Abstract

La presente invención se refiere a películas poliolefínicas modificadas, con especiales características como: estabilidad en la torsión y doblez muerto, que se emplean - sobre todo - para envolver productos pequeños mediante torsión. Compuesto por una mezcla ternaria de: polipropileno isotáctico, polietileno de alta densidad y una resina vítrea, amorfa y de bajo peso molecular. Dado por tres etapas: 1.- Mezcla homogénea de los tres componentes; 2.- Extrusión de la mezcla para obtener una lámina y; 3.- Estiramiento longitudinal y transversal para obtener la película biaxialmente orientada.The present invention refers to modified polyolefinic films, with special characteristics such as: stability in torsion and dead bending, which are used - above all - to wrap small products by torsion. Composed of a ternary mixture of: isotactic polypropylene, high-density polyethylene and a low molecular weight amorphous, glassy resin. Given by three stages: 1.- Homogeneous mixture of the three components; 2.- Extrusion of the mixture to obtain a sheet and; 3.- Longitudinal and transverse stretching to obtain the biaxially oriented film.
