Abstract
The present disclosure provides a multilayer film. The multilayer film includes at least two layers including a sealant layer and a second layer in contact with the sealant layer. The sealant layer contains (A) a first ethylene-based polymer having a density from 0.895 g/cc to 0.925 g/cc and a melt index from 0.5 g/10 min to 30 g/10 min; (B) a branched fatty acid amide; and (C) a linear saturated fatty acid amide, wherein the branched fatty acid amide and the linear saturated fatty acid amide have a weight ratio of from 1:5 to 3:1. The second layer contains a second ethylene-based polymer.
