Edge Lifting on Aluminum Panels? Why Your PE White Film Fails and How Guangdayuan Solves It

Edge lifting of PE white protective film on aluminum panels after just one week is a clear sign of poor adhesive balance. When the initial tack fades faster than the holding power, dust and moisture invade, ruining polished aluminum composite panels, stainless steel sheets, and decorative building facades. This common problem plagues the building hardware, home appliance, and transport protection industries, leading to costly rework and surface damage.

Guangdayuan solves this with over 20 years of formulation expertise and a deep partnership with Harbin Institute of Technology. Our PE white film uses premium raw materials from Toray, Toyobo, and SKC to create a specialized pressure-sensitive adhesive. It maintains a perfect balance between high initial tack and strong holding power, preventing edge lifting even after weeks of application on aluminum and other metals.

Our PE protective film series includes PE black and white film, PE electrostatic film, PE self-adhesive film, PE antistatic protective film, PE blue film, and PE electronic film. These are widely applied in consumer electronics, photovoltaic modules, automotive parts, and medical devices, ensuring clean removal and zero edge lifting across various surface energies.
