Rollprint Packaging Products has added a second high barrier structure to its Exponent film family. Exponent 2 features a combination of Rollprint’s ClearFoil and a coextruded non-crystalline polyester sealant. The material targets pharmaceutical and other chemically-sensitive applications which require exceptional barrier and clarity.
"With Ineos’ recent announcement that it is exiting the Barex acrylonitrile-methyl acrylate copolymer business, we wanted to let the industry know immediately that there is an alternative clear, high barrier structure," states Dwane Hahn, Rollprint’s vice president sales and marketing. "In fact, Exponent 2 offers improved sealing characteristics over Barex due to easier-to-create hermetic seals and improved line speeds."
ClearFoil, a barrier coated polyester, is coextrusion coated with a non-crystalline polyester sealant to create Exponent 2. Pre-made or inline pouching, lidding and flow wrap applications are anticipated to be the first commercialised package types.
Compared with traditional foil based high barrier structures, Exponent 2’s reduced number of layers and gauge are said to offer cost savings and create an improved environmental profile for a wide variety of pharmaceutical products. Its high barrier and clarity properties also make it a suitable replacement for glass vials.
