Opacity in PVC milky white film can hinder quality control, but Guangdayuan's innovative additive technology balances light transmission with protective opaqueness. Their film combines functional opacification with 80 - 85% visible light transmittance, verified by UV - vis spectroscopy.
The secret lies in Guangdayuan's proprietary surface treatment of TiO₂ particles, coated with silane coupling agents to prevent agglomeration. This improves dispersion in the PVC matrix, reducing light scattering. The extrusion process uses a 30:1 L/D ratio screw for uniform mixing, achieving a haze value <5%—significantly clearer than standard milky films (haze >15%).
Key applications include:
- Optical components: Protecting lenses and prisms while allowing alignment checks
- Pharmaceuticals: Transparent blister packaging for pill visibility
- Solar panels: Backsheet protection with minimal light loss
- Food industry: Frosted packaging for aesthetic appeal with product visibility
The film meets FDA 21 CFR 175.300 for food contact, and its anti - static variant (surface resistance 10⁶ - 10⁹Ω) is ideal for electronics. Guangdayuan's cooperation with Harbin Institute of Technology enables continuous R&D, such as incorporating nano - SiO₂ to further enhance clarity without compromising impact resistance (IZOD >50J/m).
