Abstract:
The invention provides for a film including a layer made from a composition, the composition produced from 30 percent by weight or more of a first polymer component (FPC), wherein said FPC includes a copolymer of propylene and from 6 to 30 percent by weight of another alpha-olefin, and having a melting point derived from stereoregular polypropylene sequences, as determined by differential scanning calorimetry (DSC) of 105° C. or less, and a heat of fusion of 45 J/g or less; and a second polymer component (SPC); wherein the SPC includes a thermoplastic polymer other than the FPC.
