HYBRID INTERPOLYMER FILM POUCH |
摘要 |
<p>A pouch for containing a flowable material, said pouch being made from a film in tubular form and having transversely heat-sealed ends, said film being made from at least one layer of a material comprising about 50 to about 100 parts by weight of a hybrid interpolymer of ethylene and a C3-C20 alpha-olefin made by a polymerization process using both a metallocene catalyst and a Zeigler-Natta catalyst, the hybrid interpolymer having a density of from about 0.910 to about 0.940 g/cm3, a melt index of from about 0.1 to about 2.0 dg/min, and a melt strength of greater than about 3.5 Centi Newtons as determined using a Goettfert Rheotens unit at 190.degree.C. and from 0 to about 50 parts by weight of a high-pressure polyethylene having a density of from about 0.916 to about 0.924 g/cm3 and a melt index of from about 0.01 to about 10 dg/min. Also described is a process for making such pouches.</p> |
