ABSTRACT:
A peelable protective film is disclosed, which is processed from a composition comprising 100 parts by weight of an ethylene/methyl methacrylate copolymer, from 0.01 to 0.1 part by weight of an inorganic filler, and from 0.01 to 1.0 part by weight of a slip agent. The protective film of the invention, when wrapped around articles having a tacky surface, exhibits good adhesion to the substrate and has a low peeling strength and, therefore, can be readily peeled away as required.
