A plastic bottle is a bottle made out of plastic. Plastic bottles are usually used to store liquids such as water, soft drinks, motor oil, cooking oil, medicine, shampoo, milk, and ink. The size ranges from very small sample bottles to large carboys.
Plastic bottles were first used commercially in 1947, but remained relatively expensive until the early 1960s when high-density polyethylene was introduced.
They quickly became popular with both manufacturers and customers due to their lightweight nature and relatively low production costs compared with glass bottles. Except for wine and beer, the food industry has almost completely replaced glass with plastic bottles.
There is an ongoing concern as to the use of some plastics in consumer food packaging solutions. The environmental impact of the disposal of these products, as well as concerns regarding consumer safety, are still debated.
Plastic water bottles are regulated by the FDA. The FDA periodically samples bottled water and also inspects bottled water plants. Plastic water bottle plants hold a low priority for inspection due to a continuously good safety record.
