According to the International Energy Agency, the global steel industry accounts for approximately 8% of global industrial carbon emissions, making it the largest contributor to carbon emissions among all industries. Although tinplate sheet production may have slightly lower carbon emissions than conventional steel production, its overall carbon footprint remains relatively large.

As a steel-based material, tinplate sheet possesses the inherent strength and durability of steel. Compared to other packaging materials such as plastic and paper, tinplate sheet effectively protects canned foods from external physical impact or compression.

Tinplate itself is one of the top choices for food-grade packaging materials. 1. It's made from a low-carbon steel base plate electroplated with a tin layer, which effectively prevents rust from coming into contact with food. 2. If combined with a food-grade coating (such as epoxy phenolic or polyester coating), its safety fully meets international standards.

The tin-plated layer on the surface of tinplate plate can not only resist the erosion of air and moisture, but also prevent the metal from directly contacting food. Especially in acidic foods (such as canned fruit and canned tomatoes), the protective performance of tinplate plate is particularly important.

Due to the moisture-proof, light-proof and anti-oxidation properties of tinplate food packaging cans, it can provide a relatively stable and closed environment for tea, thereby delaying the loss of tea flavor. Therefore, the use of tinplate food packaging cans can significantly extend the shelf life of tea.

The tin coating of food packaging cans can not only prevent food from directly contacting the iron cans, but also reduce the penetration of oxygen, thereby reducing the oxidation effects that canned beef may suffer during long-term storage.

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

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.

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.
