FOAMED, LAMINATED POLYSTYRENE RESIN MULTI-LAYER BODY, CONTAINER MAIN BODY, FOOD PACKAGING CONTAINER, AND FOOD PACKAGE

摘要

PROBLEM TO BE SOLVED: To provide a foamed, laminated polystyrene resin multi-layer body which is excellent in low temperature impact resistance, gas-barrier properties, oil resistance, solvent resistance, recycling properties, and thermoforming properties such as deep drawing for a cup, a bowl, etc. SOLUTION: In the multi-layer body, a resin layer of an aromatic polyester resin 200 deg.C or below in flow beginning temperature under 4.9 kN load is laminated on one side of a foamed sheet or plate of a polystyrene resin at least 90 deg.C in Vicat softening point, and a resin layer of a polyolefin resin at least 10 KJ/m2 in Izod impact value is laminated on the other side of the foamed sheet or plate.
