PET bottles are bottles made-up of a plastic resin chemically known as polyethylene terephthalate and abbreviated as PET. Due to some inherent properties of PET resin, these bottles are transparent, light-weight, high in strength and impermeable to carbon dioxide. Their manufacturing is based on a stretch blow-molding process, which provides strength and high resistance to bear internal pressure and enables them to be stacked like glass bottles. Unlike other plastic containers that use PP or HDPE or PVC; PET bottles have no shortcomings of leaving residues, translucency and non-recyclability.

Primarily used in the packaging of water and beverages, PET bottles are also gaining shares in other industries like- juices, salad dressings, household cleaners, medicines, dish detergents, mouthwashes, etc. Being light in weight and easy to handle, they are preferred in the packaging of carbonated soft drinks (CSD’s) and are continuously replacing glass bottles due to their tendency to break and the inconvenience created while returning them after consumption. As a result of an increasing demand for bottled beverages and replacements of glass and metal containers with PET bottles, the global consumption of PET bottles is expected to show a continuous growth in the short and medium terms.
