PET Protective Film

Product Characteristic

Rainbow patterns on LCD or OLED screens after applying PE electronic protective film are caused by uneven film thickness creating optical interference. When thickness varies by more than ±3μm, light waves cancel and amplify at different wavelengths, producing visible color bands. Guangdayuan’s PE electronic protective film features precision coating technology with thickness tolerance below ±2μm, eliminating rainbow interference entirely.

Full Specification Parameters

Thickness range: 30μm to 80μm. Thickness tolerance: ±2μm (standard films: ±5μm). Width: up to 1600mm. Light transmittance: >92%. Haze: <3%. Adhesion: customizable from 1g/in to 50g/in for sensitive screens. Operating temperature: -10°C to 60°C. The film passes ISO9001 certification and is produced in a 16,000㎡ automated facility.
