7 Ways to Reduce Packaging Costs-tinplate Boxes

The main function of packaging is to protect products from being damaged by external forces during transportation; each product is transported using packaging. Whether you have just established a new company and are looking for lower-cost packaging, or are a mature packaging box manufacturer, this article is to help you reduce the cost of custom packaging, especially how to reduce the cost of custom tinplate boxes.

1. Check the packaging dimensions of your custom tin boxes to make sure they fit the products they protect and transport.

The principle of protection applies to all products. If you are using a packaging box that requires a lot of filler (more than around), you may increase the cost of packaging. Since most tin box packaging manufacturers have more than 100 kinds of library size molds, you can find the tinplate box packaging of your own size.

2. Choose the correct tinplate box design and style.

A good rule of thumb for tinplate packaging is “the simpler, the cheaper.” If you customize the tinplate box packaging box so that it opens at the smallest size and the largest size is the deepest, this allows the smallest amount of tinplate used to produce the box and the fewer manufacturing processes; therefore, “the simpler, the cheaper.” There are many tinplate box styles available. Standard RSC-style shipping containers are the most common, but if you have a rectangular product, a custom-made tinplate box with a rectangular top cover and gong bottom structure may be more effective and can be made with less tinplate.

Make sure you use a rated (not overkill) tinplate box to transport the weight you want to pack.

There are many grades of tinplate boxes. Tinplate grades ranging from non-test grade to over food grade are common.

3. Industry knowledge is priceless; knowing when the price of tinplate rises or falls can make you better negotiate with tinplate box suppliers.

Use the Internet, social media, magazines and other resources to obtain industry news and tinplate pricing online. When the price of tinplate drops, asking for a better price will save you a lot of custom tinplate box costs. If the price of tinplate increases, your tinplate box manufacturer should notify you and allow you to pre-order before the effective price increase date.

4. Replace tinplate box manufacturers to get some competitive prices.

The Internet is very suitable for purchasing retail products, but not for industrial products. You still need to find a good local tinplate manufacturer and ask them to quote. You want to be a customer whose tinplate box salesperson knows that just mentioning a price increase will buy the price. Business relationships do exist, but friendly competitiveness can greatly help reduce packaging costs. Coupled with the introduction of a second supplier, you can provide a backup supplier and take a fresh look at your process. In many cases, the cost is saved by changing the packaging method or the size of the box.

5. Change tinplate box packaging to reduce transportation cost.

We know that this is not entirely about saving the cost of the shipping box, but if you can reduce the weight of the box by changing the packaging method, so as to reduce the single transportation cost. In addition, changing the box size to allow more products to be placed on the pallet can increase the total amount of products transported, and the entire vehicle can even reduce the shipping cost of each product.

6. A large number of customized tinplate boxes can reduce the unit price.

Most tinplate box manufacturers calculate the price in square meters per roll of tinplate. The printing of tinplate boxes requires a minimum order quantity, the more the quantity printed, the lower the unit price. The price reduction may reach 3-10%. If you want to order between 3000 and 10000 boxes, you will find that the price of 3000 can be 3-15% higher than the price of 10000 boxes.

7. On-time inventory and a blanket purchase order during the period of use.

Many packaging distributors will store your customized packaging boxes for you according to a blanket purchase order agreement, and distribute them when you need them. This will allow you to buy more quantities (usually at a lower cost) and receive boxes as needed. This should sell at a lower price and keep your cash flow and inventory constant, because you should only pay for the goods when you receive them.

Why Can Tinplate Cans Be So Popular in All Major Industries?

With the advancement of science and technology and the improvement of people’s living standards, people’s vision of pursuing new things is getting higher and higher. The outer packaging of items is no longer a way of thinking that you can pack things before. People are more inclined to the quality and beauty of the outer packaging of items. In order to adapt to the changes of the times, the design of the tin can is also very novel and unique, which can meet the requirements of each business.

Although the price of tinplate can packaging products is a bit more expensive than other packaging products (such as plastic products, wood products, paper products, glass products, etc.), they are cost-effective, high-quality, and elegant in appearance.

