plastic poly folders

Most folders are made from polypropylene (a common poly plastic). A few listings note metal components where folders include metal prongs.

Folders are sold as single-folder packages and as multi-packs. Examples in the listings include single-folder options and 10‑count packs.

Review summaries commonly describe the folders as sturdy, with many users reporting they last through a school year. Durability and long-lasting use are frequent comments.

Many folders are sized for letter paper (8.5" x 11") and several are 3‑hole punched so they can be stored in standard three‑ring binders.

Listed dimensions include several flat-folder sizes and one expanding file. Examples given are: 9.39 in (L) x 11.73 in (W); 11.6 in (L) x 9.3 in (W); 11.34 in (L) x 9.37 in (W); 11.75 in (L) x 9.5 in (W). One expanding file is listed as 10.38 in (H) x 13.38 in (W) x 1.5 in (D).

The listings show sheet capacities of about 12 sheets, 25 sheets, and 50 sheets across different folder types.

Common features include internal pockets (often two), 3‑hole punch compatibility for binders, and some folders with metal prongs to secure pages. Hanging file folders include hooks, and a few items feature a clear cover or a clear front pocket.

Some organizers include zipper closures with reinforced gussets and expandable compartments (one expanding file lists seven compartments). Other folders offer a clear front pocket or clear cover for display or scanning.

Some listings state a one‑year guarantee or a "1 Year Limited Warranty," typically excluding misuse. One listing notes a phone number is available to request a copy of the warranty.
