POLYMERS POLYMER BLENDS AND ARTICLES MADE THEREFROM

摘要

Polymer compositions including an ethylene based polymer having a melt index of from about 0.1 g/10 min to about 5.0 g/10 min; a melt index ratio of from about 15 to about 30; a weight average molecular weight (Mw) of from about 20 000 to about 200 000; a molecular weight distribution (Mw/Mn) of from about 2.0 to about 4.5; and a density of from 0.900 to 0.920 g/cm. Films having a thickness of 1 mil show a difference between the maximum seal strength and the minimum seal strength over the ranges of temperatures between 95.0°C and 140.0°C of < l.OOx lO grams/cm.
