Question

Explain why plastic containers are favored for food storage?

Answer 1

Hint: Plastics are polymers which are broadly classified into thermoplastic and thermosetting plastic. These are inert and insulator and safe for use.

Complete step by step answer:
Plastics are chemically polymers. A polymer is a macromolecule that is formed by joining many smaller molecules called monomers together. The process of making polymer is called polymerization. Polymers are popularly known as plastics. Depending upon the types of polymers and the method of polymerization, a polymer or a plastic can be classified into thermoplastic and thermosetting plastic. Both types of plastics are used for making containers for food storage. Though thermosetting plastics are non- non-recyclable and harmful for the environment, plastic has many other advantages over metals and wooden utensils. Hence plastic containers are very popular for food storage.
Some of main properties of plastic are given below:
1. They are cheaper.
2. They can easily be converted into different shapes.
3. They are lightweight and easily portable.
4. They have high tensile strength.
5. They are not attacked by insects, rats, moths etc.
6. They are washable.
7. They are insulators and protect from electrocution.
8. They are chemically inert.
9. They are tear and wear free.
10. They do not corrode.

Besides the above mentioned characteristic properties, plastic containers have some more favorable properties like, plastic containers do not react with food material kept in it. They save energy consumption when used in the refrigerator. They allow direct heating of food in a microwave. If a metal container is used it will absorb heat itself so more energy would be needed.
Seeing all these favorable properties plastic containers are favored for food storage.

Note:
Plastic containers have many properties that make them popular for food storage. They do not react with food items kept in it. They do not conduct electricity hence save energy. They are long lasting and light weight. Hence durable, safe and easy to use.
