38μm BOPET Film
The 38μm grade hits a practical middle note in the high-transparency range. It is thin enough to keep weight and cost down, yet carries enough body to run cleanly through printing and lamination lines. With 86.9% light transmittance and 0.6% haze, it keeps graphics sharp and colors true, making it a reliable workhorse for graphic arts, labels, and membrane switch construction.

FAQ
Why choose 38μm?
It is thin enough to keep weight and cost down, yet carries enough body to run cleanly through printing and lamination lines.
What do 86.9% transmittance and 0.6% haze mean?
Light transmittance is the share of light that passes through the film, and haze is how cloudy it looks. A higher transmittance and a lower haze both mean a clearer film.
What is the thermal rating?
UL746B RTI of 105°C electrical and 105°C mechanical.
