    摘要: Methods of improving the physical properties of a polyolefin film that include providing interpolymer resin particles, forming a blend composition by blending from about 0.1 to about 25% by weight based on the weight of the blend composition of interpolymer resin particles into a second polyolefin; and forming a film from the blend composition. The interpolymer resin particles are made up a styrenic polymer intercalated within a first polyolefin. The first polyolefin is present at from about 20% to about 80% by weight based on the weight of the particles and the styrenic polymer is present at from about 20% to about 80% by weight based on the weight of the particles.

    摘要: This invention relates to the preparation of plastic film by the extrusion of a blend of from 95.5 to 98.5 weight % of a homogeneously catalyzed linear low density polyethylene and from 1.5 to 4.5 weight % of a selected high pressure low density polyethylene having a melt index, I2, of from 0.1 to 0.8 grams per 10 minutes. The films produced by this invention have good optical and physical properties and may be extruded at high rates.
