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 0.900 g/cc to 0.925 g/cc and a melt index from 0.5 g/10 min to 30 g/10 min; and (B) a polyethylene-polydimethylsiloxane block copolymer having a weight average molecular weight from 1,000 g/mol to 10,000 g/mol. The second layer contains a second ethylene-based polymer.
