The 80g bags will help retailers drive incremental sales among “thrifty shoppers seeking sharing snacks which represent good value”.
The format joins the existing Flipz Milk Chocolate price-marked pack, which Pladis said is already worth £400,000 in the convenience channel.
Jonathan Bull, marketing director at Pladis, said: “Flipz Peanut Butter, the latest price-marked pack to join our Flipz line-up, reflects the important role we know price-marked packs play in driving impulse sales in convenience.
“Despite accounting for only 12% of products, price-marked packs represent an incredible three-quarters of sales in this channel.
“Couple this with the fact that 91% of shoppers are actively looking to save on groceries and it is clear that products in this format are independent retailers’ ticket to unlocking snacking sales growth.
“As a nation, we have all become accustomed to celebrating moments of togetherness, such as evenings in, and – even as we emerge out of lockdown – sharing snacks like Flipz continue to form an integral part of reunions with friends and family, with volume growth up 12% year on year.
“We are really proud of the fact Flipz has become one of the biggest snack brands to launch in the UK over the past five years – and this is a brand which really resonates with the convenience shopper.
“Sales are up 106% in independents as we continue to drive appeal for younger adults.”
