poly pocket folders

Most poly pocket folders are made from polypropylene (a durable plastic). Some folders use paper or cardstock, and many include metal components such as prongs or brads for fastening.

Configurations range from simple two-pocket designs to multi-pocket organizers. Common multi-pocket formats include 7-, 8-, and 13-pocket layouts for more detailed sorting.

Capacities vary: two-pocket folders often hold about 25–80 sheets, multi-pocket organizers typically accommodate 130–200 sheets total, and some expanding file pockets can hold up to roughly 700 sheets.

Most poly pocket folders are designed for standard letter-size paper (8.5" x 11").

Common options include pronged fasteners, non-pronged (simple pocket) designs, 3-hole punched versions for binder use, and some organizers that use zipper closures.

Many folders include writable labels, clear front or back pockets for cover sheets or name tags, and slots for business cards or small labels for easy identification.

Expanding or gusseted pockets are described as Mylar‑reinforced and able to expand (examples up to about 3.5 inches). They often include extended top tabs for labeling and can hold large quantities of letter‑size documents.
