Multilayer films and methods of making the same

A multilayer film, comprising two outer layers and a core layer between the two outer layers, wherein each of the two outer layers comprise from about 60 wt % to about 80 wt % of a first polyethylene and from about 40 wt % to about 20 wt % of a second polyethylene, based on the total weight of each outer layer, and the core layer comprises from about 40 wt % to about 60 wt % of a first polyethylene and from about 60 wt % to about 40 wt % of a third polyethylene, based on the weight of the core layer, wherein:

• (i) the first polyethylene is derived from ethylene and one or more C3 to C20 α-olefin comonomers, and is a metallocene polyethylene (mPE) having a density of about 0.910 to about 0.940 g/cm3, a melt index (MI), I2.16, of about 0.1 to about 15, a molecular weight distribution (MWD) of about 1.5 to about 5.5, and a melt index ratio (MIR), I21.6/I2.16, of about 10 to about 25;
• (ii) the second polyethylene is derived from ethylene and one or more C3 to C20 α-olefin comonomers, and has a density of about 0.915 to about 0.940 g/cm3, an MI, I2.16, of about 0.1 to about 5, an MWD of about 2.5 to about 5.5, and an MIR, I21.6/I2.16, of greater than 25 to about 100;
• and
• (iii) the third polyethylene has a density of about 0.940 g/cm3 to about 0.965 g/cm3;
• wherein the multilayer film has at least one of the following properties:
• (i) a non-breakage rate (EMC method) of about 60% to about 100% when laminated to a polyester substrate film;
• and (ii) a non-breakage rate (EMC method) of about 60% to about 100% when laminated to a polyethylene substrate film.
