Which polymer is used to make food containers?

           Most of us have plastic food containers at home. These food containers are airtight and do not absorb moisture easily. A material called polypropylene is used to make such food containers. It is a thermoplastic polymer made of propylene monomers and is also known as PP. Polypropylene doesn’t absorb water and dries quickly. It is an effective insulator and does not transfer heat. PP is also resistant to acids and alkalies.

           A range of other products like bottles, various parts of automobiles, plastic hinges, carpets and clothing use polypropylene.
