Document Type and Number:
WIPO Patent Application WO/2022/137867
Kind Code:
A1
Abstract:
Provided are a heat-fusable laminated oriented film having sufficient mechanical properties, high durability in a moist and hot environment, high adhesion at a lamination interface, and a good bonding state at the time of thermal bonding, and a wound roll thereof. In the heat-fusable laminated oriented film according to the present invention, heat-fusable layers including a heat-fusable polyolefin resin are provided by coextrusion so as to be in direct contact on both sides of a base material layer composed of a resin composition including 60-99.9% by mass of a polyamide resin or a polymethylpentene resin and 0.1-40% by mass of a modified polyolefin resin, and where the longitudinal, width, and thickness directions are defined as an X axis, an Y axis, and a Z axis, respectively, the film is stretch-oriented in the X-axis and/or Y-axis direction, and a thermal deformation rate at 150°C in both the X-axis and the Y-axis directions is 3% or less.
