Description
Our diffuser films are designed to create smooth, even light — from opal films that eliminate LED hotspots to translucent films that offer high light transmission.
Each film combines a matte surface for scratch resistance with a fine matte side for easy printing, giving you both protection and flexibility.
We can supply the films die-cut to your drawings or in roll form for automated production. They offer excellent dimensional stability and clean, precise edges after cutting.
Typical applications include:
- Consumer electronics and smart devices
- Edge-lit and backlit LED luminaires
- Advertising lightboxes and displays
- Instrumentation panels and graphic overlays
- Automotive interior lighting

Packing
1. Standard Packing Options
- Rolls:
Optical films are rolled on anti-static paper or plastic cores (6″) and tightly wound with protective liners to prevent telescoping and dust contamination.
Each roll is packed in a reinforced carton or crate for safe shipment. - Final Cut / Sheet Sizes:
Cut-to-size films are individually interleaved with protective films or kraft paper and stacked flat to prevent scratches, bending, or warping during transit.
2. Surface & Edge Protection
- Edge & Corner Protection:
Roll edges and sheet corners are secured with foam guards or plastic protectors to prevent damage from handling or vibration during shipping.
3. Palletization & Securing
- Rolls and flat stacks are palletized or crated.
- Straps, shrink wrap, and corner reinforcements keep materials stable throughout transit.
- Maximum pallet load: 800 kilograms or as specified per film thickness to prevent compression or deformation.
4. Shipping & Storage Recommendations
- Flat Storage:
Store cut-size films on a flat, clean surface, avoiding uneven pressure. - Roll Storage:
Store rolls upright on cores or suspended horizontally to prevent deformation and edge curling. - Environmental Conditions:
Maintain room temperature (20–25°C) and humidity (40–60%). Avoid direct sunlight or extreme temperature changes. - Handling:
Always wear lint-free gloves when removing protective liners to prevent contamination and fingerprints.
