Rollprint Packaging Products, Inc. announces the addition of 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 non-crystalline attributes enhance sealing properties.) The material targets pharmaceutical and other chemically sensitive applications requiring exceptional barrier and clarity.
Offers an alternative clear, high-barrier structure, and 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. Premade 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 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.
The Exponent family of films is engineered to meet performance requirements for pharmaceutical and other chemically sensitive products, but use less material to help manufacturers meet their cost objectives.
Exponent 2 provides 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 suitable for single-dose delivery systems and cosmetic applications because of its high surface-to-volume ratio and unique barrier properties.
