Something about the history of plastic seals:
In the 18th Century, French explorer Charles-Marie de la Condamine discovered that there was a rubber tree in the Amazon forest. It was not until the 1840s that American Charles Goodyear and British born Thomas Hancock took out patents for vulcanized rubber – rubber which was treated with Sulphur to make it more durable.
More synthetic plastics followed with polystyrene in 1929, polyester in 1930, polyvinylchloride and polythene in 1933, and nylon in 1935. The plastic industry grew during the war effort when they were used in everything including military vehicles and radar insulation. Properties and uses of plastics can be changed by altering their structure just a little bit. The plastic that a milk bottle is made of can be changed from polyethylene to polypropylene (a stronger material) simply by adding one carbon to it. The material made by adding a carbon can strengthen the plastic enough to make things like the first plastic seals that was adjustable but without metal insert – that will come in the eigthies!
