A method of manufacturing a foamed polyolefin sheet which comprises the steps of laminating a film of noncross-linked thermoplastic resin free from a cross-linking agent to at least one surface of a cross-linked polyolefin base sheet containing a thermally decomposable foaming agent or a polyolefin base sheet containing the above-mentioned foaming agent and a cross-linking agent, and carrying out the thermal foaming of said film-fitted sheet while placing it on a supporting member under atmospheric pressure with the film-laminated surface of the polyolefin sheet being in contact with said supporting member.

Method of manufacturing a composite foamed polyolefin sheet

The present invention provides a foamable polyolefin composition comprising a polyolefin, a crosslinking agent, a blowing agent decomposable at temperatures higher than the decomposition temperature of said crosslinking agent and a gas trapping agent as well as a method for manufacturing foamed polyolefin from said foamable polyolefin composition.
