High-Temperature Resistant Blister Products
High-temperature resistant blister products, crafted with CPET core material, offer outstanding heat resistance. They can be directly placed in ovens or microwaves for high-temperature heating, withstanding a broad range of temperatures. Under high heat, they do not shrink, deform, or release harmful substances, maintaining strong structural integrity. Simultaneously, they exhibit excellent low-temperature resistance, allowing direct heating after frozen storage without requiring packaging replacement throughout the process. This makes them suitable for the entire cold chain, storage, and heating workflow. The products feature an excellent finished texture, effectively locking in freshness and flavor to preserve food quality. All meet food contact safety standards for added peace of mind. Customizable in multiple sizes and shapes—including blister trays and meal containers—they serve diverse high-temperature packaging needs across scenarios such as pre-cooked meals, baked goods, airline catering, instant foods, and other ready-to-heat-and-eat food packaging.
