One aspect of the present invention is a protection sheet for protecting a transparent sheet, the protection sheet including: a base material having a sheet shape; and a pressure-sensitive adhesive layer that peelably attaches the base material to the transparent sheet, wherein the pressure-sensitive adhesive layer contains an antistatic agent.

A multi-phasic polymer blend for energy activated edge banding adhesion to a substrate is described. While the blend may be used for adhering edge banding to straight substrates, the blend is preferred for adhering edge banding to contoured substrates. The outer, hard, structural layer of the edge banding is formed from a polypropylene component. The polypropylene component at least includes polypropylene and an optional energy adsorber. The inner adhesion layer of the edge banding is formed from a multi-phasic polymer blend that bonds the outer layer of the edge banding to the substrate. The multi-phasic polymer blend at least includes a polyamide component, a polyolefin component, and a modified polypropylene component. Both the outer and inner layers forming the edge banding may be tinted to conform or contrast with the color of the finished substrate.

A self-adhesive vapor-permeable membrane for use on a building, comprising a support that is permeable to air and water vapor, and a pressure-sensitive adhesive layer that is permeable to air and water vapor, and is secured to the underside of the support, wherein the membrane is noteworthy in that it comprises gas bubbles trapped between the support and the adhesive layer.

An encapsulant sheet suitable for encapsulating a light-emitting element in a self-luminous display, etc. A resin sheet having a polyolefin as a base resin, wherein the resin sheet is created as an encapsulant sheet for a self-luminous display or for a direct backlight, the melt viscosity of the encapsulant sheet, at a shear velocity of 2.43×10 sec.sup.−1 and measured at a temperature of 120° C., being 5.0×10.sup.3 poise to 1.0×10.sup.5 poise inclusive.

Self-adhesive product redetachable by extensive stretching comprises a pressure-sensitive adhesive comprising: a) an elastomer component, where i. the elastomer component comprises a hydrogenated polyvinylaromatic-polydiene block copolymer described herein, ii. the polydiene blocks are substantially fully hydrogenated, iii. the hydrogenated polyvinylaromatic-polydiene block copolymer has a construction described herein, and iv. the elastomer component comprises a hydrogenated diblock copolymer having a construction described herein, b) a tackifying resin component, c) optionally a plasticizer, d) optionally further adjuvants, and also at least one ply of a temporary carrier material.

A welding strip carrier film. The raw materials for the welding strip carrier film comprise, in percent by mass, 50-99% of a matrix resin, 0-50% of a tackifying resin, and 0-5% of an additive. The matrix resin is one or more of a polyolefin resin and an elastomer thereof, a polyester resin and an elastomer thereof, polyvinyl butyral, an ethylene-vinyl acetate copolymer, an ethylene-acrylic acid copolymer, an ionic polymer, polyamide, fluororesin, and modifiers thereof. The tackifying resin is one or more of rosin, hydrogenated rosin, a petroleum resin, a hydrogenated petroleum resin, a phenolic resin, and a terpene resin. The carrier film can be manufactured into a single-layer structure, and thus can have a support function while ensuring its bonding performance to a welding strip and a cell; and the carrier film would not be penetrated by a welding strip during lamination.
