König Film Centre offers the following high-quality products for the application area of input systems:

  • Folex ® Polyester Folien (vom Hersteller Folex ®).
  • Reflex LT® Polyester Folie (vom Hersteller Transcontinental ®).

Through our long experience as a polyester film supplier, we have built up a great deal of know-how. We would be pleased to advise you in finding the right quality polyester film for your application. We will send you technical data sheets or samples for the creation of first prototypes or for first tests. Contact us, we look forward to your enquiry!


Properties of polyester films (PET films) for input systems

Biaxially oriented polyester films are characterised by excellent chemical, mechanical and thermal stability. This special film can therefore be used for a wide range of industrial applications. PET films can be printed (for example with UV ink), are scratch and tear resistant and offer good UV resistance.

Is polyester film scratch resistant?

Some products in our range have a scratch-resistant coating on the front. The scratch resistance makes these films (Folex GO HC NQ and Reflex LT) a durable and long-lasting solution.

The scratch resistant polyester film otherwise has the normal properties of polyester and has no disadvantages.

Is scratch-resistant polyester film printable?

Our customers often ask us whether PET (polyester) film can be printed. Due to a special printing pre-treatment (coating), polyester films for input systems are ideal and constantly printable. The specially developed coatings make the polyester film printable.

The PET polyester film is ideally suited for screen printing. In addition, film printing is also possible in digital printing and with UV-curing inks as well as colour lacquers, silver-conductive and dielectric inks. For more information on the printable polyester films, the coating and whether it can be printed on both sides, please contact us!

Is polyester film tear resistant?

Polyester films have increased tensile strength and dimensional stability and are very stable. Polyester (PET) plastic is less prone to moisture absorption and low thermal expansion and is tear resistant.

UV resistance

Polyester films (PET films) of the Folex brand have a high UV resistance and are suitable for outdoor use. This property, the possibility of printing and their scratch resistance make polyester films an ideal material for, for example, signs, stickers and self-adhesive labels.



PET films (polyester films) can be processed in various ways. They can be cut, die-cut, bent, printed, heat-sealed and self-adhesive. PET film does not become brittle with ageing as it does not contain any plasticisers. Deformation under heat is only possible to a limited extent with polyester films. No special accessories are required for processing special polyester films.



Our special polyester films are designed to meet the requirements of industrial and electronic applications. They are used in the automotive, electrical or electronics, card, pharmaceutical, packaging or furniture industries. Possible applications are:

  • Membrane keypads
  • Input systems
  • Membrane tactile switches
  • Flexible conductors
  • Signs
  • Labels
  • Stickers/self-adhesive labels
  • Industrial moulded and die-cut parts
  • Decorative cover foils
  • Displays
  • Various industrial applications
  • Outdoor use

A high level of quality is required for these applications.


Thicknesses and surfaces

As a polyester film (PET film) supplier, we carry a wide range of products in various thicknesses. We offer printable polyester film for membrane switches in thicknesses from 130 µm to 250 µm. On request we can supply films in thinner and thicker thicknesses. We offer our polyester films (polyethylene terephthalate film) in rolls or in blanks in the desired format.

Our printable film differs in terms of surface: 

  • Folex GO HC NQ - clear polished, scratch resistant        .
    • Folex GO MA - one side matt                                       .
  • Reflex LT - one side matt, scratch resistant           .
  • Folex GO FT NQ - one side finely textured                       .

If you would like to convince yourself of the quality of the material, we would be happy to send you a sample and data sheets from the manufacturers of our special polyester films.

If you have any questions or requests, or if you are looking for specific plastics, specific surfaces, data sheets, cut formats or applications, please do not hesitate to contact us.
