125μm BOPET Film
At 125μm, this BOPET film leans toward stability over pure optics. Thermal shrinkage drops to 0.9% MD, which means the film holds its dimensions better through heat and repeated processing — useful when registration matters or when the film will be laminated and re-handled more than once. Light transmittance is 85.6% with 1.6% haze, giving a clean, even appearance rather than a razor-sharp optical finish.

FAQ
What does 0.9% MD thermal shrinkage mean?
It is how much the film shrinks in the machine direction after 30 minutes at 150°C. A lower number means better dimensional stability through heat and repeated processing.
When should I choose 125μm?
When registration matters, or when the film will be laminated and re-handled more than once.
What is the thermal rating?
UL746B RTI of 105°C electrical and 105°C mechanical.
