PE Plastic Protective Film Light Transmittance
The light transmittance of PE Plastic Protective Film varies significantly depending on its type, thickness, and manufacturing process.
Standard Transmittance Ranges
| Film Type | Thickness | Light Transmittance | Typical Applications |
|---|---|---|---|
| Standard PE Film | 10-100 microns | 50-85% | General surface protection |
| Thin PE Film | 10-30 microns | 75-85% | Glass, glossy plastics |
| Thick PE Film | 50-100 microns | 50-70% | Heavy-duty protection |
| High-Clarity PE | 20-50 microns | 90%+ | Electronics, displays |
- High-transparency films (>90% transmittance) approach optical-grade clarity for applications like smartphone screens and LCD panels
- Additives impact: UV stabilizers, anti-static agents, or anti-scratch coatings may reduce transmittance by 5-15%
- Haze comparison: PE films typically have more light diffusion than PET films, which offer superior optical clarity
For light-sensitive applications (display protection, solar panels), always review manufacturer specifications and test samples under intended use conditions to verify actual transmittance and haze levels.
