerosol cans gain in the field of pharmaceuticals. “In addition, there are obvious growth opportunities in the pharmaceutical field in the future.” Spengler believes that in the future, it will mainly rely on the outstanding functionality of aluminum aerosol cans – mainly reflected in the excellent product protection and maximum safety of aluminum over other materials. , to ensure market growth. Especially in the pharmaceutical industry, the excellent hygiene standards of aerosol cans and the accuracy of dosage are unmatched by other packaging solutions.

Sustainability benefits make aluminum aerosol cans impeccable. Sustainability and environmental characteristics will continue to play an important role in the packaging market, he said, and aluminium aerosol cans are particularly impeccable in this regard.

“Customers and consumers are increasingly recognizing that aluminum is a sustainable material that can be recycled indefinitely without any loss of quality. Among the many functional benefits of aluminum aerosol cans, this is one of the most significant, high resource utilization Let it make a valuable contribution to the future of the planet,” he added.

The ink is the result of a collaboration between the design team at Crown Beverage Can Europe and the Middle East and CTI. Since the ink changes with the temperature, consumers can see the relevant display information after drinking the cold contents.

According to Crown, when the cold contents are consumed, specially developed ink can change the graphics and text of the can, which is interesting.

China’s New National Standard Metal Container Cans Safety Standards Will Be Higher

Recently, on the official website of the National Standardization Administration of China, the new version of “General Technical Requirements for Canned Food Metal Containers” is soliciting comments. The new version puts forward new requirements for the appearance of metal cans and the integrity of the inner film coating.

Those with poor appearance are considered substandard products

For example, in terms of appearance, tin cans are required to meet the characteristics of beauty and no damage. In the production process, there are many situations such as large slump, jump seal, incomplete curling, sharp edge and quick mouth, etc., will be regarded as unqualified products.

Higher requirements for the integrity of the inner film coating of metal cans

Not only in terms of appearance, but also for metal inner film coating, there are many requirements. For example, by adding 2% sodium sulfate solution to the metal can, the integrity of the can coating film is tested. In addition, acid resistance, sulfur resistance and salt resistance tests are carried out. For the performance of the tank sealant, there are also strict standards. The tank is put into a glass container filled with water for testing to observe the tightness.

Overall, the new national standard “General Technical Requirements for Canned Food Metal Containers” puts forward more stringent requirements for metal canned food containers. Although the new national standard is a recommended standard, some large canned food manufacturers generally This implementation will be gradually regulated according to the new national standard. Therefore, it is certain that the safety of canned food will be improved in the future, and the common people will be more assured to eat.

Two-piece Can Ten-color Keyless Inking Printing System

With the landmark two-piece beverage can printing system CS MetalCan, KBA-MetalPrint GmbH, the market leader in printing and coating iron equipment and ovens, has won the MetPack 2017 Innovation Award Silver Award, while also breaking the field A situation dominated by companies such as Stolle and Unimaq for a long time. Together with the pin oven/belt oven, this system forms the two-piece can solution Can Solutions.

KBA Metal Printing is a subsidiary of Germany’s KBA Group, the world’s second largest supplier of offset presses, whose 200 years of deep roots and innovation in printing technology have led to the breakthrough two-piece can printing system CS MetalCan, which has The metal printing industry sets new standards.

As the first ten-color printing system in beverage can printing with a keyless inking unit and a state-of-the-art drive, CS MetalCan responds to the market’s demand for increasingly frequent job changeovers and more diverse products. The perfect interaction of the components optimizes print quality, productivity and safety.

Ten-color printing, keyless inking technology achieves the best print quality. The ten keyless inking units not only provide two-piece beverage can designers with complete, new chromatographic options, but the modular design also enables short-term changeovers.

The keyless inking unit from KBA, specially developed for the printing of two-piece beverage cans, consists of a temperature-controlled anilox transfer roller, an inker roller, and different transfer roller combinations for reliable key color inks coated.

The inking unit is modular and easy to replace. In addition, the inking unit is compatible with all installation positions and can therefore be removed and repositioned in the shortest possible time.

