A packaging container is such that a laminate (45) features a film-shaped substrate (44) bonded to a hot-sealing layer (38) via a contact adhesive layer (36) - for easy opening and re-closing the container - arranged between an adhesive layer (34) of permanent adhesive and a hot-sealing layer (38) and is bonded to itself via a sealing seam or to another film to form a pouch or, as lid, bonded to the edge of a pouch. For the production of the laminate (48), the film-type substrate (44) is coated - via liquid-film coating using the curtain coating or slide-coating method - with a multi-layer liquid film comprising at least an adhesive layer (34), the contact adhesive layer (36) and the cohesively rupturing hot-sealing layer (36).
