Triplex laminates Alu / PET / Alu: EMI shielding and multilayer protection solutions

Alu/PET/Alu triplex laminates are multi-layer materials designed to provide enhanced protection against electromagnetic interference (EMI), an excellent environmental barrier and high mechanical stability. Thanks to their three-layer structure incorporating two aluminium faces, they ensure maximum performance in demanding industrial environments.

Particularly suited to applications requiring double-sided shielding and advanced protection, these laminates ensure the reliability of electronic and electrical systems in the face of external stresses.

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 / Alu laminate

The laminate rests on a high-performance symmetrical architecture:

  • aluminium / PET / aluminium
  • double conductive layer
  • heart baffle

This structure ensures consistent, enhanced performance.

Triplex laminates offer superior performance:

  • single layer
  • triplex → double functionality + reinforced protection

The Alu / PET / Alu laminate is particularly suited to critical applications.

What is a triplex laminate Alu / PET / Alu?

A laminated triplex Alu / PET / Alu is a material composed of three layers:

  • aluminium (side 1) → EMI shielding and conductivity
  • PET → dimensional stability and insulation
  • aluminium (side 2) → reinforced shielding and additional barrier

This structure allows for the achievement of:

  • double-sided electromagnetic shielding
  • enhanced protection against external threats
  • excellent mechanical stability

This is an ideal solution for applications requiring a high level of protection.

Rolled Aluminium / PET / Aluminium vs. Other Materials: What's the Difference?

The triplex laminate Alu / PET / Alu is positioned as a maximum protection solution.

Triplex laminate vs aluminium / PET duplex

  • triplex → double EMI shielding
  • single-sided

Laminated Aluminium / PET / Aluminium vs Copper / PET

  • aluminium → lighter solution
  • copper → better conductivity

Laminated Aluminium / PET / Aluminium vs. Technical Films

  • laminated → advanced multilayered solution
  • film → simple solution

In a nutshell

  • Choose a triple-layer aluminium/PET/aluminium laminate for maximum protection, enhanced EMI shielding and an effective barrier
  • Prioritise a duplex for less critical needs.
