Abstract

PURPOSE: To prepare the titled resin sheet having specific expansion ratio, thickness and folding endurance, and suitable for the manufacturing of a food container having excellent apperarance and heat insulation, by extruding a mixture of a rubber-containing styrene resin and a chemical foaming agent in the form of a sheet.
CONSTITUTION: The objective resin sheet having an expansion ratio of 1.1W2.1, thickness of 0.1W1mm and folding endurance (accordance to JIS P8115) of ≥5, is prepared by adding a chemical foaming agent (e.g. propane) to a styrene resin (e.g. copolymer of polystyrene and α-mehylstyrene) containing 1.5W8wt% rubber component (e.g. natural crepe rubber) and extruding the composition in the form of a sheet preferably with a T-die.
