Title:
FILM AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2019/167861
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a film that combines flexibility, moisture permeability, and water resistance while having the mechanical strength necessary to be used as a film and in essence is a film characterized by satisfying condition 1 or 2 when a layer having a polyester-based elastomer as the main component, containing particles, and having a porosity of 10 to 50% (inclusive) is taken as layer A and a layer having a polyester-based elastomer with an equilibrium absorption of 1.0% or higher as the main component and having a porosity of 0 to less than 10% is taken as layer B. Condition 1: The film has a layer A; the content of particles in layer A is 50 to 140 mass parts when the entire resin component in layer A is taken to be 100 mass parts; and the film does not have a layer B. Condition 2: The film has a layer A and a layer B.
