With a focus on global sustainability and aligned with its “from Plastic to Purpose” campaign, Ahlstrom-Munksjö Oy, Helsinki/Finland, has released a mono-material oxygen barrier technology made of 100% cellulose fibers.
The PureBarrier technology is based on Genuine Vegetable Parchment (greaseproof paper) and boasts numerous attributes including oxygen and gas barrier properties as well as natural wet strength. It is naturally grease resistant, does not contain any loose fiber or added chemicals, and can be made heat sealable with a biopolymer which makes it suitable for a large number of applications.
Its sustainable features including biodegradability and compostability, make PureBarrier a good alternative to non-renewable oxygen barrier packaging.
PureBarrier is produced from responsibly sourced and renewable wood pulp, certified according to Forest Stewardship Council standards and is biodegradable and certified compostable with OK Compost/ OK Compost Home from TÜV.
Already commercialized as coffee capsule lids and brewing materials for espresso systems, PureBarrier is currently being evaluated in many other nonfood applications such as health & beauty products.
