plastic bag

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.

In the late 1950s, Curt Lindquist, the CEO of the Celloplast company in Sweden, experimented with a new and promising material: plastic. By cutting and heat-sealing pieces together, he invented the first seamless plastic bag. The patent was awarded in 1965. Today most plastic bags are heat sealed at the seams, while some are bonded with adhesives or are stitched.
