PET Film Supply Company is a manufacturer of Nano Hybrid Glass Screen Protector Film for smartphones, tablets, touch panels, car navigation screens, and industrial displays. The product combines a glass-like 9H functional surface, flexible handling, high transparency, and complete-surface silicone adhesion. Transparent grades can reach >=94% light transmittance and <=0.5% haze, subject to the approved laminate and test method. Supply options include sheets, blanks, and custom die-cut screen protector parts.

Product Overview
Nano Hybrid Glass Screen Protector Film is made for finished screen protection, not temporary manufacturing cover film or internal optical bonding. Although it may be sourced under the broader PET Film Screen Protector term, its working layer is a nano hybrid glass composite rather than ordinary polyester rollstock.
The flexible multilayer structure can be slit, sheeted, kiss cut, aligned, and installed with less breakage risk than thin rigid glass. The functional layer is typically 220-230 um thick. With removable protection and release liner, the supplied construction is generally 0.38-0.43 mm; this is not the thickness left on the display after installation.
A typical 45-55 um silicone layer contacts the complete viewing area. On a clean, compatible screen, it wets out gradually and moves trapped air toward the edge, supporting bubble-free lamination, even optical contact, and low-residue removal.
Shaped parts should follow an approved CAD or DXF drawing covering size, corner radius, edge clearance, openings, pull-tab position, liner direction, and orientation. Small holes, narrow frames, and sharp corners need extra review because they can cause coating cracks, silicone squeeze-out, liner shift, or edge lifting.
Benefits
– 9H pencil hardness helps limit routine surface marking.
– Flexible construction improves cutting, packing, alignment, and installation.
– >=94% transmittance and <=0.5% haze help preserve brightness and detail.
– Full-area silicone contact supports steady wet-out and edge-directed air release.
– Typical die-cut tolerances of +/-0.10 mm to +/-0.20 mm support accurate openings.
– The glass-like surface supports tapping, swiping, and stylus operation.
– Approved drawings and retained samples improve repeat-order consistency.
How Should 9H Hardness and Flexible-Glass Performance Be Verified?
The 9H value refers to pencil hardness, not Mohs hardness, drop resistance, or proof that the surface cannot be scratched. The record should state the method, pencil grade, load, angle, passes, surface condition, and tested layer. A commonly referenced condition is 9H at 750 gf, but final acceptance must follow the agreed specification.
Flexibility requires a separate check. Converted samples should be bent and inspected for whitening, microcracks, edge separation, optical distortion, or adhesion loss. Surface hardness alone does not confirm impact resistance or repeated-bending performance.

Packing and Loading
What Should Be Checked Before Full Silicone Adhesive Parts Enter Die Cutting and Lamination?
Adhesion should be tested on the intended display, not only standard glass. Oleophobic coatings, printed borders, recessed windows, and surface-energy differences can affect wet-out and peel behavior. Record positioning, bubble release, optical uniformity, removal behavior, residue, and edge condition after 24 hours.
After die cutting, inspect dimensions, openings, corners, liner alignment, cut-edge cleanliness, coating condition, and silicone squeeze-out. Touch testing should cover tapping, swiping, multi-touch, edge gestures, and stylus response. Vehicle and industrial parts should also be reviewed after agreed heat, humidity, cleaning-agent, and dwell exposure.
Applications
– Smartphones with camera, speaker, fingerprint, or sensor openings
– Tablets requiring clear images, stylus response, and edge gestures
– Car navigation displays with printed borders or recessed areas
– Industrial HMI panels requiring shaped parts and repeated cleaning
– POS terminals, kiosks, GPS devices, and equipment displays
– Capacitive touch panels requiring multi-touch or glove validation
FAQ
Is 9H the same as tempered-glass impact strength?
No. It describes pencil hardness, not drop, impact, or shatter resistance.
Can finished parts include custom openings and outlines?
Yes. Options include rounded corners, camera holes, speaker slots, sensor openings, pull tabs, and irregular profiles.
Does the silicone adhesive suit every display coating?
It suits many smooth displays, but wet-out, adhesion, and removal should be tested on the intended screen.
What should be approved before volume production?
Approve the construction, screen sample, drawing, tolerance, liner direction, optical appearance, touch response, and retained sample.
