  • Publication number: 20060093812
    Abstract: The invention relates to metallized, biaxially oriented opaque polypropylene multilayer film comprising at least three layers consisting of a base layer, a first metallized covering layer, and of a second sealable covering layer on the opposite side. The first covering layer contains at least 80% by weight of a propylenelethylene copolymer, which has an ethylene content of 1.2 to <2.8% by weight and a propylene content of 97.2 to 98.8% by weight, a melting point ranging from 145 to 160° C., and a melting enthalpy ranging from 80 to 110 J/g. The first covering layer has a thickness of at least 4 ?m and the base layer contains vacuoles. The thick covering layer can also be formed from a combination consisting of an intermediate layer with a thin covering layer.
