Gridliner (PET - reinforced PET grille - PET): reinforced technical laminate for stability and protection

Gridliner laminates (PET – PET grid – PET) are multi-layer materials designed to offer high dimensional stability, mechanical reinforcement, and excellent durability. Thanks to the integration of a PET grid between two polyester layers, they allow for Rigid and homogenous structure suitable for demanding industrial applications. 

These laminates are particularly used in environments requiring a High precision, enhanced mechanical strength, and structural stability, notably in the energy, electronics, and industrial sectors. 

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.

Structure and composition of Gridliner laminate

The laminate rests on a reinforced architecture: 

  • PET / PET grille / PET 
  • Structuring heart 
  • double stabilising layer  

This structure guarantees excellent mechanical strength and homogeneous stability. 

The Gridliner is distinguished by its structural reinforcement: 

  • rigidité et stabilité élevées 
  • Non-woven → Absorption 
  • cellulose → isolation 
  • aluminium → shielding  

It is preferred for applications requiring a reinforced structure. 

What is a Gridliner (PET – PET grid – PET)

A Gridliner is a three-ply laminate composed of three layers: 

  • PET (face 1) → dimensional stability and protection  
  • PET grille Structural reinforcement and mechanical strength  
  • PET (ansigt 2) → Stability and additional protection  

This structure allows for the achievement of: 

  • Excellent structural rigidity  
  • Increased resistance to mechanical stress  
  • high dimensional stability  

This is an ideal solution for applications requiring precision and mechanical strength.

Gridliner vs other materials: What's the difference?

The Gridliner positions itself as a reinforced structural solution. 

Gridliner vs. spunbond non-woven PET 

  • rigidité et structure 
  • non-woven → flexibility and absorption  

Gridliner vs PET / Cellulose 

  • gridliner → mechanical strength 
  • cellulose → electrical insulation  

Gridliner vs PET film 

  • reinforced structure 
  • film → simple solution  

 In a nutshell 

  • choose one Gridliner for a dimensional stability, structural reinforcement and high precision 
  • Prioritise other laminates according to your specific constraints.
