Travellers planning one snack stop
An individual packet makes the amount you intend to eat easier to identify than a sharing bag. Compare calories for that packet, not just for a serving printed on a larger pack.
Who is choosing?
Travellers comparing salt as well as calories
A smaller packet can have fewer calories without having less salt per 100g. Check both figures if they matter to your choice.
Groups with different dietary requirements
Check the ingredients and allergen statements for each flavour before setting off. A vegetarian label does not, by itself, tell you whether a product contains milk.
What should you compare?
Start with the packet you would actually eat, then use the per-100g figures to compare products sold in different sizes.
| Priority | What to check | Your needs |
|---|---|---|
| Calories per snack | Read the kcal per pack or serving and its weight. Compare kcal per 100g when assessing recipes across different pack sizes. | I want to know the calories in the whole packet I plan to eat at one stop, rather than mistake a smaller bag for a lower-calorie recipe. |
| Salt | Compare salt per 100g across products and salt per pack for the amount eaten. NHS food-label guidance classifies more than 1.5g salt per 100g as high. | The packet’s calorie figure matters to me, but I also want to compare its salt content. |
| Pack format | Check the declared pack weight and whether a larger bag contains multiple servings. If dividing a sharing bag, decide on the portion before travelling. | A sealed individual packet would make it simpler to plan one snack for the journey. |
| Ingredients and allergens | Read the current ingredients, allergen statement and any may-contain warning for the exact flavour. Do not use a vegetarian label as a substitute. | I’m buying for passengers with different dietary needs, so each flavour needs its own label check. |
Common buying mistakes
-
Assuming the lowest packet calories mean the lowest-calorie recipe
Seabrook lists 82 kcal for an 18g Sea Salted Crunchies bag, while Walkers lists 96 kcal for a 22g Oven Baked Sea Salt pack. Those packet figures represent different amounts of food.
Choose the pack size you intend to eat, then compare both kcal per pack and kcal per 100g.
-
Assuming baked or lentil crisps are low in salt
Seabrook lists 1.69g salt per 100g for Sea Salted Crunchies, and Tyrrells lists 2.1g per 100g for its Sweet Chilli & Red Pepper Lentil Crisps. Both exceed the NHS high-salt labelling threshold of more than 1.5g per 100g.
Check salt per 100g for comparison and salt per pack or serving for the amount you expect to eat.
-
Treating a sharing bag as one planned portion
Tyrrells lists 208 kcal for its 40g Lightly Sea Salted pack and also offers larger 150g and 600g formats. A per-serving label on a larger bag does not describe the whole bag.
Pick an individual pack or portion a larger bag before the journey.
Brand references
These examples show why the exact range, flavour and pack size matter more than the brand name alone.
Walkers
Its cited Oven Baked Sea Salt and standard Cheese & Onion packs provide two different portion and recipe references.
- Walkers lists 96 kcal and 0.19g salt for a 22g Oven Baked Sea Salt pack.
- Its cited standard Cheese & Onion pack is 25g and lists 128 kcal; check the exact flavour and allergen statement rather than applying either figure to the whole range.
Seabrook
Its cited Crunchies snack bag is smaller than its cited standard Sea Salted crisp bag.
- Seabrook lists 82 kcal for an 18g Sea Salted Crunchies bag.
- That product lists 1.69g salt per 100g; Seabrook’s standard Sea Salted crisps have a different 31.8g bag and list 164 kcal per bag.
Tyrrells
Its cited products include potato crisps and a lentil-crisp alternative in different portion sizes.
- Tyrrells lists 140 kcal for a 30g serving of Sweet Chilli & Red Pepper Lentil Crisps.
- The same lentil flavour lists 2.1g salt per 100g, while its Lightly Sea Salted potato crisps list 208 kcal for a 40g pack.
Kettle Chips
Its cited Sweet Chilli & Sour Cream crisps are labelled gluten-free and suitable for vegetarians.
- The product page gives nutrition figures per 100g, allowing comparison with other flavours on the same weight basis.
- It lists 505 kcal per 100g; check the weight of the pack you plan to take to work out the packet amount.
McCoy's
Its range includes ridged crisps and sharing formats.
- McCoy's publishes per-100g nutrition for its cited Salted flavour.
- That flavour lists 533 kcal and 32g fat per 100g; check the chosen packet’s weight and serving information before comparing packet totals.
REAL Hand Cooked Crisps
REAL describes its crisp range as vegetarian and gluten-free, with some recipes suitable for vegans.
- Its range information can help narrow a search by dietary label.
- Check the current flavour’s ingredients, allergen statement and pack nutrition before deciding whether it suits your travellers and planned portion.

Questions about road-trip crisps
Does the packet with the fewest calories have the lower-calorie recipe?
Not necessarily. Seabrook lists 82 kcal for an 18g Sea Salted Crunchies bag, while Walkers lists 96 kcal for a 22g Oven Baked Sea Salt pack. Compare the weight and kcal per 100g as well as the calories in the packet you intend to eat.
Why check salt when choosing by calories?
Calories and salt describe different parts of the nutrition label. NHS guidance classifies more than 1.5g salt per 100g as high; Seabrook lists 1.69g per 100g for Sea Salted Crunchies, and Tyrrells lists 2.1g per 100g for Sweet Chilli & Red Pepper Lentil Crisps. Check salt per pack too if you plan to eat the whole packet.
Do vegetarian crisps necessarily suit dairy-free or vegan passengers?
No. Walkers’ cited Cheese & Onion crisps contain milk-derived ingredients, while Seabrook labels its Sea Salted Crunchies suitable for vegetarians and vegans. Read the current ingredients and allergen statement for the exact flavour before travelling.
