Copper Coated Film

DUNMORE - Copper Coated Film

DUNMORE Corporation is an industry leader in producing highly technical copper coated films. DUNMORE's expertise in metallized copper film and other copper substrates stretches across a broad spectrum of uses and industries. Whether you are looking for conductive film or EMI shielding material, DUNMORE can provide you with the right solution to meet your project requirements.

Depending on your needs, we can provide you with a copper substrate that is unprotected or with a proprietary non-corrosive coating to protect copper thin film from oxidation. DUNMORE's standard copper film, which uses a 25 micron PET film has a conductivity range of 0.4 - 0.8 ohms per square.

Copper Substrates

Our copper metallizing capabilities can open up new design possibilities for your project by providing new alternatives to traditional copper foil laminates. Copper film has weight advantages and gives you greater processing flexibility as you design and manufacture your next generation product. In order to meet your strict weight requirements, DUNMORE can produce a conductive thin film materials that is 6 microns thick. DUNMORE also has the capabilities to copper metalize a variety of other substrates. Along with our standard copper metallized PET film, DUNMORE can work with you to copper metallize the following types of base materials:

  • Copper coated polyimide film
  • PET Film
  • PEEK Film
  • Woven Fabric & Non-woven Fabric

Copper Substrate Applications

Copper coated film and copper conductive film can be used for a variety of applications. Typical applications for DUNMORE's copper thin films include:

  • Decorative
  • Labels & Graphics
  • Electronic shielding
    • EMI shielding material
    • RF shielding material
  • Flexible electronics
    • Sensors / RFID antenna
  • Thermal Management
  • Seed layer for electroplating
  • Tape backing film

Copper Film Performance

Dunmore tested our copper coated film against a standard Al coated film on a 92 gauge PET film. Along with having superior infrared reflectance compared to Al film, our copper film has the following attributes:
