Process and Protective Films for Electronic Devices
Surface‑Protection Solutions for Electronic Manufacturing
Electronic devices demand flawless cosmetic and optical surfaces through precision manufacturing, assembly and global logistics. COFIFILM protective films preserve displays, housings and coated components with stable adhesion, clear inspection and clean removal.
Electronic Device Considerations
Why Electronics Need Precision Surface Protection
Electronic devices combine delicate optical surfaces, functional coatings and high-throughput assembly. Generic films can haze displays, damage finishes or leave residue behind.
Optical & Cosmetic Surface Sensitivity
Displays, camera windows and glossy housings reveal every mark. Protection must preserve transparency, color and surface uniformity without haze or ghosting.
Functional Coating Compatibility
Anti-glare, anti-fingerprint and hard-coat finishes can react to unsuitable adhesives. Films need precisely calibrated tack and clean release.
High-Volume Handling Risks
Automated assembly, stacking and global logistics expose parts to abrasion, dust and impact. Protective films must stay secure yet remove quickly at final inspection.
Electronic Device Solutions
Flawless Protection for Every Device Surface.
Built for Precision Electronics
Protects displays, housings, bezels and precision components through machining, assembly and repeated handling without compromising fit or finish.
Stable Adhesion, Gentle Release
Balanced adhesive systems stay secure on smooth plastics, coated metals and glass while peeling away cleanly when inspection or assembly is complete.
Clarity for Inline Inspection
High-transparency grades support automated and visual quality checks, keeping screens and cosmetic surfaces clear, clean and residue-free.
Display & Cover Glass Protection
Crystal-Clear Protection for Screens and Camera Windows
Display glass and optical windows must remain flawless through cutting, coating, assembly and transit. COFIFILM films preserve clarity without residue.
Optical Clarity Without Haze: High-transparency films protect display cover glass, camera windows and touch panels from scratches, dust and fingerprints without reducing visual clarity.
Safe for Anti-Glare & Hard Coats: Chemically balanced adhesives protect AR, anti-glare and hard-coated surfaces without stripping microscopic functional layers during removal.
Clean Removal Before Final Assembly: Films peel smoothly after storage and handling, leaving no haze, ghosting or adhesive transfer on critical optical surfaces.
Available models:
Models: PT-ELEC-AR-CLEAR
Device Housing Protection
Clean Protection for Premium Housings and Bezels
Electronic housings combine cosmetic finishes with complex profiles. Our films maintain a secure bond through handling and remove cleanly before final delivery.
Protection for Glossy & Painted Housings: Shields piano-black, anodized, painted and polished housings from scratches, scuffs and fingerprints during production and installation.
Reliable Grip on Complex Profiles: Flexible carriers conform to curved covers, recessed edges and textured surfaces without wrinkling, lifting or delaminating.
Zero-Residue Peel After Storage: Stable adhesive chemistry removes cleanly after stacking and long-distance transport, preserving the original color and gloss of every housing.
Available models:
Models: PT-ELEC-GLOSS
Precision Assembly & Transit
Protection From Production Line to Customer
High-value electronic components face repeated handling, stacking and shipping. Reliable protective films preserve every cosmetic and optical surface until handover.
Abrasion and Impact Resistance: Durable carriers protect finished components from fixture contact, stacking friction and dropped tools on automated assembly lines.
Stable Performance Across Climate Cycles: Engineered adhesion remains reliable through temperature and humidity changes from factory staging to global shipment.
Fast Uncovering at Final Inspection: Low-residue films peel away quickly before quality checks, packaging or customer delivery, keeping throughput high and surfaces pristine.
Available models:
Models: PT-ELEC-PEEL
