8.5x5.75x1.38" UltraBakeables Crystallized Polyethylene Terepthalate (CPET) containers can be used for virtually any food packaging application: shelf stable, bakery, HMR, refrigerated and frozen food. Our CPET containers are ready for use in either microwave or conventional ovens, are conducive to high-temperature performance (less warping and distortion) than competitors' products due to our melt-to-mold process CPET containers provide comparable shelf life to PP/EVOH containers when used for refrigerated applications. They are impact-modified to improve crack resistance when used for frozen applications. Depending on the material formulation, our product provides five to 15 times the impact strength of non-impact modified CPET. Goes from -40 degrees to 400 degrees. Bake, seal, sell in the same containers. Microwavable and Ovenable. From the Freezer to the Oven to your table. Excellent Oxygen Barrier Properties
