A laminate includes a multilayer outer film, which includes a first barrier layer and polyolefin layer on both sides of the first barrier layer, and a multilayer middle film, which includes a second barrier layer and polyolefin layer on both sides of the second barrier layer. The polyolefin layer of the multilayer outer film towards the multilayer middle film and/or the polyolefin layer of the multilayer middle film towards the multilayer outer film is metallized with a metal selected from aluminum, nickel, chromium, or combinations thereof. A process can be used for preparing the laminate and an article can include the laminate.

Provided herein are films comprising a core layer sandwiched between an outer layer and a scaling layer. The film has a seal initiation temperature at 5 N/15 mm between about 82° C. and about 88° C., a 1% secant modulus m MD between about 300 MPa and about 400 MPa, and plateau seal strength at between about 16 and about 17 N/15 mm. While the outer layer and core layers comprise polyethylene compositions, the sealing layer comprises a polyethylene blend. The polyethylene blend comprises a plastomer and a polyethylene composition in an amount equal to or less than 50 wt %.

A film is described comprises a (meth)acrylic polymer and a polyvinyl acetal (e.g. butyral) resin. In some embodiments, the film has a glass transition temperature (i.e. Tg) ranging from 30° C. to 60° C. In some embodiments, the film has a gel content of at least 20% or greater. In some embodiments, the film has an elongation at break of at least 175%. The film typically comprises photoinitiator as a result of the method by which the film was made. The film may be a monolithic film or a layer of a multilayer film.

Disclosed are multilayer films with at least one MDO substrate.

This invention relates to an anisotropic multilayer film and the process of making a multilayer film, wherein a supercritical blowing agent is introduced to at least one layer, wherein at least one layer comprises 10 to 100 percent by weight LLDPE with a melt index of 0.2 to 2 g/10 min. The film in this invention can have a surface with an average Sheffield smoothness, according to TAPPI T 538, of less than 100. The film in this invention can have a puncture propagation tear resistance, in accordance with ASTM D2582, greater than 500 g/mil.

The present invention relates to an ethylene-vinyl alcohol copolymer (EVOH) resin composition, an EVOH film formed therefrom, and a multilayer structure containing the same. The surface roughness of the EVOH resin composition is the peak material volume (Vmp) between 0.0008 and 10 μm.sup.3/μm.sup.2. The EVOH of the invention can reduce the torque output during processing, and can obtain the EVOH film with excellent appearance.

The present invention relates to an ethylene-vinyl alcohol copolymer (EVOH) resin composition, an EVOH film formed therefrom, and a multilayer structure containing the same. The core height difference (Sk) of the surface of the EVOH resin composition is between 0.6 and 2.0 μm, and the overall standard deviation of Sk is between 0.05 and 0.55. The invention can reduce the torque output during processing to achieve the effect of energy saving, and can also improve the stability during output to obtain a better film appearance.

A stitch-bonded tape or other directionally stabilized product wherein stitch-bonding is carried out by overstitching yarns stitched through a sheeting or other surface substrate in conjunction with the introduction of high tenacity lay-in yarn elements disposed longitudinally in the machine direction of formation to provide strength in the length direction. The overstitching yarns secure the lay-in yarns in place relative to the surface substrate. An adhesive or other coating is disposed in covering relation to the lay-in yarn elements.

Multilayer oriented shrink films include a skin layer and a base layer; the skin layer being on one side of the base layer, characterized in that the skin layer comprises at least one amorphous styrene-butadiene block copolymer and the base layer has a thickness greater than said skin layer and includes a polypropylene terpolymer, a polybutene-1 copolymer, a polypropylene elastomeric copolymer and at least one copolymer from the group consisting of styreneethylene/butene-styrene triblock copolymers, styrene-ethylene/propylene-styrene triblock copolymers, styrene-ethylene/butene diblock copolymers, styrene-ethylene-propylene diblock copolymers, and combinations of two or more of said triblock and diblock copolymers.