As iron can packaging containers to withstand various mechanical processing during the production process, they must adapt to the requirements of factory mechanization and automated production, while at the same time having high efficiency, stable quality, low cost and meeting the requirements of modern production management. The iron cans that have undergone mechanical processing will not only have strong rigidity, but also have enhanced sealing properties. Because iron itself is opaque, iron cans are the most reliable for storing food.

There are various printing styles and shapes of tin cans. It plays an important role in promoting product sales.

Gift industry: attract customers with unique and charming appearance and exquisite patterns, especially when giving gifts, gift packaging is very important, a simple detail can reflect one’s taste, so choosing customized gift packaging will let you The products are more attractive.

Tea industry: The storage requirements of tea are very high. It must be dry and not exposed to strong light. In short, it should be stored as little as possible in contact with the air, otherwise it will easily deteriorate due to moisture absorption. The reason why many tea manufacturers use tinplate cans for tea is because tins made of tinplate are not only rigid, but also tightly sealed, which can retain the fragrance of tea for a long time and prevent the tea from contacting moisture and oxygen in the air.

Snack food industry: Tinplate snack cans come in many shapes, such as square, round, special-shaped (heart-shaped, lip-shaped, spherical, car-shaped, oval, etc.). Usually, special-shaped snack packaging cans are the most attractive. Alien shapes are relatively rare in life, and they are rare and expensive. Therefore, the use of special-shaped iron cans for snack packaging can greatly increase sales.

What Are Tin Cans Made Of?

Tinplate cans (tin cans) are considered to be one of the most popular packaging materials in the world. These small tin cans are easy to manufacture and inexpensive, and can be made in any color, shape and design. Although the names may imply different, these cans are not actually made of tin. So, what is the tin can made of?

Tin cans-what are they made of?

Although empty cans are often referred to as “tin cans,” few modern tin cans are produced entirely from tin cans. The main reason people call these empty cans “cans” can be traced back to the late 20th century. At that time, the tank was made of tin-plated steel with the purpose of combining the strength and endurance of steel with the corrosion resistance of tin.

Nowadays, generally speaking, empty tin cans are made of any thin metal. The range is from aluminum to steel or iron. Although this is not always the case, these small tin cans are usually tinned. Since the 1960s, aluminum has so far become the first choice for the production of small tin cans. The reason behind it is that it is cheaper and easier to form. As a result, the manufacturing process has become cheaper and less time-consuming than before. As we all know, aluminum has the same corrosion resistance, so it is an ideal substitute.

The reason why an empty can cannot be made entirely of tin is, in fact, tin is a very rare material. Although it is considered a “common metal” and not a “precious metal” like gold or platinum, its availability is still less than you might think. In fact, tin may also be one of the least “common” metals in there. Indeed, the number of tin mines in the world is limited. Scientists even predict that in the future, we may completely run out of tin.

For the reasons mentioned above, it would be very expensive and difficult to make anything with pure tin. This is especially true for everyday items (such as packaging materials). As of today (2018), the price of tin is US$20.61 per kilogram, while the price of aluminum is only US$2.1 per kilogram. (2018) As you can imagine, this major price difference leads to the fact that manufacturers would rather use different metals to produce tin cans. Most of the empty cans produced today are made of aluminum or other cheap alloys.

Traditional tinned cans

The only product produced by pure tin is tin foil. This material is usually used for scientific experience, but can also be used to wrap other objects, such as chocolate bars. Because tin can be squashed in a very thin sheet, it allows us to create a large amount of “plating” with only a small amount of tin. In addition to making tin foil, this coating is often used in traditional containers. It is estimated that one pound of pure tin can produce up to 12.08 square meters of tin foil or tin plating. (2018) For this reason, tin has become very popular in electroplating and is often used in pure metal cans.

In addition to the fact that tin can be easily leveled, there is another reason to use it as a plating material. Tin does not interact with oxygen-therefore, it does not rust or discolor, and it is highly resistant to corrosion.

Today, we use most of the tin in the world to produce tinplate cans. These empty cans are mainly made of tinned steel or iron. Therefore, all can only be composed of 1% or 2% tin. This forms a coating on the metal to protect it from the elements. Because of its protective function, the coating can be used for a large number of commercial items, such as tin cans and other packaging.

