The Difference Between PET Film and Tempered Glass Screen Protectors?

1.Material and Structural Differences

  PET Film: Made from thermoplastic polyester (PET) plastic, typically featuring a single-layer or double-layer structure. The outer layer is a release film to prevent dust contamination, while the inner layer contains a silicone coating to enhance adhesion.

  Tempered Glass Screen Protector: Constructed from tempered glass, typically featuring a 4-layer structure: special coating → tempered glass → explosion-proof layer → silicone coating. Thickness generally ranges from 0.1 to 0.4 millimeters.

2.Protection Performance Comparison

  PET Film: Strong scratch resistance effectively prevents daily wear and tear, but cannot withstand screen shattering from drops.

  Tempered Glass Screen Protector: High hardness and impact resistance absorb shock forces, significantly reducing screen shattering risk.

3.Light Transmission & Cost

  PET Film: Light transmission approaches the original screen (approx. 90%), with lower cost, suitable for budget-conscious users.

  Tempered Glass Screen Protector: Offers up to 98% light transmission but carries a higher cost and is prone to edge damage.

4.User Experience and Durability

  PET Film: Lightweight and easy to apply, with quick air release and no residue, ideal for users prioritizing simplicity.

  Tempered Glass: Resists fingerprints and oil stains, though long-term use may cause edge lifting or bubbles that affect aesthetics.

PET screen protectors are suitable for daily scratch protection and offer good value for money, while tempered glass protectors are ideal for frequent use or users requiring enhanced protection. When choosing, balance protection needs with cost based on your requirements.
