Abstract: A silicone-free release film comprises a linear ethylenic polymer having a density from 0.865 to 0.900 g/cc and an index of polydispersity of less than 5.0 and yields a maximum release force value of 39 g/cm at a film thickness of 0.10 to 0.15 mm in an adhesive peel test. The film is useful in manufacturing rolls and sheets of pressure-sensitive adhesive tape.

Abstract: High clarity optical and safety glass laminate interlayer films and optical laminates are described. The films and their laminates comprise very low density polyethylene and/or its copolymers, preferably polymerized with metallocene catalysts, and modified with additives, such as coupling agents, clarifying or nucleation agents, UV-light absorbers, pigment or color concentrate, and IR-light blockers.

Abstract: The present invention is a film formed from an acrylate blend. The preferred blend is a film comprising components (a and b), component (a) being an ethylene butyl acrylate copolymer (EBAC) which is less than about 95 percent by weight of a total weight of components (a and b), wherein the EBAC has a content of acrylate groups from about 8 to about 36 percent by weight of the total weight of the EBAC; and component (b) being an ethylene methyl acrylate copolymer (EMAC) which is greater than about 5 percent by weight of the total weight of components (a and b), wherein the EMAC has a content of acrylate groups from about 8 to about 42 percent by weight of the total weight of the EMAC. The invention further includes a process for manufacturing this film for use as an interlayer in laminates comprising the steps of mixing the melt of thermoplastic polymer resins to form an ethylene butyl acrylate/ethylene methyl acrylate blend and forming the ethylene butyl acrylate/ethylene methyl acrylate blend of thermoplastic resins into a film for use as an interlayer in laminates. The invention still further includes a laminate comprising at least two sheets and at least one interlayer, the interlayer(s) being in between the sheets and wherein the interlayer is comprised of the film described above. The invention still further includes a laminate comprising an acrylate film laminated between two laminae wherein the film and the laminate have properties similar to PVB and laminates made with PVB, respectively.
