The main material of COACE's K2B Food Film Heat Sealant contains vinyl acetate monomer in the molecular chain, which reduces the crystallinity of polyethylene and further improves the heat sealing performance of the composite film.
COACE's W1L is polyethylene as the base material grafted with MAH, and polar side groups are introduced into the non-polar chain. It is an compatibilizer for multilayer coextruded composite films.
