Applications
Wuxi Wanfeng PE film for electronic screens is designed for critical cleanroom protection across LCD display manufacturing, touch panel assembly, and consumer electronic production lines.
- LCD & OLED Display Modules: Applied directly onto polariser plates, diffusion sheets, and display panel glass during module assembly, testing, and shipping to prevent static and dust.
- Touchscreen & Smart Device Covers: Protects glass cover lenses, capacitive touch sensors, and optical clear adhesive (OCA) stacks during CNC glass cutting, chemical strengthening, and screen bonding.
- Laptops, Tablets & Monitors: Shields notebook displays, commercial computer monitors, and interactive whiteboards during assembly line handling, testing, and final consumer retail packaging.
- Medical & Industrial Touch Displays: Provides clean surface protection for medical diagnostic screen covers, diagnostic instrument monitors, and industrial equipment HMIs during assembly and transit.
- Automotive In-Cabin Display Screens: Safeguards digital instrument clusters, central infotainment touchscreens, and heads-up display glass during automotive interior assembly.
Engineered for smooth integration into high-speed automated roll laminators or manual die-cut application, our optical films ensure bubble-free display protection.
Advantages
Partnering with Wuxi Wanfeng Protective Film Co., Ltd. for electronic display protective films delivers outstanding optical safety, cleanroom compliance, and product quality assurance.
- Class 1000 Cleanroom Manufacturing: Extruded and converted under strict cleanroom conditions to prevent dust particle contamination, gel spots, or fisheyes from damaging sensitive optical surfaces.
- Permanent Anti-Static Protection: Coated with an advanced ESD dissipative surface layer (10^8 - 10^10 ohms/sq) to eliminate static charge generation during film unwinding and screen peeling.
- Non-Outgassing Optical Clarity: High light transmittance (>92%) and ultra-low haze (<1.5%) allow clear visual inspection and touch function testing without peeling the protective layer.
- Ultra-Clean Residue-Free Peeling: Ultra-low tack adhesive formulation guarantees smooth, silent peeling without leaving glue lines, haze marks, or chemical outgassing on display polarisers.
- Direct OEM Precision Converting: Direct factory wholesale pricing, custom master roll widths, precision slitting down to narrow rolls, and custom die-cut sheet capabilities from our Wuxi facility.
