Document Type and Number:
Japanese Patent JP5040055
Kind Code:
B2
Abstract:
A biaxially oriented polyamide laminate film having a layered structure of A/B, A/B/A or A/B/C, layer A having no projections with a height of 0.27 mu m or higher on the surface, or having a density of projections with a height of 0 . 27 mu m or higher on the surface of 200 projections / mm<2> , and the film exhibiting a maximum dimensional change of 4% or less during immersion in 95 DEG C hot water, a maximum dimensional change of 6% or less after withdrawal from the hot water, and a maximum dimensional change of 4% or less after heat treatment in dry hot air at 160 DEG C; and a process for producing the same. This film reduces the differences in physical properties in the width direction that occurs in a tenter and exhibits excellent adhesive properties, resistance to fatigue from flexing and operability, and can be provided economically.
