Diecuts are configured for permanent closing of holes and have a carrier comprising an assembly of at least two polymeric films. An upper film of the at least two polymeric films has a basis weight of at least 1.0 kg/m.sup.2 and a lower film of the at least two polymeric films consisting of at least two layers, wherein a first layer is in the form of a polymeric film and faces the upper film, and a second layer is in the form of a functional layer with a side of the lower film, facing away from the upper film, bears an applied adhesive composition.

The present invention relates to a method for producing a multi-layer substrate, said substrate comprising a multifunctional coating, and to the use of the substrate produced by this method.

Optical interlayers, laminated composites and improved methods for manufacturing the optical interlayers and laminated composites are provided. An optical interlayer film comprises at least one surface having an embossed surface pattern having at least two channels extending in at least two non-parallel directions. The channels have a depth of greater than about 20 ?m. The surface pattern allows for the removal of air between the interlayer and the outer laminate sheets, thereby establishing the requisite seal therebetween while minimizing premature edge sealing. The laminated composites are particularly useful for safety glazing in a variety of applications, such as automobiles, airplanes, trains, or other modes of transportation, display devices, windows in homes and other buildings, building facades, cabinets, and/or weight bearing architectural structures such as stairs and floors.

An interlayer structure having a cellulose ester layer for use in structural laminates is described herein. The cellulose ester layer provides rigidity and support to multilayer interlayers comprising an array of different layers. Due to the diverse properties of the cellulose ester layers, the present interlayers can be useful in producing structural laminates having high stiffness and which possess good optical clarity for a variety of applications, including outdoor structural applications.

A laminated glass, includes a glass plate, a polymer layer, and a functional device layer, wherein, the polymer layer is located between the glass plate and the functional device layer; the laminated glass further optionally includes another polymer layer, which is located at the other side of the functional device layer, opposite to the glass plate; the polymer layers each independently include polymer, which is selected from crosslinked ethylene-vinyl acetate copolymer, polyolefin thermoplastic elastomer, and thermoplastic polyurethane elastomer.

A laminated transaction card may comprise post-consumer polyethylene with a thickness of at least 30% of a thickness of the laminated transaction card. A first polymer-based layer comprising polyvinyl chloride is coupled to a first surface of the core layer by a first adhesive layer. A second polymer-based layer comprising polyvinyl chloride is coupled to a second surface of the core layer by a second adhesive layer. The first adhesive layer and the second adhesive layer comprise an adhesive formulated to bond the post-consumer polyethylene and the polymer-based layers.

A dressing for treating tissue with negative pressure may be a composite of dressing layers, including a release film, perforated gel layer, a perforated polymer film, a manifold, and an adhesive cover. A method of manufacturing the dressing may comprise providing a first layer, such as the gel layer, on a substrate, perforating the first layer on the substrate to create a plurality of apertures in the first layer, and creating an index of the plurality of apertures in the first layer. A laser can be calibrated based on the index. A second layer, such as the polymer film, may be coupled to the first layer, and a plurality of slots can be cut in the second layer with the laser. Each of the slots can be cut through one of the apertures in the first layer based on the index.
