UK-based flexible packaging company Parkside has partnered with supermarket chain Iceland to develop recyclable paper packaging for frozen food.
The recyclable pouch features enhanced capabilities such as heat saleability, as well as a range of water-based coatings with high barrier performance to withstand the freezer environment for long periods of time.
In addition, the grease and oil-resistant packaging offers sustainable properties as it can break down when re-pulped in the paper recycling process.
Parkside sales account manager Mark Shaw said: “It has been a huge privilege for us to work on this project with Mark and his team.
“Until recently, achieving a high level of grease and oil resistance and heat seal ability for frozen food has been extremely challenging.
“Typically, a plastic layer such as Polyethylene 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 new packaging is designed for Iceland’s Northcoast range of frozen seafood.
The heat-sealable paper solution will replace the low-density polyethylene (LDPE) bags previously used for Northcoast products.
Iceland packaging specialist Mark Armstrong said: “As everyone knows, we are loud and proud about our forward-thinking ideas and commitment to plastic-free packaging across our products.
“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.”
In February this year, Parkside extended its collaboration with independent tea company Bird & Blend by creating larger loose tea pouch and pyramid teabag collections.
