Title:
発泡断熱紙容器用紙基材、発泡断熱紙容器用シートおよび発泡断熱紙容器
Document Type and Number:
Japanese Patent JP6809445
Kind Code:
B2
Abstract:
To provide a paper base material for a foamed heat-insulating paper container which is excellent in a balance between a tensile strength and a compressive strength, and facilitates formation of a top curl part by having sufficiently small stiffness, and a sheet for a foamed heat-insulating paper container and a heat-insulation paper container using the same.SOLUTION: A paper base material for a foamed heat-insulating paper container includes a paper base material containing cellulose pulp as a main component and a water-soluble resin layer provided on at least one surface of the paper base material, in which a compressive strength in an MD direction measured according to a ring crush method defined by JIS P8126:2015 is 7.00kN/m or less, when a tensile strength (kN/m) in the MD direction is represented by T and the compressive strength (kN/m) is represented by C, T/C is 2.48 or more, and Taber stiffness in the MD direction measured according to the Taber stiffness test machine method defined by JIS P8125:2000 is 17.0 mN m or less.SELECTED DRAWING: Figure 4
