The folders are made from several materials: cardstock/paper (including heavyweight and laminated cardstock), polypropylene plastic, and some organizers that combine paper and plastic components.
Sheet capacity varies widely: some two-pocket folders list capacities like 50–225 sheets, plastic pockets show capacities around 75–80 sheets, expanding pockets advertise capacities up to 700 sheets, and multi-pocket expanding organizers list totals as high as 1,400 sheets.
Common uses include school and classroom work (assignments), office and home organization, presentations, keeping bills and receipts, and general everyday document storage and organization.
Cardstock weights shown include 250 GSM for some pocket portfolios and 300 GSM heavyweight matte laminated cardstock for decorative file folders.
Pocket counts range from simple 2-pocket folders up to multi-pocket organizers; documented counts in the listings include 2, 8, 12, and 19 pockets.
Folder sizes cluster near standard letter dimensions, with many listings around 11.5 x 9.5 inches; some organizers or expandable pockets are slightly larger (for example, 12.7 x 10.4 inches).
