Clear film with high barrier properties for pharmaceutical applications.
Roll print 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. 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.
