Abstract: This invention relates to a film including (i) at least one sealing layer, including greater than 50.0 wt. %, based on the total weight of the sealing layer, of a modifier, the modifier including a copolymer of propylene derived units and one or more comonomers selected from the group consisting of C2 and C4 to C10 alpha-olefin derived units, wherein the comonomer content is in the range of about 2.0 to 25.0 wt. %; and (ii) at least one core layer, including a polymer having a propylene derived unit content of greater than 90 wt. %, based on the weight of the polymer; and wherein the film has a seal initiation temperature of 105° C. or less; and wherein when a seal is formed, the sealed film has a hermeticity of 65% or more. The invention also relates to methods to produce such films, articles including such films, and the use of such films to form heat sealed articles.

Abstract: Provided are films wherein at least one layer of the film comprises a first polymer component and a second polymer component. The first polymer component comprises propylene-derived units and ethylene-derived units and/or a C4 to C20 alpha-olefin. The second polymer component comprises ethylene-derived units and a units derived from a co-polymerizable ethylenically unsaturated ester. The films are particularly useful in stretch hood applications.
