Beschreibung
Zusammenfassung:	PURPOSE:To enhance the adherence of metallized film and prevent the peeling, deterioration and the like of the film in the subsequent process from occurring by a method wherein metal is deposited on one side of laminate, which has two surface layers respectively having specific constitutions. CONSTITUTION:The metallized laminate concerned is produced by depositing metal on the layer A of laminate, which consists of more than one layer including the layers A and B as surface layer. The layer A is made of composition, which is prepared by blending 20-150 pts.wt. of straight-chain low density polyethylene having the density of 0.925-0.937 with 100 pts.wt. of crystalline polypropylene-based resin. The layer B is made of crystalline propylene-alpha-olefin copolymer, the crystalline melting point of which is lower by 10 deg.C or more than that of the crystalline polypropylene-based resin, which is used in the layer A. Thus, the adhesion strength of the metallized film is remarkably improved as compared with the conventional metallized polypropylene-based film.
