Multilayer films and methods thereof

A multilayer blown film comprising a cling layer and a release layer, wherein:

• the cling layer comprises:
• (i) an ethylene/alpha-olefin elastomer that is not an olefin block copolymer comprising greater than 50%, by weight, of units derived from ethylene, and having a density in the range of 0.855 to 0.890 grams/cm3 and a melt index, I2, in the range of 0.1 to 30 grams/10 minutes;
• and
• (ii) a polyethylene polymer selected from ultra-low density polyethylene, a very low density polyethylene, or combinations thereof, wherein the polyethylene polymer has a density in the range of 0.885 to 0.915 grams/cm3, a melt index, I2, in the range of 0.1 to 30 grams/10 minutes, and a purge fraction greater than 20 percent as determined by a Crystallization Elution Fractionation (CEF) test method;
• and
• the release layer comprises an ethylene/alpha-olefin resin that is characterized by the following properties:
• (a) a melt index, I2, of from 0.1 to 30.0 g/10 min;
• (b) a density of from 0.910 to 0.930 g/cc;
• and
• (c) a purge fraction of less than 2% as determined by Crystallization Elution Fractionation (CEF) test method;
• wherein the release layer further comprises a low density polyethylene.
