Ever wondered what goes into a screen protector that lasts? For Guangdayuan’s 3-layer high-transparency scratch-resistant PET protector for phone screens, the journey starts in state-of-the-art labs and ends as a must-have accessory for millions in the Middle East and Southeast Asia.
Research is the foundation. Collaborating with Harbin Institute of Technology, Guangdayuan’s engineers developed a proprietary blend of PET materials that balances flexibility and strength. The 3-layer structure—each layer designed for a specific function—underwent thousands of tests: scratch resistance with steel wool, transparency under various light conditions, and adhesion in high humidity.
Production is equally meticulous. In their 16,000㎡ facility, automated coating machines apply layers with micron-level precision, while quality inspectors check every batch against ISO standards. This commitment to excellence ensures that whether you’re in Dubai’s desert heat or Jakarta’s rain, the protector remains intact.
What does this mean for users? A product that protects against daily wear without compromising on touch sensitivity or display quality. It’s compatible with fingerprint sensors and works with most phone cases, adding convenience to its list of benefits.
Guangdayuan’s vision—to lead in eco-friendly surface materials—shines through here. The PET protector is recyclable, reducing environmental impact without sacrificing performance. For consumers and businesses prioritizing sustainability, this is a clear choice.
When you choose Guangdayuan, you’re choosing decades of expertise, innovation, and a promise to protect what matters most.
