250μm BOPET Film
This is the thickest grade in the BOPET range — a structural-weight film rather than a thin optical layer. At 250μm it holds its shape under load, resists deformation through repeated handling, and still keeps 190% MD elongation, so it bends instead of cracking. Light transmittance is 84.0% with 3.0% haze, which is normal for a film at this gauge; the priority here is body and durability, not maximum clarity.

FAQ
Why choose 250μm?
When you need body and durability rather than maximum clarity. It holds its shape under load and bends instead of cracking.
Why is the haze higher than thinner grades?
Haze of 3.0% and 84.0% transmittance are normal for a film at this gauge.
What is it used for?
As a structural base film, for die-cut parts, membrane switches, labels, printing and lamination.
