Pressiza 73

Pressiza 73 is a 2 mil (50 μ) polyamide film with a high temperature permanent pressure sensitive acrylic adhesive and a high-opacity matte white top layer specifically designed for thermal transfer printing.


  • 2 mil (50µ) polyimide film with a high-temperature permanent pressure sensitive acrylic adhesive and a high opacity, matte white topcoat specifically designed for thermal transfer printing.
  • Preheating the labeled product can further enhance print permanence in the case of extreme solvent and/or abrasion exposure, although this is not typically required for board processing applications.
  • The surface that you want to label should be clean, dry and free of any surface contamination, such as dust, oil or rust. Isopropyl alcohol would be a recommend solvent to clean the surface.
  • When you apply the label, you must use firm pressure to increase the physical contact of the adhesive with the surface of the product.
  • Pressure sensitive adhesives will provide stronger bonds to a warm surface, as compared to a colder surface. The adhesive will ‘flow’ more readily, increasing the surface area and increasing the adhesion peel strength.
  • Topcoat & print should not be contacted while exposed to elevated temperature.

Suggested applications: 

  • PCB identification.
  • Electronic components.
  • Hand held devices.
  • Metals processing applications: slabs, coils, rolls.
  • IC labeling for work in process, permanent ID & warranty labeling.
  • Product ID, asset tracking.
  • Anywhere a label will be exposed to extreme temperatures.
