The new packaging will be widely available in stores from 11 September 2021.
The move has been made with the aim to see “180 tonnes of plastic removed from the environment every single year”.
It comes after Mars Petcare announced in July a recycling programme with Pets at Home which saw dedicated in-store recycling points for pet food packaging introduced across 40 UK stores.
The new packaging is made from cardboard, and “now fully recyclable, removing 15 million individual pieces of plastic annually”.
Kim Smet, interim general manager at Mars Petcare, said: “The switch from shrink-wrap to cardboard is an important step in helping us achieve our goal of 100% recyclable packaging by 2025.
“We know that over the past year alone the UK’s pet population has sky-rocketed to an all-time high, tipping 20m dogs and cats – nearly a third of the size of the UK human population, so as an industry our sustainability efforts must reflect this and improve, at speed, to create the world we want tomorrow.”
Additional changes in 2021 saw Pedigree Schmackos packaging reduced by 12%, while all Dreamies 60g packs became thinner, leading to a combined 27.6 tonnes of virgin plastic saved in the UK.
Further to this, Mars Petcare joined Asda in their trial of in-store refill zones and provided the first pet care offering with products from popular Mars brands, Whiskas and Pedigree.
