摘要：
Disclosed herein are physically crosslinked, closed cell continuous multilayer foam structures that include a coextruded foam layer containing at least one of polypropylene and polyethylene and a crosslinked, coextruded cap layer containing at least one of polypropylene and polyethylene. The multilayer foam structure can be obtained by coextruding a multilayer structure comprising at least one foam composition layer and at least one cap composition layer, irradiating the coextruded structure with ionizing radiation, and continuously foaming the irradiated structure.
