For an office snack where the calories in one ready-to-eat pack matter, compare sealed portions rather than assuming popcorn is low in calories. Tesco Groceries lists 44 kcal for a 10 g Propercorn Lightly Sea Salted pack; the sweet-and-salty multipacks listed by Sainsbury's and Tesco provide 68 and 71 kcal per 14 g pack respectively. A sharing bag can work if you measure a serving, but it does not provide the same built-in stopping point.
A sealed portion lets you use the figure for the whole pack rather than estimate how much you have taken from a larger bag. Tesco Groceries lists 44 kcal for each 10 g pack of Propercorn Lightly Sea Salted.
Individual packs offer a defined portion without giving up this flavour. The listed portions differ: Sainsbury's specifies 68 kcal per 14 g pack, Tesco 71 kcal per 14 g bag and Metcalfe's 78 kcal per 17 g pack.
Check the statement on the exact product, not an assumption about popcorn generally. The Propercorn Lightly Sea Salted, Tesco Sweet & Salted and Sainsbury's Sweet & Salty examples are labelled suitable for vegans; Propercorn also carries a milk-factory cross-contact statement.
Start with the amount you would eat at work, then compare the nutrition figures for that amount and the flavour you prefer.
| Priority | What to check | Your needs |
|---|---|---|
| Portion size | Check whether the calorie figure covers a sealed pack or a suggested serving from a larger bag. Compare the weight in grams as well as the calories. | I want to take one pack to my desk without measuring a serving. A sharing bag suits me only if I am willing to portion it out. |
| Sweet-and-salty flavour | Compare sugars and calories for the same declared portion. Sainsbury's lists 2.9 g sugars and 68 kcal per 14 g pack; Tesco lists 3.2 g sugars and 71 kcal per 14 g bag. | Sweet-and-salty flavour matters to me, but I still want to know what is in the pack I will finish. |
| Savoury flavour | Read the per-pack and per-100 g panels together. Tesco Groceries lists 44 kcal per 10 g pack and 439 kcal per 100 g for Propercorn Lightly Sea Salted. | I would choose a small sea-salted pack over a sweet variety, while keeping its small portion size in mind. |
| Dietary labels | Check the current ingredients, suitability statement and allergen warning on the exact variant. Propercorn Lightly Sea Salted carries a milk-factory cross-contact statement. | If I need to avoid an ingredient or cross-contact, the label on the product I receive matters more than the flavour name. |
Tesco Groceries lists 44 kcal for a 10 g Propercorn pack, but 439 kcal for 100 g of the same product. The pack figure describes a small portion, not the energy content of a larger amount.
Use calories per pack for the snack you plan to eat, and per 100 g when comparing products on the same weight basis.
ASDA lists 118 kcal for a suggested 25 g serving of its 100 g Sweet & Salted Popcorn bag, which it describes as four servings.
If you choose a sharing bag for work, measure a serving into a separate bowl or container before eating.
Sweet-and-salty packs have their own sugar and salt figures. For example, Sainsbury's lists 2.9 g sugars and 0.19 g salt per 14 g pack, while Tesco lists 3.2 g sugars and 0.17 g salt per 14 g bag.
Choose the flavour you want, then compare the figures for the exact pack size rather than applying one variety's label to another.
Ingredients and allergen statements matter particularly when popcorn is bought for someone with a dietary requirement or kept in a shared office.
Read the current pack before serving it, including any cross-contact or unpopped-kernel warning.
Its Lightly Sea Salted 6 x 10 g multipack offers a sealed savoury portion for a desk break.
The Sweet & Salt 6 x 17 g multipack is an individually packed sweet-and-salty option.

Its Sweet & Salty Butterfly Popcorn 6 x 14 g provides individually packed portions.
Its Sweet & Salted Popcorn comes in a 100 g sharing bag rather than sealed single portions.
Tyrrells describes Sea Salted Caramel, Madagascan Vanilla and Sea Salt popcorn flavours in its range.

Compare this larger pack size with the 12 g Butterkist varieties, and check the toffee variant's current ingredients if you avoid milk.
A small pack can contain fewer calories than a larger amount of the same popcorn, so check the weight behind the figure. Tesco Groceries lists 44 kcal per 10 g pack for Propercorn Lightly Sea Salted, alongside 439 kcal per 100 g; those figures answer different questions.
Use per 100 g to compare equal weights, then use the per-pack or declared-serving figure to plan one office break. GOV.UK's nutrition-labelling guidance explains the per-100 g presentation; for a sharing bag, check how much of that bag the stated serving represents.
A sealed multipack gives you a defined pack to open, while a sharing bag needs measuring if you want to follow its serving figure. ASDA suggests four 25 g servings for its 100 g Sweet & Salted Popcorn bag, so portion one out before eating if that is the amount you intend.
Read the current product's ingredients, allergen and safety warnings before sharing it. Propercorn Lightly Sea Salted carries a milk-factory cross-contact statement, and Sainsbury's warns that its Sweet & Salty Butterfly Popcorn may contain unpopped kernels.
