Abstract

A process for preparing packaging films based on crystalline olefin polymers, obtained by stereospecific catalysis, and more particularly based on polypropylene with a high proportion of crystallinity, characterized in that the support film is subjected to a modification treatment of the surface and the film thus treated is coated with a layer suitable for heat-sealing the film and consisting of polyamides that have a melting or softening point of between 50 and 120ºC and are soluble in ordinary organic solvents.
