Choose an individually sealed bag if you want the amount in your midnight snack to be clear before you open it. Check the weight and nutrition for the whole bag: the examples here include 25g Walkers packs and a 40g Tyrrells pack, so a per-100g figure alone will not tell you what is in each snack. Flavour, salt and any allergen statement still need checking on the exact pack you choose.
An individual bag makes its contents easier to compare with the serving shown on the label. Walkers lists a typical 25g pack for Lightly Salted, while Tyrrells identifies its 40g Lightly Sea Salted pack as one serving.
If salt matters to your choice, compare the amount for the bag you intend to eat. Walkers UK lists 0.17g salt per typical 25g Lightly Salted pack and 0.34g per 25g Ready Salted pack; the products and their pack labels must not be treated as interchangeable.
Check the ingredients and precautionary statements on the exact flavour and pack. Seabrook labels its Sea Salted product gluten-free and suitable for vegans and vegetarians, but a plain-sounding flavour is not a substitute for reading its label.
Start with the size of the bag you would open, then compare its label with the flavour and ingredient information that matters to you.
| Priority | What to check | Your needs |
|---|---|---|
| Bag size | Check the weight, servings per bag and nutrition for the whole bag. Tyrrells identifies its 40g Lightly Sea Salted pack as one serving; Walkers lists a typical 25g Lightly Salted pack. | I would rather open one bag with a stated amount than judge how much I have eaten from a sharing bag. |
| Salt | Compare salt per bag as well as per 100g. Walkers UK lists 0.17g per typical 25g Lightly Salted pack and 0.34g per 25g Ready Salted pack. | If salt influences my choice, I want to know the amount in the bag I will actually open. |
| Flavour and ingredients | Read the exact variant’s ingredient list and per-bag figures. A plain salted pack and a seasoned pack need not have the same ingredients or nutrition. | Some nights I want a plain salted flavour; other times I would choose seasoning after checking the bag size and label. |
| Dietary labels and allergens | Check the current pack’s ingredients, allergen emphasis and any precautionary statement. Look for gluten-free or vegan wording on the particular product, not just the brand. | Where an ingredient or dietary label matters to me, I need to check the flavour I am buying rather than assume another pack has the same declaration. |
That comparison does not show the amount in differently sized bags. Walkers UK lists 132 kcal and 0.17g salt for a typical 25g Lightly Salted pack; Tyrrells identifies a 40g Lightly Sea Salted pack as one serving.
Check the bag weight and servings, then use the label’s per-bag figures when deciding how much you want to open.
A short ingredient list does not tell you whether a pack carries a precautionary allergen statement.
Read both the ingredients and any ‘may contain’ wording on the current packet if an allergen affects your choice.
Seabrook describes Sea Salted as gluten-free and suitable for vegans and vegetarians. That wording identifies the named product, not every flavour or pack format sold under the brand.
Confirm the wording on the particular bag you intend to eat.
A Joybuy listing titled Tyrrells Lightly Sea Salted includes marketing text naming Taylors Sea Salted. Mixed product names make that text a poor basis for deciding which ingredients or nutrition apply.
Confirm the product identity and use the current packet for the figures and declarations relevant to your choice.
These examples describe particular products and formats; a brand name alone does not establish the size or label of another bag.

These multipacks contain individually sized bags for a late snack, including salted, cheese-and-onion, baked and variety options. Check the inner pack’s label when comparing flavours or nutrition.

The 25g inner bags give you a stated size for one late snack. Check this Mild Cheese & Onion variant’s own salt and allergen declarations rather than using figures for another Walkers flavour.
No image available
The 22g inner bags offer a smaller stated pack size than the 25g options here. For a variety pack, check the flavour and allergen information on the individual bag you choose.

Each named inner bag is 23g, which may suit you if you want a defined cheese-and-onion snack. This is sold as a snack rather than identified here as a traditional potato crisp; check its ingredients if that distinction matters to you.
No image available
The named 24g inner bags provide a defined size for a single snack. If you use the separate salt sachet, check how the packet presents its salt figures before comparing it with ready-salted crisps.
No image available
These 25g inner bags give you a defined ready-salted option. Walkers UK lists 130 kcal and 0.34g salt per 25g for Ready Salted; check the current inner pack when using those figures to choose.
An individual bag is useful when you want its stated contents to define the amount you open. Walkers lists a typical 25g Lightly Salted pack, Tyrrells identifies its 40g Lightly Sea Salted pack as one serving, and REAL lists individual 35g Sea Salt & Black Pepper bags. With a sharing bag, check whether the label’s serving is smaller than the amount you intend to eat.
No. Walkers UK lists 0.17g salt per typical 25g Lightly Salted pack and describes it as having 45% less salt than the average value of regular potato crisps. That is a comparison, not a claim that the pack contains no salt.
No. Read the current packet’s ingredients and any precautionary statement, even for plain salted crisps. GOV.UK identifies packets of crisps as prepacked food and explains that regulated allergens present in the ingredients must be clearly labelled; the flavour name alone does not provide the full declaration.
