Abstract

According to various examples, an assembly can include a backing. The assembly can also include a polymeric surfacing film adhered to the backing, the polymeric surfacing film. The polymeric surfacing film can include a first geometric shape. The polymeric surfacing film includes a continuous first cut defining the geometric shape and a continuous second cut spaced apart from and substantially congruent with the continuous first cut in at least one of an x and y direction. A portion of the polymeric surfacing film, located between the first cut and the second cut, is removable from the backing. According to some examples, the assembly can provide certain benefits over state of the art assemblies. For example, according to some examples, providing the first and second cut can make removal of at least the first geometric shape to be quicker and easier, which can result in significant savings in time and wasted materials.

First claim

What is claimed is:

1. An assembly comprising:
a backing; and
a polymeric surfacing film adhered to the backing, the polymeric surfacing film being at least partially self-healing and comprising:
a continuous first cut defining a first geometric shape; and
a continuous second cut spaced apart from and substantially congruent with the continuous first cut in at least one of an x and y direction such that at least 80% of the continuous second cut is congruent with that of the continuous first cut, wherein a portion of the polymeric surfacing film located between the first cut and the second cut is removable from the backing.

2. The assembly of claim 1 , wherein the first cut and the second cut are spaced from about 0.5 mm to about 20 mm apart.

3. The assembly of claim 1 , wherein the first geometric shape comprises an interior feature defined by a continuous third cut defining the interior feature and a continuous fourth cut substantially congruent with the continuous third cut.

4. The assembly of claim 1 , wherein the polymeric surfacing film comprises a second geometric shape different than the first geometric shape and comprising a fifth cut defining the second geometric shape and a sixth cut spaced apart from and substantially congruent with the first cut.

5. The assembly of claim 1 , wherein the second cut defines at least one incongruent portion.

6. The assembly of claim 5 , wherein the incongruent portion defines a tab.

7. The assembly of claim 1 , wherein the backing comprises a material chosen from at least one of a paper and a polyethylene liner, wherein the polyethylene liner optionally includes a release coating.

8. The assembly of claim 1 , wherein the polymeric surfacing film comprises a polyurethane.

9. The assembly of claim 1 , wherein at least one of the first and second geometric shapes is a paint protection polymeric surfacing film, a window tint polymeric surfacing film, or a component thereof.
