A plastic bag used to collect waste on a street in Paris.
A plastic bag, polybag, 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.
Most plastic bags are heat sealed at the seams. Some are bonded with adhesives or are stitched. Many countries are introducing legislation to phase-out lightweight plastic bags.
