What are the advantages of using CPET trays for airline meal containers?

PET (Crystalled PET) trays are the mainstream choice for airline meal containers. Their core advantages are wide temperature tolerance, lightweight, ease of handling, safety and compliance, and recyclability, perfectly adapting to the entire process of airline meals from cold chain to in-flight heating.

I. Extremely Wide Temperature Tolerance (A Core Necessity for Airline Meals)

* Extremely High Temperature Resistance: Withstands temperatures from -40℃ to 220℃, allowing direct heating in ovens/microwaves without deformation or release of harmful substances.

* Extremely Low Temperature Resistance: Suitable for freezing at -40℃ and cold chain transportation, the container structure remains stable and does not crack.

* Suitable for the Entire Process: From central kitchen preparation → frozen storage → in-flight reheating → passenger consumption, no container replacement is required.

II. Lightweight and Space Efficiency (Key to Airline Operations)

* Lightweight: 50%+ lighter than metal trays, reducing aircraft weight and saving fuel.

* Stackable/Nested: Significantly improves the utilization of in-flight and ground storage space, facilitating bulk handling.

Structural Rigidity: Lightweight yet not easily bent, preventing spills during cabin turbulence.

III. Food Safety and Hygiene Compliance

Food-Grade Certification: Meets food-grade standards, BPA-free.

High Barrier Properties: Blocks oxygen and moisture, extending food shelf life and reducing the risk of spoilage.

Sealed and Leak-Proof: Compatible with heat sealing/coating, preventing soups and sauces from leaking, maintaining cabin cleanliness.

IV. Optimized Operation and Service Experience

Multi-Compartment Design: 1–4 compartments separate main dishes, side dishes, and staple foods, preventing flavor mixing and ensuring aesthetically pleasing presentation.

Easy to Open and Handle: Compatible with automatic sealing lines, making it easy for passengers to tear the film; non-slip surface provides a more stable grip.

Clean Appearance: Smooth, scratch-resistant surface maintains a clean and professional visual appearance throughout.

V. Sustainability and Cost Advantages

100% Recyclable: PET#1 grade, with a mature recycling system, allowing for the recycling of food-grade trays.

Durable and Robust: Drop-resistant and oil-resistant, less prone to damage, reducing losses and replacement costs. Automation Compatible: Compatible with high-speed packaging lines to improve meal preparation efficiency.