High automation greatly improves productivity, and the changeover time is less than 10 minutes. The main motor of CSMetalCan is specially designed to reach a maximum speed of 2500 cans/min. In particular, the keyless inking technology is an excellent assist at this extreme speed – due to the reduced thickness of the ink layer on the ink roller of the inking unit, the phenomenon of ink splattering is less likely to occur.

The system uses a unique drive concept. Each inking unit and blanket unit adopts a dedicated drive device to achieve independent drive. Digital driveshafts ensure 100% synchronisation of the inking units.

The plate changer, designed for two-piece beverage cans, is modular in design to accommodate quick plate changes. During the production process, the printing plate of the next job can be put into the plate loading channel at the same time. When a “change plate” command is given, the complete set or selected plates are automatically replaced. The old plate is first unloaded from the plate cylinder and then slid into the discharge channel to make way for the new plate to be installed. Whether it is a single plate or all plates, the entire plate change process takes about 1 minute.

When changing the plate, the blanket can be changed at the same time. The optional blanket changer is a fully automatic system. The pre-prepared blankets are placed in a convenient box and supplied to the blanket changer. When the “change blanket” command is given, the blanket currently in use is first moved into a separate discharge box, and then the new blanket is installed on the blanket cylinder, and the blanket replacement takes about 4 minutes.

In addition, CS MetalCan can prepare jobs for the next job during production, such as preparing printing plates and preparing inks on inking units that are not currently in use. The makeready process can occur in parallel with ongoing production, making job changes faster than ever – makeready time (changeover time) has dropped from 25 minutes to less than 10 minutes!

Safer The dramatic increase in automation, and the defined interactions between machine modules, also frees the operator from the hectic shuttle between the printing units. On the one hand, high automation creates a safety-oriented working environment for the operator; on the other hand, CS MetalCan also adopts a specially designed protection concept to eliminate all possible hazards to the operator in the working environment.

“Cold Printing” Green LEDs Are Cured and Dried, Reducing Energy Consumption by Up to 93%

Although PrintabLED, an Italian UV printing and coating LED curing system supplier, is an industry rookie that has been established for less than 6 years, it is the crystallization of more than 30 years of industry experience of the two partners. In 2011, Mr. Massimiliano Dal Pont, together with SERIGRAFIA 76, a large screen printing company in Europe, jointly established a company with the same name as the product for the launch of the PrintabLED® UV printing and coating LED curing and drying equipment project. The former is the major shareholder of Dal Pont Engineering Co., Ltd., which has a 20-year history in the design, R&D, and production of printing machinery suitable for various materials, while the latter has been rooted in the field of automotive screen printing for more than 35 years.

Product manager Patieck Montali summed up the advantages of PrintabLED to the author as follows.

Energy consumption is reduced by up to 87%~93% Because the power of the LED lamps used in the PrintabLED curing system is less than one-third of the traditional UV lamps, the energy consumption can be reduced by up to 87%~93%.

It is reported that the curing system has two options of narrow radiation spectrum lamps, one is a high-power Q lamp (16W), which is suitable for ultra-high-speed printing and curing, and is generally installed at the end of the production line. The other is a medium-power LP lamp, suitable for high-speed partial curing and drying, or low-speed complete drying, generally installed between printing units.

High power Q lamp

Medium power LP tube
Figure 2 Medium power LP tube

Cold Printing is attributed to the patented solution for extracting heat from the LED chip, such as the integration of a small cooling system, which makes the energy-to-temperature ratio the highest on the current market, it is said that “the difference in sheet temperature before and after curing and drying” only 0.5°C”. This is very beneficial for the printing of heat-sensitive materials, and completely eliminates the problem of overprinting caused by thermal expansion.

Environmentally friendly Another advantage of the narrow radiation spectrum lamps is that the CO2 emissions are significantly reduced, the ozone emissions are zero, the harmful ultraviolet UVC radiation is completely eliminated, and the noise of the working environment is reduced.

Modular construction makes installation easy Whether it’s a new installation or a retrofit of an old one, the modular PrintabLED system can be custom designed to integrate into a specific piece of equipment or application.

