The promotional packs feature images of Spider-Man and offer shoppers the opportunity to win prizes with purchases of Butterkist popcorn.
Butterkist buyers can win one of five Sony tech bundles that include a Sony Bravia 65” smart TV, a Sony All-One Sound Bar and Sony headphones.
The film is set to be released exclusively in cinemas on 17 December 2021.
Kevin McNair, marketing director at brand owner KP Snacks, said: “The new Butterkist promotion aims to capitalise on the growth of popcorn sharing occasions, which are up by 21%.
“The promotion is perfectly positioned to disrupt shoppers, broaden Butterkist’s appeal and bring new shoppers to the category.
“Driving category penetration by focusing on the fun and excitement of a big theatrical release, a well-loved character and the opportunity to win big prizes, the campaign creates a valuable opportunity for retailers to drive growth in popcorn.”
Running from November 2021 until mid-February 2022, the new promotional packs will be available across sharing bags of Tasty Sweet (100g), Deliciously Sweet & Salty (100g), Simply Salted (80g) and Crunchy Toffee popcorn (170g).
The campaign will also run across these four flavours in £1 PMP format.
McNair added: “We are proud to team up with Sony Pictures on an immensely successful film franchise to drive further penetration in the popcorn category.”
