What is the price of aluminum beverage can? What is the difference between aluminum beverage can and tin can?

When it comes to packaging, people have given different connotations. In the past, people thought that packaging was the use of appliances to contain items, or the operation of wrapping and bundling items, which merely played a role of accommodating items and facilitating access. This understanding is obviously one-sided. Now people have given a broader meaning to packaging. From a systemic point of view, it links the purpose, requirements, constituent elements, functions, and practical operations of packaging to form a complete concept.

 

The use of aluminum packaging materials has a short history, but because aluminum has its own unique characteristics, it has gradually increased as a food packaging material. The amount of aluminum used in aluminum foils, tubes and containers in China accounts for 2% of aluminum production. The main properties of aluminum are light weight, non-toxic, tasteless, beautiful, good processing performance, and shiny surface. In addition, because a dense alumina film can be formed on the surface of aluminum, it can effectively isolate the contact between aluminum and oxygen, and prevent further oxidation of the aluminum surface. However, it is corrosive in acid and alkali salt media, so almost all aluminum containers are used after spraying. Its strength is lower than steel, and its production cost is higher than steel, which is about five times that of steel. Therefore, aluminum is mainly used for sales packaging. For example, aluminum cans are mainly used for packaging of aerated drinks with a certain internal pressure. A small amount is used for transportation packaging.

What is the difference between aluminum beverage can and tin can?

Iron cans and aluminum cans are currently widely used, each with its own advantages.Z、 However, the current market for tin cans is more popular and advantageous.

The cans are made of aluminum alloy, and the inner wall is coated with some organic coating to isolate the aluminum alloy from the beverage. During the processing, it is inevitable that the protective coating is not applied or is too thin, so that the aluminum alloy on the inner wall of the can comes into contact with the beverage. The aluminum element gradually dissolves in it, especially when the can is filled with acidic or alkaline beverages.

Canned beverages should not be used often and often, especially children with strong growth and poor elderly excretory function, it is better to drink less. Refining aluminum cans can cause pollution. Aluminum cans are passivated and cannot be dissolved by ordinary weak acids.

Aluminum cans are generally coated with a protective layer on the inner wall. Acid substances generally do not erode aluminum cans during the shelf life, but if the shelf life has passed, it may not be necessary. If it is stored for too long, an acidic substance reacts with aluminum to cause aluminum ions to enter the beverage in large quantities. Aluminum will accumulate too much in the body, which will cause Alzheimer’s disease.

TIN CAN is also called a seam tank. It consists of a can body, a can lid, and a can bottom. The materials used are mainly tin-plated sheet steel (tinplate and chrome-plated sheet steel).

TIN CAN is widely used in the canning industry as well as in other industries such as chemical industry and daily necessities. Their structures are the same, but they are different according to the requirements of use, or the structure is appropriately deformed, or a certain structure is added with appropriate accessories. For example, metal cans used for tea, biscuits, candy, solid beverages, and metal cans containing cooking oil, liquid beverages, and chemical products, are basically the same as ordinary three-piece cans.

TIN CAN has the following functions:

(1) Protection function The protection function of the package is the most basic and important function. It should protect the product from damage and loss. In the process of circulation of goods, the factors that cause harm to them are: environmental conditions, such as temperature, humidity, gas, radiation, microorganisms, insects, rodents, etc., all of which may damage packaging and harm the product; human factors, the goods are In the process of loading, unloading and storage, due to careless or improper operation, the goods are damaged due to shock, vibration and drop, or they are crushed due to too many layers. Therefore, according to the form, characteristics, transportation environment, sales environment, and other factors of different products, the most appropriate materials, reasonable design of packaging containers and technology should be given to the packaging to protect the function, protect the safety of the products, and use dangerous goods. Special packaging, pay attention to prevent its damage to the surrounding environment and people and living things.

(2) Convenient functions: Modern product packaging can bring a lot of convenience to people, which plays an important role in improving work efficiency and quality of life. The convenient functions of packaging should be reflected in the following aspects.

 

① Convenient production: For products produced in large quantities, packaging must meet the needs of production enterprises for mechanization, specialization, and automation, taking into account resource capacity and production costs, and improving labor productivity as much as possible.

② Convenient storage and transportation. For the quality and volume (size, shape, etc.) of each packaging container, consideration should be given to the convenient loading and unloading of various transportation tools and stacking; and the quality of manual loading and unloading should generally not exceed 40% of the weight of the worker. (Limited to about 20kg), etc .; At the same time, it is necessary to consider the storage, stacking methods, shelf display effects, indoor display and storage during consumption in the warehouse, store, and house during distribution.

