Bag

Bag packaging indicates that a specified quantity of product is packaged by the manufacturer in a bag, sealed pouch, or similar container and sold as a unit without repackaging. It is also used to describe kits/assortments where components are packaged in separate bags according to part number or parametric value, rather than in a compartmentalized box or similar rigid container.
