Duplex laminates Cu / PET: conductivity and shielding solutions for electronic applications

Cu / PET laminates are multilayered materials designed to ensure a optimal electrical conductivity, high-performance EMI shielding, and excellent dimensional stability. Thanks to the combination of copper and PET film, they offer high performance for electronic and industrial applications requiring precision and reliability.

Particularly suited to demanding technical environments, these laminates make it possible to guarantee protection of systems against electromagnetic interference and electrical stress, while ensuring good mechanical stability.

At ADDEV Materials, we support manufacturers in the custom selection and transformation of technical laminates, in order to optimise their performance and integration into applications.

Laminated PET film

Structure and composition of Cu / PET laminate

The Cu/PET laminate is based on a high-performance technical structure:

  • Copper → Electrical conductivity and EMI shielding
  • PET → isolation and dimensional stability

This combination allows for a reliable and high-performing material.

Duplex laminates offer an excellent compromise between performance and simplicity:

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

The Cu/PET duplex is particularly suited for applications requiring electrical performance and simplicity.

What is a Cu/PET laminate?

A laminated duplex Cu/PET is a material composed of two layers:

  • a copper layer providing electrical conductivity and EMI shielding
  • a PET layer ensuring insulation and dimensional stability

This structure allows for the achievement of:

  • a Excellent electrical conductivity
  • un Effective electromagnetic interference shielding
  • a Good mechanical strength and stability

This is an ideal solution for electronic applications requiring precision and performance.
