Laminated foam sheet for thermoforming, method for producing laminated foam sheet for thermoforming, and food or packaging container

摘要

PROBLEM TO BE SOLVED: To provide a laminate expanded sheet for thermoforming capable of obtaining a formed body having a satisfactory appearance and capable of enhancing both of strength and heat resistance of an obtainable formed body.SOLUTION: A laminate expanded sheet for thermoforming 1 includes: a foam layer 2 made of a polyolefin-based resin; and a non-foam layer 3 made of a polyolefin-based resin, which is laminated on one surface 2a of the foam layer 2. The laminate expanded sheet 1 has not less than 35 MPa nor more than 95 MPa in tensile elasticity at 100°C, and not less than 180 MPa nor more than 450 MPa in tensile elasticity at 23°C. A ratio of a thickness of the non-foam layer 3 to a thickness of the foam layer 2 is not less than 0.025 nor more than 0.14.
