The high-definition invisible hydrogel film for the iPhone16 Series provides a crystal-clear display with original colors and high transparency. It offers a smooth touch experience, resistance to oil and fingerprints, scratch resistance, and automatic repair capabilities. The film is designed to prevent edge breakage with a spider web structure shock-absorbing layer, providing strong flexibility and protection against impact. The surface is coated with memory molecular layer with hydrophobic and oleophobic functions to resist fingerprints and oil stains, keeping the phone clean and smooth at all times. The film also features high rebound technology to protect against daily impacts, utilizing microcrystalline slow rebound factors to prevent cracking. The nano multi-layer hydrogel film is processed with multiple layers and fusion techniques, combining various advantages such as automatic scratch repair, strong resistance to fingerprints, scratch repair layer, fingerprint recognition layer for quick unlocking, sensitive touch control layer, slow rebound shock-absorbing layer, high-quality ATU base layer, and high-quality high-viscosity adhesive full glue layer.
