Abstract

Una película encogible que comprende una mezcla de copolímeros de etileno y una o más alfa-olefinas que tienen de 3 a 12 átomos de carbono formadas in-situ, teniendo dicha mezcla un índice de fusion dentro de la escala de aproximadamente 0.2 a aproximadamente 3.5 gramos por 10 minutos; un régimen de flujo de fusion en la escala de aproximadamente 50 a aproximadamente 175; un peso molecular en la mezcla de aproximadamente 90,000 a aproximadamente 225,000; un régimen de Mw/Mn de por lo menos aproximadamente 8, y una densidad en la escala de 0.910 a 0.940 gramos por metro cubico, estando formada dicha película encogible a un régimen de soplado en la escala de aproximadamente 2:1 a aproximadamente 6:1 y que tiene las siguientes propiedades: (i) a aproximadamente 135 degree C un encogimiento de por lo menos aproximadamente 50% en la direccion de la máquina y un encogimiento de 0o positivo en la direccion transversal. (ii) la tension de fusion es de 0 o de kilo pascales positivos; y (iii) una tension de enfriamiento de por lo menos aproximadamente 0.35 x 103 kilopascales.
