  • Publication number: 20120219776
    Abstract: A multilayer film that includes at least three layers and is made up of a first layer, a second layer and a third layer, where the first layer is in between the second and third layers. The first layer contains a blend of a second polyolefin and interpolymer resin particles that include a styrenic polymer intercalated within a first polyolefin. The second layer directly contacts a surface of the first layer and includes a first thermoplastic resin. The third layer directly contacts a second surface of the first layer and includes a second thermoplastic resin. The first thermoplastic resin and second thermoplastic resin can be the same or different.

  • Publication number: 20120217682
    Abstract: 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.

  • Publication number: 20120219814
    Abstract: Methods of improving polyethylene stretch film that include providing interpolymer resin particles, forming a polyethylene blend composition by blending from about 0.1 to about 10 percent by weight based on the weight of the blend composition of interpolymer resin particles into one or more polyethylene resins; and forming a film from the polyethylene blend composition. The interpolymer resin particles contain a styrenic polymer intercalated within a first polyolefin, where 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.

  • Publication number: 20120219813
    Abstract: A film containing a polymer composition that includes from 0.1 to 60% by weight of interpolymer resin particles containing a styrenic polymer intercalated within a first polyolefin and from 40 to 99.9% by weight of at least one second polyolefin. The first polyolefin is present at from 20% to 80% by weight based on the weight of the particles, has a VICAT softening temperature greater than 60° C. and a melt index of from 0.3 to 15 g/10 minutes (Condition I, 190° C., 2.16 kg). The styrenic polymer is present at from 20% to 80% by weight based on the weight of the particles. The interpolymer resin particles have a gel content ranging from 0 to 5% by weight based on the weight of said interpolymer resin particles, a VICAT softening temperature ranging from 85° C. to 115° C., and a melt index value ranging from 0.1 to 6.0 (Condition I).

  • Publication number: 20060047077
    Abstract: 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.
