Give three advantages of polythene over natural materials?

Polythene, also known as polyethylene, is a widely used synthetic polymer that has several advantages over traditional natural materials such as jute, cotton, or paper.

•  Durability and Strength: Polythene is much stronger and more durable than most natural materials. It does not tear or wear out easily, making it ideal for packaging and storage. Unlike paper or cloth bags, polythene bags can withstand moisture and pressure without losing their shape or function.
• Resistance to Water and Chemicals: One of the greatest advantages of polythene is its waterproof and chemical-resistant properties. Natural materials like cotton, jute, or paper absorb water and can weaken or decay when exposed to moisture. Polythene, on the other hand, remains unaffected by water, oils, or many chemicals, which makes it suitable for packaging food items, liquids, fertilizers, and other goods.
• Cost-Effectiveness and Versatility: Polythene is inexpensive to manufacture compared to natural alternatives and can be easily molded into different shapes, sizes, and thicknesses. Its versatility allows it to be used in a wide range of applications, from carry bags to industrial packaging.

Thus, polythene outperforms natural materials in terms of strength, resistance, and affordability, making it a preferred choice for many industries.
