watching ‘saving private ryan’ and when the USA army lands at Omaha beach some of the soldiers have plastic wrap on their guns.
I can’t believe this would be true but from what I can find on the internet the movie is highly accurate
u/the_howling_cow has answered this question here. The covers were made of Pliofilm, a rubber-based material manufactured by Goodyear.
Dupont manufactured a similar product that incorporated cellophane (a plastic patented in 1912), as seen in this Saturday Evening Post ad from 1943.
