Barrier lidstock

A clear, high-moisture-barrier lidstock suitable for sealing to most plastic trays and cups is made from a wide variety of plastic materials. Flexi-Free(R) 6985 is said to be the first high-moisture-barrier lidstock without a foil layer designed for universal application. Plastic tray/cup materials can include HIPS, HDPE, PP, APET, PETG, PS, PVC, PC and Barex(R). The two-ply, 2.5-mil lamination lidding is made from PVDC-coated polyester and a peelable sealant layer. Its high MVTR characteristics make it suitable for powders, where it is undesirable to absorb moisture, as well as gels and liquids, to minimize evaporation, according to the co. The transparent structure offers product visibility prior to opening. Applications include cosmetics, health and beauty aids, neutraceuticals and medical devices.
