plastic bottles are bottles made of plastic. Plastic bottles are commonly used to store liquids such as water, soft drinks, motor oil, cooking oil, medicines, shampoo, milk, and ink. The size ranges from very small sample bottles to large carboys.

History
Plastic bottles were first used commercially in 1947 but remained relatively expensive until the early 1950s when high density polyethylene was introduced. They quickly became popular with both manufacturers and customers due to its light nature and relatively low production and transportation costs compared to glass bottles. However, the greatest advantage that plastic bottles have over glass is their superior resistance to damage, both in production and transportation. Except for wine and beer, the food industry almost completely replaces glass bottles with plastic bottles.

Production
There are ongoing concerns about the use of plastics in consumer packaging solutions, the environmental impact of disposal of these products, as well as concerns about consumer safety. Karin Michaels, Associate Professor at Harvard Medical School, points out that toxins absorbed from plastics may be associated with disorders such as infertility and cancer in humans.
In the United States, plastic water bottles are regulated by the FDA which also checks and collects samples of bottled water plants regularly. Plastic water bottle factories have low priority for inspection because of continuous good safety record. In the past, the FDA maintains that there is a lack of human data showing plastic causes health problems, but in January 2010, the FDA reversed its opinion saying they now have concerns about health risks. An article published on November 6, 2017 in Water Research reports on microplastic contents in mineral waters packaged in plastic bottles or glasses, or cartons of beverages. In 2018, research conducted by Sherri Mason of the State University of New York in Fredonia revealed the presence of polypropylene, polystyrene, nylon and polyethylene terephthalate microparticles in plastic bottles. Polypropylene is hereby found to be the most common polymer material (54%) and the second most abundant polymer nylon (16%). The study also mentioned that polypropylene and polyethylene are polymers that are often used to make plastic bottle caps. Also, 4% of the plastic particles taken were found to have signs of industrial lubricants lining the polymer. The study was reviewed by Andrew Mayes of the University of East Anglia (UAE) School of Chemistry. The European Food Safety Authority suggests most of the microbes are excreted by the body, but the UN Food and Agriculture Organization warns that it is possible that the smallest particle (& lt; 1.5? M) can enter the bloodstream and organs, through the intestinal wall.
Label
The plastic bottle is marked basically with a resin identification code to indicate the material used.
