Question

why plastic floats on water..? ​

Answer 1

Answer:

There are different types of plastic, with different density.

HDPE ( high density polythene) , LDPE( low density polythene) , and PP( polypropylene ) which makes up the containers and plastic bags for example do float, as their density is less than that water. Higher density plastics such as PET ( polyethylene terephthalate) , PVC (polyvinyl chloride) and PS ( polystrene solid ) , do sink.
