Abstract

The present disclosure is directed to a physically crosslinked, closed cell continuous multilayer foam structure comprising at least one foam polypropylene/polyethylene layer with a recycled polyolefin material layer. The multilayer foam structure can be obtained by coextruding a multilayer structure comprising at least one nonrecycled foam composition layer with at least one recycled foam composition layer, irradiating the coextruded structure with ionizing radiation, and continuously foaming the irradiated structure.
