Vacuum-deposited metallized films have traditionally been considered unsuitable for retort processing. That belief was defied by a result presented at K2025 by Br\u00fcckner Maschinenbau (Germany, \u201cBr\u00fcckner\u201d), BOBST (Switzerland), and
Mitsui Chemicals (Japan). The three companies presented mono-material, recyclable, high-barrier retort packaging developed through a decade of international collaboration.<\/p>\n\n\n\n

Retort pouches enable long-term preservation by sealing food products and applying high-temperature, high-pressure (retort) sterilization (at 121\u2013128\u00b0C for at least four minutes). This process requires strong gas-barrier and light-shielding properties, protection against oxygen and moisture ingress, and resistance to retort sterilization temperatures. Because metal corrosion and barrier loss caused by film shrinkage are inevitable in retort processing, multilayer laminates using polyethylene terephthalate (PET), aluminum foil, polypropylene (PP), and other materials have become standard. However, this structure has made recyclability
largely impossible.<\/p>\n\n\n\n
