Rectangular lunch boxes (500-1000 ml)
Rice-grain and standard rectangular boxes stack flat in delivery bags. 500 ml suits bento and rice sets, 650-750 ml is the global default for one-person meals, and 1000 ml handles pasta or combo meals. See our rice-grain lunch boxes and rectangular food containers.
Round bowls (300-4850 ml)
Round shapes hold soups and liquids best because pressure is spread evenly around the lid. 428-750 ml bowls fit soups and noodle broths; 1000-1750 ml serve salads and shared dishes; 2000-4850 ml basins are used for catering and family hot pots. Compare safety-lock round bowls with standard round bowls and basins.
Compartment containers
3- and 4-compartment boxes separate rice, protein and vegetables. Total capacity of 900-1200 ml is typical for meal prep programmes. Browse compartment meal prep containers.
Sauce and portion cups (1-4 oz)
1 and 1.5 oz cups for dressings, 2 oz for sauces, 3-4 oz for sides. Matching lids prevent leaks in transit. See PP sauce cups with lids.
Sizing tips for buyers
- Order lids and bodies in the same ratio and from the same factory so they seal correctly.
- Check carton dimensions against your pallet or shelf plan: a 650 ml box typically packs 150-300 sets per carton.
- Request samples in two adjacent sizes before committing to a container order.
