With the introduction of Rollprint Packaging Products’ ClearFoil® X and ClearFoil® Z, clear ultra-high barrier packaging options can now replace aluminum foil structures for very demanding applications, says the company. ClearFoil® Z is said to be the first transparent, non-aluminum foil, flexible structure to reach ultra-high oxygen (O2) barrier properties of 0.0008 cc/100in2/24 hrs and moisture barrier properties of 0.0008 g/100in2/24 hrs. ClearFoil® X performs at 0.004 cc/100in2/24 hrs and 0.004 g/100in2/24 hrs, respectively. The two new barrier films achieve the properties via aluminum oxide-coated polyester which can be either laminated or extrusion-coated with any of Rollprint’s proprietary sealant technologies for added functionality. They have been engineered as transparent alternatives to traditional foil structures.
