SUBSTRATE FOR FOAMING ADIABATIC PAPER CONTAINER, SHEET FOR FOAMING ADIABATIC PAPER CONTAINER, AND FOAMING ADIABATIC PAPER CONTAINER

摘要

To provide a substrate for foaming adiabatic paper container in which top curl processability is improved and productivity of a paper container is enhanced by reducing generation of peeling at a seam part during manufacturing a foaming adiabatic paper container, and a sheet for foaming adiabatic paper container and a foaming adiabatic paper container using the same.SOLUTION: There is provided a substrate for foaming adiabatic paper container composed of a paper substrate mainly containing cellulose pulp and a water-soluble resin layer arranged on at least one surface of the paper substrate, and having a ratio tensile elastic modulus in a crosswise direction of 5.0 kN m/g or less, and an interlaminar strength measured by using an internal bond tester of 530 J/mor more. There are provided a sheet for foaming adiabatic paper container and a foaming adiabatic paper container using the substrate for foaming adiabatic paper container.SELECTED DRAWING: None
