Revealing the “high-energy materials” behind airline catering – thermoformed CPET plastic sheets
Airline catering needs to cope with the special environment of 10,000 meters above sea level:
- -50℃~220℃ extreme temperature difference (refrigerated storage + on-board oven heating)
- High strength and pressure resistance (avoid deformation during transportation)
- Lightweight (every 1kg weight reduction saves more than 10,000 yuan in fuel costs per year)
- Food safety certification (FDA/EC standard)
Traditional plastics (such as PP, PS) are difficult to meet these requirements, and CPET (crystallized polyethylene terephthalate) is becoming an ideal choice for airline meal boxes due to its superior performance.
High temperature resistance up to 220°C, suitable for the entire heating process
CPET sheets have excellent heat resistance and can be used safely in the temperature range of -40°C to 220°C, suitable for: Microwave heating, Hot air circulation oven, Steam insulation cabinet.
The whole process from cold chain storage to heating and distribution can be completed without transferring containers, greatly improving meal distribution efficiency and reducing the risk of cross contamination.
Stable in frozen storage, not easy to break
Airline catering generally adopts cold chain transportation. CPET has good impact resistance. Even if it is frozen for a long time at -40°C, it is not easy to break or deform, ensuring the integrity and safety of food packaging during transportation.
Food contact safety, environmentally friendly and recyclable
CPET materials meet the food contact safety standards of the European Union (EU) and the US FDA
Contains no harmful substances, has no odor, and does not release toxic components after long-term heating
Can be sorted and recycled after use, supporting airlines’ environmental protection and carbon reduction goals
Excellent thermoforming performance, suitable for mass production
CPET plastic sheets are suitable for high-speed automatic thermoforming equipment
Uniform thickness, stable molding, smooth edges
Can be customized in a variety of sizes, depths and colors (commonly black or white)
From mold design to mass production, it greatly improves the efficiency and consistency of the airline catering supply chain.
Wide range of application scenarios
Airline catering boxes (staple food boxes, side dishes boxes, dessert boxes)
Hot food packaging containers for trains, ships, hospitals, cold chain takeout, etc.
High-end convenience store lunch boxes, instant food heating boxes
Safety, heat resistance, recyclability, efficient production, CPET sheets have become the industry’s first choice for airline meal boxes. Whether at an altitude of 10,000 meters or prefabricated distribution on the ground, CPET always ensures food safety and convenience.
