(a) Plastic bags, thermo Cole sheets, foam sheets, paper bags, etc. are the various kinds of packaging materials collected. These packaging materials are used to protect the household articles, food items or other goods while transporting from one place to another.
(b) Packaging used for food-items, gifts, chocolates, toys, clothes, shoes, etc., can be reduced.
(c) Unnecessary packaging increases the amount of garbage. Generally, when a package is opened, the things packed inside it is used while the packaging material is thrown. People throw the packaging materials on the streets which causes pollution as some of these packaging materials cannot be disposed off easily.
