Origin of 'polythene'
The term 'polythene' is derived from 'polyethylene', which itself comes from the Greek prefix 'poly-', meaning 'many', and the 'ethylene', derived from 'ethane', the simplest alkane hydrocarbon. Ethylene was first discovered in the 19th century, and polyethylene was first synthesized in 1898 by chemist Hermann Staudinger. However, its significant commercial production started in the 1930s. Polythene became popular after WWII due to its versatility and low cost, leading to applications in various industries including packaging, consumer products, and construction. The widespread use of polythene has raised environmental concerns, given its longevity and the difficulties associated with its disposal. As a result, there are growing efforts to promote recycling and develop biodegradable alternatives.
