METALLIZED WRAPPING FILM

摘要

A metallized wrapping film having low water vapor transmittance and low oxygen transmittance, in which the adhesion of the metallic layer to the base film is strong, and which has a heat-sealing property, comprises a plastic base film; a heat-sealing layer formed on one surface of said base film; and a metallic layer formed on one surface of said base film opposite to said surface on which said heat-sealing layer is formed. The metallic layer consists essentially of 70 - 99% by weight of aluminium and one or more elements selected from those having an atomic number of 12 - 30 excluding aluminium.
