A masking film includes an adhesion layer that includes a blend of hydrogenated styrene block copolymer and low density polyethylene. The adhesion layer has an outer adhesion surface configured to contact a substrate. The outer adhesion surface has an average surface roughness Ra of between 100 nm and 350 nm, and an average spacing between peaks Sm of between 20 &#x3bc;m and 150 &#x3bc;m. The masking film also includes a release layer on a side of the adhesion layer opposite the outer adhesion surface.

Masking film for protecting sensitive substrates

A film for use as an interleaf between substrates includes a first side having a first micro-embossed surface and a first formed pattern, a second side having a second micro-embossed surface and a second formed pattern, a basis weight of between about 35 gsm and about 80 gsm, a Low Load Thickness of between about 150 micrometers and 400 micrometers according to the Low Load Thickness Test, and a flexural stiffness of between about 150 grams and about 500 grams according to the Circular Bend Stiffness Test.

Films for use as interleaves between substrates

Films may be used as interleaves between hard and non-compressible surfaces such as surfaces of sheets or plates made of glass, metal, such as steel, polycarbonate, and/or poly(methyl methacrylate). The films may be embossed and/or may include a foamed core layer having a plurality of micro-voids. In particular, the films may include a polyolefin, a basis weight of between about 30 gsm and about 70 gsm, an embossed thickness of between about 150 microns and 800 microns, and a stiffness of between about 150 grams and about 750 grams according to the Circular Bend Stiffness Test.

An illustrative aspect of the invention provides a film comprising a release layer defining a first outer film surface and an adhesion layer defining a second outer film surface opposite the first outer film surface. The adhesion layer comprises a hydrogenated styrene block copolymer with a styrene content in a range of about 30% to 40% by weight. In some embodiments, the adhesion layer may further comprise low density polyethylene (LDPE). In some embodiments, the adhesion layer may further comprise LDPE and high density polyethylene (HDPE).

Surface protection film

A coextruded multilayer film laminate featuring a polyolefin based formulation which closely matches the mechanical performance criteria of a plasticized PVC film is disclosed. This film is particularly suitable for use as a replacement film for plasticized PVC in a variety of medical and non-medical applications. The multilayer films of the present invention offer a particular set of mechanical properties, normally associated with plasticized PVC, including easy stretch, high degree of recovery, low fatigue and minimal permanent set. Moreover, these polyolefin based formulations do not contain any known or suspected carcinogenic compounds and may be produced at costs that are highly competitive with the costs associated with a conventional, plasticized PVC film.

PVC replacement film

A composite structure having a fibrous mat with perforated film coverings vacuumed formed on both sides of the fibrous mat. The composite structure is affixed between a structural foam and a soft foam to create a component part for use in applications such as automotive trim parts.
