Abstract
A film structure having a base layer comprising a film-forming thermoplastic polymer; and a heat-seal layer having a seal-initiation temperature less than or about 130° C. and comprising from about 50 to about 98 wt % of a first polymer component and about 2 to about 50 wt % of a second polymer component. The first polymer component comprising propylene-derived units and, optionally, up to about 20 wt % of comonomer units derived from a Cand/or C-Cα-olefin, and having a heat of fusion greater than 75 J/g and a melting point greater than or equal to 105° C. The second polymer component comprising at least 75 wt % propylene-derived units, and having a melting point less than 105° C. and a heat of fusion less than 75 J/g.
