Give reasons why plastic containers are used as storage devices?

Plastic containers are used as storage devices since they are

a) Light, Cheap and Durable – Easy to handle and last longer.

b) Cost effective – They cost less compared to metal containers.

c) Inert Nature – Plastic containers are chemically inert since they do not react with the other substances. In case of metal containers, a substance placed inside reacts with the metal and forms a different substance.

d) Insulator - Plastic is the bad conductor of heat so the food kept in it remains hot for longer period of time.
