The trial pack is widely recyclable and will replace plastic outer wrapping on more than 300,000 six-pack multipacks, across Sea Salt and Cheese and Onion flavours.
The packs launched across 800 Tesco stores on 1 March, with the food company asking shoppers for feedback on the new design and its functionality.
“With this latest trial, people can buy a selection of Walkers Baked multipacks in paper-based outer packaging that can be easily and widely recycled with regular recycling at home,” Walkers senior marketing manager, Rachael Smith said.
