Short answer: use kraft paper bowls for salads, poke and noodles; clear PET containers for cold, visual foods like fruit, desserts and sandwiches; and aluminium foil containers for hot meals that need oven reheating or heat retention.
Kraft paper bowls
PE- or PLA-coated paperboard resists grease and moisture, holds hot or cold food and signals a natural, paper-first brand. Pair with a PP lid for hot soups or a clear PET lid for salads.
Clear PET containers
PET shows off food — essential for grab-and-go fridges. Clamshells and compartment boxes keep items separated. PET is for cold or room-temperature foods only.
Aluminium foil containers
Foil goes from freezer to oven, keeps food hot and is infinitely recyclable. Board lids are printable and insulate better; clear lids show the food but must be removed before heating.
Comparison
| Requirement | Kraft paper | PET | Aluminium |
|---|---|---|---|
| Hot food | Yes | No | Yes, oven-safe |
| Visibility | With clear lid | Excellent | With clear lid |
| Leak resistance | Good | Good | Very good (crimped lid) |
| End of life | Paper / compost (PLA) | Recycling | Recycling |
Don't forget the small items
Most delivery complaints come from sauces. Use portion cups with tight lids, and choose PP for hot sauces.
Frequently asked questions
Can kraft paper bowls hold hot soup?

Are aluminium foil containers microwave safe?
Generally no — use them in conventional ovens. Some microwave-specific foil trays exist; follow the manufacturer's guidance.
