1. Opaque; 2. Good sealing performance; 3. Tin land reduction; 4. Provide a source of available iron; 5. Recyclable and reusable, in line with international environmental protection requirements and future product trends; 6. Strong, good protection, no deformation, impact resistance, fire resistance, high temperature and high pressure resistance.
There is a layer of food ink inside the tinplate, which also has a great guarantee for our food. The surface printing inks used in tinplate are environmentally friendly, can directly contact food, and are harmless to the human body. Food ink can pass FDA, SGS, etc., and can directly contact food, so that children can eat at ease, and adults can eat with confidence.
Tin cans have the above properties, so tin cans provide a closed system that is completely isolated from environmental factors other than heat. Color-avoiding foods deteriorate due to light, oxygen, and moisture, and will not fade due to fragrance penetration, nor will they become flavored due to environmental odor infiltration pollution. The food storage stability is better than other packaging materials, the preservation rate of vitamin C is higher, and the nutrients are better preserved. Based on the international environmental management standard ISO-14000, tinplate cans with low pollution, recyclability and resource saving will have broader development space in packaging applications in the future.
