Struggling with PVC milky white film that obscures protected items? Shenzhen Guangdayuan's advanced formulation technology enhances clarity while maintaining essential opacification for optimal protection.
Guangdayuan's PVC milky white film incorporates nano - grade TiO₂ particles (diameter <50nm), evenly dispersed via a twin - screw extruder to achieve 85% light transmittance—20% higher than conventional products. The company's three - layer co - extrusion process (skin - core - skin) features a clarified core layer with metallocene - catalyzed PE, reducing light scattering. Surface roughness (Ra <0.2μm) is controlled by mirror - finish calender rolls, minimizing haze.
Ideal for industries requiring visual inspection: electronics (component protection with status visibility), medical devices (sterile packaging with product viewing), and automotive interiors (trim protection without aesthetic compromise). The film's 1.35g/cm³ density and 150MPa tensile strength ensure scratch resistance while allowing operators to monitor protected items without removing the film.
Backed by ISO 9001 certification, the film undergoes 1000 - hour QUV aging tests, maintaining transparency with ΔE <3 color shift. Guangdayuan's 16,000㎡ facility uses automated gauging systems (thickness tolerance ±3%) to ensure batch - to - batch consistency, solving opacity issues for global clients in semiconductor, LCD, and medical sectors.
