METAL MESH FILM



    Metal Mesh Copper Grid PET EMI Shielding Film

   Same as ITO PET film, Metal Mesh PET Film is an excellent transparent EMI shielding film for LCD,precise instruments,military,hospital scanning house etc.

    The difference point between ITO film and Metal mesh film is the conductive surface. ITO PET film is 100% ITO deposited, while Metal mesh film is a very fine micron mesh deposited on PET substrate,but metal mesh is more durable and can achieve <0.5 ohm/sq with 80% VLT applicable for area of high EMI shielding requirement.

    Metal mesh(also called copper grid) film, surface is protected with a very thin layer conductive nickel to prevent copper grid oxidation, the mesh angle is designed standard 45 degree.  To apply on LCD,better to adjust to best angle to avoid moire 
 image distortion.
   Optical adhesive can be backed upon request.
