Nowadays, many foods need to be packaged.

Food packaging in the market is now colorful and there are endless packaging materials. Food packaging materials are closely related to food safety. Food packaging is as important as food. Therefore, food packaging materials must not be taken care of.
Currently, tinplate cans are recognized by the world as "the safest and most environmentally friendly products." This is because the tinplate material used in tin cans has good impermeability and opacity, which can effectively prevent the contents from being oxidized by light and prevent the intrusion of contaminants. Therefore, it is safe, hygienic and healthy. In addition, the more important point is that the tin can is the most environmentally friendly container because it can be recycled and can be recycled and used in line with the national energy conservation and environmental protection requirements. Moreover, if the iron cans are placed in the natural environment, after several years of wind and rain, it will naturally oxidize, crush or integrate into the soil.

This can not be said that with the rapid, steady and healthy development of the metal packaging industry. It is inseparable from the long-term emphasis on food safety.
