PROBLEM TO BE SOLVED: To prepare an extrusion-foamed expanded sheet excellent in shock absorption, in moldability, and in peelability, and to provide a method for manufacturing the same, a molding made of the same, and a tray for fruits and vegetables. SOLUTION: The extrusion-foamed expanded sheet is made of a resin composition (i) containing a polystyrene resin (a) and a styrene/conjugated diene copolymer or its hydrogenated copolymer (b). The copolymer (b) has an HDA hardness, measured by a durometer type A, of not more than 90. The extrusion-foamed expanded sheet has a density of 0.03-0.2 g/cm<SP>3</SP>and exhibits a partial compression displacement of not less than 0.60 mm under a 1 kgf load. The molding and the tray for fruits and vegetables are thermoformed out of the expanded sheet. COPYRIGHT: (C)2004,JPO&NCIPI |
