We found that in people’s daily lives, the food cans that people often come into contact with are made of tinplate materials. With the development of science and technology, packaging materials have become more and more abundant. However, in the past 100 years, most of the food cans have been packaged with tinplate materials. Why food cans use ma。

In fact, tinplate is an iron plate with tinned surface. We know that food cans are always in a humid environment. In a humid environment, iron is very easy to react with oxygen in the air and rust. Once rust is damaged, some bacteria in the air will enter. In the can, the food spoils quickly.

In order to protect iron from corrosion, people thought of a wonderful way to make iron wear “clothes”. What kind of material should be chosen for iron “clothes”? It is considered that since the can is used to hold food, this material must be non-toxic, and the coating formed after it is plated on the iron surface should be firm and dense, and air must not be allowed to come into contact with the iron. Picking and picking tin is the most suitable. It is not only non-toxic, but it can form a layer of “armor” to protect itself in the air, put it on the iron, and the air should be allowed to progress to the inside of the metal. Therefore, tin is plated on the surface of the iron, which can effectively prevent the spoilage of the food in the can.

Tinplate has many advantages such as good sealing, preservation, light-proofing, firmness and unique metal decoration charm; strong oxidation resistance; high strength of tinplate packaging containers, good formability, and strong product compatibility.

Tin has stable chemical properties and is not easily corroded. People often plate tin on the outside of the iron sheet to prevent the iron sheet from rusting. This kind of tin “clothing” is known as “tinplate”. If you pay attention to protection, tinplate can be used for more than ten years without rust. However, once the tin “clothing” is accidentally broken, the iron sheet is quickly corroded (electrochemical corrosion), and before long, the entire tinplate is covered with red-brown iron rust spots. Therefore, when using tinplate, care should be taken not to damage the tin layer, nor to expose it to moisture or heat.

How tin cans are manufactured? We will introduce it to you in this article.

Three-piece cans and empty cans manufacturing process and characteristics。

1.The manufacturing process and characteristics of resistance welding and laser welding of empty cans are as follows:

Cutting board→(Scribe)→Knead the iron into a circle→Position welding→Inside and outside welding seam repainting and drying→(Slitting), (Rolling), (Neck), (Bulging), (Pressing) Flower)→Flanging and one bottom→leak detection→(full internal spray)→(drying)→stack one package

The bracketed part in the above process can be configured according to the needs of the tank type.

Characteristics of resistance welding process: Can body seam welding does not require bite brazing, which fundamentally eliminates the lead in the solder to food pollution and saves solder; the weld has high strength and good sealability; the amount of 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 can body plate, about 1.3~1.5 times, which is convenient for flanging, necking, and Sealing; the sealing quality is high, and the air tightness of the tank is good.

2.The manufacturing process and characteristics of soldering cans are as follows:

Panel cutting → corner cutting → end folding → rounding → soldering agent → hooking → flattening → brazing → flanging → back cover → inspection → packaging

Corner cutting is to cut off the two corners of one end of the can body blank, and cut two obtuse angles on the other end, so that when the can body is hooked to form a longitudinal seam, only two layers of iron sheet are lapped at both ends of the can body to facilitate flanging and sealing. At the same time, it is beneficial for the solder to penetrate into the joints in the can.

This process has been basically eliminated as a food can due to the problem of lead pollution. This article will not focus on it.

3.The manufacturing process and characteristics of the bonding tank The bonding tank body is bonded by a polymer (such as polyethylene, nylon, etc.) adhesive, heated to 130°C-150°C, and the molten adhesive is applied to the tank The lap joints of the body are heated, pressurized, and cooled to make the seams tightly bonded.

The process flow is:
Panel cutting → corner cutting → end folding → round → applying adhesive → overlapping or hooking → flattening → flanging → back cover → inspection → packaging

The characteristics of the process are: saving solder, eliminating lead pollution to food, no soldering solution, no damage to the tinplate of tinplate; chrome plate can be used, low raw material cost; full board printing, no need to leave blank welds, shape Beautiful; hot melt adhesive has low melting point, low energy consumption, and low operating cost; the bonding tank has poor heat and water resistance, and is currently mainly used for the packaging of solid or powdery contents.

People’s life and production are inseparable from packaging, because packaging has multiple functions. How to choose good quality tinplate tins, food tins, tea tins, gift tins, cookie tins? We can choose from the following aspects?

(1) Selling functional packaging is like a silent salesman. Good packaging can attract consumers ‘attention and stimulate consumers’ purchases. The sales function of packaging is achieved through packaging design. Excellent packaging design, with its exquisite shape, reasonable structure, eye-catching trademarks, decent text and bright colors and other artistic language, directly stimulates the purchase desire of the consumer lunch, and leads to purchase behavior. Some packaging also has potential value, such as beautiful and suitable packaging containers, which can be used to hold other items after the contents are used up. Uniquely shaped containers and beautifully printed decorations can not only increase the selling price of goods, and promote the sale of goods. At the same time, it can also be collected as an art appreciation.

(2) convenience function modern product packaging can bring many conveniences to people, which plays an important role in improving work efficiency and quality of life. The convenient function of packaging should be reflected in the following aspects.

①Convenient production for mass-produced products, packaging should meet the needs of mechanization, specialization and automation of production enterprises, taking into account resource capacity and production costs, and increase labor productivity as much as possible.

②Convenient storage and transportation for the quality and volume (size, shape, etc.) Of each packaging container, the convenient loading and unloading of various transportation vehicles should be considered for stacking; also consider that the quality of manual loading and unloading of goods generally does not exceed 40% of the worker’s weight (limited to about 20kg), etc .; At the same time, it should also consider the storage and stacking method of storage and transportation into warehouses, shops, and residences during circulation indoor decoration and storage during the process.

③ Convenient use of suitable packaging should make consumers feel convenient when opening, using, storing and storing. Such as carton sealed with adhesive tape, cans, spray packaging, portable packaging, etc., In a concise language or icon, to explain the precautions and methods of use to consumers to facilitate the use.

④Convenient handling means that some packages have the function of repeated use. For example, the recycling of various materials, glass bottles for beer and beverages, and the recycling of packaging waste (paper packaging, wooden packaging, metal packaging, etc.) Are convenient for environmental protection and conducive to resource conservation.

(2) Protection function the protection function of the packaging is the most basic and the most important function. It should protect the product from damage andloss. In the circulation process of goods, the factors that cause harm to them are: environmental conditions, such as temperature, humidity, gas, radiation, microbial insects, rodents, etc., Which may damage the packaging and harm the product; human factors, the goods are transported, during storage, due to careless or improper operation, the goods are damaged by shock, vibration, or fall, or they are crushed due to too many stacked layers. Therefore, according to factors such as the shape, characteristics, transportation environment, sales environment and other factors of different products,The most appropriate materials, reasonable design of packaging containers and technologies should be given to the packaging to provide sufficient protection functions to protect the safety of the products inside, and the special use of dangerous goods packaging, pay attention to prevent its damage to the surrounding environment and people and creatures.

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

(3) 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.
