Flex Films, the global film manufacturing arm of flexible packaging giant UFlex, is set to launch its new avant-garde patented BOPET high barrier film F-UHB-M, designed to replace aluminum foil in flexible packaging applications. To be manufactured in Flex Films Kentucky plant and supplied across the world, F-UHB-M addresses challenges of the Converting Industry that has relied for long on aluminum foil for packaging despite several of its limitations including material availability, high material cost, weak integrity, propensity for in-use pinhole formation and difficulty in recycling.
With its new specially formulated bi-axially oriented, polyester (BOPET) structure, F-UHB-M comes with superior gas and water barrier while achieving one of the lowest oxygen and moisture barrier values (0.1 cc/ m2-day & 0.1 gm/m2-day respectively) and industry-leading metal adhesion of 1200 gm/25mm that aids improvement and extension of product shelf-life. Barrier performance is retained after incorporation of F-UHB-M into a multi-layer laminate structure demonstrating excellent handling, machinability and resistance to pin-hole formation.
