Green boost: combining barrier with recyclability
Manufacturers of barrier packaging are using a variety of methods to maintain packaging performance while making their products more recyclable
Manufacturers of plastics products are under increasing pressure to improve the recyclability of their products. This can be notoriously difficult in barrier packaging, where the use of several materials boost barrier performance but makes recycling almost impossible. Packaging group Mondi has teamed up with
Reckitt Benckiser (RB) to launch recyclable, mono- material flexible plastic packaging for its Finish dishwasher tablets Quantum Ultimate. This product had previously used a multilayer, PET/PE laminate pouch construction that was not recyclable. With RB’s commitment to make 100% of its plastic packaging reusable or recyclable by 2025, this had to change. “We worked closely with RB to find the best solution and make this product fully recyclable without sacrificing the high-end look, feel and performance,” said Olivier Seux, global key account manager at Mondi Consumer Flexibles. “We asked questions about the entire process and tailored various aspects to meet the customer’s precise needs.” The packaging uses Mondi’s BarrierPack
Recyclable, which combines a high oxygen and moisture barrier with ease of recyclability. “It was vital that the stand-up pouch was rigid enough with a smooth appearance, while offering exact colour matching and a quality feel,” said Seux. “There could be no compromise in the

barrier properties of the package, and it also needed to incorporate a recyclable zipper for ease of use in opening and closing the pouch.” RB plans to roll out its new Finish packaging in
Italy from May, followed by Germany and the UK, and then a global launch. In similar fashion, BarrierPack Recyclable helped
Yarrah Organic Petfood to develop more sustain- able packaging for its brands. Yarrah wanted to introduce a fully recyclable pouch to replace a multilayer laminate packaging — which was difficult to recycle — to keep it in a circular economy. The pouch also needed to be resealable to keep pet food and snacks fresh, while adding convenience for pet owners.
Healthy snack Innovia Films has helped to produce a recyclable pack for German snack manufacturer Wildcorn’s organic popcorn range. The joint project to establish a new sustainable
packaging standard began soon after the launch of Innovia’s Propafilm Strata high barrier film, which achieved the ‘Made for Recycling’ logo from Interseroh, a German recycling and consulting company. “This certification proves the recyclability of our
new Strata BOPP film,” said Alasdair McEwen, global product manager for packaging at Innovia Films. “It has been designed as a standalone mono
