Healthcare and food packaging specialist Rollprint Packaging Products has introduced a second high-barrier structure Exponent 2 to its Exponent film range.
Exponent 2 is made with Rollprint's ClearFoil, a barrier-coated polyester which is coextruded with non-crystalline polyester sealant.
To be primarily used in pre-made or inline pouching, lidding and flow wrap applications, Exponent 2 provides a chemically neutral, ultra-high oxygen and water vapour barrier with chemical-resistance.
Rollprint Sales and Marketing vice-president Dwane Hahn said: "With Ineos's 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.
"In fact, Exponent 2 offers improved sealing characteristics over Barex due to easier-to-create hermetic seals and improved line speeds."
Exponent 2 features reduced number of layers and gauge when compared to traditional foil-based high-barrier structures.
"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," added Hahn.
Rollprint's Exponent 2 can also be used in packaging patch, e-cigarette and products from the diagnostics markets.
Exponent 2 may also be used for flexible packaging for the wine and spirits segment because of its organoleptic characteristics.
