Folder with elastic Donau DONAU tc 3460279, PP A4, 480 µm, 3-flap, semi-transparent black

The Donau folder with elastic (PP A4, 480 µm, 3-flap, semi-transparent black) is designed to store and transport A4 documents with increased stiffness and reliable closure. Made from 480 µm polypropylene, the folder provides a rigid cover that protects papers from bending while the elastic fastener keeps contents secured during handling. Three internal flaps allow separation of documents into sections and the semi-transparent black finish offers partial concealment of paperwork while preserving a neat, professional appearance.

Advantages

This folder combines durable polypropylene construction with a firm thickness that reduces deformation and improves long-term use. The elastic closure prevents accidental opening and keeps documents compact during transport. Internal three-flap design enables organized separation of papers without adding bulk. The semi-transparent black material balances privacy and quick content identification, and the smooth surface resists dirt and is easy to clean.

Suitable for

• Office document storage and transport
• School assignments, worksheets and project papers
• Client dossiers and meeting materials
• Archiving documents that require separation by section
• Fieldwork where a sturdy, closed folder is needed

Key specifications

• Format: A4 capacity
• Material: polypropylene (PP)
• Material thickness: 480 µm for increased stiffness
• Closure type: elastic fastener
• Internal layout: three flaps for document separation
• Finish: semi-transparent black

How to use

Place A4 documents inside the folder and use the three internal flaps to separate sets of papers or to secure smaller inserts. Fold the elastic fastener over the front cover to close the folder and hold contents in place. For thicker stacks, arrange material evenly across the flaps to maintain shape and allow the elastic to sit securely without excessive stretching. Store flat or upright in shelves and drawers as needed.

Usage recommendations

For best results, avoid overfilling the folder beyond its designed capacity to prevent stretching of the elastic and deformation of the edges. Clean the surface with a damp cloth and mild detergent if required; avoid solvents that can damage polypropylene. Use separate folders for long-term archival storage of critical originals and reserve this folder for active documents, transport and everyday filing.
