Tinned Cu-PET foil is wildly used for the electromagnetic shielding and electrical cables and wires signal shielding.

The Tinned Cu-PET foil is made of copper foil and PET film by scientifically processing with width in 5mm-350mm, thickness 0.035mm. We also can make different standard according to customers’ special requirements. The tinned copper foil is characterized with excellent shielding function and high conductivity. They are used for automotive wire and high-frequency interference shielding materials.
