RESIN FOAMED SHEET AND CONTAINER

摘要

PROBLEM TO BE SOLVED: To obtain a container having high heat resistance and high oil resistance from a highly moldable resin foamed sheet. SOLUTION: This resin foamed sheet comprises the polymer alloy of a styrenic resin (a rubber-modified styrenic resin, etc.), with a thermoplastic resin having a melting point of 100-300 deg.C. The polymer alloy may contain a compatibilizing agent, and may have a sea-island structure having an average island particle diameter of 0.01-10μm. The thermoplastic resin includes olefinic resins, polyester-based resins, polyamide-based resins, and polycarbonate-based resins. The foamed sheet has a surface gloss of >=10%, a foaming magnification of 1.1-3 times, an average pore film number/unit sheet thickness of 1-50 films/mm and a thickness of about 0.3-2 mm.
