Ralph Wiley was a college student
who worked in a laboratory at Dow Chemicals. In
1933 he came across a deposit which was very
difficult to remove from laboratory glassware. He
called it 'Eonite' - after the name of an
indestructible material in the comic strip,
Little Orphan Annie.
It was introduced by Dow Chemicals under the tradename 'Saran' and after its initial use as an anti-corrosion
coating it became famous as 'Cling Film' when
introduced as a food wrap in 1953.
