Heat Resistant CPET Tray for Safe Food Packaging

Heat resistant PET trays are specialized trays made from a modified version of PET (polyethylene terephthalate) designed to withstand elevated temperatures, beyond the capabilities of standard PET. While standard PET softens at relatively low temperatures, heat resistant PET can tolerate temperatures up to 250–300°F (121–149°C), making them suitable for applications like microwave heating, warm food storage, and light oven use (depending on the specific formulation). This heat resistance expands their functionality, allowing them to hold hot foods such as freshly cooked meals, soups, stews, and baked goods without warping, melting, or releasing harmful substances. These trays maintain the inherent benefits of PET—clarity, rigidity, and lightweight construction—while adding thermal durability. Their transparency allows consumers to easily view the contents, enhancing product appeal in retail settings, while their rigid structure ensures they can hold food securely during transport and handling. Heat resistant PET trays feature raised edges to contain liquids and prevent spills, and many are designed to be stackable for efficient storage. They come in various sizes, from small trays for individual snacks or hot beverages to larger trays for family-style meals. Additionally, they are often freezer-safe, enabling them to transition from cold storage to heating without damage. As a food-grade material, heat resistant PET is BPA-free and compliant with strict safety standards, ensuring it is safe for direct contact with hot food. These trays are widely used in foodservice for takeout, in convenience stores for hot snacks, and in retail for pre-packaged meals that require heating. Heat resistant PET trays offer a versatile solution, combining the visual appeal of PET with the practicality of thermal durability for hot food applications.
