Black Polyester Film
Black polyester film is an opaque, light-blocking PET material engineered for applications that require complete concealment and UV protection. Unlike standard transparent films, it is heavily pigmented or carbon-coated to achieve a light transmittance of less than 1%, ensuring zero light bleed in electronic displays and sensitive component packaging. It retains the excellent mechanical strength and dimensional stability of standard PET, making it highly reliable for precision die-cutting and high-temperature masking.

FAQ
How much light does the film block?
Light transmittance is less than 1%, so the film is opaque and prevents light bleed.
Is the surface matte or glossy?
Either. The surface finish is customizable.
What thicknesses are available?
25μm to 250μm, with custom thickness, width and roll length.
Can I get samples?
