CPET Ready Meal Tray
What Is a CPET Food Tray?
CPET means crystalline polyethylene terephthalate. During production, PET sheet is crystallized and thermoformed so that the finished tray can maintain its shape at temperatures much higher than standard APET packaging.
CPET trays are commonly called dual-ovenable trays because an approved tray can be used in both a conventional oven and a microwave oven. They are also suitable for chilled and frozen storage, allowing food producers to fill, seal, freeze, distribute, reheat and serve the meal in the same package.
Important: Actual heating performance depends on the tray design, food load, oven type, time, temperature, lidding system and validation. CPET trays should not be used under a broiler, on a stovetop, over an open flame or in direct contact with heating elements unless specifically tested.

Key Benefits of CPET Food Trays
1. Dual-ovenable performance: Approved CPET trays can be used in microwave and conventional ovens, allowing consumers to reheat or cook food without transferring it to another container.
2. Freezer-to-oven convenience: The tray can support chilled or frozen distribution and subsequent reheating in the same package.
3. Dimensional stability: CPET retains rigidity during filling, freezing, transport and heating when the tray is correctly designed.
4. Grease and moisture resistance: CPET performs well with sauces, oils, meat juices and prepared foods under validated conditions.
5. Reliable tray sealing: A flat and consistent flange can support peelable or lock-seal lidding film for leak control and tamper evidence.
6. Stackability: Nested empty trays save storage space, while filled trays can be designed for stable stacking and transport.
7. Custom meal presentation: Compartments, colors, embossing and shapes can be matched to retail, airline, catering or bakery programs.

Microwave and Conventional Oven Instructions
Microwave use: Follow the meal producer's instructions for time, power and venting. The lidding film may need to be pierced, peeled back or removed depending on its structure.
Conventional oven use: Place the tray on a baking sheet or oven rack as specified by the food producer. Do not exceed the validated temperature or heating time.
Frozen meals: Freezer-to-oven use must be validated for the exact food load, tray and lidding system.
Uneven heating: Meal composition, fill depth, sauces and microwave power can affect temperature distribution.
Restricted uses: Do not use under a broiler, in a toaster oven, on a grill, on a stovetop, over an open flame or directly against a heating element unless specifically approved.
Consumer labeling: Print clear storage, venting, heating and handling instructions on the package.
Lidding Film and Tray Sealing Options
The lidding film must be selected according to the tray flange, food type, storage condition, heating method, peel requirement and tray-sealing machine. A film that seals to one CPET tray may not provide the same peel or seal strength on a different tray formulation.
