Marks & Spencer has switched from plastic to paper packaging for a range of clothing items.
The retail giant said the move included men’s socks and woven pyjama sets as well as 40 per cent of male underwear lines.
It said the decision removed more than 5 million units of plastic from the business over the next year.
Marks & Spencer added that it planned to use recyclable paper packaging more widely within its men’s essentials range if trials were successful.
Katharine Beacham, head of sustainability in the Clothing & Home department, said: “We know we have a responsibility to do the right thing when it comes to our packaging by reducing unnecessary plastic.
“This one small change to our men’s essentials range will make a huge difference by removing over 5 million units of plastic from our supply chain.
“It also gives our customers the confidence to make more sustainable choices more easily when they shop with us, and trust that the M&S quality products they love are made, sourced and packaged with care.”
Marks & Spencer last year teamed up with Polytag to track its plastic waste.
