摘要:
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.
