Modified polyolefin film with stable twist retention, dead fold properties and barrier characteristics

Abstract

The present invention is directed to modified polyolefin films with stable twist retention and dead fold properties to be employed in wrapping in general, and particularly in wrapping small items. The films produced by the present invention exhibit improved moisture vapor barrier and oxygen barrier properties. The inventive films are obtained by extrusion and stretching of a ternary mixture comprising (1) isotactic polypropylene; (2) high density polyethylene; and (3) a glassy amorphous low molecular weight resin. Multilayer films are also provided.