③ Convenient to use: Suitable packaging should make consumers feel convenient when opening, using, keeping and storing. Such as cardboard boxes, cans, spray packaging, portable packaging, etc. sealed with tape, explain the precautions and use methods to consumers in simple and concise language or illustrations for easy use.

④ Convenient handling: It means that some packages have the function of reuse. For example, turnover boxes of various materials, glass bottles for beer and beverages, and packaging waste (paper packaging, wooden packaging, metal packaging, etc.) are recycled, which is convenient for environmental protection and conducive to saving resources.

(3) Sales function: Packaging is like a silent salesman. Good packaging can attract consumers ‘attention and stimulate consumers’ desire to buy. The sales function of packaging is achieved through packaging design. Excellent packaging design, with its exquisite shapes, reasonable structure, eye-catching trademarks, decent words and bright colors, etc., directly stimulates consumers’ desire to buy and leads to purchase behavior. Some packaging also has potential value, such as beautiful and suitable packaging containers, which can also be used to hold other items after the contents are used up. Specially shaped containers and beautifully printed decorations can not only increase the price of goods, but also promote the sale of goods. It can also be used as an art connoisseur collection.

three piece can manufacturing process?

A three-piece can is also called a seam can. It consists of a can body, a can lid, and a can bottom. The material used is mainly tin-plated sheet steel (tinplate and chrome-plated sheet steel).

Since the advent of canning in the early 19th century, three-piece cans have been used as the main packaging container in the food canning industry. The three-piece tinplate cans produced in the early days, whether it is blanking, molding, or the sealing of the can body, as well as the bottom and sealing, are performed manually.All seams are sealed by soldering, which has a very low production efficiency. . With the development of industry and technological progress, the welding technology has also been continuously improved: the advent of automatic can welding machines has eliminated the manual operation of the welding process; the invention of the flanging sealing machine and the use of liquid sealants have made it appear in the early 20th century The sealing (bottom) technology of the “double crimping” has gradually realized mechanization, and the production speed has continued to increase. However, since the advent of the three-piece tin can for more than 100 years, tin solder cans have always dominated.Since tin solder contains a large amount of heavy metal lead, it poses a serious threat to the food hygiene in the can, so the side seam bonding method and Welding of side seams (ie resistance welding). Now resistance welding has become the most important method for manufacturing three-piece cans of food, and soldering has been basically eliminated.

In addition to the widespread use of cans in the canning industry, three-piece cans are also widely used in other industries such as chemical industry and daily necessities. Their structures are the same, but they are different according to the requirements of use, or the structure is appropriately deformed, or a certain structure is added with appropriate accessories. For example, metal cans used for tea, biscuits, candy, solid beverages, and metal cans containing cooking oil, liquid beverages, and chemical products, are basically the same as ordinary three-piece cans.

Since China established its first cannery in 1906, the production of three-piece cans has been limited to the food canning industry. More than 20 years of reform and opening up, China’s canning industry has also developed rapidly. In addition to domestic manufacturers that can provide domestic automatic canning equipment, it has also introduced more than 100 advanced automatic canning production lines from abroad. There are hundreds of iron can manufacturing enterprises in China, and the production capacity has ranked among the top in the world. It can produce a variety of metal cans to meet the needs of the development of the national economy and the improvement of people’s living standards.

The process flow and characteristics of the three-piece can manufacturing process are as follows:

Cutting→ (scribing) → rolling → tack welding → internal and external coating→ drying → (cutting), (rolling), (neck),(Bulging), (Embossing) → Flanging →bottom seaming → Leak detection → (Full internal spray) → (Drying) → Stacking and packaging

The bracketed parts in the above steps can be configured according to the needs of the tank type.

Characteristics of resistance welding process: seam welding of the can body does not require brazing, which fundamentally eliminates the pollution of lead to the food in the solder and saves the solder; the strength of the weld is high and the seal of the weld is good; the weld overlap is small (0.25 -0.8mm), saving raw materials, narrow welding seam, especially after adding gas protection at the welding seam, the appearance is more beautiful and beautiful; the thickness of the welding seam is similar to the thickness of the tank body plate, about 1.3 to 1.5 times, which is convenient for flanging, necking, Sealing; high sealing quality, good air tightness of the can; fast production speed, up to 1000 cans / min.

Three-piece can production line equipment classification Three-piece can production line manufacturing equipment is divided into slitting equipment, expanding and welding equipment, coating equipment, dry equipment, rolling equipment, straddle cutting equipment, necking equipment, bulging, embossing equipment, flanging equipment, cap making equipment, can sealing equipment, leak detection equipment, full internal spray equipment, drying equipment, stacking equipment, packing equipment, etc.
