Abstract: The present invention relates to a film for packaging a product, particularly to an improved multilayer film having recycled polyolefin. Among the objectives of the present invention, it is desired to provide a flexible multilayer film which incorporates higher levels of recycled high-density polyethylene resin. The present inventors have found that at least one of the abovementioned objectives is achievable by a multilayer film having a first polyethylene layer, a second polyethylene sealant layer and sandwiched therebetween a core layer having recycled HDPE.

Abstract: 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.
