PROTECTIVE FILMS.

摘要

Multilayer protective films that adhere well to many different surfaces and can be removed without leaving residues are provided. The films consist of a polyolefin backing layer(s) and an adhering layer consisting of an ethylene unsaturated ester copolymer layer containing a resin. The films have good tensile strength and stiffness at minimum thickness and can be produced by blown film and cast processes, mono and co-extrusion. The films are particularly useful for protecting automobiles during transportation and storage, a masterbatch of the resin in an ethylene polymer or copolymer to facilitate co-extrusion of the multi layer films is also provided.
