BOPET Film
BOPET film is a high-transparency biaxially oriented polyester film made for applications where optical clarity matters as much as mechanical strength. It offers high light transmittance, low haze, and a flat, uniform surface — the combination that graphic arts, membrane switches, and label makers depend on for crisp imaging and clean lamination.
Key Specifications

FAQ
What is BOPET film?
BOPET is polyester (PET) film that has been stretched in two directions, giving it high clarity and mechanical strength. Read our guide to BOPET vs PET for the details.
What thicknesses are available?
25μm to 250μm, in eight grades listed above, with thickness, width and roll length customizable.
How clear is the film?
Light transmittance is 85–89% at 550 nm, with haze of 0.6–3.0% depending on gauge.
