Abstract

Embodiments introduced in a process for preparing a biaxially oriented film, which comprises extruding a sheet or tube from a film composition and subsequently orienting the sheet or tube in a machine in a direction transverse to the machine and in the direction of the machine, characterized in that a mixture of a stereoregular polypropylene and not more than 25% by weight of a non-hydrogenated styrene polymer is extruded, at a temperature of 200ºC to 275º c, to produce a non-transparent film, and the film is stretched in both directions at a temperature of 100ºC to 150ºC to at least four times its dimension in each direction to produce a transparent biaxially oriented film.
