Boosting recyclability in the freezer section
Parkside Flexibles has produced a paper recyclable frozen food packaging option for UK supermarket Iceland, which is using the packets for its Northcoast range of frozen seafood.
The supermarket chain had previously used an LDPE-plastic bag that could not be properly recycled. The new version uses a specially developed paper pouch that is grease and oil resistant and is designed to be suitable for freezer temperatures.
Typically, a laminate of paper with a thin plastic layer is used for this kind of frozen food where oil is inherent to the product. This offers protection against leaks but a major downside is that it complicates the recyclability of the packs.
The heat-sealable paper solution was designed to withstand the rigours of frost and moisture in a freezer environment, for prolonged periods of time. This has been achieved by creating excellent heat sealability, and by using a range of water-based coatings with high barrier performance, which are designed to break down when re-pulped in the paper recycling process.
Mark Armstrong, Packaging Specialist at Iceland, said: “As everyone knows, we are loud and proud about our forward-thinking ideas and commitment to plastic-free packaging across our products. We previously worked with Parkside in a successful bid to reduce food waste via a lidding film solution in 2017.
“But we know we can do more. As consumer sentiment continues to grow for circular solutions, it is the perfect time to collaborate once again in a bid to reduce unnecessary plastic in our packaging.
“Bag sealing was a challenge, as was ensuring the material had the necessary barrier properties. We also wanted the print to match the existing LDPE bag and therefore a lot of time was spent in artwork and repro to give us the best possible result.”
