A type of plastic bag that is used to hold and package several items together, often used for small publications that might otherwise be loose in a newspaper or magazine.
The newspaper included a polybag to keep the special supplements together.
Polybag → It is formed from "poly-" (from Greek "polus", meaning many) and "bag" (from Old Norse "baggi", meaning a sack or pouch). The word "polybag" refers to a bag that can hold many items or is made from multiple materials.
Think of 'many' ('poly-') items being held in a 'bag' — that's what a polybag is.
