Copper Grid PET Film (Transparent)

Copper Grid PET Film (Transparent)

 Transparent EMI shielding copper grid PET film 9400

PET film deposited with copper grid and protected with a nickel layer for EMI shielded windows & displays. High light transmission, excellent EMI shielding.

This transparent conductive Metal Mesh PET film is optical PET film deposited with copper grid and protected with a nickel layer. This film conducts better than our best 9900 series Transparent shielding foil and is only a fraction less transparent. This film has a conductive layer with a very fine etched mesh that is one with the transparent carrier.

Transparent conductive Metal Mesh PET film remains very high transparency, this film is extreme low resistance for high frequency EMI shielding application and is easy to apply. The copper mesh is almost invisible.

  • Film thickness : 75-100um
  • Transparency : >80%


Protective film + EMI shielding layer + optional adhesive (option A) + release layer. Due to the random structure none or almost no moire effect is visible when applied to an display.

NEW Micro Suction Silicone adhesive

For easy manual application of the foil we have developed a new Micro Suction Silicone adhesive. This adhesive has a number of advantages that make the film easy to position. We advise to use standard adhesive only for laminating machines or very very experienced people else use this new Micro Suction Silicone Adhesive

  • Reusable / Repositionable
  • Never attach permanently
  • Easy to apply by hand, less bubbly

Please note : Copper grid PET film with Micro Suction Silicone adhesive has a thickness of 230 micron / 0.23 mm.


Please note: top layer can be affected by acid for example from human skin. To protect the conductive layer, you can apply a transparent film or use the adhesive side on top.

Small optical defects are allowed in this product. If you require a product that has absolutely no optical defect then contact us for the “superior selected quality”. Please realize that due to the extreme caution needed for production of these products they can be several times more expensive.
