Sustainable and flexible packaging solutions specialist, Parkside, has collaborated with British supermarket chain Iceland to deliver one of the world’s first paper recyclable packaging solutions for frozen food.
The new sustainable packaging has been designed for the supermarket’s Northcoast range of frozen seafood.
The packaging solution is seen as a significant milestone for Iceland in its pursuit of plastic-free packaging, as well as for frozen food sector, as it represents one of the first successful applications of paper flexible packaging for frozen food.
“As everyone knows, we are loud and proud about our forward-thinking ideas and commitment to plastic-free packaging across our products,” said Mark Armstrong, packaging specialist at Iceland.
“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.”
Iceland’s Northcoast products were previously packed in an LDPE bag, but following the project with Parkside, they are now packed in a specially developed recyclable paper pouch with excellent grease and oil resistance.
“Until recently, achieving a high level of grease and oil resistance and heat seal ability for frozen food has been extremely challenging,” said Mark Shaw, sales account manager at Parkside.
“Typically, a plastic layer would need to be extruded or laminated to the paper, which would then need to be removed when recycling post-consumer use.
“Our leading technology removes the need for the plastic, and gives a truly recyclable paper solution with the added benefit of high barrier functionality.”
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 utilising a range of water-based coatings with high barrier performance, which are designed to break down when re-pulped in the paper recycling process.
“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,” Armstrong concluded.
