F-UHB-M addresses the converting industry ’ s challenges that have relied on aluminum foil for packaging for a long time . Amongst foil ’ s limitations are its 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 provides superior gas and water barrier – achieving one of the lowest oxygen and moisture barrier values ( 0.1 cc / m2-day & 0.1 gm / m2-day , respectively ). The new structure ’ s industry-leading metal adhesion of 1200 gm / 25mm aids improvement and extension of product shelf-life . Barrier performance is retained after incorporating F-UHB-M into a multi-layer laminate structure , demonstrating excellent handling , machinability , and resistance to pinhole formation .
Flex Films ’ new film will be shown to industry visitors at Pack Expo 2021 , at the Las Vegas Convention Centre from 27 to 29 September 2021 , at the Flex Films stand N-9115 . The new F-UHB-M film has a thickness of 12 microns . Its coating technology and a very high optical density are compatible with a wide range of inks and adhesives . In addition , it has better machinability and handling during processing . Flex says it comes with good flex crack resistance and has 20 % increased puncture resistance vs BOPET grades .
