Plastic bottles were first used commercially in 1947, but remained relatively expensive until the early 1950s when high-density polyethylene was introduced. [5] They quickly became popular with both manufacturers and customers because compared to glass bottles , plastic bottles are lighter, cheaper and easier to transport.
High-density polyethylene bottles introduced and soon replace glass bottles in most applications [11] 1965: Kevlar developed at DuPont by Stephanie Kwolek: 1980s: Polyester film stock replaces cellulose acetate for photographic film and computer tapes. 1988: First polymer bank notes issued in Australia
[9] [10] One recent life cycle study of one-way recyclable HDPE bottles indicated the importance of secondary packaging: returnable plastic crates can allow lower tare weight bottles. [11] Reuse of bottles requires a reverse logistics system, cleaning and sanitizing bottles, and an effective quality management system. A key factor with glass ...
PepsiCo introduced the first two-liter sized soft drink bottle in 1970. [1] Motivated by market research conducted by new marketing vice president John Sculley (who would later be known for heading Apple Inc. from 1983 to 1993), [2] the bottle and the method of its production were designed by a team led by Nathaniel Wyeth of DuPont, who received the patent in 1973.

It is estimated that 3.4 billion tonnes of plastic packaging were created between 1950 and 2017. [1] Most plastic packaging is disposed of within a relatively short time. Discarded packaging accounts for 46% (158 million tonnes) of total annual plastic waste generation. Most plastic packaging waste is estimated to come from household waste.
Polythene is the world's most widespread polymer, and was first produced by ICI from 1939; many plastic bottles are made from LDPE. Polystyrene was invented in Germany in 1937. PTFE was discovered in America (New Jersey) in 1938 by Roy J. Plunkett when at DuPont. PET beverage bottles were introduced from 1973. PEEK was developed by ICI in 1977.

Smaller particles assumed to be plastic but not positively identified were found as well – an average of 314 per litre. [96] In 2008, researchers from Arizona State University found that storing plastic bottles in temperatures at or above 60 °C can cause antimony to enter the water contained in the bottles. Therefore, frequently drinking ...
