Dedicated Polyester Film Stabilising Capability
HIFI’s stabilising equipment is designed to improve polyester film dimensional stability by applying a controlled thermal process before the material enters the customer’s production route.
This is valuable for processes involving heat, tension, printing, curing or lamination, where uncontrolled shrinkage can affect registration, alignment, flatness and final component quality.
The stabilising route should be selected based on film grade, thickness, process temperature, residence time and the customer’s required dimensional stability target.

Frequently asked questions
Heat-Stabilised Polyester Film
Heat-stabilised polyester film is PET film that has been thermally processed to improve dimensional stability and reduce shrinkage during later manufacturing steps.
It helps maintain registration, flatness and dimensional accuracy in processes involving heat, printing, curing, lamination or assembly.
HIFI can support film thicknesses from 36 µm to 500 µm, subject to material and process review.
Thermal stabilisation typically targets dimensional change around 0.1%, but performance depends on film, process conditions and customer validation.
Yes. Stabilised film can be converted into customer reel formats where required.
