Flexible Packaging

Flexible laminates for packaging applications are multi layer materials of paper, plastics films and metal foils. Depending on the requirements a broad range of 1C or 2C solvent free and solvent borne PU laminating adhesives are in use. Low molecular weight DYNACOLL® polyester polyols allow the formulation of high quality adhesives for reduced weight laminates. High molecular weight DYNACOLL® S copolyesters are recommended for primer applications and extrudable systems.
