The leather paper composite bubble bag is made of PE material.

PE material, also known as polyethylene, is a thermoplastic resin obtained by polymerization of ethylene. It is insoluble in general solvents at room temperature, with weak water absorption and good electrical insulation.

PE material can be said to be food grade, but there are also non food grade PE materials, because it depends on whether the PE raw material particles and production process are cast or blown. PE materials can also be made into food grade plastic, mostly used for disposable lunch boxes. At low temperatures, there will be no harmful substances, but if heated significantly, PE material products will release toxic substances, so it is generally not recommended to use PE material disposable products.
