A conductive film includes an elongated release film and a plurality of conductive adhesive film pieces provided on the release film. Then, the plurality of adhesive film pieces are arranged in a longitudinal direction X of the release film. For this reason, the adhesive film piece can be set to an arbitrary shape. Accordingly, it is possible to attach the adhesive film piece to adhesive surfaces having various shapes and to efficiently use the adhesive film piece.

A cling foil comprising an outermost adhesive layer comprising a pressure sensitive adhesive, an outermost release layer, the outermost release layer comprising a release material, and a foil layer positioned between the outermost adhesive layer and the outermost release layer.

The invention provides a frameless photo-energy assembly including a photo-energy converter, wherein an edge of the photo-energy converter is sealed by an adhesive tape, comprising an adhering layer for adhesion and cushioning; and an aging-resistant protective layer. The adhering layer is used to contact the edge of an article and comprises: a substrate layer; optionally, a first adhesive layer and a second adhesive layer situated at both sides of the substrate layer oppositely, wherein the first adhesive layer being used to be contact with the article. The aging-resistant protective layer is situated on the adhering layer, which comprises: an optional primer layer, which is situated on the adhering layer; and a film layer, which is situated on either the primer layer or the substrate or the second adhesive layer. The invention further provides an adhesive tape for sealing an edge of an article and an article made of the assembly.

The invention relates to a separating film based on polyolefins or ethylene copolymers with a content of organic and optionally inorganic pigment and at least one UV stabilizer. The separating film has a transmission percentage between 5 and 20% in the range from 400 to 700 nm and a transmission percentage of <2% in the range from 300 to 500 nm. Such separating films have the advantage that marking regions applied onto membranes which can be found below the separating film remain detectable, and adhesives which can be found below the separating film are effectively protected from UV light and premature aging by the addition of inorganic and organic pigments and UV stabilizers. The invention further relates to composite structures of corresponding separating films and adhesives, to water-tight membranes with coatings made of adhesive and separating films, and to uses of corresponding membranes for sealing structures against water.

Films with structured adhesives and structured liners are described. Associated methods of making such films are also described. Films as described herein may be particularly suitable to providing adhesive films with structured adhesives with readily recyclable liners.

A pressure sensitive adhesive article is described comprising a pressure sensitive adhesive in contact with the release layer. The release layer comprises a thermoplastic polymer and a block copolymer additive having the general structure: A[LB]n wherein A is a polyorganosiloxane block, L is a covalent bond or a divalent linking group B is independently a C16-C70 alkyl group, and n is at least 1. In other embodiments, compositions are described comprising a thermoplastic polymer the described block copolymer additive; as well as methods of making a release composition.

Disclosed are an oxygen barrier film, a food wrapper including the same, and a method of preparing the oxygen barrier film.

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 μm and 150 μm. The masking film also includes a release layer on a side of the adhesion layer opposite the outer adhesion surface.

Film constructions and articles including the film constructions, wherein a film construction includes: a backing (or an adhesive layer) having a first major surface and a second major surface; and a release layer disposed on the first major surface of the backing (or adhesive layer), wherein the release layer includes polylactic acid.

Adhesive sheets that can adhere to both a smooth surface and a rough surface with sufficient adhesive force and that exhibits smooth visual appearance after adhesion regardless of a surface to be applied are described. In particular, adhesive sheets including a rigid sheet having a thickness of 80 μm or greater and 2 mm or less; and a first pressure-sensitive adhesive layer disposed on one surface of the rigid sheet, the first pressure-sensitive adhesive layer having a thickness of 40 μm or greater and 1.2 mm or less and including a microstructured surface including irregularities are described.
