Abstract
LA PRESENTE INVENCION MEJORA EL RENDIMIENTO DE LOS CIERRES LATERALES Y/O DE ALETAS (16) DE LAS BOLSAS DE PLASTICO, POR EL USO DE RESINAS QUE TIENEN UNA ESTRECHA DISTRIBUCION DE PESOS MOLECULARES O DE POLIDISPERSION. EL COMPORTAMIENTO DEL CIERRE LATERAL Y/O DEL CIERRE DE ALETA DE UNA BOLSA DE PLASTICO MEJORA CUANDO SE UTILIZAN PANELES DEL CUERPO (25, 26) QUE COMPRENDEN UNA PRIMERA RESINA Y, OPTATIVAMENTE, UNA SEGUNDA RESINA. LA PRIMERA RESINA SE PREPARA PREFERENTEMENTE EN PRESENCIA DE UN UNICO CATALIZADOR IN SITU. LA PRIMERA RESINA TIENE UNA POLIDISPERSION DE APROXIMADAMENTE 1 A 4, UN INDICE DE FUSION DE ENTRE 0,2 Y 20, Y UNA RELACION DE FLUJO EN FUSION (I 20 /I 2 ) DE 12 A 35 APROXIMADAMENTE. EL USO DE LAS PRIMERAS RESINAS HACE QUE LOS CIERRES LATERALES Y DE ALETAS SEAN MAS FUERTES, RESISTENTES Y CON MENOS PROBABILIDAD DE FUGAS. LA SEGUNDA RESINA ES UN POLIMERO COMO EL LDPE, EL LLDPE, O MEZCLA DE LOS MISMOS. EN LOS PANELES DEL CUERPO QUE COMPRENDEN TANTO UNA PRIMERA COMO UNA SEGUNDA RESINA,LA PRIMERA RESINA PUEDE CO - EXTRUIRSE CON LDPE O LLDPE COMO CAPA DELGADA DEL PANEL DEL CUERPO, O MEZCLARSE LA PRIMERA RESINA CON EL LDPE Y/O EL LLDPE.
