| 1 | Match the container to the portion size | Choose a container that leaves a small amount of headspace without allowing food to move excessively during transport. | 250–500 mL for snacks, side dishes, sauces, and small portions | Desserts, fruit, fries, salads, dips, and individual side dishes | Compare internal capacity rather than relying only on external dimensions. |
| 2 | Select a size for main meals | Use medium or large containers with enough width and depth for complete meals. | 700–1,200 mL for standard takeaway meals | Rice dishes, pasta, noodles, curries, stir-fries, and combination meals | Check whether the container can hold the meal without compressing toppings or side items. |
| 3 | Choose a shape that suits the food | Rectangular containers maximize stacking and compartmentalization; round containers work well for soups and liquid foods. | 500–1,000 mL, depending on the menu item | Rectangular: meals and sides; round: soups, stews, sauces, and salads | Consider portion presentation, storage space, and compatibility with delivery bags. |
| 4 | Use compartments when separation matters | Select two- or three-compartment designs for foods that should remain separate. | 700–1,000 mL total capacity | Main course with vegetables, rice with curry, salads with toppings, and combo meals | Make sure dividers are high enough to reduce mixing and liquid transfer. |
| 5 | Choose the right closure design | Use snap-lock lids for general meals, tight-fitting lids for liquids, and tamper-evident closures for delivery security. | 250–1,200 mL | All takeaway categories, with leak-resistant designs preferred for wet foods | Test the lid on a filled container and check all corners or locking tabs. |
| 6 | Match the material to temperature and food type | Choose food-contact packaging rated for the intended hot, cold, greasy, or acidic foods. | Available across snack, meal, and catering sizes | Hot meals, chilled salads, oily foods, soups, and refrigerated products | Review temperature limits, microwave or freezer suitability, and applicable food-contact compliance. |
| 7 | Check stacking, transport, and storage efficiency | Prefer stable, stackable containers with consistent footprints and lids that do not slip during delivery. | 500–1,200 mL for most delivery orders | High-volume takeaway service, catering, meal delivery, and food preparation | Measure storage shelves, delivery bags, and cartons before placing a bulk order. |
