PET (Polyethylene Terephthalate) screen protectors are made of a high-quality polyester film with a scratch-resistant matte or glossy coating. They are the most common and cost-effective choice for basic screen protection on smartphones, tablets, and industrial touch screens.
Crystal Clear Clarity: High light transmittance ensures that your display remains vibrant and sharp.
Ultra-Thin Profile: Usually only 0.1mm thick, meaning they don't add bulk to your device and maintain high touch sensitivity.
Scratch Resistance: Effectively shields your screen from everyday hazards like keys, coins, and fingernails.[3]
Budget-Friendly: The most affordable protection option, often sold in multi-packs.[4]
Lightweight: Ideal for portable devices where keeping weight down is a priority.

Is a PET Protector Right for You?
Choose PET if:
You want to prevent fine scratches without spending much.
You prefer a protector that is almost invisible and doesn't change the thickness of your device.
You are using the device in a controlled environment (office, home) where major drops are unlikely.
Consider other options if:
You work in a rugged environment (Tempered Glass is better for impact).
Your device has a heavily curved "waterfall" screen (TPU/Hydrogel fits curves better).
Clean the Screen: Use an alcohol wipe or microfiber cloth to remove all oil and dust.
Remove Dust: Use a dust-removal sticker to pick up any tiny remaining particles (dust causes bubbles!).
Align the Protector: Peel back the first layer (labeled "1") and align the protector with the edges and camera cutouts.
Apply & Smooth: Gently lay the protector down and use a squeegee or credit card to push air bubbles toward the edges.
Remove Final Layer: Once perfectly placed, peel off the top protective layer (labeled "2").
Cleaning: Wipe with a dry microfiber cloth. Avoid harsh chemicals that might degrade the plastic.
Replacement: If you notice deep scratches or the edges beginning to lift, it’s time to swap it for a fresh one from your multi-pack.
