It is also used for the coating of foil to provide a heat-seal layer in multilayer film structures.
In whatever shape polyethylene is used, there is complete agreement in the excellent characteristics of this material. Polyethylene is a good insulator, it resists caustic materials, it is almost unbreakable and is environment-friendly.Polyethylene is reliable under every circumstance and it can easily deal with tropical temperatures as well as the frosty cold of the polar circle. This tough material is hard wearing.olyethylene is a good insulator, it resists caustic materials, it is almost unbreakable and is environment-friendly.
