"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," said Dwane Hahn, vice president sales and marketing, Rollprint. "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 commercialized package types.
When compared to traditional foil-based high-barrier structures, Exponent 2's reduced number of layers and gauge offer cost-savings and create an improved environmental profile for a wide variety of pharmaceutical products. The structure's high-barrier and clarity properties also make it a suitable replacement for glass vials, where cost and breakage continue to challenge manufacturers.
"We have engineered the Exponent family of films to meet performance requirements for pharma and other chemically-sensitive products, but use less material to help manufacturers meet their cost objectives. We also wanted to offer clarity attributes not possible with foil-based structures and give companies an alternative to glass vials," said Hahn.
Exponent 2 has been engineered to provide a chemically neutral, ultra-high oxygen and water vapor barrier with chemical resistance. Oxygen barrier levels are available as low as 0.0008 cc/100in2-24 hrs. and water vapor barrier properties are available down to 0.0008 g/100in2-24 hrs.
The transdermal patch, e-cigarette and diagnostics markets are the first application opportunities Rollprint envisions for this technology. Exponent 2 is also an excellent candidate for single-dose delivery systems and cosmetic applications because of its high surface-to-volume ratio and unique barrier properties. Additionally, the high-barrier film is ideally suited for the emerging flexible packaging for wine and spirits segment because of its outstanding organoleptic characteristics.
