Copper metallized PP film
Copper vapor-deposited onto film in a vacuum. High dielectric, excellent insulation, heat resistance.

Polypropylene (PP)
Semi-crystalline thermoplastic, strong impact resistance, robust mechanical properties, and resistance to various organic solvents and acid-base corrosion



Vacuum metallization includes vacuum deposition, sputtering, ion plating and other methods to form various metallic and non-metallic thin films on the surface of products in a vacuum environment to achieve the effect of electroplating.

In a vacuum, the coating material is evaporated or sputtered and deposited onto the substrate to form a thin film. Since there are no air molecules to interfere, the coating material can travel in straight lines and form highly uniform layers.

Copper/PET shielding tapes is primarily used in various fields, such as extremely fine coaxial wires, low-loss antennas (computers), solar cell wires, etc.

EMI solutions include three main approaches: electromagnetic interference shielding, printed circuit board grounding, and electromagnetic interference absorption.

  • Electromagnetic Interference Shielding involves blocking electromagnetic noise and attenuating cable-collected noise. It uses high-reflectance materials (usually low-resistance metals) to encase or seal openings in target devices for EMI and EMS solutions.
  • Printed Circuit Board (PCB) Grounding refers to grounding electronic equipment electrically to prevent electric shock, treating the Earth as a massive conductor at zero electric potential. Two grounding methods are employed: frame grounding and signal grounding on PCBs.
  • Electromagnetic Interference Absorption (EMI Absorption) utilizes magnetic loss, dielectric loss, and conduction loss to convert radio wave energy into thermal energy. EMI absorbers have a wide range of applications.
