Copper foil polyester belt

Copper polyester tape, also known as copper-plastic composite tape, is composed of copper foil, PET film, and adhesive. It features low surface oxygen levels and excellent adhesion to various substrates, including metals and insulating materials. This tape is widely used in applications requiring electromagnetic shielding, grounding, and signal integrity.

Typical fields of application include communication equipment, computers, radios, and other electronic components. It is also commonly used as a shielding material for cables, FPC (Flexible Printed Circuit) boards, and soft circuit boards.

The copper foil used—often rolled or electrolytic copper foil—offers high tensile strength, excellent flexibility, good ductility, outstanding conductivity, efficient heat dissipation, and a smooth, glossy surface. These properties make copper polyester tape an essential material in a range of advanced electronic and cable manufacturing processes.
