1CP CPET Trays

1 Compartment CPET Trays Manufacturer for Ready Meals

HSQY supplies 1 compartment CPET trays for frozen ready meals, chilled prepared foods, airline catering, bakery products, central kitchens, meal delivery, institutional catering and industrial food production. The current category extends from compact 6–15 oz portion trays to 88 oz and 118 oz large-format food containers.

Crystallized polyethylene terephthalate provides the thermal stability needed for workflows that may include filling, heat sealing, chilling or freezing, transportation, microwave reheating, conventional oven reheating and direct serving. Selected HSQY models are published for approximately -40°C to +220°C, subject to validation of the exact tray, food, lidding film and heating process.

Quick answer: A 1CP CPET tray has one uninterrupted food cavity, making it suitable for pasta, rice, casseroles, curries, meat dishes, desserts and family-size prepared foods. Compared with a divided tray of the same external size, a single-compartment tray normally provides more usable volume and a simpler filling process.

How to Select the Correct Capacity and Depth

Nominal ounces are comparison values, not the final usable fill volume. Food density, sauce level, headspace, flange clearance and heating instructions determine the correct tray.

Record meal weight: Include minimum, target and maximum portions.
Measure food volume: Equal weights of rice, vegetables and sauce occupy different volumes.
Define headspace: Leave room for sealing, steam and transportation.
Check food shape: Whole meat portions and casseroles use the cavity differently.
Protect the flange: Keep oil, food and sauce away from the seal area.
Validate heating: Deep trays and large portions may require longer heating.
Confirm equipment fit: Check fillers, sealing tools, cartons, ovens and retail shelves.

Freezer-to-Oven and Microwave Performance

Selected HSQY models are published for approximately -40°C to +220°C. This material range is not an unrestricted consumer instruction. The final process must define the tray, food, storage condition, heating equipment, power or temperature and maximum time.

Use the actual food recipe and fill weight.
Include oil, sugar, salt, acid and alcohol content.
Test the longest frozen storage period.
Run the actual microwave or oven instruction.
Inspect the base, corners and flange for distortion.
Measure food center temperature and heating uniformity.
Confirm safe handling immediately after heating.

Can CPET Trays Be Used Under a Grill or Open Flame?

No. CPET trays should not contact open flames, broiler elements or uncontrolled radiant heat. Maintain the required distance from heating elements.

Can the Lidding Film Stay on During Heating?

Only when the exact film is designed and validated for the heating process. Some films must be removed, pierced or vented before use.

CPET Lidding Film and Heat-Sealing Compatibility

HSQY supplies related sealing film for CPET ovenable trays. The tray, lidding film and sealing machine must be tested as one packaging system.

Film Requirement	Function	Validation
Sealant Compatibility	Bonds to the CPET flange	Seal initiation and operating window
Easy Peel	Controlled consumer opening	Average and peak peel force
Weld Seal	Higher seal retention	Opening method and integrity
Ovenable Film	Stays attached during defined heating	Venting, shrinkage and seal stability
Anti-Fog Film	Maintains chilled product visibility	Condensation after cooling and storage
Printed Film	Branding, instructions and traceability	Ink, registration and barcode readability

How to Build a Reliable Sealing Window

Confirm the exact tray mold, color, weight and flange dimensions.
Select the required easy-peel or weld-seal film.
Inspect the flange for food, oil, sauce, scratches and distortion.
Adjust temperature, pressure and dwell time systematically.
Measure seal strength after chilling, freezing, transport and heating.
Use an approved package-integrity or leak test.
Validate the settings at the intended commercial line speed.

Can 1CP CPET Trays Be Used with MAP?

Some CPET trays can be integrated into modified atmosphere packaging, but CPET does not automatically mean high gas barrier. A MAP-ready package requires a tray, lidding film and seal that meet the oxygen-transmission and gas-retention specification.

Define the food, gas mixture, residual oxygen, headspace, target shelf life, storage temperature, OTR and integrity test. Shelf life must be established using the actual food and cold-chain process.

Automatic Filling and Tray-Sealing Line Compatibility

Denesting: Confirm trays separate without double picks or jams.
Conveyor stability: Check base geometry and guide-rail alignment.
Filling accuracy: Control portion weight, splash and headspace.
Tooling fit: Verify flange dimensions, corner radii and cutting profile.
Film tracking: Validate tension, registration and cut accuracy.
Cycle speed: Confirm stable seal quality at commercial throughput.

1CP CPET vs Other Food Tray Materials

Material	Heating and Storage	Main Advantage	Limitation
CPET	Qualified freezer, microwave and oven use	Dual-ovenable performance and rigidity	Variable recycling access
PP	Microwave and freezer applications	Low weight and cost efficiency	Lower typical oven-temperature range
APET	Cold and ambient packaging	Clear product visibility	Not intended for high-temperature oven use
Aluminum	Strong conventional oven performance	Fast heat transfer	Generally unsuitable for standard microwaves
Ovenable Fiber	Depends on board and coating	Paper-based presentation	Barrier and seal depend on coatings

Food-Contact Safety, Recycling and Sustainability

Food-contact suitability must be confirmed for the exact CPET resin, pigment, recycled-content level, lidding film and intended heating conditions. Request documentation for the final tray model and destination market rather than relying on a general statement about CPET.

CPET is PET-based and may contain recycled PET where the formulation and food-contact rules permit it. Actual recyclability depends on whether local systems accept opaque or crystallized PET trays. Color, labels, film, adhesives and food residue affect recovery.
