    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: A shim stack foaming die for making foam slabs comprises a plurality of shims that are layered together under pressure to form a shim stack, wherein the shims combine to collectively define a plurality of die orifices in a working face, to define a main body of the shim stack foaming die, and also to define a plurality of die cavity that is fluidly connected to the plurality of die orifices. And articles foamed from the shim stack foaming die have found wide use in various applications, thermal or acoustic insulation, reinforcing layers and/or space-filling layers, and so on.
