ABSTRACT:
A coextruded thermoplastic sheet, with high peel strength and suitable for thermoforming into a container, the sheet including a layer of acrylonitrile-methyl acrylate copolymer to act as a gas barrier and provide rigidity, thermoformability and printability, a structural layer of polyolefin to provide a moisture barrier and chemical resistance, and an intermediate tie layer of a radial butadiene/styrene teleblock copolymer to provide a strong bond between the acrylonitrile-methyl acrylate copolymer and polyolefin notwithstanding the differences in tendencies to shrink between the two materials.
