The Ultra•Seal™ container line offers an assortment of Ultra•Seal™ containers to provide solutions for everyday food storage needs. The boxes feature a color-coded matching system to help find the correct lid and base combination without rummaging through the cupboards. The gasket and four latches in the lid create an airtight and watertight seal that keeps food fresh and prevents liquids from leaking. A vent in the lid releases steam when the container is placed in the microwave. All boxes store efficiently both when in use and not. All Ultra•Seal™ containers are freezer, microwave, and dishwasher safe, as well as BPA-free and phthalate-free.
