Abstract:
A semi-aromatic polyamide film having a thermal shrinkage factor in the longitudinal direction of the film, SMD, of −1.0 to 1.5% and a thermal shrinkage factor in the width direction of the film, STD, of −1.0 to 1.5% as measured under the conditions of 250° C. and 5 min, a tensile breaking elongation of 70% or more in the longitudinal direction and the width direction, and a haze of 14% or less.