Tin cans are mainly used for the storage of canned food, cosmetics, medicines and candles in the form of candle jars. Ordinary metals usually react with the acids present in these substances, and then they begin to corrode. Once this happens, the can will release molecules that may contaminate the contents of the package, and it will destroy the can itself. In the past, this especially caused problems with lead packaging. As we all know, these jars leach harmful toxins out of them. However, due to the acid resistance of tinned metal cans, food, cosmetics and medicines can be stored for a longer period of time, which is completely safe. The only disadvantage of traditional tinned cans is that they are much heavier than aluminum cans.

Modern tin can

Generally speaking, tinned cans are considered the “traditional” way of producing cans. In today’s world, the vast majority of small tin cans sold are made of aluminum or different types of processed metals. Any material is suitable as long as it is easy to form and resistant to rust and corrosion. Both traditional cans and modern cans are very suitable for canning purposes and can also be recycled. Therefore, manufacturers can strip the tinplate layer and reuse the iron or steel for scrap metal.

What is the Commercial Value of Special-shaped Tinplate Cans?

At present, products in tinplate cans are very popular in the market, such as milk powder, beverages, gifts, snacks, tea, coffee, candles, candies and so on. Why are these products keen on tin packaging? What commercial value can tin packaging bring to your store?

First of all, we need to know that the shapes of tinplate cans are all sorts of strange, round cans, spherical cans, square cans, special-shaped cans, and special-shaped cans have lip-shaped, heart-shaped, car-shaped, belly-shaped, oval, animal-shaped and so on. Many consumers may think that common cans, such as round cans and square cans, are too ordinary and not attractive.

Therefore, they are often attracted by some new things, and the special-shaped cans are especially in line with the consumer’s aesthetic cans. The more special things, the more they want to find out.

In the cosmetics industry, heart-shaped, lip-shaped, and flower-shaped cosmetic boxes will arouse the hearts of girls. Can the kawaii appearance, exquisite patterns, and bright colors look bad in the eyes of consumers? Now this society is chasing fashion beauty. As long as the shape and structure can keep up with the trend of the times, you are not afraid that your products will not be sold!

In the tea industry, tea cans are generally of high quality, and it feels more worthy to send to relatives and friends. Tea culture is a traditional culture that has been passed down in our ancient times. It has a long history and even foreigners love to drink Chinese tea. There are many types of tea, and there are also many tea packaging cans. The ones we often come into contact with may be square, round, and rare pot-bellied cans, or other special-shaped cans. To be honest, the pot-bellied pot is a practical and exquisite tea pot I have seen. It is not cumbersome at all, looks comfortable, and feels great to the touch. Its appearance can be embossed with patterns, especially retro and not fashionable. You can check it out online to see if what I said is true or false.

In the food industry, the food industry does not require much of the shape of iron cans, but the quality requirements such as the degree of sealing and hardness of the iron cans are somewhat high. The iron can itself is very rigid and extensible, and can be made into iron cans of various shapes. There is no doubt about the tightness of the iron cans. The crimping machine and manual edge grinding make the iron cans have no gaps.

All in all, for different products, use different tin can designs to show your sales philosophy and let your products enjoy the hearts of the people.

How Can Tinplate Can Be Designed to Attract Customers

The type, size and sealing method of metal cans are restricted by can making equipment. At present, many metal containers, especially cans for canned food and materials, have been standardized in size, structure and form. The standardization and standardization of metal containers have also promoted the standardization and standardization of related manufacturing facilities, thereby making the molding and manufacturing of containers relatively simple and easy. Therefore, the structural design of the metal cans is essentially just selecting the cans type, material and decorating design on the outer surface of the cans according to the user’s requirements.

The determination of the can’s structure of all the cans must take into account factors such as packaging requirements and manufacturing costs.

(1)Factors affecting cost, round cans compared with other special-shaped cans, round cans are not only relatively easy to manufacture, but also use less materials. In the capacity phase。

Under the same conditions, a container with a regular hexahedron uses 40% more material than a round cans, but from the perspective of the round lid’s cutting rate, the utilization rate during optimal discharge can only reach about 80%. Therefore, when designing metal cans, from the perspective of saving materials and reducing costs, round cans should be used as much as possible. The special-shaped cans has a unique shape and its cost is more than twice that of the cylindrical cans. It is only used when necessary.

