Abstract
Disclosed are mono-layer or multi-layer films, sheets, or coatings wherein at least on layer comprises a fringed surface microstructure (1), a process for making these items and uses thereof. Further disclosed are articles of manufacture comprising such film, sheet, or coating.
Claims34
A mono-layer or multi-layer film, sheet, or coating comprising at least one layer that displays a surface microstructure, which layer is a thermoplastic polymeric material having fringes, wherein said fringes are non-perforated and are at least partially hollow with at least about 25 percent of the volume at the top of the fringe being empty and have a height of at least about 40 microns or more, in a density of 1000 or more per square centimeter.
A composite comprising a mono-layer or mufti-layer film, sheet, or coating wherein at least one layer displays a surface microstructure, which layer is a thermoplastic polymeric material and characterized by fringes, wherein said fringes are non-perforated and are at least partially hollow with at least about 25 percent of the volume at the top of the fringe being empty and have a height of at least about 40 microns or more, in a density of 1000 or more per square centimeter.
