Abstract
Systems and films for protecting surfaces of various substrates, including electronic devices, such as portable electronic devices, include a liner with a strip liner and a main liner. The strip liner, which covers a small strip of adhesive on the back side of a protective film, is configured to be removed before the main liner. With the small strip of adhesive exposed, the protective film may be aligned with a substrate and, if necessary, removed from the substrates and repositioned thereon. Thereafter, the main liner may be removed to enable complete application of the protective film to the substrate. Methods for securing protective films to substrates are also disclosed.
Claims20
A system for applying a protective film to an electronic device, comprising:
- a protective film including a lower surface that carries adhesive material and an upper surface opposite from the lower surface;
- a cap shield over the upper surface of the protective film and removable from the protective film upon securing the protective film to the electronic device;
- and
- a liner secured to the adhesive material on the lower surface of the protective film and including a liner strip, a main liner, and a breakable boundary that can be fractured between the liner strip and the main liner.
A system for applying a protective film to an electronic device, comprising:
- a protective film including a lower surface that carries adhesive material and an upper surface opposite from the lower surface;
- a cap shield over the upper surface of the protective film and removable from the protective film upon securing the protective film to the electronic device;
- and
- a liner secured to the adhesive material on the lower surface of the protective film, the liner including a liner strip and a main liner, the liner including a breakable boundary between the liner strip and the main liner, the breakable boundary enabling the liner strip to be fractured from the main liner and to be removed from the adhesive material without removing the main liner from the adhesive material.
A system for applying a protective film to an electronic device, comprising:
- a protective film including an adherent surface that carries adhesive material and an outer surface opposite from the adherent surface;
- a liner secured to the adhesive material on the adherent surface of the protective film, the liner including:
- a liner strip covering a strip of the adhesive material on the adherent surface of the protective film, the liner strip including a first tab protruding beyond an edge of the liner strip and a corresponding edge of the protective film so as to enable removal of the liner strip from the strip of the adhesive material;
- and
- a main liner covering a remainder of the adhesive material on the adherent surface of the protective film, the main liner including a second tab protruding beyond an edge of the main liner and a corresponding edge of the protective film;
- and
- a cap shield over an outer surface of the protective film and removable from the protective film upon securing the protective film to the electronic device.
