The present invention provides coated films and packages formed from such films. In one aspect, a coated film comprises (a) a multilayer polymeric film having opposing facial surfaces, wherein a firstfacial surface has a root mean square surface roughness of at least 80 nm when measured using image analysis with an atomic force microscope and wherein a second facial surface has a root mean squaresurface roughness of less than 80 nm when measured using image analysis with an atomic force microscope; and (b) a coating on at least a portion of the first facial surface, wherein the coating comprises polyurethane, wherein the film comprises at least one of polyethylene, polypropylene, polyethylene terephthalate, or polyamide, and wherein the coated film has a Zebedee clarity of at least 2% when measured according to ASTM D1746/15 in the coated portion of the first facial surface. 本发明提供涂布膜和由所述膜形成的包装。在一个方面中，涂布膜包括(a)具有相对正面表面的多层聚合膜，其中当通过原子力显微镜使用图像分析测量时，第一正面表面具有至少80nm的均方根表面粗糙度，并且其中当通过原子力显微镜使用图像分析测量时，第二正面表面具有小于80nm的均方根表
