188μm BOPET Film
This is one of the thickest grades in the BOPET range, and it brings toughness rather than sparkle. At 188μm, elongation at break reaches 190% MD, so the film stretches and absorbs stress instead of tearing — a useful trait when it has to survive die-cutting, punching, or repeated mechanical handling. Light transmittance sits at 85.1% with 2.0% haze, giving a clean but not optical-grade finish.

FAQ
What does 190% MD elongation mean?
It is how far the film stretches in the machine direction before it breaks. A higher value means the film absorbs stress instead of tearing, which helps in die-cutting, punching and repeated handling.
Is it as clear as thinner grades?
Light transmittance is 85.1% with 2.0% haze, a clean but not optical-grade finish. The priority at this gauge is toughness.
What is the thermal rating?
UL746B RTI of 105°C electrical and 105°C mechanical.
