Clear polypropylene dome lid fits the 1 compartment CF1948 and 2 compartment CF1940 2 oval bases. The Crisp Food Technologies Containers and Lids use an exclusive, convection cross flow technology design to relieve moisture and condensation, while maintaining product temperature. Through the closure ventilation, along with raised airflow channels in the base of the container, combined with venting in the anti fog lid, ensure that fried foods remain crispy. The unique design of this packaging system retains internal temperatures better than other rigid containers currently in use for fried foods. As in all Culinary Series containers, it is designed to withstand temperatures to 230°F in warming unit displays, under heat lamps and in the microwave. Independent, side by side tests at several leading retailers and restaurant chains demonstrate that the Crisp Food Technologies Containers preserved temperature and texture of fried foods longer than competitive materials during 30 minute delivery. It also outperformed the other fried chicken containers in the Supermarket Deli hot case: Better texture, better temperature retention, better tasting fried foods. The package holds hamburgers and fries, several pieces of fried chicken, as well a variety of other fried food items. Made of polypropylene (Number5PP), and is microwave safe, dishwasher safe, consumer reusable and eligible for recycling.
