Something about the history of the 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.

Rubber also made electrification possible as it was used to insulate electrical switches. The big breakthrough which is considered the birth of modern plastics came in 1907 when Leo Baekeland invented Bakelite. Bakelite is one of the first plastics that is made from synthetic components; it was made from fossil fuels.

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 came in the eigthies!
