Polythene[Poly+ ethene]:
-------------------------------------
--->Polythene is a plastic obtained by the polymerisation of a chemical compound known as Ethene.
---->Polythene is used in making polythene bags,water proof plastic sheets, bottles etc.
Advantages over natural Fibre:
**************************************
1. Polythene is tough.
2. It is durable.
3. Quite light Weight.
4. Chemically unreactive.
5. Poor conductors of heat and electricity.
6.Can be moulded in different shapes.
7. Quite cheap.

Nowadays, there 'Natural' has become a buzz word used by companies and marketers to show how their product is 'natural' and hence better. However, there are many synthetic things/materials/products which actually provide far more advantages than natural alternatives.
Polythene is once such martial was first made in Germany but Industrial product began in England in 1933. It is the most basic form of plastic and over 80 million tonnes of it is produced every years, usually for packaging.
Some advantages for natural materials include:
1. Polythene can be moudled into different forms so it can be hard and still retain it's transparent look
2. No other naturally occurring product can be used to make such a wide variety of products, from toy covers, gift wrappers to large industrial water and drainage pipes. It's versatility is it's biggest advantage.
3. It takes years before Polythene can degrade. Which means it has stood the test of time as a robust material which is resistant to water, moisture, Rust and provides amazing durability
