Meal Box, Bento & Delivery Sealing
Delivery and bento demand leak-proof seals, easy-peel lids and enough throughput. Meal boxes, bowls and soup containers differ from drink cups in size and sealing behaviour. Kaiwill matches the right sealer and film to your container type and volume.
Questions you may have
- Will soups and sauces leak in transit during delivery?
- Do different box and bowl sizes need die changes — and how much hassle is that?
- Can customers peel the lid easily without it splashing?
- Can sealing keep up with the lunch bento rush?
Recommended equipment tiers
Tiers below are a conservative guide by scale; the exact entry/main/high-volume placement of each model is confirmed by Kaiwill.
Main line
For caterers with steady delivery volume and multiple box sizes. Higher-automation desktop sealers supporting multiple container sizes.
High volume
For central kitchens, group meals and high-volume bento lines. Consider industrial box filling-and-sealing equipment for continuous production.
High-volume placement to be confirmed by Kaiwill per actual line.
Suitable containers & films
- Containers: plastic meal boxes, bowls, soup cups — sizes and depths vary widely
- Films: easy-peel, leak-resistant films recommended for delivery; confirm compatibility by container material
- Dies: different box sizes may need matching dies — confirm the change-over process first
See the Sealing Film & Consumables page for film-compatibility details.

Buying notes

- For delivery soups, test the leak-proof result — send samples for an actual seal test.
- If you run multiple container sizes, check how easy and how fast the die change-over is.
FAQ
Can soup containers be sealed leak-proof for delivery?
Leak-proofing depends on the container, film and sealing settings together. Send your containers for an actual seal test — go by the measured result.
Do different box sizes need a die change?
