TV snackers planning a portion
If a sharing bag tends to stay open throughout a film, an individual bag makes its weight clear from the outset. Sainsbury’s lists the Propercorn Lightly Sea Salted multipack at 10g, 44 kcal and 1.7g fat per bag.
Who these choices suit
Shoppers comparing fat content
Compare the per-100g figures rather than flavour names or calories from differently sized servings. The checked Sainsbury’s and Tesco listings give 17.4g fat per 100g for Propercorn Lightly Sea Salted, 26.8g for Sainsbury’s Simply Salty and 31.2g for Tesco Salted.
People weighing salt against sugars
A sweet flavour changes the comparison. Tesco lists 20.7g sugars per 100g for its Sweet Popcorn, so check sugars as well as fat; for savoury choices, compare salt on the same per-100g basis.
What to check before choosing
Start with fat per 100g to compare products, then read the serving information to plan the amount for one viewing session.
| Priority | What to check | Your needs |
|---|---|---|
| Fat | Compare fat per 100g across products, then fat per labelled serving. Check the ingredient list if you also want to know whether oil is included. | I want to compare popcorn on the same quantity, rather than pick by a name such as “lightly salted”. |
| Portion size | Read the individual bag weight or the stated serving size and number of servings in a sharing bag. Sainsbury’s lists three 20g servings for the 70g Propercorn bag. | For a long film, I would rather decide on a portion before opening a sharing bag. |
| Salt and sugars | Compare salt in savoury options and sugars in sweet options, using both per-100g and serving figures. Read any traffic-light label alongside the full nutrition panel. | Lower fat is my starting point, but I also want to see what changes when I choose a sweet or salted flavour. |
| Dietary and safety labels | Check declarations and allergen or precautionary wording on the exact pack. Read its kernel warning and age guidance when buying for young children. | Our household needs the current pack’s dietary and safety information, not an assumption based on another flavour. |
Common buying mistakes
-
Assuming all popcorn has similar fat content
The checked Sainsbury’s and Tesco ready-to-eat products range from 17.4g to 31.2g fat per 100g. A flavour description does not tell you where a pack falls within that range.
Compare the fat figures per 100g first. Then check the amount you intend to serve rather than treating the product comparison as a portion decision.
-
Comparing calories from unequal servings
Sainsbury’s lists 44 kcal for a 10g Propercorn bag and 88 kcal for a 20g serving of the 70g version. Those figures describe different amounts of popcorn.
Use per-100g figures when choosing between products, and the labelled serving and servings per bag when planning your bowl.
-
Checking fat but overlooking salt or sugars
Tesco lists 23.4g fat and 20.7g sugars per 100g for its Sweet Popcorn. Its Salted Popcorn lists 31.2g fat and 1.26g salt per 100g. The nutrient you want to compare can change with the flavour.
Read sugars for sweet popcorn and salt for savoury popcorn, alongside fat in either case.
-
Opening a sharing bag without choosing a portion
Sainsbury’s lists approximately three 20g servings in the 70g Propercorn bag, while its 10g multipack separates the popcorn into individual bags.
If you choose a sharing bag, put your intended serving in a bowl before the film and close the remainder.
Brand and retailer references
These references describe particular products in the cited retailer listings, not every popcorn variety made by each brand.
Propercorn
Sainsbury’s lists Lightly Sea Salted ready-to-eat popcorn in a 6x10g multipack and a 70g bag.
- Both checked formats list 17.4g fat per 100g; the multipack lists 1.7g fat per 10g bag.
- The 70g listing gives 1.1g salt per 100g. Check the current pack rather than interpreting “lightly sea salted” as a salt comparison.
Tesco
The checked own-label range includes separate Salted and Sweet ready-to-eat products.
- Tesco lists 23.4g fat and 0.03g salt per 100g for its Sweet Popcorn.
- The Sweet Popcorn also lists 20.7g sugars per 100g; Tesco Salted lists 31.2g fat and 1.26g salt per 100g.
