Abstract

LA INVENCION SE REFIERE A UNA PELICULA PROTECTORA TERMOFORMABLE CONSTITUIDA POR AL MENOS SEIS CAPAS COEXTRUIDAS DE RESINAS TERMOPLASTICAS UNA DE LAS CUALES ES DE POLIAMIDA Y ESTA DIRECTAMENTE EN CONTACTO CON UNA CAPA DE UNA ALEACION DE COPOLIMERO ETILENO-ALCOHOL VINILICO (EVOH), ESTANDO LIGADAS LAS DOS CAPAS EXTERNAS DE POLIOLEFINA A LA CAPA DE POLIAMIDA Y A LA CAPA DE ALEACION MEDIANTE UNA CAPA DE AGLOMERANTE DE COEXTRUSION. ESTA PELICULA SIRVE A LA FABRICACION DE EMBALAJES TERMOFORMADOS DE PRODUCTOS ALIMENTICIOS PERECEDEROS. LA INVENCION SE REFIERE TAMBIEN A UN EMBALAJE TERMOFORMADO PARA LA CONSERVACION DE LOS PRODUCTOS ALIMENTICIOS PERECEDEROS DURANTE UNA DURACION DE AL MENOS TRES MESES, RESISTENTE AL AGUA CALIENTE Y TRANSLUCIDA, CARACTERIZADA EN QUE EL ESPESOR DE SUS PAREDES ES INFERIOR A 250 (MU)M Y PREFERENTEMENTE COMPRENDIDA ENTRE 180 Y 250 (MU)M.
