Abstract:
1. A multilayer film comprising: i. a base layer comprising a first polymer; ii. a tie layer comprising a second polymer; and iii. a sealant layer comprising an ethylene/α-olefin interpolymer, wherein the tie layer is between the base layer and the sealant layer and wherein the ethylene/α-olefin interpolymer of the sealant layer has (a) a DSC curve characterized by an area under the DSC curve from the melting peak temperature to the end of melting is at least about 17% of the total area under the DSC melting curve from −20° C. to the end of melting; (b) a multi-modal molecular weight distribution; (c) a density of from about 0.875 g/cc to about 0.915 g/cc; (d) a I (e) a molecular weight distribution in the range from about 2.0 to about 3.8; and (f) less than 0.01 long chain branches per 1000 carbon atoms.
