For repeated school lunches, compare drained weight per tin and pack count before choosing a larger multipack. A three-tin no-drain pack can simplify preparation but provides less cupboard stock than a four-tin pack. Choose spring water, brine or oil to suit the filling, and check the exact pack for fish allergens and storage directions.
Who these packs suit
Lunchbox batch planners
If you make sandwiches or wraps repeatedly, pack count alone will not tell you how much tuna is available for each filling. Compare the drained weight per tin as well as the number of tins; Tesco Groceries and Joybuy list multipacks in different sizes.
Fast-prep households
A no-drain format may suit lunches assembled in a hurry. John West lists a three-pack No Drain product, so check whether its smaller pack count works for your routine.
Label-first buyers
Check the exact pack when fish allergy, packing liquid, salt information or a sourcing claim affects your choice. Product variants can differ, and an older online listing should not replace the current label.
What matters when choosing
For school lunches and quick family meals, start with the usable amount of tuna, then decide which preparation format and packing liquid fit the meals you plan to make.

What to check |
Who this matters to |
| Usable quantity |
Check tin count and drained weight per tin; net weight also includes packing liquid. |
If I am making several lunches from the cupboard, I need to know how much tuna each tin yields and when I will need another pack. About 31% of consumers put usable quantity first. |
| Quick preparation |
Look for an explicitly stated no-drain format and check how many tins are in the pack. |
On a rushed school morning, avoiding a draining step matters more to me than keeping a larger stock of tins. Quick preparation is the primary need for about 31% of consumers. |
| Packing liquid and meal fit |
Choose spring water, brine or oil for the intended filling, then read the exact pack’s salt and fat figures. |
When I am mixing tuna into sandwiches or pasta, I want the packing liquid and labelled nutrition to suit that recipe. About 23% of consumers make meal fit their main concern. |
| Allergen and sourcing labels |
Read the current fish-allergen declaration and check any sourcing claim on the selected product. |
If a fish allergy or a stated fishing method governs what I can buy, I need to inspect the exact pack rather than rely on a brand-wide assumption. Label assurance comes first for about 15% of consumers. |
Mistakes to avoid
-
Counting all of a tin’s net weight as tuna
A 145g tin includes packing liquid. The Joybuy listing for Princes Tuna Chunks in Spring Water 12 x 145g states 102g drained tuna per tin.
Plan fillings using the drained weight shown for the pack you choose, particularly when comparing tins of different sizes.
-
Assuming every packing liquid gives the same nutrition
Spring-water, brine and oil variants can carry different labelled fat and salt figures. A liquid name on its own is not a substitute for the nutrition panel.
Choose a liquid that works in the recipe, then compare figures on the same per-100g basis and check whether they refer to drained tuna.
-
Using an old listing for an allergy decision
Fish is an allergen in tinned tuna, and ingredients or allergen information can change. Shellfish is a separate allergen category; do not assume it is present in plain tuna.
For anyone with a fish allergy, do not buy or serve tuna. Read the current physical pack’s ingredients and allergen statement before serving.
-
Opening a tin without a plan for the remainder
A multipack keeps unopened tins available, but it does not change the storage directions for tuna left over from an opened tin.
Follow the selected pack’s instructions. The reviewed Asda and M&S products direct buyers to transfer leftovers to a non-metal container, refrigerate them and use them within two days.
Brands to compare
John West
Compare its conventional multipacks with its distinct No Drain range if preparation time matters.
- John West describes its No Drain Tuna Chunks in Spring Water MSC product as a three-pack containing tuna, spring water and salt.
- The No Drain format and MSC claim apply to that product, not automatically to every John West multipack. Check the selected pack’s size and label.
Princes
Its tuna-chunk range includes brine, spring-water and sunflower-oil choices.
- Princes Food and Drinks lists its brine chunks in 145g tins and 3 x 80g, 4 x 145g and 6 x 145g formats.
- Check the liquid on the particular variant. Princes lists tuna, water and salt for its brine product, which is not the ingredient list for every variant.
Tesco
Its own-label three-tin format offers a smaller multipack to compare with larger packs.
- Tesco Groceries lists 3 x 80g own-label tuna chunks in brine and spring water.
- A 3 x 80g pack is a different stock-up quantity from a 4 x 145g pack; compare the drained amounts for your planned meals.
Sainsbury’s
Its own-label 4 x 145g multipacks include different packing liquids.
- Sainsbury’s lists 4 x 145g spring-water and brine tuna-chunk packs, alongside oil variants.
- J Sainsbury plc stated in 2023 that its own-label canned tuna was MSC-certified and pole-and-line-caught. Check the current selected pack rather than treating that historical statement as a permanent product guarantee.
Asda
Its own-label 4 x 145g brine multipack is a standard chunk-tuna format for comparison.
- Asda lists tuna, water and salt as ingredients for its 4 x 145g brine pack.
- Asda directs buyers to transfer unused contents to a non-metal container, refrigerate them and use them within two days. Follow the directions on the pack purchased.
M&S
Check its product-specific sourcing statements if fishing method matters to your purchase.
- M&S describes its reviewed 160g spring-water tuna as pole-and-line-caught under its Forever Fish policy; its listed ingredients are skipjack tuna and spring water.
- That description concerns the reviewed product. Check the selected multipack for its own sourcing statement, ingredients and pack size.

Common questions
Does tinned tuna contain a UK-declared allergen?
Yes. Fish is among the allergens covered by UK food-allergen guidance from the Food Standards Agency. Crustaceans and molluscs are separate categories, so do not assume plain tuna contains shellfish; check the current pack. Do not buy or serve tuna to someone with a fish allergy.
Should I plan portions using net weight or drained weight?
Use drained weight when planning how much tuna will go into a filling, where the selected pack states it. Net weight includes the packing liquid: Joybuy’s Princes 12 x 145g spring-water listing, for example, states 102g drained tuna per tin.
How should I store tuna left over from an opened tin?
Follow the directions on the pack you buy. The reviewed Asda and M&S products instruct buyers to transfer unused tuna to a non-metal container, refrigerate it and use it within two days.
