Document Type and Number:
WIPO Patent Application WO/2024/038797
Kind Code:
A1
Abstract:
A method for manufacturing a laminate having a paper base material layer, and a resin layer that contains a polyhydroxyalkanoate resin and that is formed on at least one surface of the paper base material layer. The method includes: a step for forming, on a film, a polyhydroxyalkanoate resin in which the highest melting peak temperature in differential scanning calorimetry is 130°C or above and the total crystal melting enthalpy calculated from all melting peaks is in the range of 30-65 J/g (step i); a step for applying an adhesive on one surface of the film and forming an adhesive layer (step ii); and a step for laminating a paper base material layer on the adhesive layer surface (step iii).
