Heat sealable HOSTAPHAN® polyester films

In contrast to many polyolefins, standard boPET films are not heat sealable. Though our co-extrusion technology, we can apply a sealable material to the film surface.
Our heat sealable HOSTAPHAN® seal to each other and to other polyester materials, for example A-PET and C-PET. They do not seal to polyolefins and are not peelable.

Besides our permanently sealing films, we also offer peelable HOSTAPHAN® films.

Typical applications for heat sealable HOSTAPHAN®-polyester films:
  • food packaging
  • metal lamination
  • roasting or cooking bags
  • lidding
  • tubes and bags
  • protective surfaces on glass fibre reinforced sheets
