The firm has announced that it will switch to paper outer bags for all its Snack A Jacks rice cake multipacks in a move that will cut its use of virgin plastic substrates by 65 tonnes a year.

The switch will be rolled out next month and is part of its PepsiCo Positive initiative, which includes a target of reaching net zero emissions by 2040.

Just over a year ago PepsiCo began trialling paper-based outer packaging on its Walkers Baked savoury snacks.

Gareth Callan, PepsiCo UK and Ireland sustainable packaging lead, commented: “Our outer paper multibag packs are working well on Walkers Baked, giving us the confidence to roll out this format across more of our snacks brands.

“The new packaging will help further reduce our non-fossil plastic use, while also helping to lower our carbon footprint as we work towards our commitment to creating a world where packaging never becomes waste.”

At the end of last year the food and drink giant also rolled out new recycled plastic packaging for Walkers Sunbites.
