Document Type and Number:
WIPO Patent Application WO/2020/171032
Kind Code:
A1
Abstract:
[Problem] An examination of microwave oven-resistant sheets used in foamed thermal insulation paper containers revealed that blisters occur in the containers in the course of microwave oven treatment. That is to say, the present invention addresses the problem of providing a sheet to be used in a foamed thermal insulation paper container such that no blisters occur during microwave oven treatment. [Solution] The present inventors have discovered that the problem addressed by the present invention can be solved by a method for producing a sheet to be used in a foamed thermal insulation paper container, the method being characterized by an air gap of 150 mm or larger, a draw speed of 65 m/minute or slower, and a polyethylene resin density of 0.923 to 0.930 kg/m3.
