Abstract: A polymeric film including a major surface having a plurality of intersecting extended structures is described. For at least a majority of the structures in the plurality of extended structures: each structure extends along a length of the structure, has an average width along a direction transverse to the length and generally along the first major surface, and has an average height along a direction generally perpendicular to the first major surface; and the average width of the structure may be in a range of 1 to 200 micrometers, the average height of the structure may be in a range of 1 to 200 micrometers, and the length may be at least 3 times the average width. The extended structures may be randomly or pseudorandomly oriented and may be formed by microreplicating a surface of a paper.

Abstract: Various embodiments described herein relate to a laminate. The laminate includes a release liner comprising at least one polyolefin and an adhesive layer. The adhesive layer contacts a region of a first major surface of the release liner. Upon exposure to laser electromagnetic radiation, the adhesive layer is configured to absorb at least 55% (in some embodiments, at least 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, or even 100%) of the laser electromagnetic radiation and the release liner absorbs no greater than 45% (in some embodiments, no greater than 40%, 35%, 30%, 25%, 20%, 15%, 10%, 5%, or even 0%) of the laser electromagnetic radiation.
