Micro-Bubbles Expanding After Heat Aging? Guangdayuan‘s Micro-Vent PE Electronic Film Prevents Growth
Material & Craft
Micro-bubbles trapped during PE electronic film application expand under high-temperature aging because ordinary films lack air-escape pathways. Trapped air expands with heat, creating visible bubbles that fail inspection. Guangdayuan solves this with micro-vent channel technology. Developed through our partnership with Harbin Institute of Technology, our adhesive surface features sub-micron grooves that allow air to escape during lamination — and prevent bubble regrowth during heat aging.
