CPET

CPET is a special type of plastic designed to handle high heat. Unlike regular plastic containers, CPET trays can safely go from freezer to oven without warping or melting. This makes them ideal for frozen meals, ready-to-eat dishes, and other food applications that need oven-safe packaging.

This material offers several practical benefits. It maintains its shape and strength even at high temperatures, provides a stable base for food presentation, and can be formed into various tray designs. CPET trays are also lightweight and offer good insulation properties.

At BlissPak, we understand the specific needs of food packaging. The CPET we supply meets strict food safety standards and performs reliably in demanding temperature conditions. Whether you need trays for frozen dinners or oven-ready products, BlissPak provides material solutions that support both food safety and convenience.

CPET FAQs

1. What makes CPET different from regular PET plastic?

CPET is specially crystallized to withstand high temperatures, while regular PET softens around 70°C. This makes CPET suitable for oven use up to 220°C, unlike standard PET packaging.

2. Can CPET trays go directly from freezer to oven?

Yes, CPET maintains dimensional stability across extreme temperature changes. This freezer to oven capability makes it ideal for frozen ready meal packaging.

3. Is CPET safe for food contact at high temperatures?

CPET is manufactured to meet food contact safety standards for high-temperature applications. It does not release harmful substances when used within specified temperature ranges.

4. What types of food packaging commonly use CPET material?

CPET is primarily used for dual ovenable trays for frozen meals, bake and serve containers, and ready to eat food packaging where heat resistance is essential.

5. CPET is primarily used for dual-ovenable trays for frozen meals, bake-and-serve containers, and ready-to-eat food packaging where heat resistance is essential.

CPET offers better microwave compatibility, lighter weight, and often more cost-effective production than aluminum, while providing similar oven performance for many applications.

You may want to know about CPET

BlissPak's CPET plastic sheets are engineered for outstanding thermal stability and robust thermoforming performance, making them the ideal material for high-temperature packaging applications. Designed specifically for thermoforming and blister production, CPET combines rigidity, heat resistance, and dimensional stability to meet the demands of food, electronics, and industrial packaging that require reliable performance under extreme temperatures.

Excellent High-Temperature Resistance

As a crystallized PET material, CPET stands out for its exceptional heat resistance. It can withstand high-temperature environments without warping, softening, or deforming, making it fully suitable for oven-ready food trays, microwave-safe packaging, and industrial components that experience thermal processing. This unique characteristic sets CPET apart from standard PET and PS materials, and perfectly matches BlissPak's packaging solutions for heat-exposed applications.

Stable & Precise Thermoforming Performance

Our CPET sheets are specially formulated for efficient thermoforming processing. They heat uniformly, form clean contours, and maintain excellent dimensional stability during and after production. Even in deep-drawn designs and complex cavity shapes, CPET forms consistently with minimal shrinkage, ensuring every finished blister or tray matches mold specifications accurately. This stability supports high-yield production on BlissPak's automated thermoforming lines, reducing waste and improving overall efficiency.

Strong Rigidity & Durable Protection

CPET offers higher rigidity and structural strength compared to standard PET sheets. Thermoformed CPET packages hold their shape securely during transportation, stacking, and handling, providing reliable protection for food products, electronic components, and delicate hardware. Its sturdy nature reduces damage during logistics and enhances the overall safety and integrity of packaged goods.

Safe for Food & Wide Industrial Use

CPET is widely recognized as a safe food-contact material, compliant with global food safety standards. It is odorless, non-toxic, and does not migrate harmful substances, making it widely used in ready-to-eat meals, airline food trays, frozen food packaging, and fresh produce containers. Beyond food applications, CPET also serves electronics, automotive, and industrial packaging due to its stable physical properties and reliable performance.

Clean Appearance & Professional Presentation

BlissPak's CPET sheets offer a smooth, clean surface and consistent finish, supporting a professional and high-end appearance for finished packaging. Whether transparent or opaque, CPET maintains a neat visual effect after thermoforming, enhancing product display and brand image for retail and commercial use.
