A slider bag, slider storage bag, zipper bag, or zippie is an inexpensive flexible rectangular storage bag, usually mainly transparent, made of polyethylene or similar plastic, which can be sealed and opened many times by a slider which works in a similar way to a zip fastener.
Many such slider bags are used to contain foodstuffs, such as sandwiches and freezer storage. Single and multiple small items for sale are often packed in small slider bags for convenience and visibility.
Several types of reclosable features are available for plastic slider bags. Sometimes other types of bag, such as a cloth bag for toiletries fitted with a conventional zip fastener, are described as slider bags.
