Electromagnetic wave shielding film is also called EMI (Electromagnetic Interference) protective film or absorbing material.

Our EMI shielding film is mainly used to reduce or eliminate electromagnetic interference on the internal circuit of the product by pressing on the film after the copper material is etched and processed.


Mainly used in 5G communications, automotive electronics, consumer electronics products (smart phones, tablet computers, touch panels, digital cameras, LCD TVs, etc.) and line electromagnetic shielding of military products.

Excellent Physical Properties


High and low temperature test

It can reach -85°C to +85°C, and can be used normally in extreme environments;

Environmental test: The test product functions normally at -80°C, 100°C (boiling water), and -235°C.


Cyclic bend test

Bending degree: from 0~90~180 degrees (cyclic bending), bending diameter: 4mm, 8mm.


Loop folding test

When the bending diameter is less than or equal to 4mm, the bending angle can be used normally under cyclic folding from 20 degrees to 180 degrees.
