2. Good sealing performance
3. Reduction of tin
4. Provide an effective source of iron
5. Recyclable, reusable, in line with international environmental requirements and future product trends
6. Durable, well protected, not deformed, shockproof, fire-resistant, and able to withstand high temperatures and pressures
Due to these properties, tin cans provide a closed system that completely isolates environmental factors in addition to heat. Colorful food deteriorates due to light, oxygen, and moisture, and does not fade due to aroma penetration or become contaminated by environmental odors. The stability of food storage is superior to other packaging materials, and the preservation rate of vitamin C is high, and the preservation of nutrients is also good.
Based on the imminent implementation of the international environmental management standard ISO-14000, tin cans with low pollution, recyclability, and resource saving characteristics will have broader development space in future packaging applications.
