Apple Tests Tougher Film for Foldable iPhone to Stand Out
Apple is evaluating a tougher protective film—likely clear polyimide—over the foldable iPhone’s ultra-thin glass to improve durability and feel, testing CPI vs PET as options. CPI would offer harder, more scratch‑resistant surfaces, with Kolon Industry and Lens Technology among the expected suppliers. A final decision is imminent as Apple continues component testing, with rumors pointing to a 7.8-inch inner display, a 5.5-inch cover display, Touch ID, and a launch alongside the iPhone 18 Pro lineup later this year.
