For a cinema snack chosen chiefly for protein, compare protein crisp-style snacks rather than assuming ordinary potato crisps serve the same purpose: Applied Nutrition lists 15g protein per 50g bag of Protein Chips, while Walkers lists 1.6g per 25g pack of Ready Salted crisps. Choose conventional potato crisps when their texture or a particular flavour matters more to you, and check pack size, salt and the exact flavour’s ingredients before buying.
The choice depends on whether protein, familiar potato-crisp texture or a particular ingredient requirement comes first.
Look at protein per pack in a crisp-style snack, rather than relying on the word “protein” in its name. For a “high protein” claim, the nutrition-claim condition published on legislation.gov.uk requires protein to provide at least 20% of the food’s energy.
If flavour and familiar potato-crisp texture are the main reasons for buying a film snack, a conventional crisp may suit you. For protein, compare the actual pack: Walkers lists 1.6g in a 25g Ready Salted pack, and Seabrook lists 0.7g in an 18g Crunchies Salt & Vinegar bag.
Check the exact product and flavour. Protein crisp-style snacks in this comparison use ingredients including soy, milk or pulses; KETTLE Chips labels its Sea Salt & Balsamic Vinegar potato crisps gluten-free and suitable for vegans and vegetarians. Those statements should not be assumed to cover other flavours.
Choose when: You want the snack itself to provide more protein than the conventional crisp packs compared here.
Bear in mind: These products are not necessarily sliced potato crisps; their ingredient bases and allergen statements vary.
Choose when: Familiar potato-crisp texture or a particular flavour matters more than protein per pack.
Bear in mind: The Walkers and Seabrook individual packs cited here provide much less protein than the dedicated protein crisp-style examples, according to their brands’ nutrition declarations.
Compare the portion you would actually take to the cinema, then check the ingredients and the venue’s rules.
| Priority | What to check | Your needs |
|---|---|---|
| Protein per snack | Compare protein and energy for the same whole pack or serving. Applied Nutrition declares 15g protein and 210 kcal per 50g bag; Myprotein declares 11g and 100 kcal per 25g pack. For a “high protein” claim, the condition published on legislation.gov.uk is that at least 20% of energy comes from protein. | I want to know how much protein the portion I will eat provides, without treating a larger bag and a smaller pack as equal servings. |
| Crisp type | Check whether the base is conventional potato or a crisp-style mixture. Walkers declares 1.6g protein per 25g Ready Salted pack; Tyrrells declares 3.9g per 30g serving of its lentil crisps. | Potato-crisp texture may matter more to me than protein, or I may want to consider a lentil option without assuming it matches a dedicated protein crisp. |
| Pack size | Check whether the package is a single serving or a larger box or bag, and compare salt and energy on the portion you intend to eat. Do not treat a per-100g figure as a per-pack figure. | I would rather carry one portion into a film than work out how much of a larger package to take. |
| Venue rules | Check the individual cinema’s current outside-food policy before bringing a pre-bought snack. YouGov Profiles data collected from August 2024 to August 2025 found that 30% of surveyed adults aged 18+ in Great Britain selected “Nothing” when asked what they spend on refreshments or snacks at standard 2D cinema screenings; that does not establish whether outside food is permitted. | I want to decide whether to buy a snack before the film or at the venue. I’ll check the cinema’s policy rather than assume I can bring food in. |
| Salt and ingredients | Read the exact flavour’s salt value, ingredients and allergen statement. SlimFast lists soy protein in its Barbeque Protein Crisps; Myprotein lists soy and milk-containing ingredients for the cited Protein Crisps flavours. | Protein is not my only consideration: I also need the particular flavour’s ingredients and salt declaration to fit what I’m looking for. |
Protein grams alone do not establish eligibility for that claim. Under the nutrition-claim condition published on legislation.gov.uk, protein must provide at least 20% of the food’s energy.
Use protein and energy figures for the same serving basis. To check the energy share, multiply protein grams by 4 kcal, divide by total kcal and compare the result with 20%.
Applied Nutrition declares 15g protein and 210 kcal in a 50g Protein Chips bag, while Myprotein declares 11g and 100 kcal in a 25g Protein Crisps pack. Those are different quantities of snack, not interchangeable portions.
Compare protein, energy and salt for the complete portion you expect to eat.
The cited products differ in ingredients and salt declarations. SlimFast lists 0.47g salt per serving of Barbeque Protein Crisps; Myprotein lists 0.75g per 25g pack for the cited Protein Crisps flavour.
Read the current label for the exact flavour, particularly if you avoid soy, milk, gluten-containing cereals or pulses.
A product’s nutrient-profile classification cannot be established from the word “crisps” alone. Department of Health & Social Care technical guidance requires the applicable nutrient data to assess a particular food; the school-food guidance cited here concerns England, not a single rule for every UK school setting.
If buying for a school setting, check the product’s current nutrition information and the rules applicable to that setting and nation. Do not use a cinema-snack category label as a school-food assessment.
These named products show different crisp formats and label details; a statement about one flavour does not apply to an entire brand range.
Walkers Ready Salted is a conventional potato-crisp reference for comparing individual packs.
The cited Sea Salt & Balsamic Vinegar product is a hand-cooked potato crisp.
Tyrrells’ cited lentil crisps offer a pulse-based alternative to conventional potato crisps.
Seabrook Crunchies Salt & Vinegar is a formed potato snack made with dried potato and potato starch.
Pipers describes its potato crisps as boldly flavoured and made with selected flavourings.
This lentil-cake option is a crisp-style snack to consider if you are choosing something portable for a film. Its 100g box is a different format from the individual protein-crisp bags discussed above, so compare the portion you plan to take.

The 100g lentil-cake box is an alternative to taking an individual bag of crisps to the cinema. Check the pack’s serving information and ingredients when deciding how much to take.
Do not assume they are from the category name. Walkers declares 1.6g protein in a 25g Ready Salted pack, KETTLE Chips declares 4.3g per 100g of Sea Salt & Balsamic Vinegar crisps, and Seabrook declares 0.7g in an 18g Crunchies Salt & Vinegar bag. Compare protein and energy on the same portion basis if a “high protein” claim matters to you.
The nutrition-claim condition published on legislation.gov.uk requires at least 20% of the food’s energy value to come from protein. Using nutrition figures for the same serving, multiply protein grams by 4 kcal and divide by total kcal to check that proportion; the presence of protein alone is not enough.
No: compare the pack sizes and energy declarations too. Applied Nutrition lists 15g protein and 210 kcal for a 50g Protein Chips bag, while Myprotein lists 11g and 100 kcal for a 25g Protein Crisps pack. Check salt and ingredients for the particular flavour you would buy.
Suitability depends on the exact product and flavour. Applied Nutrition describes its Protein Chips as gluten-free and soy-free and lists pulse ingredients including pea protein, lentil flour and fava beans. Myprotein lists soy and milk-containing ingredients for the cited Protein Crisps flavours and warns of possible traces. Read the current pack’s ingredient and allergen statements before choosing.
A category name alone does not establish an individual crisp’s nutrient-profile classification or the rules for a particular school setting. Department of Health & Social Care technical guidance uses product nutrition data for classification, while the cited Department for Education school-food guidance concerns England. For a school purchase, check the specific product and the requirements applicable to that setting and UK nation.
