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.

Pattern printing on food packaging cans is a precise and systematic process, which usually includes the following main steps: 1. Pattern design and plate making 2. Metal surface treatment 3. Printing and drying 4. Topcoating and packaging

Tinplate sheet prevents rust by plating a layer of tin on the surface of the steel plate to form a physical barrier to prevent the steel from contacting with air and moisture. The thickness and uniformity of the tin layer play a vital role in the anti-rust performance of tinplate sheet.

Reasons why tinplate packaging cans are prone to corrosion: 1. The protective effect of the tin layer is limited ● Uneven thickness of the tin layer ● Scratches or damage to the tin layer ● Chemical reaction between the tin layer and the contents 2. Corrosion susceptibility of the steel substrate 3. The influence of the use environment on corrosion ● High humidity environment ● Acid and alkali environment ● High temperature environment ● Contact with different chemicals 4. Electrochemical corrosion ● Contact between different metals ● The presence of electrolyte solution

● Soak a soft cleaning cloth or sponge in warm water and add a small amount of neutral detergent, and gently squeeze out any excess water. ● Place a sponge or cloth inside the cookie jar and gently wipe from the bottom, making sure every corner is clean. For stains on the corners, use a soft brush or cotton swab for detailed cleaning.

Tin plated on the surface of tinplate is a relatively safe metal and is widely used in the food packaging industry. As a low-toxic metal, tin is stable and non-volatile at room temperature, and it is difficult to react chemically even when in contact with food.

During World War II, there was a shortage of tinplate sheet, which prompted people to look for alternative materials to meet packaging needs. During this period, aluminum became the main alternative material for the manufacture of seamless can-shaped packaging containers.

Based on the specific needs of tinplate cans for food packaging, offset printing is the most suitable printing method for most food packaging. It can provide high-precision printing effects, bright colors, and is suitable for mass production. At the same time, the cost of offset printing is relatively low, which can meet the needs of most food companies.
