The pros and cons of tin cans

The inherent qualities of a tin can make for an excellent packaging material. This kind of canned fruit is not only common in the canned food and beverage manufacturing industry. Companies also use them to preserve industrial, household and promotional products. Metal food containers have developed into one of the most widely used packaging materials in the world.

Tin cans can not only block gases such as air, oxygen, water vapor, carbon dioxide, etc., but also block light, especially ultraviolet light, so it will not cause deliquescence, deterioration, decay and fading of the contents and changes in flavor.

The use of canned food has high heating and cooling efficiency, which can improve the effect of high-temperature sterilization and rapid cooling, and it is possible to achieve in-can cooking of the contents.

It has good ductility and can realize high precision and high speed production for complex forming processing. For example, the production speed of a tinplate three-piece can production line can reach 3600 cans/min. Such high productivity enables metal containers to meet the high demands of consumers at a lower cost.

A closed system that completely isolates environmental factors, the food that avoids color is deteriorated by light, oxygen, and moisture, and does not fade due to the permeation of aroma or pollution by environmental odor. The stability of food storage is better than other packaging. Material, the preservation rate of vitamin C is high, and the preservation of nutrients is also good. Based on the imminent implementation of the international environmental management standard ISO-14000, tinplate cans with low pollution, recyclability and resource-saving characteristics will have broader development space in future packaging applications.

Can be made into various shapes of empty cans, suitable for industrialized large-scale production. The disadvantage is that it cannot be reused, and the contents cannot be seen after sealing, which is inconvenient for consumers to choose.
