Kraft Bioboxes: No.1 to No.12 Sizes Explained
The DiscountTillRolls.ie TeamBiobox numbers don't run in size order, which trips a lot of people up. From smallest to largest, our range goes No.1 (26oz), No.12 (34oz), No.8 (45oz), No.2 (49oz), No.3 (66oz) and No.4 (96oz). As a rough guide, the No.1 suits sides and snacks, the No.12 and No.8 suit a single main meal, and the No.2, No.3 and No.4 suit large meals, sharing and catering.
Bioboxes are the fold top kraft boxes you see at street food stalls and noodle bars. They close without a separate lid and hold hot food well.

Which box for which dish?
- Noodles and stir fry: No.12 or No.8 for one person.
- Curry and rice: No.8 or No.2, depending on your portion.
- Loaded fries and wings: No.8 for one, No.3 for sharing.
- Catering and family boxes: No.4.
The easiest test is to plate your normal portion and see which box it fills to just below the fold. Ordering a sample case of two sizes first saves guesswork.
Why use bioboxes?
- No separate lid: the top folds shut, so there is one item to stock.
- Built for hot food: the kraft board has a grease resistant lining.
- Stacks flat: they arrive flat and take up little storage space.

Tips
- Don't overfill. The flaps need to close without pressing on the food.
- Pair with a carrier bag. Flat bottomed SOS or handled bags keep boxes level.
