Who is choosing?

The right crisp packet depends on whether you are packing one lunch, serving a group or comparing the amount in each bag.

Individual lunch packers

A sealed 25g, 31.8g, 35g or 40g packet gives one person a defined portion without opening a sharing bag. Choose the bag weight to fit the rest of the picnic lunch and the space available.

Hosts serving different dietary needs

Check each selected flavour’s ingredients, allergen advice and any vegetarian, vegan or gluten-free labelling. Packets from the same brand need not carry the same information.

Shoppers comparing portions

Look at energy and salt for the complete bag you plan to pack, not only the per-100g figures. That matters when the packets under consideration have different weights.

What should you check?

Start with the number and weight of individually sealed packets. Then compare the exact flavours and labels before deciding which multipack fits your picnic.

PriorityWhat to checkYour needs
Bag size Check the weight of each sealed packet, not just the multipack weight. Named examples include 25g Walkers and Seabrook bags, a 31.8g Seabrook bag, 35g REAL bags and 40g Tyrrells bags. I want one packet per person without dividing up a sharing bag; the portion needs to fit alongside the rest of lunch.
Ingredients Read the ingredient list, emphasised allergens and any 'may contain' statement on the exact flavour. Check dietary labels on that product rather than applying one flavour’s label to the whole brand. Someone in our group has dietary requirements, so I need to identify a suitable individual packet before packing it.
Per-bag nutrition Compare per-100g values for the product, then check energy and salt for the whole bag. Walkers UK lists 127 kcal and 0.16g salt for its 25g Prawn Cocktail pack; Tyrrells lists 0.26g salt for its 40g Lightly Sea Salted pack. When the packet sizes differ, I want the figures for the portion that will actually go into the lunch.
Flavour and quantity Check how many separate bags the multipack contains and which flavours are included. For a mixed pack, inspect each flavour’s label separately. I may want a choice of flavours for a group, but I still need a suitable packet for each person.

Picnic-packing mistakes to avoid

  • Buying a sharing bag for separate lunches

    One large open packet does not give each person their own sealed portion and may need dividing at the picnic.

    For individually packed lunches, check both the number of packets and the weight of each one. Choose a sharing bag when you intend to serve crisps together.

  • Assuming every flavour has the same allergens

    Ingredient and precautionary allergen statements can differ by flavour. Tyrrells Lightly Sea Salted, for example, carries a 'May contain Milk' statement despite its short ingredient list.

    Read the label on each flavour you purchase, particularly when packing for someone with an allergy.

  • Comparing nutrition only per 100g

    A 25g packet and a 40g packet are different complete portions, even when per-100g figures provide a useful product comparison.

    Check energy and salt per whole packet as well as per 100g, using the weight shown on the bag you are buying.

  • Leaving the multipack choice until picnic day

    A particular flavour, pack count or delivery option may not be available when you need it.

    Check current stock and delivery eligibility before planning lunches around one multipack, and keep another suitable packet size or flavour in mind.

Brand and pack-format references

These examples show why it is worth comparing individual packet weights and flavour labels; a brand name alone does not settle either question.

Walkers

Its Prawn Cocktail crisps provide an example of a 25g individual packet for a packed lunch.

  • Walkers UK lists 127 kcal and 0.16g salt per 25g Prawn Cocktail pack.
  • The same flavour carries a 'May contain' statement that includes milk; check the specific flavour and packet.

Tyrrells

Lightly Sea Salted comes in a 40g pack identified by Tyrrells as one serving, as well as larger formats.

  • The 40g individual pack offers a different portion size from a 25g lunch packet.
  • Its allergen advice says 'May contain Milk'; a short ingredient list does not replace that check.

KETTLE Chips

KETTLE lists cases of 18 individually sized 40g bags, including Lightly Salted and Sea Salt & Balsamic Vinegar.

  • The case format provides separate 40g packets for group packing.
  • Check current availability and the label of the chosen flavour before relying on a case for a particular picnic.

Seabrook

Its Canadian Ham example is a 25g bag, while Sea Salted is listed as a 31.8g bag.

  • The two named flavours offer different individual packet weights.
  • Their per-bag nutrition and dietary labelling should be checked by flavour, not assumed to match.

Pipers

Anglesey Sea Salt is listed in a 40g individual format and a larger 150g format.

  • The named product is labelled gluten-free and suitable for vegetarians.
  • Choose the 40g format if you need a separate bag per person, and check the purchased packet’s dietary information.

REAL Hand Cooked Crisps

REAL lists a mixed box of 24 individual 35g packets with a selection of flavours.

  • Separate 35g bags allow a group to choose among the flavours in the box.
  • Check each flavour’s ingredients: REAL Strong Cheddar & Onion lists milk ingredients.

Joybuy picnic-lunch options

Common questions

What size crisp bag should I pack for one picnic lunch?

Choose the individual packet weight in relation to the rest of the lunch rather than assuming one size suits everyone. The named examples run from 25g Walkers and Seabrook bags through 31.8g Seabrook and 35g REAL bags to a 40g Tyrrells pack; check nutrition for the complete packet you choose.

Is a sea-salt flavour suitable for every guest?

No. Check the exact product’s dietary labels, ingredients and precautionary allergen advice. Pipers Anglesey Sea Salt is labelled gluten-free and suitable for vegetarians, while Tyrrells Lightly Sea Salted carries a 'May contain Milk' statement.

What allergen information should I look for on prepacked crisps?

Look for the ingredient list and any emphasised allergens, then read any precautionary statement on the packet. Food Standards Agency guidance says allergens present in prepacked food must be emphasised each time they appear in the ingredients list; check the particular flavour you are serving.

How do I compare salt in bags of different sizes?

Check salt per whole bag to compare the portions you intend to pack, and use per-100g figures when comparing the products themselves. For example, Walkers UK lists 0.16g salt per 25g Prawn Cocktail pack, while Tyrrells lists 0.26g per 40g Lightly Sea Salted pack. The NHS advises adults to have no more than 6g of salt a day.

How should I pack sealed crisp packets for a picnic?

Keep the packets sealed until they are served, protect them from being crushed and follow the storage instructions on the purchased pack. If each person needs a separate portion, count the individual packets before leaving rather than relying on the multipack’s total weight.
