A composite structure generally includes a polyolefin foam sheet and a film in adherence with the foam sheet. The film includes a blend of polyethylene and a thermoplastic elastomer. The elastomer includes a copolymer or terpolymer having a styrenic component and a rubbery component, the rubbery component having at least one carbon-carbon double bond. The rubbery component makes up at least about 70 wt. % of the thermoplastic elastomer. The resultant composite structure has a coefficient of friction ranging from about 0.5 to about 2.0, as measured at the upper surface of the film.

1. A composite structure comprising:a. a foam sheet comprising polyolefin; and b. a film having a thickness ranging from about 1 to about 20 mils and also having an upper surface and a lower surface in adherence with a surface of said foam sheet, said film comprising a blend of polyethylene homopolymer or copolymer and at least two different thermoplastic elastomers, each of said thermoplastic elastomers comprising a copolymer or terpolymer comprising a styrenic component and a rubbery component, said rubbery component having at least one carbon-carbon double bond and comprising at least about 70 wt. % of said thermoplastic elastomer, wherein, said Mm in adherence with said foam sheet results in a coefficient of friction ranging from about 0.5 to about 2.0 as measured at said upper surface of said film.
