Plastic document folder Biurfol OF-37 A4 hard U-type 25 pcs

Biurfol OF-37 A4 hard U-type folder set includes 25 rigid plastic folders designed to store and protect A4 papers with a U-shaped opening. Each folder is made from durable rigid plastic that holds loose sheets securely, supports easy insertion and removal of documents through the open top, and keeps papers flat during filing and transport. The set is intended for repeated use in office, school and home environments where simple, reliable protection and organization of A4 documents is required.

Advantages

The rigid construction prevents bending and creasing of stored sheets while offering light-weight handling. The U-type open side allows fast access to documents without needing additional closures, and the uniform A4 format simplifies stacking and filing. A set of 25 provides multiple folders for categorizing paperwork or sharing across teams and projects.

Suitable for

• Organizing and protecting A4 reports, contracts and forms
• School notebooks, assignments and study materials
• Presentations, handouts and meeting documents
• Archiving and short-term storage of printed materials
• Transporting documents between office locations

Key specifications

How to use

Insert A4 sheets into each folder by sliding them through the U-shaped opening until they lie flat against the back. For best results, align paper edges before insertion to avoid folding. Use folders individually to separate document categories, or stack several folders together for transport or filing. Clean with a soft cloth and mild detergent if needed; avoid abrasive materials and excessive heat.

Usage recommendations

Store folders flat or upright in cabinets to prevent warping. Do not overload a single folder with excessive sheets — distribute pages across several folders to maintain shape and ease of access. For long-term archiving, combine these folders with labeled outer storage boxes or binders to maintain order and protection.
