Application Scenarios of CPET Trays

CPET (Crystalline Polyethylene Terephthalate) trays, with a wide temperature resistance range of -40℃ to 220℃, excellent structural stability, and food contact safety, have become the preferred packaging solution for scenarios requiring both low-temperature storage and high-temperature heating. They are widely used in food packaging across multiple industries, with core application scenarios as follows:

I. Ready-to-Eat Food Sector (Frozen/Oven-Ready Types)

As the core packaging for frozen ready-to-eat meals and oven-compatible meals, CPET trays can directly carry food through the entire process of "frozen storage - oven/microwave heating" without the need for container replacement. For example, products such as quick-frozen dumplings and pre-cooked meal kits can be taken directly from the refrigerator and placed in an oven at 180-220℃ or a microwave for heating. This not only avoids contamination and loss during food transfer but also simplifies cooking steps, making it suitable for modern fast-paced household and office scenarios.

II. Bakery and Confectionery Packaging Sector

In the packaging of bakery products such as cakes, pies, and egg tarts, as well as confectioneries like chocolates and fudges, CPET trays serve a dual function of "baking mold + finished product packaging". During the baking stage, they can be directly used as molds to hold batter, withstanding high oven temperatures and ensuring uniform molding. After the finished products cool down, there is no need for demolding—they can be directly sealed with a lid and enter the retail link. This reduces labor costs and product damage rates during the traditional "mold-to-packaging" conversion process. Meanwhile, transparent CPET trays can clearly display the color and shape of bakery products, enhancing shelf appeal.

III. Pre-Cooked Food and Takeaway Sector

For pre-cooked dishes and takeaway meals from restaurants, chain catering, and group meal enterprises, CPET trays meet the needs of "standardized portioning + convenient heating". For example, Chinese fast food such as Kung Pao Chicken and Western light meals like pasta sets can be individually packaged in CPET trays, with easy-tear sealing films to lock in freshness. After receiving the meals, consumers can heat them directly without pouring them out, solving problems such as "heating deformation" and "odor emission" of traditional takeaway boxes while improving dining convenience.
