9400 series Transparent EMI shielding copper grid PET film

PET film deposited with copper grid and protected with a nickel layer

Holland Shielding Systems BV is specialized in manufacturing transparent EMI shielding foils and films.

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%
  • Resistance          :    

Structure

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