Method for manufacturing packaging unit, involves fixing individual products to each other using shrinkable film, and applying shrinkable film with functional coating, which specifically changes physical properties of shrinkable film

摘要

The method involves combining individual products (1) to a product formation (2) and fixing to each other using a shrinkable film (3). The shrinkable film is applied with a functional coating (5,6,12), which specifically changes the physical properties of the shrinkable film in the coating area. The functional coating is directly applied as print coating, or indirectly applied to the film with interposition of an adhesive agent (10) or using a carrier (7), where a liquid or powdered thermoplastic polymer is applied as the carrier.
