Abstract
A biaxial stretch oriented and heat-set film made of thermoplastic is described. The film has, on at least one of its surfaces, a surface roughness (R.sub.a) of greater than 0.003 .mu.m. The surface roughness is the result of an integral texturing of the polymeric film surface. The polymer in the textured area shows essentially the same morphological state as the polymer in the interior of the film itself.
