Laminates Triplex Alu / PET / CoPo: Multilayer solutions for insulation, EMI shielding and protection

Alu/PET/CoPo triplex laminates are multi-layer materials designed to meet the needs of industrial applications requiring an advanced combination of EMI shielding, electrical insulation and adhesion. Thanks to their three-layer structure, they offer superior performance to duplex laminates, particularly in demanding technical environments.

The combination of aluminium, PET and copolymer ensures optimal protection against electromagnetic interference, excellent dimensional stability and easy integration into industrial systems.

At ADDEV Materials, we support manufacturers in selecting and custom-processing technical laminates to optimise their performance and integration into applications.

Alu PET laminate

Structure and composition of Alu / PET / CoPo laminate

The laminate rests on an advanced technical architecture:

  • aluminium → electromagnetic shielding
  • PET → rigidity and stability
  • CoPo → Adhesive and functional interface

Each layer provides a specific function for optimised overall performance.

Triplex laminates are distinguished by their performance level:

  • duplex → 2-ply, standard solution
  • triplex → 3-ply, enhanced performance

The triplex is favoured for applications requiring multiple combined functions.

What is an Alu / PET / CoPo laminate?

A triplex laminate of Alu / PET / CoPo is a material made up of three complementary layers:

  • aluminium → EMI shielding and conductivity
  • PET → dimensional stability and insulation
  • copolymer → adhesion and integration

This structure allows for the achievement of:

  • optimised multi-layer performance
  • enhanced protection for systems
  • easier integration into assemblies

It is an ideal solution for complex industrial applications.
