Tinplate cans meet environmental protection requirements for packaging materials

- Apr 11, 2018 -

The existing containers include iron cans, aluminum cans, paper and plastic containers. These containers have different recycling characteristics, but the iron cans are superior to other packaging material containers in the recycling process.


Based on the international environmental management standard ISO-14000, tinplate cans with low pollution, recyclable, and resource-saving characteristics will have broader development space for future packaging applications:


1. Low pollution:


The tinplate, the main raw material in the tin container, is in fact environmentally harmless and can be naturally decomposed, because when the tin can exist, it can naturally oxidize and return to the original iron oxide state, returning to nature, so the scrap iron can The stacking can be decomposed by time and will not cause environmental pollution. At the same time, iron cans need not be felled to make iron cans, and the ecological balance will not be destroyed.


2. Recyclable:


The tin can itself has a characteristic that other packaging materials do not have - it can be adsorbed by the magnet, so that the magnetic can be used to separate the can from the waste by the magnetic separator, and this characteristic can be used to easily recover the garbage. The effect of 80 percent iron cans. The invention of the environmental protection cover not only makes the use of iron cans safer and healthier, but also effectively reduces the amount of waste, and has direct and obvious benefits for recycling operations.


3. Provincial resources:


In the removal of other contaminated residues from the cans, chopper equipment has been developed to effectively remove more than 98% of pollutants and provide good quality scrap iron. In addition, the United States also pointed out that the presence of aluminum easy-opening lids facilitates the recycling of scrap iron because it can reduce the amount of Hot Metal used in steelmaking and reduce the overall steel manufacturing cost. In terms of energy saving, the report pointed out that the use of tin scrap to produce iron and steel produces about 230m3 of natural gas per ton of scrap compared to iron ore production. Therefore, the recycling process of tin cans can reduce the global environment. Impact with energy, in line with future product trends.
