3 hole punch plastic folder

Most 3-hole plastic folders are made of plastic—commonly polypropylene, which is frequently specified in product listings.

They are most commonly two-pocket ("2-pocket") folders, as noted repeatedly in listings.

Most listings describe the folders as 3-hole punched so they fit standard ring binders. A majority are for non-pronged binder insertion, while at least one listing includes a metal prong (pronged) fastener option.

Sheet capacity varies by listing. Common options include 50-sheet folders, with some listings offering 75- or 100-sheet capacities.

Sizes cluster around standard letter dimensions. Examples from listings include 11.5" × 9.5", 11.34" × 9.37", and 9.5" × 11.75".

Review summaries indicate the folders commonly withstand regular school use and often last through a full school year.

Descriptions emphasize protection from bending and staining; at least one listing specifically calls the durable plastic cover water-resistant.

Some folders add organizer features beyond pockets and holes, such as a clear front pocket, reinforced spine, a business-card slot, or metal prong fasteners.

Packaging ranges from single folders to multi-packs. Example quantities in listings include 1-per-pack, 12-per-pack, and bulk 100-count options.
