Envelope folder Donau with snap fastener, PP 180 µm, DL size, blue

Donau envelope folder with snap fastener is a slim, reusable document holder made from 180 µm polypropylene (PP). Designed to fit DL-size documents, the folder secures loose papers with a metal snap and offers protection from dust and light moisture. Its lightweight, wipe-clean surface and translucent blue finish allow quick content identification while keeping receipts, contracts and letters organised for everyday office use or for mailing.

Advantages

The 180 µm polypropylene construction provides a durable yet flexible cover that resists creasing and tearing in regular use. The metal snap fastener keeps contents securely closed during handling and transport. The translucent blue material makes it easy to identify stored documents without opening the folder, while the smooth surface is simple to clean and maintain. Reusable design supports repeated filing and mailing tasks with consistent performance.

How to use

Place DL documents or folded A4 sheets into the pocket of the envelope folder, align them so edges are flush, then close the flap and fasten the metal snap.

Clean the folder with a damp cloth when necessary and allow it to dry before storing documents inside.

Usage recommendations

Use the folder for short- to medium-term storage and transport of paper documents; avoid prolonged exposure to direct sunlight or heat sources to prevent material deformation. For heavy or bulky stacks of paper, consider a larger or stiffened folder to maintain document protection and snap integrity.
