<P>PROBLEM TO BE SOLVED: To provide an extrusion foamed sheet having excellent cushioning properties, moldability, peelability, etc., a method for producing the extrusion foamed sheet, an extrusion foamed sheet molded product and a tray for vegetables and fruits. <P>SOLUTION: The extrusion foamed sheet is the sheet of a resin composition (i) containing a polystyrenic resin (a), a polyethylenic resin (b) having 0.87-0.92 g/cm<SP>3</SP>density and a copolymer (c) of styrene and a conjugated diene or its hydrogenated material. The copolymer (c) of the styrene and conjugated diene or its hydrogenated material has ≤90 HDA value of a durometer type A hardness, 0.03-0.2 g/cm<SP>3</SP>density of the extrusion foamed sheet and ≥0.60 mm extent of partial compressive deformation when 1 kgf load is applied on the extrusion foamed sheet. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
