  • Polyolefin foam/film composite structure and method for making same
    Publication number: 20030138622
    Abstract: A composite structure includes, a polyolefin foam in adherence with a film. The film comprises ethylene/styrene interpolymer, homogeneous ethylene/alpha-olefin copolymer, and various blends of such materials. Advantageously, the film in adherence with the foam sheet results in a coefficient of friction ranging from about 0.5 to about 2.0 as measured at the upper surface of the film.
