BREATHABLE, EXTENSIBLE FILMS MADE WITH TWO-COMPONENT SINGLE RESINS. |
摘要 |
<p>A film formed from a two-component single resin including two components, not blended or co-polymerized, but inter-polymerized. The two components may have different densities and/or different melt indexes, with the resulting resin having properties of a blend of the two components but with improved durability and improved cross-directional extension properties compared to a conventional blend. The two components may be linear low density polyethylene and a metallocene-catalyzed polymer, for example. The film may also include calcium carbonate to provide breathability. The film has a more uniform cross-directional gauge profile and can be extended more uniformly. The film has cross-direction extensibility at a low force, for example, between about 25% and about 50% at a force below 500 grams per 3 inches.</p> |
