The invention of the metal can revolutionized food preservation, most notably significantly extending the shelf life of food. As a sealed packaging method, metal cans can isolate air and bacteria while simultaneously sterilizing food at high temperatures, significantly reducing the risk of spoilage and extending its shelf life.

The materials used for metal packaging cans vary depending on the application. Typically, metal packaging cans are made of materials such as tinplate, aluminum, and tin-free steel (TFS). Each of these materials has different properties and is suitable for different packaging needs.

The protective effect of the tin layer is limited, especially when storing acidic foods, where there is a risk of tin corrosion. Therefore, during the production process, a protective coating or lining is often added to the inner surface of tinplate cans to further prevent direct contact between food and metal.

Combined with the analysis in the previous article, it can be seen that the production of metal cans does rely mainly on tinplate plate. Whether from the mechanical properties, chemical stability of the material, or from its anti-corrosion and decorative characteristics, tinplate plate is an ideal choice for making metal cans.

Modern applications of metal tins: Metal tins are used to package a variety of products, including food, beverages, pharmaceuticals, cosmetics, chemical products, paints, etc. Its main function is to provide a strong, sealed packaging solution that can extend the shelf life of the product.

Epoxy resin coating can not only prevent metal from direct contact with food, avoid metal corrosion or contamination of food, but also extend the shelf life of food. Therefore, the inner wall coating of many food and beverage cans contains BPA.

The main component of tinplate cans is steel, on which a thin layer of tin is coated to prevent rust and corrosion. Aluminum cans are made entirely of aluminum, a lightweight metal with a density of about one-third that of steel.

In daily life, our common packaging products are mainly paper packaging, plastic packaging, and tin can packaging. With the increasingly serious environmental pollution, people's environmental protection awareness has gradually increased, and the tin box and tin can packaging have gradually received people's attention. So, what impact does the tin box and tin can packaging have on environmental protection?

The metal cans design of health products is different from the large metal cans design of other products. It is neither a medicine nor a general food. Health care products have the function of strengthening the body. It is a special product between medicine and food. In the design of the empty metal cans, there are specific standards. A qualified health product empty metal cans have the following elements in terms of design:
