Summary: | A physically crosslinked, closed cell continuous multilayer foam structure comprising at least one polypropylene/polyethylene coextruded foam layer is obtained. The multilayer foam structure is obtained by coextruding a multilayer structure comprising at least one foam composition layer, irradiating the coextruded structure with ionizing radiation, and continuously foaming the irradiated structure. |
