Abstract:
1. A process for manufacturing a film laminate comprising (i) a liquid absorptive layer useful for imparting flavor and color evenly to meat, and (ii) an impermeable barrier layer wherein: A the liquid absorptive layer comprises a block copolyether ester polymer; and B the impermeable barrier layer comprises a structure selected from the group consisting of single film layers, multilayer films and laminates, the barrier layer comprising: (a) at least one layer comprising a polymer, wherein the polymer is selected from the group consisting of: polyamides; mixtures of polyamides; ethylene vinyl alcohol copolymers; polyvinylidene chloride; polyolefins; and mixtures of any of these; and (b) optionally at least one tie layer; and wherein the liquid absorptive layer has a moisture vapor transmission rate of from about 1200 to about 20,000 g 25 micron/m 2 24 hrs, the process comprising the steps of: (1) coextruding said block copolyether ester polymer and said at least one layer comprising a polymer to form a multilayer extrudate; and, (2) cooling the multilayer extrudate to form a film laminate.
