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 JP7040587
Kind Code:
B2
Abstract:
To provide a foamed heat-insulation paper container which reduces variations in a place of a permeation amount of water vapor generated from a paper base material, uniformly foams a thermoplastic resin layer, and thereby is excellent in heat insulation and appearance of the surface, and to provide a paper base material for foamed heat-insulation paper container and a sheet for foamed heat-insulation paper container used in the production.SOLUTION: A paper base material 3 for foamed heat-insulation paper container has an ethylene-modified polyvinyl alcohol layer 2 on at least one surface of a paper base material 1. A sheet for foamed heat-insulation paper container has an ethylene-modified polyvinyl alcohol layer between a paper base material and a thermoplastic resin layer. A foamed heat-insulation paper container uses foamed heat-insulation paper in at least one of a body member and a bottom plate member, and the foamed heat-insulation paper has a foamed resin layer formed from a thermoplastic resin on at least one surface of a paper base material, and has an ethylene-modified polyvinyl alcohol layer between the paper base material and the foamed resin layer.SELECTED DRAWING: Figure 1
