For a weekly shop, choose a multipack if you need a set number of ready-to-pack snacks, or a grab bag if you want one larger individual portion. A sharing bag works when you intend to divide it. Check the weight and nutrition information for the amount you expect to eat: packs labelled as one serving can contain different amounts.
Who each format suits
Lunchbox and desk-snack planners
A multipack gives you separate bags to allocate across the week. The Walkers Ready Salted 6 × 25g and Tyrrells Lightly Salted 5 × 25g examples listed by Tesco have 25g inner packs, so there is no need to divide an opened sharing bag for each snack.
Shoppers wanting one larger snack
A grab bag can suit a single occasion when a 35g or 45g bag is the amount you intend to eat. Tesco lists both its REAL Sea Salt 35g bag and Walkers Ready Salted 45g bag as one serving; that wording does not make them the same size as a 25g multipack packet.
Shoppers checking ingredients and labels
Compare the exact flavour and pack for ingredients, allergen statements and nutrition. A plain-sounding flavour or a familiar brand name cannot stand in for the current packet label.
What to check before buying
Start with how many separate snacks you need, then compare the labels for the packs you would actually eat.
| Priority |
What to check |
Your needs |
| Portions for the week |
Check the number and weight of inner packs, or the servings stated on a larger bag. Tyrrells lists five 30g servings for its Lightly Sea Salted 150g bag. |
I need separate bags for lunches, or I can divide a sharing bag into the portions I plan to use. |
| Amount in one bag |
Compare bag weight and per-pack calories and salt. Tesco lists 234 kcal and 0.54g salt for a Walkers Ready Salted 45g grab bag, versus 130 kcal and 0.30g salt for its 25g multipack packet. |
A grab bag suits me when I want that larger individual portion, rather than simply substituting it for a 25g packet. |
| Ingredients and allergens |
Read the ingredients and precautionary allergen statement for the exact flavour. Tyrrells says its Lightly Sea Salted product may contain milk; Walkers lists allergens handled in the factory for Ready Salted. |
When buying for someone with an allergy or dietary requirement, I need to check the current packet, even for a plain flavour. |
| Flavour and style |
Check the flavour and cut named on the pack. Seabrook lists a crinkle-cut range; plain and lightly salted recipes should still be compared product by product. |
Perhaps I want a particular flavour or a ridged crisp, alongside a pack size that fits the week. |
Common buying mistakes
-
Assuming “one serving” always means the same amount
Tesco labels both the Walkers Ready Salted 25g multipack packet and 45g grab bag as one serving, although their listed per-pack calories and salt differ.
Compare the weight and nutrition information for the whole bag you expect to eat before swapping one format for the other.
-
Using a plain flavour as an allergy shortcut
A short ingredient list does not rule out a precautionary allergen statement. Tyrrells says its Lightly Sea Salted product may contain milk.
Read the current label for the exact product and flavour when buying for someone with an allergy or intolerance.
-
Choosing a sharing bag for ready-packed lunches
A sharing bag does not provide separate snack packets. Tyrrells lists five 30g servings for its Lightly Sea Salted 150g bag, but those portions must be divided.
Choose a multipack for separate bags, or portion a sharing bag yourself if that format fits your plans.
Brand and range references
These examples show formats and styles to compare; pack sizes and label details belong to the specific products named.
Walkers
Walkers Ready Salted provides an example of both a multipack portion and a larger individual grab bag.
- Tesco lists a 6 × 25g multipack with each inner bag marked as one serving, and a 45g grab bag also marked as one serving.
- The sizes have different per-pack nutrition figures. Check the current flavour label and allergen information rather than applying Ready Salted details to the whole range.
Tyrrells
Tyrrells Lightly Sea Salted illustrates the choice between individual packs and a bag to divide.
- Tyrrells lists a 150g bag as five 30g servings; Tesco has also listed Lightly Salted in a 5 × 25g format.
- The Lightly Sea Salted product says it may contain milk. Confirm the exact pack and its availability when shopping.
KETTLE Chips
KETTLE Chips lists a Lightly Salted potato-crisp recipe for shoppers comparing plainly seasoned options.
- The brand’s Lightly Salted page lists potatoes, vegetable oils and sea salt, and states vegan, vegetarian and gluten-free suitability for that product.
- Check the size and current label of the retail pack you choose before treating its nutrition information as a grab-bag portion.
Seabrook
Seabrook’s original range is a reference for shoppers seeking crinkle-cut crisps.
- The brand lists flavours including Sea Salted, Cheese & Onion and Sea Salt & Vinegar.
- Choose by the specific flavour, pack format and label rather than assuming the range has one ingredient profile.
Pipers
Pipers describes its range in terms of pronounced flavours and sourced seasonings.
- Its range may be worth checking when flavour choice is a priority for the shop.
- Brand positioning does not establish the pack size, ingredients or dietary suitability of a particular flavour; check its label.
REAL Hand Cooked Crisps
REAL Sea Salt offers a 35g individual-bag example alongside a 150g format.
- REAL lists both sizes, while Tesco identifies the 35g bag as one serving.
- Use the nutrition and allergen information on the current pack when comparing it with another size or flavour.

Frequently asked questions
Is a 45g grab bag the same portion as a 25g multipack packet?
No. Tesco labels both Walkers Ready Salted formats as one serving, but lists 234 kcal and 0.54g salt for the 45g grab bag, compared with 130 kcal and 0.30g salt for the 25g inner packet. Compare the whole bag you intend to eat.
How can I compare crisps sold in different bag sizes?
Check per-pack figures for the amount you plan to eat, then use per-100g figures to compare products on the same weight basis. GOV.UK also explains that front-of-pack traffic-light labels help compare fat, saturates, sugars and salt at a glance.
Are plain sea-salt crisps automatically suitable for someone with a milk allergy?
No. Tyrrells says its Lightly Sea Salted product may contain milk despite its short core ingredient list. Read the current packet for the exact product and flavour rather than relying on the flavour name.
Can a sharing bag work for weekly snacks?
Yes, if you plan to divide it yourself. Tyrrells lists five 30g servings for its Lightly Sea Salted 150g bag, but the bag does not provide five separate packets.
