Summer Heat Causing Bubbles Between Your Aluminum Profile Film and Metal? Here's Why
Material & Craft
Bubbles or blistering between aluminum profiles and PE protective film in summer heat are caused by trapped air expanding under high temperature combined with poor film permeability. Ordinary films lack micro-ventilation properties, turning small air pockets into large bubbles. Guangdayuan solves this with micro-permeable technology, developed through our partnership with Harbin Institute of Technology, using premium raw materials from Toray and SKC.
Performance Features
Unlike ordinary films that bubble at 45°C, Guangdayuan‘s micro-permeable film withstands summer heat without blistering. The balanced adhesive prevents softening while allowing gas escape. No edge lifting, no bubble expansion, and zero residue upon removal—even after weeks in hot containers or outdoor storage.
Custom Service
We can customize different thickness, width, viscosity and roll length according to customer requirements.