Canned Luncheon Meat: Sealed Taste Memories

The source of canned lunch meat is in the United Kingdom and the United States. Luncheon meat is the translation of the English “Luncheon meats”. In the United Kingdom and the United States, it refers to cold cuts of meat used in cold cuts such as cocktail parties and cold dinner parties, such as various sausages, hams, meat rolls, bacon, barbecue, aspic, etc. . At the end of the 19th century, in response to market needs, especially for long-distance transportation and long-term preservation, canned fresh beef appeared in the United Kingdom, and canned spiced ham appeared in the United States. Because it is mostly used for cold cuts, it is also called “luncheon meat” by some businesses. However, at that time, these cans were mostly in large packages, 6 pounds (2.72 kg) per can, mainly sold by wholesalers to various retail food stores for refrigeration, and the stores then sliced ​​and sold them to customers according to specific needs.

During the Great Depression of the 1930s, Hormel Spiced Ham, a cheap shredded pork shoulder and processed with salt, water, sugar and sodium nitrite, had the advantage of being a 12-ounce can ( 336g) small package, suitable for one-time household use, and does not require refrigeration. Later in 1937, a little ham was added and the name was changed to SPAM (Shoulder of pork and Ham).

What really made lunch meat popular was World War II. This well-preserved, inexpensive canned food is procured in bulk and distributed to the military, who often eat fried and grilled luncheon meat three times a day, and many people are fed up with them. Despite this, it spread to all parts of the Eurasian continent with the US military during World War II, and was also transported to the United Kingdom, the Soviet Union and other places as military supplies to aid the Allied forces. The U.S. military also introduced luncheon meat to Hawaii and the Philippines, and the locals are still popular with luncheon meat rice balls. Luncheon meat produced in the United States was also introduced to Shanghai and other places before and after World War II. At that time, Kuomintang soldiers were also fortunate to eat this foreign food.

It was very late in China to produce its own luncheon meat. In 1957, the Shanghai Meilin Canning Factory (then named Shanghai Yimin No. 2 Food Factory) produced the first can of luncheon meat. Speaking of which, “Meilin” is one of the earliest canning factories in China. In the spring of 1929, Shi Yongxi, Dai Xingshui and several other young Chinese western chefs raised hundreds of yuan to buy a soil stove, a steamer and some simple tools, and put them on Lanwei Ai Road (now Zhaozhou Lude in Luwan District) in the French Concession. A Shikumen hut at No. 13, Lane 78, Xiangli, is trial-producing spicy soy sauce, jam, tomato sauce and other western food accompaniments. In July 1930, Shanghai Meilin Canned Food Factory was formally established – the Meilin brand has a foreign flavor, which is transliterated from the Roman word “MALING” – and launched the first bottle of canned tomato sauce produced by the Chinese, mainly for supplying The most common western restaurant in Shanghai. Subsequently, bottled foods such as spicy sauce, jam, and green beans were successively developed, which were cheap and high-quality, breaking the situation that imported foreign goods dominated the world.

Three years later, a number of western food vendors in Shanghai joined the investment and jointly established Shanghai Meilin Canned Food Factory Co., Ltd., purchased a large number of foreign machines in Hongqiao, hired Lithuanian experts as engineers, produced products according to international standards, and later replaced imports. The large market share of canned food made it the most famous canned food brand in Shanghai and even the whole country at that time, and it was also exported to the United States, Southeast Asia and other places. Meilin has also developed canned food such as braised pork, braised beef, braised chicken, braised bamboo shoots, four fresh roasted bran, spiced grass sparrow, anchovies and other canned foods for domestic tastes. Canned cucumbers have been exported to the Soviet Union, Poland, Czech Republic and other socialist countries. In 1954, canned oranges in sugar water were also exported to the British Isles.

The popularity of luncheon meat in China is taught by the Czechs. In 1957, Czech food expert Schanil went to Shanghai Merlin Canning Factory to instruct the production of the first can of luncheon meat. After more than 20 years, it was mainly exported to Eastern Europe, Hong Kong and Macao and other places as well as to supply military supplies. Local people had to rely on the relationship approval to buy. It was not until the 1980s that canned luncheon meat, a food originating from Europe, entered China’s urban and rural areas on a large scale, and it became one of the most famous and attractive canned foods in the following two decades.

