It has since joined the Flexible Plastic Fund initiative and rolled out recycling points in even more stores.
Customers can bring hard to recycle items to 271 stores meaning fewer products will end up in landfills.
All flexible plastics can be returned, including laminates and pouches.
The retailer also listed products which can be recycled at more than 500 branches in the country.
What can be recycled?
Dry food flexible packaging
This includes bread, cereal, rice and dry food bags, confectionery, biscuit and cake wrappers and crisp and snack packets.
Other food flexible packaging
Customers can return peelable film lids, fruit, vegetable and salad bags, flower wrapping, multipack film wrap, clingfilm and sleeves on bottles.
Pouches and sachets
This includes coffee, confectionery, home care, sauce pouches, pet food and microwave food pouches.
Non-food flexible plastic
Hard to recycle products such as carrier bags, clothing bags, bubble wrap, toilet roll and kitchen roll wrapping can all be returned.
Before returning products, they should be clean and free of food.
Sticky labels should also be removed where possible.
The updated recycling centres follow Sainsbury’s plans to reduce the use of plastic.
The retailer has stated it will reduce the use of plastic on its own brand and branded products by 50 percent by 2025.
Shoppers have praised some of the changes made by the supermarket giant.
Posting online, one wrote: “Hi @sainsburys Fab to see your roll out of soft plastic recycling at your stores.”
Another added: “Delighted – my local supermarket is on the list!”
One more simply commented on the scheme as being “great”.