In addition, the production efficiency of the two-piece can production line is higher than that of the three-piece can, but the investment in equipment is much larger than that of the three-piece can. These factors must be taken into account when determining the economic structure of the metal can.

(2)When selecting the can shape, the packaging requirements of the contents should be met,the metal cans should be determined according to the characteristics of the contents and the packaging requirements.

Structure, shape, opening method, sealing form, bottom and cover and side seam structure, etc. Common opening methods are cut-open, roll-open, pull-open, etc., and the sealing forms are air-tight and non-air-tight. Food cans and beverage cans generally require good sealing, and the sealing method can choose a double seaming structure; the opening method: generally the former using a cut-open type, the latter adopts a pull-open type, and the lunch meat is to ensure that the shape of the meat is complete when the can is open. , Mostly take the side unwrapped square can as the packaging container. An important feature of non-food cans is that they can be opened and resealed multiple times.Among them, art cans mainly used for daily necessities and cosmetic packaging, attaching great importance to artistic styling and decoration design; The metal cans mainly used for paints, oils and small packages of some chemical products, pay attention to the performance of the use rather than pay attention to decoration, which requires convenient transportation and a certain strength. The universal can used for tea and candy packaging can be sealed with a lid. The joint between the can body and the can lid does not require a double seaming. In addition, whether to install locking rings on the lid and bottom of the metal cans, whether rolling ring ribs are needed around the can body depends on the specific requirements of the production process and transportation environment. When the standard roll seal structure is selected, the size design and calculation of the roll seal structure can no longer be performed.

In short, when determining the structure of metal cans, factors such as the characteristics of packaging, packaging requirements and cost must be considered.

How Are Tin Cans Made

Tinplate can, as the name suggests, is a packaging can made of tinplate. Tinplate is the tin on the surface of iron to protect it. Compared with other materials, cans are more widely used, such as tea cans, biscuit cans, gift cans, wine cans and so on. In addition to the diversity of printing on the surface of the can, and the good gloss, it is more beautiful and beautiful. The reason why people like to use tin can packaging is that the compatibility strength of tin can is good and it is suitable for preservation.

Tinned tinplate is the material of tinplate. Because of its excellent metal toughness, tinplate can be easily made into different shapes, which makes the metal packaging container full of variety. It can not only increase the sales volume of packaging products, but also have artistic and recyclable green packaging characteristics. In the future development space, it is still open and incomparable. The following Makou iron can factory Bo new can for you to explain the manufacturing process of iron cans, I believe you can broaden your horizons!

1.Before making tins, we need to select materials. Tinplate types can be divided into: bright iron, silver iron and smooth iron. Smooth iron is widely used in can making. The above several kinds of iron materials have their own characteristics and can produce different effects. Therefore, different materials should be selected according to the characteristics of the products in the can making production.

2.After determining the can making material, it is necessary to determine the shape and making process of the can. At present, the main shapes of can are square, rectangle, circle and so on. The shape of foreign cans tends to be special-shaped, such as chezai can, heart-shaped can, plum shaped can, lip shaped can and so on. In the production process. Embossing, embossing, hollowing out and printing are the conventional production processes, but the effect of each process is obviously different, so it needs to be determined according to the customer and product positioning factors.

3.Printing oil selection. The iron material after printing needs oil treatment. This process can directly affect the visual and tactile effects of consumers on the cans. Different oils bring different visual and tactile feelings. The purpose of oiling is to attract consumers and improve product sales. At present, the more common oil is light oil (transparent oil), followed by dumb oil. There are explosion oil, pearl oil, wrinkle oil, rubber oil, etc.

With the continuous improvement of can making technology and the continuous updating of equipment, the automation level of tin can packaging production is higher and higher, the process is more sophisticated and the finished products are more exquisite. And the cost will get lower and lower. Can packaging is bound to become the packaging products chosen by manufacturers in various fields!
