In contrast to composite packaging options that mix two or extra materials sorts (suppose aluminum-lined paper-based wrapping for brie, or the multi-layer movie on sliced cheese packs), mono-material-based packaging has just about zero boundaries to recycling. It’s because it’s product of a single materials, so recyclers don’t must separate the liner from the paperboard, for instance.
Packaging producer Mondi has just lately give you a mono-material polypropylene-based packaging that gives excessive oxygen and water vapor barrier to make sure freshness. Comprising mono-material base, internet and lidding movie product of polypropylene (PP), the packaging is produced and printed by Mondi earlier than being transformed for 1kg and 2kg blocks of Hushållsost cheese made by Skånemejerier and offered as a private-label product by Swedish grocery store ICA. Nevertheless, the packaging is appropriate for a variety of onerous and semi-soft cheeses, or different food-grade purposes, we have been informed.
“This resolution may very well be used for any cheese or different purposes, roughly,” defined Helene Brynell, Regional Gross sales Nordic Shopper Flexibles at Mondi. “It could be really useful to vary the thickness or different particulars within the formulation relying on, for instance, barrier wants, form of the product and manufacturing machines. However a mono PP is appropriate for a lot of totally different purposes within the meals trade and non-food trade. That’s what makes it so implausible.”
The problem for Mondi was to develop a mono-material packaging that might correctly defend the product inside, offering appropriate barrier properties towards oxygen and water vapors to maintain the cheese recent on the shelf. “The packaging has to guard the product whereas providing a extra sustainable resolution,” Brynell mentioned. “By the mono-material construction the packaging is designed for recycling, aiming to maintain the packaging supplies in circulation.”
The plastic beforehand used for this cheese had beforehand been non-recyclable, a Skånemejerier spokesperson confirmed for DairyReporter.

We’ve sturdy, efficient and handsome packaging that retains supplies within the loop and responds to shopper calls for for extra sustainable options.”
The discharge of the brand new packaging coincides with the opening of a brand new recycling facility, Web site Zero, the place used plastic from throughout each Sweden and Finland will probably be processed. Brynell defined: “Because of the mono-material design, Web site Zero will be capable of successfully kind the answer for recycling, working in direction of a round financial system.”
Rickard Jansson, Improvement Engineer at Swedish Plastic Recyclin, added: “We’re very optimistic in regards to the new packaging that Mondi has developed along with Skånemejerier for ICA. By utilizing mono-material movie as a substitute of laminate consisting of various kinds of plastic, we are able to kind out and recycle the packaging that’s left within the system, thus avoiding incineration. With Web site Zero’s new expertise, this PP film-based packaging will be capable of develop into new merchandise, which has not been potential in any facility in Sweden earlier than.
