ABSTRACT:
A surface treatment for ethylene/vinyl acetate copolymer film resulting in an elastomeric, heat sealable film which retains its transparency after release from 200 percent elongation. The treatment comprises irradiation and controlled surface hydrolysis and, optionally, subsequent attachment of mineral particulates to the surface of the film with or without the use of coupling agents.
