Abstract
The present invention provides an inflatable binder which has multiple air pockets which can be inflated by one or more air inlets. The binder is secured closed with a zipper or other enclosure. The material of the binder is a plastic sheet material or the like which provides for a water resistant binder. The inflated binder also provides cushioning to protect contents of the binder if dropped. In one embodiment, the front cover of the binder may have a central flat area surrounded by inflatable areas defining a frame, such that visual materials may be displayed from an inner pocket.
