Answer 2

Answer:

1)If the number is ‘1’ inside the triangle it means that the plastic is made of Polyethylene Terephthalate (PET)

Generally, these are used to make bottles for soft drinks, water, juice, sports drinks etc. It is safe for one-time use and these bottles should never be heated. This kind of plastic degenerates itself over the time. It is not safe to use it after the expiry date so they come up with the message – Crush the bottle after use.

2. If the triangle has the number ‘2’ in it then the plastic is made of high-density Polyethylene (HDPE)

This plastic is commonly used for shampoo, detergent containers and grocery bags.

3. If the triangle has the number ‘3’ in it then the plastic is made of Polyvinyl Chloride.

This type of plastic contains carcinogens and are used for peanut butter jars, plastic toys, tablecloths etc.

4. The plastic bottles that have the number ‘4’ are made up of low-density Polyethylene (LDPE) and are reusable all the way.

This type of plastic is used to make shopping bags, newspapers, hot and cold beverage cups etc.
