Tupperware works by creating a sealed container for storing food. The top and bottom have grooves which align to keep the contents secure and fresh.
Cooking destroys or reduces the population of spoilage microorganisms on and in the food. It also deactivates enzymes which cause food to decompose.
It depends on the type of food and the type of Tupperware container but in general it limits the amount of air, contaminants, and condensation to which the food is exposed.
Keeping food in tight containers prevent them from getting oxidised...thus it prevent them from spoiling
Spoilt
Deforestation,GW etc
