Most sturdy 2-pocket folders are made from polypropylene plastic. Decorative or paper-style folders are made from paper or heavyweight cardstock, often specified as 300 gsm laminated paper.
Common options include prong fasteners, 3-hole punched designs for binder insertion, and non-pronged styles (which can still be used with binders if they are 3-hole punched).
Plastic construction and durable plastic covers are the primary protective features. Product listings often note that plastic folders resist water and help protect contents from spills.
Review summaries report many folders as sturdy and long-lasting, often lasting through a full school year. Some reviewers note that pockets or prongs on lower-cost options can be less rigid than premium models.
They typically have two pockets. Many models also include internal or clear front pockets, reinforced spines, and either prong fasteners or 3-hole punching to help keep letter papers organized.
Folders are sold singly and in bulk packs. Common pack sizes include single units, packs of 6, and packs of 12.
Many folders are 3-hole punched or listed as 3-hole compatible so they fit standard 3-ring binders. Other options include prong fasteners to secure punched sheets.
