For a summer picnic, an individual pack makes the calories in one serving easier to judge, but compare its weight and calories per 100g before treating it as a lower-calorie product. Walkers lists 78 kcal and 0.45g salt for an 18g French Fries potato-snack pack, against 132 kcal and 0.17g salt for a 25g Lightly Salted potato-crisp bag; the choice changes if salt or conventional sliced crisps matter more. With a sharing bag, decide the serving size before opening it, and check the current pack’s allergen information for your guests.
A sealed pack gives you a defined amount to bring or hand out. Compare its total calories and weight with the amount you expect each person to eat; the NHS notes that a manufacturer’s stated portion may differ from yours.
Pack calories alone will not settle this choice. Walkers lists 0.17g salt in a 25g Lightly Salted crisp bag and 0.45g in an 18g French Fries potato-snack pack, despite the French Fries pack having fewer calories.
Check the exact pack’s ingredients, dietary-suitability claims and precautionary allergen wording before sharing it with guests. A vegan or gluten-free claim does not replace an allergen check; the Food Standards Agency explains that a ‘may contain’ statement signals possible unintended allergen presence.
Start with the amount each person is likely to eat, then compare salt and any dietary requirements. A sharing bag needs a serving decision as well as a look at its nutrition panel.
| Priority | What to check | Your needs |
|---|---|---|
| Serving size | Check kcal per pack, the pack weight and kcal per 100g. For a sharing bag, check how many grams the stated serving represents; the NHS notes that this may differ from the portion you eat. | I want to know the calories in the amount I plan to bring or serve, not just the figure printed beside a smaller portion. |
| Salt | Compare salt per pack and per 100g alongside calories. Walkers lists 0.45g salt in an 18g French Fries pack and 0.17g in a 25g Lightly Salted crisp bag. | If salt matters to my picnic choice too, the pack with fewer calories is not necessarily the one I want. |
| Dietary suitability | Read the exact product’s ingredients, vegan or gluten-free claim where relevant, and any ‘may contain’ statement. The Food Standards Agency says precautionary wording communicates possible unintended allergen presence. | I need to check what each guest can have before putting crisps out for everyone. |
| Pack format and storage | Check whether portions are individually sealed or come from one sharing bag. Follow the current pack’s storage directions; Joybuy’s listing for Walkers Lightly Salted specifies cool, dry storage away from direct sunlight and keeping inner bags sealed until needed. | Individual bags would let me hand out defined portions, while a sharing bag means deciding how much to serve and keeping the rest closed. |
Walkers French Fries lists 78 kcal for an 18g pack, while the other crisp packs discussed here contain different amounts. Pack totals describe the pack, not an equal weight of food.
Use kcal per pack to plan what someone will eat, then kcal per 100g to compare products at the same weight.
Walkers French Fries has fewer calories per pack than Walkers Lightly Salted, but Walkers’ product information lists more salt in its 18g pack than in the 25g Lightly Salted bag.
If both figures matter, read salt per pack and per 100g before choosing.
Tyrrells states five 30g servings in its 150g Lightly Sea Salted bag. Serving straight from the bag makes it harder to tell how closely each portion matches that stated amount.
Decide on portions before the picnic, or choose sealed individual packs if a defined serving is more useful.
A vegan or gluten-free claim addresses that stated suitability, not every guest’s allergy. The Food Standards Agency explains that ‘may contain’ wording concerns possible unintended allergen presence.
Ask guests about relevant requirements and read the ingredients and precautionary statement on the exact pack you will serve.
These product examples show why flavour, pack size and nutrition panel matter more to this picnic decision than a brand name alone.
Its Lightly Salted potato crisps and French Fries potato snacks offer different individual-pack choices.
Lightly Sea Salted is a potato crisp sold in formats that call for different portion calculations.

Sea Salted is a potato crisp labelled gluten-free and suitable for vegetarians and vegans.
Anglesey Sea Salt is a potato crisp labelled gluten-free and suitable for vegetarians and vegans.
These options include individual packs of Walkers crisps and an 85g PopChips sharing bag. Compare the portion you would serve from each; the sharing bag does not represent one individual serving.

The six 24g packs provide defined picnic portions. Walkers lists 128 kcal per 24g pack before the separate salt sachet is added; the sachet contains 0.60g salt, so the amount used changes the salt in the serving.

The six 25g bags provide individual picnic portions. Check this Mild Cheese & Onion variant’s own nutrition and allergen panel when comparing salt and calories; figures for Walkers Lightly Salted are not figures for this flavour.

The six 25g bags provide defined portions to take to a picnic. Compare this variant’s calories and salt on its own pack, and check its ingredients and allergen wording for guests with dietary requirements.

This 85g bag is an option to share at a picnic rather than an individually packed serving. Decide how much to serve and use the bag’s nutrition panel for that amount; check its ingredients and allergen statement before offering it to guests.
Use both: calories per bag show the total if you eat that bag, while calories per 100g allow a comparison at the same weight. The NHS notes that labels sometimes also give nutrition per portion, and that the manufacturer’s portion may not match yours.
Not in the Walkers examples here. Walkers lists 78 kcal and 0.45g salt per 18g French Fries potato-snack pack, compared with 132 kcal and 0.17g salt per 25g Lightly Salted potato-crisp bag. Compare both figures for the portion you expect to eat.
No. Read the exact pack’s ingredients and precautionary allergen statement for each guest’s requirements. The Food Standards Agency explains that ‘may contain’ wording communicates possible unintended presence of an allergen.
Follow the instructions on the pack you bring. Joybuy’s Walkers Lightly Salted listing specifies cool, dry storage away from direct sunlight and keeping the inner bags sealed until they are needed; also check the current pack’s best-before date.
