plastic file folder

Most plastic file folders are made from polypropylene; some document holders use polyurethane.

They’re typically sized to hold standard 8 1/2" x 11" (US letter) paper.

Options range from no pockets up to two pockets, and sheet capacity varies by style—from about 12 sheets up to roughly 150 sheets.

Many listings describe folders as water‑resistant with durable plastic covers, and reviewers often report they’re sturdy enough for regular use and can last through a school year.

Many folders come in multicolor assortments or single bright colors; some listings note that color may vary with each purchase.
