PET bottles are more durable and breakage-resistant as compared to their glass counterparts. It is because of their tough non-reactive composition that prevents the creation of moisture and air; there are lesser chances of leakage and bursting while shipping from one place to another, thereby maintaining the quality of the liquid inside.
It consumes lesser power to manufacture PET bottles compared to glass containers. Also since plastic is lighter, the transportation costs involved are lesser.
