Document Type and Number:
WIPO Patent Application WO/2021/054455
Kind Code:
A1
Abstract:
The present invention is a method for remanufacturing an article transporting container sheet, the method including: a first heating step for heating, at a first temperature, the article transporting container sheet having a first accommodation shape capable of accommodating a first article; and a flattening step for forming, into a flat shape, the first accommodation shape of the sheet that has the first accommodation shape and has been subjected to heating at the first temperature. The sheet contains a macromolecule satisfying conditions (1) and (2) below. The first temperature is between the melting point Tm of the macromolecule and 280°C, inclusive. (1) The limiting viscosity [η] measured in a decalin solution at 135°C is between 4.0 dL/g and 35.0 dL/g, inclusive. (2) The melting point Tm is between 120°C and 140°C, inclusive.
