摘要：
A nonsealable, matt, hazy, biaxially oriented multilayer film comprising a base layer and at least one outer layer wherein the base layer contains a propylene polymer and the outer layer(s) contain(s) high-density polyethylene (HDPE) and a polypropylene polymer. The film has a haze value, measured in accordance with ASTM D 1003, of greater than 40. The film is useful, for example, in the production of laminates or as a backing film for an adhesive on coating.
