50μm BOPET Film
If there is one gauge that does it all in the high-transparency range, it is 50μm. This is the everyday workhorse — thick enough to stay flat and handle well on press, thin enough to keep material costs sensible. With 86.5% light transmittance and 0.9% haze, it keeps printed graphics crisp and laminated surfaces clean, making it a dependable choice for labels, graphic arts, and membrane switch production.

FAQ
Why is 50μm called the all-round gauge?
It is thick enough to stay flat and handle well on press, and thin enough to keep material costs sensible.
What do 86.5% transmittance and 0.9% 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.
