Zusammenfassung:	SE PRESENTAN PELICULAS DE POLIOLEFINA REVESTIDAS PARA ENVASES SELLADOS MEDIANTE CALOR QUE SE OBTIENEN MEZCLANDO POLIOLEFINA Y UNA ROSINA O RESINA CON UN ALTO PUNTO DE REBLANDECIMIENTO, PREFERIBLEMENTE HIDROGENADAS Y EXTRUYENDO LA MEZCLA RESULTANTE CON UN POLIMERO PARA FORMAR UNA PELICULA REVESTIDA. Coated polyolefine films for heat sealed packaging and twist wrapping are obtained by blending polyolefine and a rosin or resin of high Ring and Ball softening point, preferably hydrogenated, and extruding the resultant blend with polymer to form a coated film.