Development and Application Exploration of Easy-tear Lid Heat-sealing Adhesive Technology

With the continuous development of the social economy, consumers have put forward higher requirements for the convenience, safety and aesthetics of food packaging, which makes the application of new packaging including easy-tear covers increasingly widespread.

Development and Application Exploration of Easy-tear Lid Heat-sealing Adhesive Technology

As a new type of cover film packaging, the easy-tear cover has the advantages of safety and hygiene, beautiful appearance and easy opening. It is mainly used in food packaging and has now become a standard cover type of international food metal cans. In addition, it is notable for its environmental friendliness – the wafers left by the punching process of the base cover can be recycled and reused; the food-grade composite film on the cover is smaller in thickness and mass, saving natural resources, even if it is opened by consumers Discarded after use will also degrade naturally without causing environmental pollution.

As far as easy-tear lid heat-sealing materials are concerned, as a solution to overcome the problem of “easy rust in the incision” caused by the easy-tear lid sealing film, domestic easy-tear lid heat-sealing materials have achieved great results in product development and application exploration. Significant progress has been made, and it is expected to help industry users improve economic benefits through import substitution.

Easy-tear cover processing technology

Easy-tear cover is a new composite technology that is bonded by aluminum foil and tinplate or coated metal substrate. It has the characteristics of high sealing and certain pressure resistance. Its processing technology includes: using tinplate or aluminum as the basic material, after punching, stretching, and rounding, shaping treatment, so as to achieve the purpose of being safe and not hurting hands after opening; covered with metal composite film or ultra-high temperature resistant The sterilized composite plastic film is then processed by handle making and embossing for a beautiful appearance and easy opening.

Types and application characteristics of easy-tear lid sealing film

Most of the heat-sealed easy-tear covers use the aluminum-plastic lamination process, and the materials used to achieve the bonding properties are modified polyolefins or polyvinyl acetates. After heating, the film layer melts and is bonded to the substrate.

Polyolefin-based film Polyolefin-based film has excellent water resistance due to its low polarity, no hydrophilic group, and is often used in the easy-tear-cover packaging of yogurt, lunch boxes, hot pot takeaway and other products. But it is also because of the low polarity that modified polyolefins are usually pre-coated with film glue on the aluminum foil, and the film can be well adhered to the aluminum foil substrate through the glue.

Polyvinyl acetate film Polyvinyl acetate film has a high content of ester bonds in the molecular structure, and its water resistance is weakened, so it is often used in the easy-tear cover packaging of dried fruits, tea leaves and nuts.

After long-term research and development, the application of coated iron or coated aluminum easy-tear cover products has gradually matured. However, since the metal substrate at the incision is directly exposed after the lamination product is formed, it is easy to corrode, which affects the food safety and the adaptability of the product. Therefore, how to effectively avoid or reduce the corrosion of the incision has become the current lamination and easy-tear cover industry. a major problem.

Types and application characteristics of easy-tear cover heat sealant (roller hot melt adhesive)

At present, in addition to film-coated easy-tear cover products, there are also some easy-tear covers that use a roll-coating hot-melt adhesive process, and the film thickness is relatively thin (about 10 μm). Compared with the lamination products obtained by extrusion coating, cast film, blown film and other production methods, the use of roll coating hot melt adhesive technology can not only improve production efficiency, save material costs, but also obtain higher product quality stability. More importantly, due to the strong adhesion between the coating and the substrate, the degree of notch corrosion is reduced to a certain extent.

The hot melt adhesives involved in the roll coating process of the easy-tear cover are currently concentrated on materials such as modified saturated polyester, ethylene acrylate copolymer, and modified polyacrylate. , the market scale is gradually expanding, and the application prospect is broad.

Saturated polyester resins Saturated polyester resins are prepared from different polyacids and polyols. By controlling the structure of the monomers used, two different structures, Linear and Branched, can be obtained (Figure 4). If a linear structure of polyols and polyacids is used, the synthesized resin has a linear structure and is very flexible. If a polybasic acid and polyol containing a benzene ring are used, the synthesized resin contains a benzene ring structure. The rigidity of the benzene ring can give the resin hardness, and the stable structure of the benzene ring can give the resin chemical resistance. Because the main chain of the polyester resin contains more ester bonds, the molecular chain has good flexibility, and the terminal or side chain contains polar carboxyl or hydroxyl groups (that is, the acid value or hydroxyl value we often say), they can either As a heat sealant itself, it can also be cured into a film by cross-linking with isocyanate, amino resin and other resins to improve the chemical resistance of the adhesive layer.

