Abstract

Article comprising first and second continuous polymeric layers having at least one polymeric layer exhibiting a random network of strands and connective regions disposed between the first and second continuous polymeric layers. In some embodiments, the article is a tape and polymeric multilayer film having a slip resistant surface.

Claims (6)

1. An article comprising a first continuous polymeric layer, a second continuous polymeric layer, and a polymeric multilayer film disposed between the first continuous polymeric layer and the second continuous polymeric layer, wherein the polymeric multilayer film comprises a plurality of blown polymeric film layers each exhibiting a random network of strands and connective regions, wherein the random network of strands has a first optical density and the connective regions have a second optical density, and wherein the first optical density is greater than the second optical density.

2. The article of claim 1 , wherein at least one polymeric layer in the plurality of blown polymeric film layers has an open porosity of at least 20 percent.

3. The article of claim 1 , wherein at least one polymeric layer in the plurality of blown polymeric film layers is separable from a remainder of the polymeric multilayer film.

4. The article of claim 1 , wherein at least one of a first major surface or a second major surface of the polymeric multilayer film has a coefficient of friction of at least 0.4.

5. The article of claim 1 that is a graphic article.

6. The article of claim 1 that is a tape.
