Abstract:
1. A laminate film structure, comprising a first film laminated to a second film, wherein the first film is a heat-sealable film structure comprising: (a) a core layer comprising a thermoplastic polymer, the core layer having a first side and a second side; (b) a functional layer on the first side of the core layer, wherein the functional layer is selected from the group consisting of a laminating layer, a printable layer, a laminating and a printable layer, and a sealable layer; and (c) a heat-sealable layer on the second side of the core layer comprising (i) a thermoplastic polymer and (ii) a slip system comprising a silicone gum having a viscosity in the range of 10 to 20 million centistokes present in amount from about 0.2 wt. % to about 2.0 wt. % of the heat-sealable layer and at least one antiblocking agent present in an amount from about 0.05 wt. % to about 0.5 wt. % of the heat-sealable layer; (d) wherein the second film is comprised of the same structure as the first film.
