Aluminum cans are formed by deep drawing and rolling, and printed with trademarks. Pour the beverage into the assembly line, immediately cover the prepared upper cover, roll it up and seal it. There must be some loss of carbon dioxide in the middle.

In that kind of one-off ignition, the gas fuel is highly volatile, and after injecting liquefied fuel, it automatically plugs the upper body that has been coated with glue, and also loses some fuel.

Aluminum's strong rival in packaging industry comes from PET material, which can be made into strange appearance by injection mold, while aluminum material is relatively difficult, but the prices of the two materials are quite different. PET is affected by the price of oil, while aluminum can be recycled by itself, which reduces the material cost and attracts the attention of environmental protection organizations. ?

Europe, America and some areas with active consumption of cans are constantly improving the recovery rate of aluminum cans and aluminum packaging materials. Countries that start early in recycling no longer argue about the recycling value of waste aluminum cans, but become daily work, while countries that start late are making great efforts to do it.
