A plastic bag, poly bag, or pouch is a type of container made of thin, flexible, plastic film, nonwoven fabric, or plastic textile. Plastic bags are used for containing and transporting goods such as foods, produce, powders, ice, magazines, chemicals, and waste. It is a common form of packaging.

Why are polythene bags used?

Polythene is used for plastic bags because it has useful properties – like being water-resistant and having a low density (which means a low weight). When compared to most other plastics, LDPE wins hands down in strength to weight ratio, especially at its price point.

Advantages :

Poly bags offer many benefits for businesses and consumers alike. They are durable, lightweight, cost-effective, eco-friendly, and incredibly versatile. For these reasons, poly bags are a great choice for any packaging or shipping needs.

The bags can be made with a variety of plastics films. Polyethylene (LDPE, LLDPE, etc.) is the most common. Other forms, including laminates and co-extrusions can be used when the physical properties are needed. Plastics to create single use bags are primarily made with Fossil fuels. International Plastic Bag Free Day is celebrated on July 3.
