The first plastic made from synthetic components, it was developed by Leo Baekeland in Yonkers, New York, in 1907, and patented on December 7, 1909. [3] Bakelite was one of the first plastic-like materials to be introduced into the modern world and was popular because it could be moulded and then hardened into any shape.
In the plastic-polluted waters of the Sargasso Sea, bacteria have been found that consume various types of plastic; however, it is unknown to what extent these bacteria effectively clean up poisons rather than simply release them into the marine microbial ecosystem. Plastic-eating microbes also have been found in landfills. [96]

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.
Plastic used in agriculture was expected to include 6.7 million tons of plastic in 2019 or 2% of global plastic production. [1] Plastic used in agriculture is hard to recycle because of contamination by agricultural chemicals. [ 1 ]
Today's Saran Wrap is no longer composed of PVDC in the United States, due to cost, processing difficulties, and health and environmental concerns with halogenated materials, [1] and is now made from polyethylene. [12] [13] [14] However, polyethylene has a higher oxygen permeability, which in turn affects food spoilage prevention.
Parkesine, the first member of the Celluloid class of compounds and considered the first man-made plastic, is patented by Alexander Parkes. [4] 1869: John Wesley Hyatt discovers a method to simplify the production of celluloid, making industrial production possible. 1872: PVC is accidentally synthesized in 1872 by German chemist Eugen Baumann ...
Plastic film is a thin continuous polymeric material. Thicker plastic material is often called a "sheet". Thicker plastic material is often called a "sheet". These thin plastic membranes are used to separate areas or volumes, to hold items, to act as barriers, or as printable surfaces.
