Document Type and Number:
WIPO Patent Application WO/2020/171031
Kind Code:
A1
Abstract:
[Problem] The problem that unevenness occurs in the foam layer and the insulating property deteriorates when lamination is carried out at high speed was clarified in a process for producing a sheet for a foam insulating paper container. Specifically, the problem addressed by the present invention is to provide a sheet for a foam insulating paper container that can be foamed without unevenness even when laminated at high speed. [Solution] The present inventors discovered that the problem addressed by the present invention can be solved by a method for producing a sheet for a foam insulating paper container in which a polyethylene resin is laminated on at least one side of a paper substrate, wherein the method for producing a sheet for a foam insulating paper container is characterized in that the lamination conditions are an air gap of 150 mm or greater and a take-off speed of 70 m/min or higher.
