STYRENIC RESIN FOAM SHEET AND MOLDED CONTAINER FORMED THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a foam sheet reduced in the content of a styrene dimer/ trimer in extruding and foaming a styrenic resin to form a sheet and a molded container formed of the foam sheet. SOLUTION: A styrenic foam sheet reduced in the content of a styrene dimer/ trimer is obtained by extruding a styrenic resin to which an oxidation inhibitor is added to foam the same. The foam sheet is molded to obtain a molded container wherein the content of a styrene dimer/trimer in a styrenic resin foam layer is reduced.
