In contrast to cast films, calendered films are pressed by rollers during production. In addition, around 20 to 25 % plasticiser is added to them. "Monomer" refers to short-chain, highly volatile plasticisers, "polymer" to longer-chain plasticisers.
Monomer calendered films
Typical applications: Interior, trade fair construction, shop fitting, short-term advertising campaigns.
Advantages:
Disadvantages
- Only suitable for flat or slightly curved surfaces
- Short shelf life (up to 4 years)
- Environmental influences (heat, UV radiation, chemicals) cause the film to become brittle
- Memory effect: calendered films have a tendency to shrink and return to their original shape.
Polymer calendered films
Typical applications: Interior and exterior, vehicle labelling and part wrapping
Advantages
- Relatively inexpensive
- Similar properties to monomer calendered films, but more durable
- Polymeric plasticisers mean the film retains its shape for longer and is less prone to shrinkage
Disadvantages
- Only suitable for flat or slightly curved surfaces
- Average durability (up to 7 years)
- Environmental influences (heat, UV radiation, chemicals) cause the film to become brittle
- Memory effect: Calendered films have a tendency to shrink and return to their original shape.
Moulded films
Typical application: Vehicle wrapping
Advantages
- Very easy to mould and stretch, ideal for 3D bonding
- Can be removed and repositioned several times during application
- High resistance to chemical reactions and UV radiation
- Long durability (up to 10 years)
Disadvantages
Tip: Production fluctuations
Always use films from the same batch for your orders to avoid colour variations.
Tip: Pay attention to shelf life
Films should not be used beyond their service life, as the onset of decomposition makes them difficult to remove and can damage the paintwork. Horizontally bonded films wear out more quickly due to direct sunlight.
