THERMOFORMING POLYSTYRENIC RESIN MULTILAYERED FOAMED SHEET

摘要

PROBLEM TO BE SOLVED: To provide a thermoforming polystyrenic resin multilayered foamed sheet obtained by laminating an impact-resistant polystyrenic resin sheet to a polystyrenic resin foamed sheet obtained by extrusion foaming and capable of being thermoformed into a deep-drawn molded article such as a bowl or cup excellent in lip strength. SOLUTION: In the thermoforming polystyrenic resin multilayered foamed sheet wherein the polystyrenic resin foamed sheet and the impact-resistant polystyrenic resin sheet are laminated, the thickness of the thermoforming polystyrenic resin multilayered foamed sheet is 1.5-3.0 mm, the weight basis/m2 thereof is 340-410 g/m2 and the tensile load (JIS K7127) thereof is 850-150 N in both of extrusion and width directions.
