POLYSTYRENE-BASED RESIN LAMINATED FOAMED SHEET, VESSEL AND MANUFACTURING METHOD OF POLYSTYRENE-BASED RESIN LAMINATED FOAMED SHEET

摘要

PROBLEM TO BE SOLVED: To provide a polystyrene-based resin laminated foamed sheet to which beautiful print can be given without generating unevenness of printing, and which shows excellent mold release and gives a product without blocking when the sheets are laminated on each other.

SOLUTION: The polystyrene-based resin laminated foamed sheet is made by integrally laminating a 5 to 550μm thick mono-layered or multi-layered polystyrene-based resin film on at least one surface of the polystyrene-based resin foamed sheet wherein the outermost film layer of the polystyrene-based resin films contains 0.01 to 3 wt.% of silicone oil having a coefficient of kinematic viscosity exceeding 150,000 centistokes at 25°C.
