Tin plate sheet is based on low carbon steel, and then coated with a thin layer of tin (usually 0.08 mm), which not only has an anti-corrosion effect, but also gives the tin plate sheet good gloss and workability.
When choosing a suitable tinplate can packaging, the first factor to consider is the nature of the product. Different types of products have different requirements for packaging. Taking food as an example, the main goal of food packaging is to keep food fresh, avoid external contamination, and extend the shelf life.
Tinplate is a thin steel plate with a tin-plated surface that has excellent antioxidant properties and is relatively low in cost. The tin coating of tinplate cans can prevent direct oxidation of metal to a certain extent, while effectively isolating air and moisture, providing a good storage environment for coffee.
Tin plate sheet is not essentially a single metal, but a composite material composed of steel and tin. Its main component is low-carbon thin steel plate with a thin layer of tin on the surface.
Main uses of tin plate sheet:
1. Food packaging
2. Beverage packaging
3. Cosmetic packaging
4. Chemical containers
5. Industrial parts and tools
6. Stationery and daily necessities
The main advantages of electrolytic tinplate sheet:
1. The thickness of the tin layer is uniform and easy to accurately control
2. Low tin consumption and material saving
3. The surface of the coating is smooth and suitable for fine printing
4. Strong corrosion resistance
5. Suitable for a variety of subsequent processing techniques
6. Better environmental protection
As one of the choices for food packaging, tin plate cans have many advantages, one of the important reasons is the extension of product shelf life. Tin packaging can effectively block the intrusion of light, moisture and oxygen, thereby reducing the impact on product quality.
Biscuits are a kind of snack food loved by consumers, and their shelf life is relatively long, so the requirements for packaging are also relatively high. In order to ensure the taste and freshness of biscuits and prevent moisture and deterioration, cookie packaging tin must have excellent sealing, barrier and durability.
The chemical properties of tin are relatively stable, and it has strong resistance to chemicals such as acids, alkalis, and salts, which means that it is not easy to react with other substances. Unlike iron, tin is not easy to rust, and it has high safety in food contact and does not produce substances harmful to the human body.
Depending on the different ink types, coating protection and storage conditions, the service life of the LOGO on the tin plate cans under normal conditions will vary. Generally, a properly protected tin plate cans LOGO can remain non-fading for 3 to 5 years in a cool and dry environment indoors.
Under standardized production and storage conditions, tinplate food cans will not release harmful substances. The tin coating and inner wall coating of tinplate food cans can effectively prevent direct contact between food and metal, avoiding the risk of food contamination.