Sainsbury’s
Its checked Simply Salty Butterfly Popcorn is a 90g ready-to-eat bag with an 18g stated serving.
- The listing provides per-serving and per-100g nutrition figures, including 4.8g fat per 18g serving.
- It lists 26.8g fat and 1.38g salt per 100g; compare those figures with other salted products rather than relying on the plain flavour name.
Metcalfe’s
Tesco lists Metcalfe’s Skinny Popcorn Sweet ’N Salt in an 80g bag.
- The listing states 23.8g fat per 100g, allowing a like-for-like fat comparison with the other checked products.
- It also states 18.1g sugars and 1.3g salt per 100g, and warns that the product is not suitable for children under 4 years because of a choking hazard.
Tyrrells
Tesco lists Tyrrells Popcorn Lightly Sea Salted in a 70g bag.
- Use the nutrition panel on the exact pack to compare fat and salt; “lightly sea salted” is not itself a per-100g figure.
Joybuy popcorn options
These options include individual ready-to-eat bags, sharing bags and microwave popcorn for a TV night. Check the format before comparing portions: a microwave pack is not ready to eat straight from the bag.

Propercorn Lightly Sea Salted Popcorn 6x10g
Individual 10g bags let you choose a portion before watching. Sainsbury’s lists 17.4g fat per 100g and 1.7g fat and 44 kcal per 10g bag for this product. Check the current pack’s precautionary allergen wording if milk is relevant to your household.
No image available
Propercorn Lightly Sea Salted Popcorn 70g
The 70g ready-to-eat bag suits sharing or dividing into bowls before a film. Sainsbury’s lists 17.4g fat per 100g and 3.5g fat per 20g serving, with approximately three servings in the bag. Check the current pack’s precautionary allergen wording where relevant.
No image available
Propercorn Sweet & Salty 6x14g
Six individual 14g bags make the pack size clear before serving. Because this is a sweet-and-salty variety, compare its fat, sugars and salt on the current nutrition label rather than using figures from Propercorn’s Lightly Sea Salted product.
No image available
Butterkist Salted Microwave Popcorn 3x60g
This is a microwave option in three 60g packs, rather than a ready-to-eat bag. Check the pack’s preparation instructions, nutrition basis and stated serving size before comparing it with ready-to-eat popcorn or deciding how much to put in a bowl.
No image available
Joe & Seph’s Cinema Salted Popcorn Sharing Bag 60g
This 60g ready-to-eat sharing bag can be divided before the film if you want a defined portion. Compare the current pack’s per-100g fat and salt figures with other salted options, and read its precautionary allergen wording where relevant.
Popcorn questions
Does “lightly salted” mean popcorn has less fat?
No: a flavour name does not establish a fat comparison. Read the nutrition panel per 100g and per serving. Sainsbury’s lists Propercorn Lightly Sea Salted at 17.4g fat per 100g, while Tesco lists its Salted Popcorn at 31.2g per 100g.
Should I choose small bags or a sharing bag for a TV night?
Choose individual bags if you want the portion set before watching; Sainsbury’s lists 44 kcal and 1.7g fat in each 10g Propercorn Lightly Sea Salted bag. A sharing bag can work when you divide it first: the checked 70g version lists approximately three 20g servings.
Is sweet popcorn a lower-salt alternative?
It can be for the particular products compared, but check sugars as a separate measure. Tesco lists less than 0.01g salt and 5.6g sugars per 27g serving of its Sweet Popcorn; those figures do not describe other sweet varieties.
What should I check when buying popcorn for young children?
Read the safety wording on the exact pack. Tesco’s listing for Metcalfe’s Skinny Popcorn Sweet ’N Salt warns of a choking hazard and states that it is not suitable for children under 4 years; do not assume every product carries identical guidance.
How should I store an opened bag?
Follow the instructions on its pack. For the checked Tesco Salted Popcorn, Tesco advises a cool, dry place and an airtight container once opened.
