Material comparison
CPET vs APET
Both are PET-based tray materials. CPET is crystallised for heat resistance (ovenable, dual-oven meal trays); APET is amorphous, glass-clear for cold packaging.
CPET vs APET — side by side
| CPET | APET | |
|---|---|---|
| Heat resistance | High — ovenable (to ~220 °C) | Low |
| Clarity | Opaque (often black) | Glass-clear |
| Typical use | Ready-meal / ovenable trays | Cold food trays, blisters, lids |
| Cost | Higher | Lower |
Choose CPET when…
- Ovenable and dual-ovenable ready-meal trays
- Hot food that goes oven/microwave-to-table
Choose APET when…
- Cold, glass-clear food and retail packaging
- Blisters, lids and clear trays
The verdict: Choose CPET for ovenable ready-meal trays that take heat; choose APET for cold, glass-clear packaging. The service temperature decides.
Frequently asked
Can APET go in the oven?
No — APET is a cold-use clear material. For ovenable trays use crystallised CPET.
