Title:
POLYAMIDE LAMINATE FILM AND PRODUCTION METHOD FOR SAME
Document Type and Number:
WIPO Patent Application WO/2017/217452
Kind Code:
A1
Abstract:
[Problem] To provide: a polyamide laminate film that has excellent uniformity of thickness and comparatively little variation in physical properties in a 0 degree direction, a 45 degree direction, a 90 degree direction, and a 135 degree direction; and a production method for the polyamide laminate film. [Solution] A polyamide laminate film in which there is a copolymer polyester resin layer on at least one side of a polyamide film. (1) The difference between the maximum value and the minimum value for the stress at 5% elongation during uniaxial tensile tests in four directions represented by 0 degrees, which is a specific direction from any point on the polyamide film, and 45 degrees, 90 degrees, and 135 degrees clockwise from said direction is 35 MPa or less. (2) The difference between the maximum value and the minimum value for the stress at 15% elongation during uniaxial tensile tests in the four directions is 40 MPa or less.
