white poly folder

Most white poly folders are made of plastic, commonly polypropylene (often labeled as "poly"). Product descriptions frequently call out poly or poly plastic construction and polypropylene as the material.

Some white poly folders include 3-hole punches or metal prongs so they can be placed in binders or used to hold loose pages. Several two-pocket folders are explicitly listed as 3-hole punched for binder use.

Many listings emphasize durable, water-resistant poly or plastic construction and specifically note tear- and scratch-resistance to protect documents from spills and everyday damage.

You’ll find both multi-packs and single-unit options. Several presentation folders and envelopes are sold as 3-per-pack, while many plastic folders and expanding files are sold individually.

Sizes vary, but long sides typically range from about 9 to 13 inches. Examples in listings include 9 x 12, 9.5 x 11.625, and envelope-style 9.75 x 13. Several items also note they fit standard 8.5 x 11 (letter) documents.

Common configurations include single-pocket envelopes, two-pocket presentation folders, and expanding (accordion-style) files with multiple compartments — one listing shows as many as 13 pockets.

Common closures include zipper (zip) closures on envelope-style cases, string-and-button closures on expanding files, and metal prongs on some folders to secure loose pages.

Accordion-style files list multiple internal pockets (one listing shows 13), expandable gussets (one listing notes expansion to about 15.35"), tear-resistant tabs (one notes 12 tabs), and often use a string-and-button closure. Listings also describe them as reinforced and water-resistant.
