摘要

PROBLEM TO BE SOLVED: To provide a strongly bonded vapor deposition film having at least a vapor deposition layer comprising an inorganic oxide on a film base material comprising a plastic material, especially reinforced in the adhesion of the film base material and the vapor deposition layer, causing no delamination even if subjected to heat sterilization treatment, for example, retorting or boiling treatment and having gas barrier properties, and also to provide a method for production thereof.;SOLUTION: When producing the strongly bonded vapor deposition film by providing at least the vapor deposition layer comprising the inorganic oxide on at least one side of the film base material comprising the plastic material, plasma post-treatment using magnetron discharge is applied to the surface of the vapor deposition layer under treatment unit pressure of 8-100 Pa.;COPYRIGHT: (C)2005,JPO&NCIPI