Formula developers can screen resins according to product requirements, select appropriate curing agents for product design, and related easy-tear lid product applications include takeaway lunch boxes, dried fruit cans, milk powder cans, etc.

Ethylene acrylate copolymer Ethylene acrylate copolymer is a polymer based on acrylate monomers, by introducing ethylene or vinyl monomers for copolymerization, and using oxygen or peroxide as initiators through free radical polymerization. Its structure is shown in Figure 5(A). The introduction of vinyl monomers endows polymers with adhesiveness and film-forming properties; acrylate monomers provide polymers with good substrate adhesion properties. As the content of vinyl monomers increases, the properties of such polymers will gradually approach those of vinyl polymers—chemical resistance increases, but their stability in solution may decrease to a large extent, so it is necessary to adjust the two The proportion of class monomers to achieve the desired product performance. At present, this kind of polymer has oily and water-based systems, and the oil-based system is widely used. Because vinyl monomer is difficult to disperse in aqueous solution, its application is limited to a certain extent. At present, the vinyl content of water-based ethylene acrylate copolymer on the market is less than 20%. Milk cans, etc.

Modified polyacrylate polymer, modified polyacrylate polymer refers to the polymer obtained by repolymerization or graft modification of polyacrylate through chemical reaction between macromolecules after the completion of polymerization. Modified polyacrylate polymers include polyurethane-modified polyacrylates, polyester-modified polyacrylates, silicone-modified polyacrylates, etc., all of which have the advantages of both modified polymers and polyacrylates. Polyacrylate has the flexibility of the polymer chain, its glass transition temperature (Tg) is low, and the temperature varies with the number of carbon atoms in the ester group and its branching, and it will form a glossy paint film after coating. , strong adhesion, not easy to peel off, can be used in adhesives in different occasions, including easy-tear cover products.

Formula developers can screen resins according to product requirements and select suitable curing agents for product design. The application of related easy-tear lid products covers takeaway lunch boxes, dried fruit cans, milk powder cans, etc.

The localization of easy-tear cover hot melt adhesive will help users reduce costs

At present, most suppliers of easy-tear cover materials are foreign manufacturers, with high prices and relatively limited supply. Therefore, realizing the localization of easy-tear cover materials is a direction for material people.

The Ultimate Recycling of Tin Cans

In the past few months, thyssenkrupp Rasselstein, a subsidiary of Germany’s thyssenkrupp Steel Europe and one of the three major steel production giants in Europe, and Swiss packaging supplier Hoffmann Neopac have successively released news, as two As a result of a pilot project jointly carried out by the authors, the tin-plated iron used in the Recyclan (recycled cans) is all recycled iron from household packaging, and the packaging can also be recycled an unlimited number of times. This not only pushes the recycling and regeneration of iron cans to the extreme, saving valuable basic resources and energy consumption such as iron ore, coking coal, limestone, etc., but also marks the iron cans with the organic food green packaging credit label, making the strict requirements and sales Customers of organic products get their wish.

According to thyssenkrupp Rasselstein’s official website, the company has a history of more than 250 years, producing cold-rolled tin-plated or chrome-plated steel sheets with a thickness of 0.100~0.499mm. The annual output of packaging steel is about 1.5 million tons, and its applications include food cans, beverages Cans, aerosol cans, paint cans, and various metal cap products like crown caps and screw caps.

Tin Plated Iron Packaging: One of the Most Environmentally Friendly Sustainable Packaging

For many years, tin-plated iron has been regarded as an excellent packaging material for organic food, coffee, tea, candy, dry or paste cosmetics and other care products due to its good content protection properties. At the same time, one of the biggest advantages of tin-plated iron packaging is that it can be recycled indefinitely without loss of quality such as strength, making it more common than other packaging materials.
Can Recycling: Closed Material Cycle Globally, packaging iron is typically made from natural raw materials such as iron ore, coking coal, limestone, and recycled scrap iron. One of the properties of steel is that it can be melted repeatedly and processed into new steel products. Another feature is that iron is magnetic, and once collected for recycling, magnets can be used to separate steel packaging from other waste very easily and quickly during picking.

