Pliofilm

Pliofilm was a plastic wrap made by the Goodyear Tire and Rubber Company at plants in the US state of Ohio.

Production of Pliofilm was hampered during World War II because the Japanese occupation of much of Southeast Asia cut off much of the rubber supply.

The United States Public Health Service investigated the factories involved and recommended that workers wear protective sleeves made from ordinary Pliofilm.

A study of Pliofilm workers at Goodyear's Akron and St. Marys, Ohio, plants between 1936 and 1976 was used as the basis for determining the cancer slope factor and occupational exposure standards for benzene.

[17] The United States Armed Forces used Pliofilm to waterproof firearms during World War II amphibious landings.

[18] It was intended that soldiers would tear off the sleeve after landing, though some troops kept them on inland due to fields having been flooded by the Germans as a defensive measure.

[18][19][20] The Houston Chronicle series "D-Day In Color" noted that Pliofilm wrapped around weaponry is evident in an image of United States Army infantry at the Normandy landings.

[27] The American Chemical Society awarded Harold J. Osterhof the 1971 Charles Goodyear Medal for inventing Pliofilm.
