ADDISON, ILL. — ClearFoil X and ClearFoil Z, two additions to a transparent ClearFoil line, have shown the ability to replace aluminum foil structures in demanding applications, according to Rollprint Packaging Products, Inc. ClearFoil Z reaches ultra-high oxygen barrier properties and moisture barrier properties while ClearFoil X also has higher oxygen barrier properties and moisture barrier properties than other non-foil structures, according to the company.

The films may be used for moisture-sensitive and oxygen-sensitive food applications as well as pharmaceutical applications.

“Because pinholes are inherently present in thin gauge foils, they can impact barrier properties,” said Doug Dodrill, vice-president of technology for Addison-based Rollprint Packaging Products. “As a result, ClearFoil X and Z can outperform structures made from the most common foils.”

The two new barrier films achieve the barrier properties through aluminum oxide-coated polyester, which may be either laminated or extrusion-coated with any of Rollprint’s proprietary sealant technologies.
