Protective film

PET films are made of transparent plastic with a thickness of several hundred microns. The film, when properly applied, is therefore invisible to the eye without close scrutiny. The film efficiently copes with small particles scratching the glass.

However, the strength properties are not sufficient to absorb the mechanical energy of an impact or fall on the floor. In addition, PET film wears out quickly and must be replaced 1-2 times a year or more.

Main advantages

  • The low thickness makes the film inconspicuous on glass.
  • Available in coloured, glossy and matt.
  • Resistant to abrasive particles.

Main disadvantages

  • Poor protection properties.
  • The price of some films is comparable to the price of straight glass.
  • Rapid wear and tear, requiring regular replacement of the film.
  • Low prevalence.
  • Difficult to install.

Hydrogel films

Visually similar to conventional PET film. It’s formulated with materials that can absorb moisture and repair any scratches or abrasions that may have occurred in the film. Deep scratches become less visible, while small scuffs are difficult to see without a closer look. The durability characteristics are also comparable to conventional PET film.

Main advantages

  • The film is invisible when applied correctly.
  • Small scratches on the surface can be repaired.
  • Longer service life than conventional PET film.
  • Easy installation.

Main disadvantages

  • Low protective properties.
  • Scratches can take 3-4 days to restore.
  • Deep scratches do not disappear completely.

The magnetic case made of tempered glass

The magnet sleeve consists of two magnetically secured halves. The frame is made of metal, and the front and back sides are made of transparent glass. The smartphone is inserted into the case, thus achieving a all-around protection.

Main advantages

  • All-around protection for your smartphone.
  • Affordable cost of the case.
  • Easy installation and maintenance.

The main disadvantages.

  • Limited availability.

Armoured film

This type of film is made of polyurethane, and the thickness is superior to vinyl and PET counterparts. Because of this, the coating better copes with the impact of abrasive particles and hard objects on the smartphone. Films are available with markings for the lid only or for the lid and ends.

Armoured films are available in clear and different patterns. Available in glossy and matt types of films. Some films are capable of restoring scratches by the action of heat, e.g. blow-drying with a hairdryer.

Main advantages

  • Highest durability amongst films.
  • Different types: matt and glossy, transparent and patterned.
  • Marking under the cover only or under the cover and ends of the phone.
  • Ability to repair scratches under the influence of warm air.

Main disadvantages

  • Only available for a limited number of phones.
  • Not all armour films are capable of restoring scratches under warm air.
  • The strength characteristics are inferior to tempered glass.
