PET Protective Film

Material & Craft

White spots or surface blooming on PE black and white film indicate additive migration — a telltale sign of recycled or contaminated raw materials. Cheap fillers and low-molecular-weight additives migrate to the surface, creating unsightly white specks. Guangdayuan uses only virgin resins from Toray and Toyobo. Our three-layer co-extrusion technology encapsulates the black core between white outer layers, permanently locking all additives inside.

Performance Features

Unlike recycled-content films that bloom with white spots, Guangdayuan‘s virgin-resin film stays visually flawless. No surface migration, no customer rejection, no costly rework. The black layer remains deep and uniform throughout the film’s life.
