Is pe food bag material safe?
The pe food bag material is safe and does not need heating. There is no complicated process in the production of PE bags, so there is no need to use production additives. This kind of PE plastic bag will produce a decomposed organic gas after heating, which is harmless in itself and will not produce harmful substances simply by heating. However, when PE polyethylene plastic bags are modified or regenerated, unknown toxic substances will be produced.
Polyethylene or polyethylene (abbreviated as PE; IUPAC (polyethylene or poly (methylene)) is the most common plastic. By 20 17, the annual output of polyethylene resin exceeded 65438+ 1 100 million tons, accounting for 34% of the total plastic market. Its main application is packaging (plastic bags, plastic films, geomembranes, containers including bottles, etc.). ).)。 Many kinds of polyethylenes are known, most of which have the chemical formula (C2H4) n. Polyethylene is usually a mixture of ethylene-like polymers with different n values. Polyethylene is a thermoplastic; But after modification, it can become thermosetting plastics (such as crosslinked polyethylene).
