Heinz is axing plastic wrapping on its multipacks of baked beans in the war against pollution.
The food giant is also ditching shrink wrap packaging from spaghetti and soup and will sell just single tins.
Tesco becomes the first supermarket to launch the wrapper free products. It is also removing plastic from all of its own label tinned food.
The move, starting in March, will save around 350 tons of plastic from being dumped in landfill sites or the sea.
Green groups welcomed the scheme and called on other firms and stores to follow suit.
Paula Chin, of conservation charity WWF, said: “We need to remove unnecessary single-use plastic wherever possible, to stop contamination of the world.
“If we want to protect nature we need more businesses to follow Tesco’s lead, before we run out of time to fight for our world.”
Kraft Heinz Northern Europe president Georgiana de Noronha added: “We’re excited to be partnering with Tesco on this.
“While we know we have more to do, this initiative is good news for the environment, and for the millions of people who enjoy Heinz varieties, as they’ll still be able to benefit from the same value for money multipacks provide.”
Tesco boss Dave Lewis said: “This is part of our plan to remove one billion pieces of plastic in 2020. But customers will still benefit from the same great value multipack price.”
Figures show shoppers buy 183,000 multipacks of tinned food at Tesco every day.
As part of the new scheme, the firm will also sell other products, including Green Giant sweetcorn, Princes and John West Tuna, in single cans only.
