Abstract

UN PROCEDIMIENTO PARA PRODUCIR UN ESTRATIFICADO PARA ENVASAR RECUBRIENDO UN MATERIAL DE SOPORTE QUE IMPARTE RIGIDEZ CON AL MENOS UNA CAPA DE UN MATERIAL TERMOPLASTICO ESTANCO A LOS LIQUIDOS. SE MEZCLA POLIETILENO LINEAL DE BAJA DENSIDAD Y POLIETILENO DE BAJA DENSIDAD Y SE ALIMENTAN A UN DISPOSITIVO EXTRUSOR EN DONDE LA TEMPERATURA DE LA MEZCLA SE ELEVA HASTA UN VALOR IGUAL Y SUPERIOR A SUS PUNTOS DE FUSION TRAS LO CUAL LA MEZCLA FUNDIDA SE TRATA ADEMAS MECANICAMENTE Y FINALMENTE SE EXTRUYE A TRAVES DE UN CABEZAL DE EXTRUSION RECTO SOBRE LA SUPERFICIE DE LA CAPA DE SOPORTE.
