Question
Explain why, plastic containers are preferred for storing food.
✓
Answer
Plastic is a polymer like a synthetic fibre. The arrangement of units in a plastic can be linear or cross$-$linked. Plastic containers are preferred for storing food because of the following reasons:
$-$Plastic is non$-$reactive. It does not react with water and air. It is therefore, safe to keep food in plastic containers.
$-$Plastic is light, strong and durable and can be molded into different shapes and sizes. It is cheaper than metals. It is widely used in making household items including food containers.
$-$Plastics are poor conductors of heat and electricity and can be used for making handles of frying pans.
