For most applications we recommend the use of 2K epoxy or 2K polyurethane adhesive systems.
The best bond strength values are achieved via surface pre-treatments of the film surfaces to be bonded:

Bond strength may be optimized in some films by grinding the surface. We also offer some types of films with coated fleece because it improves bonding with the adhesive system.

Please note that in applications where bonding is on the printed side of a film (i.e. in transparent films with back-printing), bonding between the printing ink and the film is crucial for strength of the bonding (see also the section on printing). In individual cases, the suitability of the adhesive system needs to be discussed with the relevant manufacturer.
