Abstract: According to one or more embodiments of the present disclosure, a coated film may be made by a process that may include applying an uncured polyurethane precursor between a polyolefin film and a release liner such that a first surface of the release liner is in contact with the uncured polyurethane precursor, curing the uncured polyurethane precursor to form a cured polyurethane layer positioned between the polyolefin film and the release liner, and removing the release liner to form the coated film comprising the polyolefin film and the cured polyurethane layer. The first surface of the release liner may have an optical finish. The curing may impart an optical finish to the cured polyurethane layer substantially similar to the optical finish of the first surface of the release liner.
