The bags are made out of recyclable polyethylene and seafood waste and are treated with an antimicrobial agent that is claimed to protect from bacteria and mould.
Priced at 99p, the bags will be trialled from next week in more than 230 stores in parts of the East Midlands, Yorkshire, the North East, North West and South East of England.
If the trial is successful, the bags will be rolled out to all of Aldi’s 900 stores across the UK.
Chris McKenry, Plastics and Packaging Director at Aldi UK, said: “It’s more important than ever to strike a balance between reducing single-use plastic and maintaining food hygiene.
“Thanks to its antimicrobial qualities, this recyclable freezer bag enables us to continue on our mission to eradicate unnecessary non-recyclable materials while also offering customers a more hygienic way of storing and transporting food.”
