  • dimensional stability
  • resistance to heat and cold
  • excellent suitability for printing, metallisation and lamination
  • good barrier to aromas, gases and water vapour
  • resistance to common organic solvents, oils, greases and many inorganic substances
  • resistant to mould and bacteria
  • freedom from plasticisers, odours and flavours
  • base material suitable for food contact (details on request)
  • excellent electrical insulation
  • available with a variety of physical properties and surfaces
Typical applications for HOSTAPHAN® polyester films:
  • packaging
  • metal lamination
  • furniture surfaces
  • thermal transfer printing
  • medical applications
  • security applications
  • carbon composites
  • others

STORAGE CONDITIONS

The polyester film HOSTAPHAN® is largely unaffected by climatic influences.

We recommend that the film is kept in the original packaging until used.
A dry dust-free storage room with an ambient temperature below 30°C is of advantage.

Avoid storing the film outdoors for any significant period of time where it will be exposed to harmful influences such as humidity or direct sunlight. The film should be transferred, in the transport packaging, to the processing area or a room with a similar climate at least 24 hours before processing.

We recommend removing the film from the original packaging immediately before processing. After removal, transporting the film roll by means of a steel bar through the core will prevent deformation or damage to the outer layers.

Short-term storage in polystyrene throughs is also an option with HOSTAPHAN® films with a thickness equal or greater than 36 µm. We know of no restriction to the shelf-life of HOSTAPHAN®. Nevertheless, we recommend that the film is processed within a year of delivery.
