FOAMING THERMAL INSULATION SHEET AND FOAMING INSULATION CONTAINER USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a foaming thermal insulation sheet which can be printed attractively, and a foaming insulation container using the same.SOLUTION: A foaming thermal insulation sheet comprises: base paper; a foaming layer which consists of a low melting thermoplastic synthetic resin film laminated on the outside surface of the base paper and can foam by heat treatment; a foaming stable layer laminated on the outside surface of the foaming layer and consisting of a high melting thermoplastic synthetic resin film which does not foam by the heat treatment; a printing layer formed on the outside surface of the foaming stable layer by printing; and a high melting thermoplastic synthetic resin film which is laminated on the inside surface of the base paper and does not foam by the heat treatment.
