People packing an individual lunch side
A sealed bag can go alongside a sandwich or salad without portioning crisps from a sharing pack. Check the weight: the individual bags considered here range from 25g to 40g.
Who is choosing these crisps?
Shoppers checking dietary suitability
Ingredients and allergen statements differ between flavours, even within a brand. Read the label for the exact bag you intend to pack, including any vegan or gluten-free declaration you rely on.
People choosing how large a snack to pack
A 25g bag and a 40g bag serve different portion preferences. Compare the weight and per-bag nutrition information rather than treating “grab bag” as a fixed size.
What should you check first?
Start with the amount you want to pack, then compare the label of the particular flavour and bag size. A different recipe or portion can change the relevant ingredients and per-bag figures.
| Priority | What to check | Your needs |
|---|---|---|
| Bag size | Read the grams per individual bag and the number of bags in the pack. Walkers Ready Salted is listed at 25g per bag; Seabrook Sea Salted at 31.8g and Tyrrells Lightly Sea Salted at 40g. | I want a sealed side for lunch, or a larger single bag to eat as a snack. The pack weight helps me tell the two apart. |
| Ingredients and allergens | Check the exact flavour’s ingredients, highlighted allergens and any “may contain” statement. Look for an explicit vegan or gluten-free declaration if it matters to your choice. | A familiar brand or plain-sounding flavour is not enough for me to judge whether the particular bag meets my dietary requirements. |
| Nutrition panel | Compare figures for the portion you will eat, as well as per 100g where useful. Walkers UK lists 130 kcal and 0.34g salt per 25g Ready Salted bag; Tyrrells lists 208 kcal and 0.26g salt per 40g Lightly Sea Salted pack. | When I change bag size or try a lentil crisp, I want to compare the stated serving and its energy, fat and salt rather than rely on the snack’s name. |
| Flavour | Read the full recipe for seasoned varieties. McCoy’s lists barley malt vinegar extract in Salt & Malt Vinegar and milk ingredients in Flame Grilled Steak; those declarations apply to those flavours. | I might prefer a seasoned crisp, but I need to check that flavour’s ingredients instead of carrying over assumptions from a plain salted one. |
| Pack quantity | Count the individual portions and check whether the pack contains one flavour or several. REAL Sea Salt’s official shop format is a case of 24 × 35g bags. | For regular packed lunches, I can decide whether repeated bags of one flavour suit my routine and storage space. |
Common buying mistakes
-
Treating “grab bag” as a standard portion
Individual bags in this selection of product examples run from 25g to 40g. Walkers UK lists 130 kcal for its 25g Ready Salted bag, while Tyrrells lists 208 kcal for its 40g Lightly Sea Salted pack; the flavours and bag weights differ.
Compare grams and the per-bag panel to decide whether the bag is the small side or larger snack you want.
-
Assuming a plain flavour is suitable for every allergy
An ingredient list and a manufacturer’s cross-contact statement answer different questions. A plain-sounding recipe may still carry a “may contain” warning, and another flavour from the same brand may have different ingredients.
Read the current label on the exact flavour and pack size; follow the advice you have been given for your allergy.
-
Reading a lentil-crisp comparison as a general verdict
Tyrrells states a lower-fat comparison for its lentil crisps, but its Sour Cream & Onion product also lists 0.60g salt per 30g serving and contains milk ingredients. One comparison does not describe every part of the recipe.
Compare the chosen flavour’s serving size, fat, salt and allergens with the potato crisps you would otherwise pack.
-
Buying a case without checking the format
REAL Sea Salt is listed by its official shop as 24 bags of 35g. A case commits you to that bag size and flavour for multiple lunches.
Check the bag count, storage space, best-before details and current delivery options before ordering.
Brand and product references
These examples show why it helps to compare particular flavours and formats, rather than treating every product from a brand alike.
Walkers
Walkers UK lists its Ready Salted crisps as a 25g portion with 130 kcal per bag.
- The listed recipe is potatoes, vegetable oils and salt.
- Check the pack’s allergen and factory-handling statements if cross-contact matters to you.
Tyrrells
Its Lightly Sea Salted potato crisps include a 40g, one-serving pack; its lentil crisps offer a different recipe to compare.
- Tyrrells lists 208 kcal and 0.26g salt for the 40g Lightly Sea Salted pack.
