One-day lunch packers
An individual bag lets you take a stated portion with one lecture-day lunch. Check its weight rather than assuming a grab bag and a sharing bag contain similar amounts.
Who is choosing?
Repeat lunch packers
If you pack lunch on several days, compare multipacks and cases by both inner-bag count and weight. A larger pack means more bags to store, not necessarily a better choice for your routine.
Ingredient-conscious snackers
Choose by the exact flavour’s ingredients, allergen warnings and nutrition declaration, rather than relying on what another flavour from the same brand contains.
What should you check?
Start with the bag you would carry to lunch; then decide whether buying several of those bags suits your plans.
| Priority | What to check | Your needs |
|---|---|---|
| Bag size and count | Read the net weight of each inner bag and the number of bags, not just the total pack weight. For example, REAL Hand Cooked Crisps lists its Sea Salt case as 24 × 35g. | For one lunch, I want to know how much is in the bag I will carry. If I am packing several lunches, I also need to know how many bags I am buying. |
| Flavour and style | Check the named flavour and its ingredients. Descriptions such as crinkle-cut or ridged identify a style, but do not establish which texture you will prefer. | I would rather choose a flavour I want to eat than assume that every bag from a familiar brand tastes alike. |
| Nutrition per bag | Check the weight alongside the per-bag declaration. Tyrrells declares 0.26g salt for its 40g Lightly Sea Salted bag; Seabrook declares 0.4g for its 31.8g Sea Salted bag. Use per-100g figures when comparing products on the same weight basis. | If I eat the whole bag, I want its per-bag figures. Different bag sizes also matter when I compare the two declarations. |
| Ingredients and allergens | Read the current information for the exact flavour, including precautionary warnings. Tyrrells says its Lightly Sea Salted crisps may contain milk; McCoy’s lists milk ingredients for Flame Grilled Steak flavour. | An ingredient may matter to me, so I need to check the particular bag I am buying rather than rely on its brand name or another flavour’s label. |
Common buying mistakes
-
Taking a case weight for a single-bag portion
A case of individual bags and one larger bag answer different lunch needs. Kettle Chips lists an 18 × 40g case, while REAL Hand Cooked Crisps lists a 24 × 35g Sea Salt case.
Check both the inner-bag weight and bag count before ordering.
A full case leaves you with unopened bags to store after a one-off lunch.
-
Comparing salt per bag without checking weight
Per-bag figures describe the amount in each product’s stated portion. Tyrrells’ Lightly Sea Salted bag is 40g, while Seabrook’s Sea Salted bag is 31.8g.
Use per-bag figures for the portion you plan to eat, and per-100g figures for a comparison on the same weight basis.

Assuming a brand or vegan label resolves an allergy question
Warnings and ingredients can differ by flavour. The Food Standards Agency advises that vegan labelling is not a substitute for allergen labelling.
Check the exact product’s current ingredients and precautionary warnings, including those on the bag you receive.
Brand and product references
These examples show why the exact flavour and pack format matter; a detail stated for one product does not necessarily apply across its brand’s range.
Walkers
Ready Salted is a reference point for a familiar potato-crisp flavour.
- Walkers lists potatoes, vegetable oils and salt as ingredients for Ready Salted.
- Its Ready Salted information includes a factory-handling warning; check the particular bag for current allergen advice.
Tyrrells
Lightly Sea Salted is listed in a 40g pack, giving one stated bag size to compare.
- Tyrrells declares 0.26g salt per 40g Lightly Sea Salted pack.
- That variant carries a may-contain-milk warning; its figures should not be applied to other flavours or pack sizes.
Kettle Chips
Kettle Chips lists cases of individual 40g bags for shoppers planning several lunches.
- Its listed case format contains 18 × 40g bags.
- Check whether you want that many bags and confirm the details of the flavour you choose.
Seabrook
Seabrook describes its crisps as crinkle-cut and provides a per-bag declaration for Sea Salted.
- Seabrook declares 0.4g salt per 31.8g Sea Salted bag and describes that variant as gluten-free and suitable for vegans.
- Those dietary descriptions concern Sea Salted, not every Seabrook flavour.
McCoy's
McCoy's is a ridged-crisp option when cut and seasoning are part of your choice.
- The brand describes its crisps as ridged.
- Its Flame Grilled Steak flavour lists milk ingredients; check allergens for the exact flavour you choose.
Real Crisps
REAL Hand Cooked Crisps lists Sea Salt in a case of individual bags.
- The brand specifies 24 × 35g for its Sea Salt case.
- A case requires buying more than you need for a single lunch.

Questions about lunch bags
Is a bag of crisps enough for lunch?
Treat crisps as part of lunch rather than the whole meal. The NHS Eatwell Guide says that balance can be considered across a day or week and advises eating foods high in fat or salt less often and in small amounts.
How can I compare bags of different sizes?
Start with each bag’s net weight and the basis of its nutrition declaration. Per-bag figures describe the whole stated portion; per-100g figures let you compare products on the same weight basis.
Can I rely on a vegan description if I have a food allergy?
No. The Food Standards Agency advises that vegan labelling is not a substitute for allergen labelling. Check the exact product’s allergen information when ordering and the packaging you receive; UK Food Standards Agency guidance says distance sellers must provide allergen information before purchase and at delivery.
What matters when buying a case for several lunches?
Check the number and weight of its inner bags, its storage directions and its best-before marking. That tells you what you can pack each day and whether the case suits your plans; a best-before date concerns quality and is not interchangeable with a use-by date, as the Food Standards Agency explains.
