For a small, ready-to-eat portion, Propercorn Lightly Sea Salted has 44 kcal in a 10g bag, according to Ocado; its size matters if you expect to eat more during a film. For a sweet individual bag, ASDA lists Butterkist Sweet at 61 kcal per 12g pack, while Tesco lists Propercorn Sweet & Salty at 65 kcal per 14g pack. A sharing bag gives you more flexibility, but check the serving size: ASDA lists 150 kcal per 30g serving for Butterkist Sweet & Salty, with three to four servings in its 100g bag.
An individual pack gives you the calories for the whole bag without having to estimate a portion from an open sharing pack. The reviewed 10g, 12g and 14g packs differ in both size and calories, so compare the amount you would actually eat.
Sweet and sweet-and-salty multipacks offer individually wrapped portions. Check sugars and fat alongside calories: ASDA’s Butterkist Sweet listing shows high traffic-light indicators for both fat and sugars in its 12g pack.
A sharing bag can work when several people will divide it into servings. ASDA lists three to four servings in a 100g Butterkist Sweet & Salty bag, rather than treating the bag as one serving.
Start with the portion you plan to eat, then compare its nutrition information with other packs of a similar size.
| Priority | What to check | Your needs |
|---|---|---|
| Portion size | Compare kcal per individual pack or labelled serving, as well as per 100g. Check how many servings a sharing bag contains. | I would rather open one small bag than measure popcorn from a larger one. If we are sharing, I can divide the bag before the film. |
| Nutrition label | Compare sugars, fat, saturates and salt on the same serving basis. The Food Standards Agency explains that traffic-light colours identify low, medium and high levels of the labelled nutrients. | Calories are only part of my choice; I also want to see the sugar and fat information. In a 2024 Northern Ireland survey of 611 adults by the Food Standards Agency and Ipsos, 49% said they actively used traffic-light labelling when shopping for food; that figure concerns food shopping generally, not popcorn. |
| Flavour and pack size | Check whether a sweet, sweet-and-salty or salted option comes in the portion size you want. Do not compare the calories of different-sized packs without noting their weights. | A sweet flavour matters to me, but I still want to know how much popcorn is in the bag I will open. |
| Ingredients and warnings | Read the current pack’s ingredients, allergen statement and any warning about unpopped kernels. Check the exact variant rather than relying on another flavour’s label. | I need to check whether the snack meets our dietary requirements and read any warnings before serving it. |
