Embodiments of the present invention relate to multilayer films, laminates, and articles. In one aspect, a multilayer film comprises (a) a first layer comprising a first composition, wherein the first composition comprises at least one ethylene-based polymer and wherein the first composition has a density of less than 0.935 g/cm3, a melt index (I2) of less than 2.0 g/10 minutes, a MWCDI value greater than 0.9, and a melt index ratio (I10/I2) that meets the following equation: I10/I2≥7.0−1.2×log(I2), wherein the first layer comprises at least 50 percent by weight of the first composition based on the weight of the first layer; (b) a second layer comprising a first polyethylene having a density of greater than 0.950 g/cm3 and a melt index (I2) of less 2.0 g/10 minutes, wherein the second layer comprises at least 40 percent by weight of the first polyethylene based on the weight of the first layer; and (c) a sealant layer, wherein the multilayer film comprises at least 29 weight percent of the first composition based on the total weight of the film, and wherein the multilayer film comprises at least 15 weight percent of the first polyethylene based on the total weight of the film.