Therefore, it can be said that if iron cans are well classified and processed today and enter the recycling system, they may become parts of bicycles tomorrow, and may also become part of automobiles the day after tomorrow. Even tin-plated iron produced decades ago, if it has been in a closed material cycle, will still appear on newly produced steel products. According to WV Stahl calculations, 84% of the previously produced steel is still being recycled.
In addition to being used as a component of the aforementioned automobiles and rails, the iron cans can also be made into iron cans after regeneration. The concept of Recycan is said to have been conceived by Hoffmann Neopac in response to a customer request, through cooperation with supplier partner thyssenkrupp Rasselstein, and finally proposed a “recycling of tin-plated iron waste from household packaging, such as metal cans, crown caps, claw type screw caps to make new food jars” idea. Mark Aegler, CEO of Hoffmann Neopac, said that in Europe, North America and other developed markets, tin-plated iron cans are synonymous with “environmentally sustainable” due to their ability to regenerate in a well-established recirculation stream.

Domestic and foreign situation of tin-plated iron packaging recovery rate Data from the British Metal Packaging Manufacturers Association (MPMA) shows that metal packaging is the most recycled packaging material in Europe, with a recycling rate of 82.5% for steel packaging. In Germany, the recycling rate of tinned iron packaging has exceeded this level for ten consecutive years, and even reached 90.4% in 2018 (data from GVM).

In my country, household tin-plated iron packaging has been facing the dilemma of “rejection by scavengers and low recovery rate” for a long time. Only in 2019, the two milk powder giants, Mead Johnson and Nestlé, successively launched milk powder can recycling programs, aiming to help the circular economy and eliminate the potential safety hazards caused by the recycling of waste cans by informal channels. The driving effect of tin-plated iron packaging recycling remains to be seen.

RecyCan: From household waste tin-plated iron packaging to new tin cans for new purposes, pushing the recycling of tin-plated iron packaging to the extreme

Generally speaking, all tinplate cans contain some amount of recycled iron. Made from 100% recycled tin-plated iron, the RecyCan product line takes tin-plated can recycling to the extreme, a way to maximize the recycling of consumer steel packaging without compromising the appearance and contents of the packaging. A full-cycle way to protect performance, while packaging can be recycled almost infinitely, the label effect of green packaging goes without saying.

Seven steps of the full cycle method for tinned iron packaging In a nutshell, RecyCan’s idea is to remelt steel packaging waste from households into molten steel, which is then processed through a complex system to produce new food cans tin plate, and finally into new food cans.

Take a milk powder can as an example, its original role was to protect infant formula. After the milk powder is used up, the milk powder can is collected along with other household recycling items. At the picking station, it can be easily separated from plastics and other metals with magnets, entering the recycling system along with other discarded household steel packaging such as lids, crown caps, etc. Then through the processes of chopping, pressing, cleaning, detinning, burning, melting, pouring, etc., it becomes a well-formed thick steel plate. It is then hot-rolled into coils, cold-rolled, tinned, cut into sheets, printed, and finally made into new consumer packaging cans, such as high-end organic coffee, so the new function allows the packaging to open a new life journey.

The first step is to collect waste cans, screw caps and crown caps from the household.

The second step is to separate the tinned iron packaging from the aluminum and plastic packaging with a magnet and chop.

The third step is to detin the scrap iron and then press it into squares.

The fourth step is to melt the iron block into molten steel, and then pour it into a thick iron plate.

The fifth step is to hot-roll, cold-roll, tin-plate, and cut the thick plate to become a tin-plated sheet for packaging.

The sixth step is to print on recycled tinplate, which is then made into a new tin can.

The seventh step is the retail and consumption of the canned product.

The above seven steps allow tin-plated iron packaging to be fully reused for packaging production, thus forming a closed journey of consumer packaging.
