If you like preserving your food so that it is as fresh when you reopen it as it was when you first stored it in your freezer, you need a good Tupperware set. Tupperware is an excellent group of storage containers that can be refrigerated, stored at room temperature, and sometimes microwaved.
The containers that can withstand microwaving are made to resist distortions caused by heat. All Tupperware is made to last through repeated use for decades. These tough containers are great at holding liquid or partially liquid foods and the covers are tight enough to prevent leaking even when stored upside down.
The brand name, Tupperware is renowned for its toughness and durability. After multiple uses, you will still have a usable storage container that will prevent the entry of air that could allow mold to grow or spoilage to occur.
