Ampac Flexibles Launches Clear, High-Moisture Barrier Lidstock Suitable for Most Plastic Trays/Cups

Ampac Packaging is also introducing a companion product—Flexi-Free 6734, which does not have a PVDC coating and is suitable for universal sealing applications which do not require a high MVTR.

19/04/07 Ampac Flexibles, a unit of Ampac Packaging LLC, introduces a new clear high-moisture (MVTR) barrier lidstock that can seal to trays, cups, etc., made from a wide variety of plastic materials.

Flexi-Free 6985 is said to be the first high MVTR lidstock without a foil layer that is suitable for universal application. Plastic tray/cup types include: high-impact polystyrene (HIPS), high-density polyethylene (HDPE), polypropylene (PP), amorphous polyethylene terephthalate (APET), polyethylene terephthalate glycol (PETG), polystyrene (PS), polyvinyl chloride (PVC), polycarbonate (PC) and Barex.

The two-ply, 2.5 mil lamination is made from polyvinylidene choride- (PVDC) coated polyester and a peelable sealant layer. Its high MVTR characteristics make it ideal for powders where it is undesirable to absorb moisture and for gels and liquids to minimize evaporation. The transparent structure also offers marketing advantages—customers are able to view the tray contents prior to opening. Targeted applications include: cosmetics, health and beauty aids, nutraceuticals, medical devices, etc.

Further, Flexi-Free 6985 can be peeled off cleanly without leaving a residue or contaminating the contents.

In addition to its performance characteristics, Ampac’s multipurpose Flexi-Free 6985 lidstock offers packagers and contract fillers running various tray/cup types significant inventory and cost savings. No longer is it necessary to purchase lidstock specific to a plastic material. This results in simplification of ordering, inventory, labor, cash flow, downtime, internal testing, etc.

Ampac Packaging is also introducing a companion product—Flexi-Free 6734, which does not have a PVDC coating and is suitable for universal sealing applications which do not require a high MVTR.
