Amlite heatflex recyclable high-barrier film

Overview

Retort packaging traditionally requires multi-material structures combining PET, aluminium, and polyolefin layers that cannot be recycled. AmLite HeatFlex replaces these with a mono-material polyolefin film coated with silicon oxide (SiOx) at Amcor's vacuum deposition facility in Switzerland. The retortable grade achieves moisture barrier performance of less than 1 gram after pouch converting and retort processing. Amcor invested in a dedicated production line at its Lugo di Vicenza, Italy facility in 2026. The film runs on customers' existing packaging lines without modification.
