Contact-clear and microwavable, Pro-Kal containers are round deli tubs made of durable polypropylene. A lightweight and cost-effective plastic hot and cold filling food packaging choice. Recessed plug-fit and overcap lid (printable) compatibility for presentation and application flexibility. Made with material that is microwave safe so you don't have to transfer to another container or dish to reheat. Insusceptible to flavor or odor transfer. One lid diameter fits 6 Pro-Kal containers for fewer SKUs to distribute and stock (Lids Sold Separately). Large, flat and uninterrupted labeling space for strong branding opportunities. Smooth rolled rims for leak resistant snap-fit lid application and removal. Microwave-safe polypropylene withstands temperatures of 0F up to 240F.
