Yes — Cheese & Onion Flavour Potato Crisps is ultra-processed.
Classified as ultra-processed because the ingredient list includes industrial flavouring and refined isolated sugars. Specifically: “flavouring (contains milk)” is an added flavouring agent, and lactose is an isolated refined sugar; these are characteristic of NOVA ultra-processed products. The presence of cheese & onion seasoning blend and the ready-to-eat crisp format further support a UPF classification.
