Title:
MULTILAYER FILM AND PACKAGING MATERIAL
Document Type and Number:
WIPO Patent Application WO/2011/152015
Kind Code:
A1
Abstract:
Disclosed are: a multilayer film which has good impact resistance, flex resistance and pinhole resistance and therefore can have a smaller thickness than those of conventional multilayer films; and a packaging material. The multilayer film (100) involves a repeatedly laminated part (130). The repeatedly laminated part (130) is produced by laminating a first layer (131) and a second layer (132) alternately in a repeated manner. The first layer (131) contains a polyamide resin (which is different from an elastomer) as the main component. The second layer (132) contains a copolymer of an olefin hydrocarbon having 2 to 4 carbon atoms and a monomer containing a vinyl group as the main component.
