Abstract

METODO PARA PRODUCIR UNA PELICULA DE POLIPROPILENO BIAXIALMENTE ORIENTADA Y REVESTIDA. SE EXTRUYE UNA PELICULA BASE DE POLIPROPILENO Y SE ORIENTA EN DIRECCION LONGITUDINAL. SE RECUBRE POR EXTRUSION AL MENOS UNA SUPERFICIE DE LA PELICULA ORIENTADA CON UNA SOLA CAPA DE RECUBRIMIENTO DE COPOLIMERO DE ETILENO-ACETATO DE VINILO PARA FORMAR UNA PELICULA RECUBIERTA. SE PRECALIENTA LA PELICULA RECUBIERTA A UNA VELOCIDAD DE CALENTAMIENTO DE 2,8 A 22 C POR SEGUNDO. POR ULTIMO SE ORIENTA LA PELICULA PRECALENTADA RECUBIERTA RESULTANTE EN DIRECCION TRANSVERSAL. SE UTILIZAN ESTAS PELICULAS TERMOPLASTICAS PARA ENVASADO, FORMANDO UN CIERRE TERMICO DESPEGABLE.
