Families planning several tuna meals
If tuna regularly goes into pasta, sandwiches, jacket potatoes or salads, several sealed tins let you open only what the next meal needs. Check the weight of the tuna you can use, not just the pack count.
Who is shopping for these packs?
Households comparing food labels
If salt or ingredients influence your choice, compare the exact packs. ASDA Groceries and Sainsbury's list different salt figures for their 4 x 145g spring-water tuna chunks.
Households wanting quick portions
A smaller no-drain tin can suit a lunch or sandwich filling when draining is inconvenient. John West's listed no-drain three-pack contains 100g tins, rather than the 145g tins in several conventional four-packs.
What matters when choosing?
For a large family shop, decide whether usable quantity, label details, quick portions or sourcing information takes priority; then compare packs on that basis.
| Concern | What to check | Who this matters to |
|---|---|---|
| Usable quantity | Compare the number of tins and their net and drained weights where shown. | If tuna is on the menu several times, I want enough separately sealed tins without opening one large container. About 40% of consumers put usable quantity first. |
| Salt and ingredients | Read the ingredients and compare salt per 100g on the same drained or undrained basis. | When I choose spring-water tuna, I still need to check whether its salt figure suits what I am looking for. Roughly 30% of consumers make label comparison their primary concern. |
| Portion and preparation | Match tin size and no-drain or conventional format to the meals you plan. | For a quick lunch, I would rather open a smaller portion without draining it, even if that leaves fewer tins for later meals. About 20% of consumers prioritise convenient portions. |
| Sourcing information | Look for fishing-method or certification statements on the exact product. | If the stated catch method matters to me, I want to check the particular tin rather than rely on a brand-wide impression. Approximately 10% of consumers put sourcing information first. |
What should you avoid overlooking?

Assuming all spring-water packs have similar salt levels
ASDA Groceries lists 0.90g salt per 100g drained for its 4 x 145g spring-water chunks; Sainsbury's lists 0.12g per 100g drained for its equivalent pack format. The packing liquid alone does not settle that comparison.
Read the current nutrition panel on each pack and compare figures stated on the same basis before stocking up.

Expecting a no-drain three-pack to stock the cupboard like a larger multipack
John West's no-drain format is listed as 3 x 100g. It offers smaller portions with less draining, whereas the conventional family packs discussed here contain four 145g tins.
Choose the smaller format for meals where preparation matters most; check the total quantity if the aim is several family meals.
-
Treating every opened tin the same way
Opened-product instructions differ. ASDA Groceries and Princes specify use within two days after refrigeration for their cited packs; Sainsbury's specifies one day for its cited four-pack.
Follow the storage instructions on the tin you buy, including any direction to transfer leftovers to another container, and plan when you will use them.
Opening more tuna than a meal needs can leave leftovers that must be used within that product's stated storage window.
Brands to consider
These examples show different pack formats and product-specific label details. A claim or specification for one tin should not be assumed to apply across a brand's range.
John West
Tesco Groceries lists John West No Drain tuna chunks in 3 x 100g packs, including spring-water and brine versions.
- The smaller no-drain tins suit meals where draining a conventional tin is inconvenient.

ASDA Groceries lists Princes spring-water tuna chunks in a 4 x 145g pack.
- Four sealed tins allow the household to open them across separate meals.
- The cited spring-water pack lists 0.85g salt per 100g drained; check the exact pack when comparing salt.

- The cited ingredients are tuna and spring water, and the listing carries an MSC statement for this product.
- Its listed 0.90g salt per 100g drained differs from Sainsbury's cited spring-water four-pack, so compare the labels rather than assuming the formats match.

Common questions
How do I compare tuna multipacks of different sizes?
Check both the number of tins and the drained weight where it is stated. A four-pack of 125g tins and a four-pack of 145g tins have the same tin count but different stated net quantities; the drained-weight labels help you compare the tuna available for meals.
How long can I keep tuna after opening a tin?
Follow the instructions on the exact tin. The cited ASDA Groceries and Princes packs specify refrigeration and use within two days after opening, while Sainsbury's specifies one day for its cited four-pack.
Can I assume two spring-water multipacks have the same salt figure?
No. ASDA Groceries lists 0.90g salt per 100g drained for its cited four-pack, while Sainsbury's lists 0.12g per 100g drained for its cited four-pack. Compare the current labels using the same measurement basis.
What should I check if someone in the household has a fish allergy?
Tuna is fish, so check the ingredients on the exact product. The Food Standards Agency says allergens present in UK prepacked food must be emphasised in its ingredients list.
Does tinned tuna count as oily fish?
No. The NHS states that fresh and canned tuna do not count as oily fish; buying a larger tuna multipack does not change that classification.
