Abstract (en)
[origin: JP2022020609A] To provide a method of producing a packaging material having a functional layer on a substrate using a casting process to coat the substrate.SOLUTION: A manufacture of a packaging material having at least one functional layer in which a water-based multilayer curtain is formed, the curtain to a substrate is applied, the outer layer of the curtain which comes into contact with air during casting includes surface activation additive, and the difference in a surface tension between the two outer layers of the curtain and the adjacent one or plurality of inner layers is at least 5 mN/m is described.SELECTED DRAWING: None
