## Abstract

A printable reusable gel film formed of a polyvinyl acetic acid (PVA) or polyvinyl alcohol (PVOH) layer, a carrier layer, an acrylic adhesive layer, an elastic plastic sheet layer, an elastomer layer and a strippable plastic film is disclosed. The polyvinyl acetic acid (PVA) or polyvinyl alcohol (PVOH) layer and the carrier layer each have a protruding portion for guidance in printing. The strippable plastic film has perforations for ventilation to prevent accumulation of air during printing, assuring a high level of printing quality.

## Claims

### Claim 1

A printable reusable gel film
a polyvinyl acetate (PVA) or polyvinyl alcohol (PVOH) layer defining an opposing front surface and back surface, said polyvinyl acetate (PVA) or polyvinyl alcohol (PVOH) layer comprising a protruding portion extended from end thereof;
a carrier layer defining an opposing front surface and back surface, the front surface of said carrier layer being bonded to the back surface of said polyvinyl acetate (PVA) or polyvinyl alcohol (PVOH) layer, said carrier layer comprising a protruding portion extended from one end thereof and bonded to the protruding portion of said polyvinyl acetate (PVA) or polyvinyl alcohol (PVOH) layer, wherein the protruding portion of said polyvinyl acetate (PVA) or polyvinyl alcohol (PVOH) layer and the protruding portion of said carrier layer protrude over one respective end edge of said acrylic adhesive layer, one respective end edge of said elastic plastic sheet layer, one respective end edge of said elastomer layer, and one respective end edge of said strippable plastic film;
an acrylic layer defining an opposing front surface and back surface, the front surface of said acrylic layer being bonded to the back surface of said carrier layer;
an elastic plastic sheet layer made from polyvinyl chloride (PVC) or polyethylene terephthalate (PET) and defining an opposing front surface and back surface, the front surface of said elastic plastic sheet layer being bonded to the back surface of said acrylic adhesive layer;
an elastomer layer formed of a mixture of an elastomer solute and toluene solvent and coated on the back surface of said elastic plastic sheet layer; and
a strippable plastic film covered on one side of said elastomer layer opposite to said elastic plastic sheet layer, said strippable plastic film comprising a plurality of perforations.

### Claim 2 (depends on 1)

The printable reusable gel film as claimed in claim 1, the combined thickness of said polyvinyl acetate (PVA) or polyvinyl alcohol (PVOH) layer, said carrier layer, said acrylic adhesive layer, said elastic plastic sheet layer, said elastomer layer, and said strippable plastic film layer is in the range of 0.2 mm˜0.8 mm.

### Claim 3 (depends on 1)

The printable reusable gel film as claimed in claim 1, wherein said elastomer layer is formed of an elastic rubber sheet being attached to the back surface of said elastic plastic sheet layer and then baked in a bake oven at 170° C.˜220° C.
