Abstract
In embodiments herein, the invention relates to a multilayer printable polymeric film including: (a) at least one layer A including one or more polyolefins and having a first side and a second side; (b) a layer B including one or more polyolefins and having a first side and a second side, where the first side of layer B is located on the second side of layer A; and (c) a printable coating located on the first side of layer A; wherein at least one of layer A or B comprises 0.01 to 50.0 wt. % of at least one polyether-polyolefin block copolymer, based on the weight of the polymers comprising the layer; and wherein the multilayer printable polymeric film has a kinetic coefficient of friction less than 0.65; and a surface tension of greater than about 35 mN/m; on one or both sides of the film.
