For storing food in the fridge or freezer as well as transporting a meal, it is always practical to have an airtight box. Many households have therefore adopted the plastic box in the kitchen for greater practicality. However, like a toothbrush or a sponge, Tupperware is not eternal.

To cook and store food safely, here are the signs of wear and tear to look out for.
