There are two types of self-healing screen protectors for the cutting machine: HD Clear and Matte. The packaging specification is 50 pieces per box (dimensions: 21x13x2.5 cm) and 1,600 pieces per carton(dimensions: 44x29x24 cm).

The self-healing function of screen protectors is made possible by the high elasticity and ductility of TPU material. When a small scratch appears on the surface, the TPU material gradually returns to its original shape through its inherent elasticity, reducing the visibility of the scratch. While it cannot completely remove all scratches, it is highly effective for minor ones.

We currently offer three types of intelligent film cutters: the MTB-CUT M288, MTB-CUT 180T, and MTB-CUT M188 screen protector machines. The MTB-CUT M288 is the latest model, featuring automatic installation of screen protectors and vacuum curing.

Tempered glass screen protectors have high hardness and strong scratch resistance, making them suitable for flat screens and providing better impact protection. Hydrogel screen protectors, on the other hand, are mainly made from TPU material, offering high transparency and elasticity. They are highly stretchable, softer, and are ideal for 3D curved screens, perfectly fitting the edges of the phone. They also have a certain self-repair ability for minor scratches. Tempered glass protectors feel relatively harder but have excellent light transmittance, while hydrogel protectors feel softer, have better adhesion, but their transparency is slightly lower than that of tempered glass screen protectors.
