Definitions

  • the present invention relates to a packaging bag with a spout and a method for manufacturing a packaging bag with a spout.
  • the present application claims priority based on Japanese Patent Application No. 2020-182338 filed in Japan on October 30, 2020, the contents of which are incorporated herein by reference.
  • Standing pouches are widely used as refill containers for shampoo and conditioner.
  • the pouch body of a standing pouch is composed of a laminated film.