- Lightly Sea Salted may contain milk. Sour Cream & Onion Lentil Crisps contain milk ingredients, so check each flavour separately.
Kettle Chips
Kettle Chips describes its Lightly Salted product as hand-cooked using British potatoes.
- The brand labels that product gluten-free and suitable for vegans and vegetarians.
- Confirm the individual bag format if you need a single portion for lunch; those product declarations should not be assumed for other flavours.
Seabrook
Seabrook lists a 31.8g Sea Salted bag with 164 kcal and 0.4g salt per bag.
- The brand labels this Sea Salted product gluten-free and suitable for vegetarians and vegans.
- Use those figures and suitability statements for the specified Sea Salted product, not every Seabrook flavour.
McCoy's
McCoy’s ridged crisps include seasoned flavours with different ingredient and allergen declarations.
- The Salt & Malt Vinegar product page states 2.1g salt per 100g, giving a figure to compare with another flavour’s label.
- That flavour lists barley malt vinegar extract; Flame Grilled Steak lists milk ingredients. Check the chosen pack rather than transferring either recipe to another variant.
REAL Hand Cooked Crisps
REAL Sea Salt is listed by the brand’s official shop in a case of 24 × 35g bags.
- Its listed ingredients are potatoes, vegetable oils and sea salt.
- Consider whether a case of one flavour and bag size fits your packed-lunch plans.
Joybuy options for packed lunches
These options include compact multipacks and a larger 40g portion. Pringles Sour Cream & Onion is a different product and format from the hand-cooked 40g bag discussed above, so compare its own label rather than applying Tyrrells’ figures to it.

Walkers Ready Salted Crisps 6 × 25g
Six individual 25g bags provide a compact crisp side for packed lunches. Walkers UK lists 130 kcal per 25g Ready Salted bag; check the current pack’s allergen statement before choosing it for someone with an allergy.
No image available
Walkers Salt & Shake Crisps 6 × 24g
Six 24g bags offer another compact portion for a lunchbox. Salt & Shake uses a separate salt sachet; check the pack’s directions and allergen statement for this variant.
No image available
Walkers Ready Salted Crisps 12 × 25g
This pack keeps the individual Ready Salted bag size at 25g but contains twelve bags rather than six. It may suit a routine of packing lunches regularly; check the current allergen information on the pack.
No image available
Pringles Sour Cream & Onion Crisps 40g × 12
The listed 40g portions are larger than the 24g and 25g options here and have a sour-cream-and-onion flavour. Check this product’s own ingredient, allergen and nutrition panels; figures for other 40g crisps do not describe Pringles.
No image available
McCoy's Ridge Cut Mighty Meaty 6 × 25g
Six individual 25g bags combine a compact portion with the Mighty Meaty flavour selection. If ingredients or allergens affect your choice, check each included flavour’s bag rather than relying on the label of a different McCoy’s product.
Frequently asked questions
What size crisp bag works for an office packed lunch?
Choose by the portion you want, not the term “grab bag”. A 25g bag is a compact side; examples from Seabrook, REAL and Tyrrells show single bags or portions of 31.8g, 35g and 40g if you want a larger amount.
Are plain salted crisps automatically suitable for vegan, gluten-free or allergen-sensitive diets?
No: check the exact product’s declarations and allergen statement. Seabrook labels its Sea Salted product gluten-free and suitable for vegans and vegetarians, while Tyrrells says its Lightly Sea Salted product may contain milk.
Should I read the ingredients if I have a food allergy?
Yes. Read the current ingredients and allergen information for the exact flavour and pack, including any cross-contact warning, and follow the advice you have been given for your allergy. A brand name or familiar flavour is not a substitute for that check.
Does choosing lentil crisps settle the fat comparison?
No. Tyrrells makes a lower-fat comparison for its lentil crisps, but that brand comparison does not describe every alternative you might buy. Compare the fat per 100g and per serving on the chosen packs, along with salt and ingredients; its Sour Cream & Onion lentil flavour contains milk.
What matters when buying crisps by the case?
Check the number and size of individual bags, flavour, storage space and best-before details. REAL Sea Salt, for example, is listed by its official shop as a case of 24 × 35g bags, so consider whether that quantity of one flavour fits your lunch routine.
