At the beginning of reform and opening up, the cost advantage of the mainland was huge. The tinplate manufacturing industry was transferred from Taiwan and Hong Kong to the mainland. In the 21st century, the Chinese Mainland joined the WTO global supply chain system, and exports increased dramatically. The canning industry began to blossom everywhere, and consumers were more likely to accept this packaging.
So why do I strongly recommend using tin cans packaging?
1. Diverse shapes
Packaging is not simply packaging. On the basis of meeting the basic packaging functions, designers hope to be more prominent in terms of shape, and the plasticity of materials is particularly important. Iron, on the other hand, has a natural advantage in plasticity and good ductility, which can be manufactured into various forms, such as rectangular, square, circular, irregular, etc. It has stronger plasticity and higher strength than others, such as plastic soft bags; What has better strength than him is not as malleable as him, such as wooden or paper boxes.
2. Safety
The majority of metal tin cans are made of tinned tinplate, which was the earliest metal discovered and widely used by humans. Tin is safe, and even large doses of tin are non-toxic. In ancient times, it was made into tin pots and tin vessels were used to hold food, which were exclusively used by nobles and nobles. In modern times, due to its safety and non-toxic properties, as well as its bactericidal, purifying, and fresh-keeping properties, it has been used as the inner layer of food and canned packaging, This is the origin of tinned tin cans.
3. High strength
Because the tinplate adopts T2-T4 hardness, the corresponding hardness is selected according to the different use scenarios. Because of its good resistance to compression and falling, it is generally used for tea, cookies Chicken rolls, drinks, etc. Such use scenarios require that the packaging strength is good, and the contents are not easily damaged. The soft package is very easy to crush tea, Chicken rolls, etc.
4. Environmental friendliness
The most popular event in the packaging industry recently is that Coca Cola has changed the classic green packaging of Sprite, which has a history of more than 60 years, to transparent packaging. Because green packaging requires special treatment during recycling, transparent packaging does not have such problems. In addition, with the gradual increase of the “plastic ban”, degradable and convenient recycling of tin packaging products is becoming increasingly popular. As a good student of energy conservation and emission reduction in the world, China’s dedicated iron product recycling electric furnace steelmaking reached a historic 200 million tons in 2021, an increase of 30% compared to the previous year.
As an environmentally friendly packaging, the industry has invested a lot of effort in reducing waste and saving resources. Currently, the 0.12mm “Crown Cap” has been put into the market, saving about 20% compared to the original 0.15mm thick material. The development of “lighter and thinner” tinplate packaging areas.
Peers in the same industry are making unremitting efforts to promote the widespread application of tinplate can packaging. For example, in order to solve the problem of rust, galvanized sheets have been derived, which have better rust and moisture prevention effects; Tinplate packaging plays an important role in the packaging field. It is the only one of all packaging materials that can meet the requirements of solid, liquid and gas packaging (chemical raw materials, food gifts, beverages, handicrafts, toys, gas spray).
