Biaxial orientierter, metallisierbarer Polypropylenfilm, ein demgemäss metallisierter Film und einen solchen Film verwendendes Laminat

摘要

A biaxially oriented polypropylene film to be metallized comprises a surface layer made of a polypropylene resin having an endothermic main peak by crystal fusion in a range of 155 to 163 DEG C and a heat of crystal fusion of 20 to 90 J/g, being laminated layer at least on one side of a base layer made of isotactic polypropylene; and the wetting tension of the surface layer being 33 to 55 mN/m. A metallized biaxially oriented polypropylene film, comprises the biaxially oriented polypropylene film onto which a thin metal film is laminated. A laminate can be obtained using the metallized biaxially oriented polypropylene film.
