CPET Microwave Tray: High-Temp Food Packaging Solution

CPET microwave trays are specialized containers made from crystallized PET (CPET), a material uniquely suited for microwave heating due to its exceptional heat resistance and stability. Unlike standard plastics that may warp, melt, or release harmful chemicals when exposed to microwave radiation, CPET can safely withstand the high temperatures generated in microwaves—typically up to 250°F (121°C) or higher—making these trays ideal for heating prepared meals, leftovers, and convenience foods. The trays are designed with a rigid structure that maintains its shape during heating, preventing spills and ensuring even distribution of heat throughout the food. This even heating helps avoid cold spots, ensuring the food is thoroughly warmed. CPET microwave trays often feature raised edges to contain sauces, liquids, and food items, and some include ventilation holes in the lid (if applicable) to release steam, preventing pressure buildup and splatters inside the microwave. They come in various sizes, from small trays for individual snacks or side dishes to larger trays for main courses like pasta, rice dishes, or frozen dinners. The material is also freezer-safe, allowing users to store food in the same tray before microwaving, eliminating the need for transfer between containers. As a food-grade material, CPET is BPA-free and compliant with strict safety regulations, ensuring no harmful substances leach into food during heating. These trays are widely used in retail for pre-packaged microwaveable meals, in restaurants for takeout that needs reheating, and in households for convenient meal preparation. CPET microwave trays offer a safe, efficient, and convenient solution for heating food, combining functionality with peace of mind for both manufacturers and consumers.
