PLASTIC FILMS |
摘要 |
<p>A plastic film having a desirable balance of physical properties is prepared using a pseudohomogeneous linear low density polyethylene (Ildpe) resin on a blown film extrusion line. The Ildpe used in this inventi on must have a melt index, I2, of from 0.4 to 0.8 grams per 10 minutes, a base resin density of from 0.915 to 0.919 grams per cubic centimeter and a copolymer/homopolymer (COHO) ratio of from 3 to 9. The film must be prepared under specific extrusion conditions using a specific annular extrusion die. The film of this invention has a dart impact strength of greater than 600 grams per mil and a machine direction tear strength of greater than 350 grams per mil and is suitable for the preparation of packaging and trash bags.</p> |
