Advantages of tinplate
Tinplate cans are packaging materials that meet environmental protection requirements
Existing containers include iron cans, aluminum cans, paper and plastic containers. The recycling characteristics of these containers are different, but iron cans are better than other packaging materials in terms of recycling.
Based on the imminent implementation of the international environmental management standard ISO-14000, tinplate cans with low pollution, recyclable and resource-saving features will have a broader development space in future packaging applications:
1. Low pollution:
Tinplate, the main raw material in tin can containers, is actually environmentally friendly and can be decomposed naturally, because when tin cans exist in the environment, they can be oxidized naturally and return to the original iron oxide state, returning to nature, so scrap iron cans Stacking can be analyzed by time, and no residue will cause environmental pollution. At the same time, the production of iron cans cannot damage the logging wood and will not destroy the ecological balance.
2. Recyclable:
The iron can body has a characteristic that its packaging materials do not have—it can be adsorbed by magnets, so that the iron can waste can be separated by magnetic force by using a magnetic separator, and recycling can be easily achieved by using this feature. The effect of 80% iron cans in the garbage dump. The discovery of environmental protection, but the use of iron cans is safer, more hygienic, and effectively reduces the amount of garbage, which has a direct impact on recycling operations and express benefits.
3. Save resources:
In terms of removing other pollution residues on iron cans, shredder equipment has been developed, which can effectively remove more than 98% of pollutants and provide good quality scrap iron scraps. In addition, the United States also pointed out that the existence of aluminum easy-open lids is beneficial to the recycling of scrap iron, because it can reduce the amount of hot metal used in steelmaking and reduce the overall cost of steel manufacturing. In addition, in terms of energy saving, the report pointed out that compared with iron ore production, the use of tinplate scraps to produce steel can save about 230m² of natural gas per ton of scrap iron scraps, so the recycling process of iron cans can reduce the impact on the global environment. With the impact of energy, it is in line with future product trends.
