MOISTURE-PROOF LAMINATED FILM, LAMINATE AND PACKAGE

PROBLEM TO BE SOLVED: To provide a laminated film which uniformly has a moisture-proof property to moisture-absorbing contents or highly moisture-absorbing contents at high levels, to provide a laminate using the laminated film, and to provide a package whose content is packaged with the laminate. SOLUTION: This at least two-layered moisture-proof laminated film is characterized by disposing a mixture comprising polyvinyl alcohol (PVA) and a laminar silicate in a weight ratio (PVA/laminar silicate) of 85/15 to 75/25 as a coating layer (B) on one side of a substrate film (A) comprising a biaxially oriented polypropylene film. The laminate having a total thickness of ≤70 μm is prepared by applying a printing treatment to the coating layer side of the moisture-proof laminated film and then laminating an un-oriented polyolefin film to the coating layer. The package prepared by packaging a content with the un-oriented polyolefin film side of the laminate is characterized by satisfying a specific expression. COPYRIGHT: (C)2007,JPO&INPIT
