Abstract:
The disclosed film backing has a multilayer extensible substrate with a securing adhesive that can secure to a surface and a tab to stretch the extensible substrate to remove the securing adhesive from the underlying surface. Stretching the extensible substrate will easily release the adhesive from the underlying surface. Therefore, a strong adhesive can be used. The multilayer extensible substrate includes an elastic layer forming the core adjacent to a plastically-deforming layers forming the skin to minimize the elasticity of the overall construction.
Abstract:
A composite film comprises first and second layers. The first layer comprises a first copolymer of monomers comprising tetrafluoroethylene, hexafluoropropylene, and vinylidene fluoride, wherein the first copolymer contains at least 35 mole percent of vinylidene fluoride monomer units. The second layer is disposed on the first layer, and comprises a second copolymer comprising 50 to 83 weight percent of ethylene monomer units and at least 17 weight percent of alkyl (meth)acrylate monomer units represented by the formula (I) wherein R 1 is H or methyl, and each R 2 is independently an alkyl group having from 1 to 4 carbon atoms. Methods of making the composite film and articles including it are also disclosed.
Abstract:
Polymeric multilayer film comprising at least two adjacent layers each exhibiting a random network of strands and connective regions. The polymeric multilayer films are useful, for example, for tape and graphic articles.
Abstract:
Polymeric multilayer films having an array of openings extending between the first and second major surfaces of the film, and a thickness greater than 50 micrometers, wherein the openings each have a series of areas through the openings from the first and second major surfaces ranging from minimum to maximum areas, and wherein the minimum area is not at at least one of the major surfaces. Polymeric multilayer films described herein are useful, for example, for wound dressings and graphics films.
Abstract:
Presently describes are articles, such as liquid reservoirs, comprising a liquid repellent surface.

In some embodiments, the component comprises a thermoplastic polymeric material. In some favored embodiments, the component is a removable liquid reservoir or liner. In some favored embodiments, the component is a collapsible liquid reservoir or liner. The spray application system typically further comprises a gravity-fed spray gun.
Abstract:
The present invention relates to printed hook components for hook and loop mechanical fasteners, and other components such as on diaper chassis and other personal hygiene articles, and methods for making the same. The hook component comprises an organic polymer, a laser-sensitive agent, and a laser-induced print on the hook component created by the interaction of electromagnetic radiation with the laser-sensitive agent. The hook component can be used in a variety of applications, including mechanical fastening devices for personal hygiene articles such as diapers, adult incontinence pads, and medical gowns.
Abstract:
The present application generally relates to multi-layer sealing films, methods of making such films, materials for inclusion in such films, retroreflective sheeting and articles including such films, and methods of making retroreflective sheeting and articles including such films. The multi-layer sealing film may include two or more layers. One exemplary embodiment of a two-layer film includes a first layer including a thermoplastic polymeric material including reaction products of alkylene and reaction products of at least one non-acidic comonomer and a second layer including one of a polyolefin, a polyester, a polymethyl methacrylate, a polyamide, a polycarbonate, an ethylene-methacrylic acid, and a polyurethane. In some embodiments, at least one of the layers of the multi-layer sealing film has an elastic modulus of at least 3.5 x 10 5 kPa and the flexural rigidity of the retroreflective article is less than about 4.0 x 10 -8 N•m 2 .
Abstract:
Methods of protecting graphic substrates are disclosed. One method includes coating a hardcoat composition onto a substrate to form a hardcoat layer, curing the hardcoat layer to form a cured hardcoat layer, disposing a thermoplastic layer onto the cured hardcoat layer to form a transparent hardcoat composite film, and laminating the transparent hardcoat composite film onto a graphic substrate with heat and pressure. The thermoplastic layer softens and adheres to the graphic substrate to form a protected graphic substrate. Stain and scratch resistant cured hardcoat composite films are also disclosed.
