Document sleeve horizontal A3 transparent 120 µm Donau DONA0584, pack of 50

Transparent horizontal document sleeves in A3 format from Donau, made of 120 µm polypropylene. These sleeves are open on the short side to allow easy insertion and removal of A3 sheets, drawings, posters and prints while protecting them from dirt, moisture and wear. Supplied in a pack of 50, they are suitable for everyday office use, archiving and presentation purposes where A3-format protection and clear visibility are required.

Advantages

The short-side opening simplifies handling and reduces the risk of edge damage during insertion. Being transparent and sized for A3 sheets, the sleeves keep originals visible and accessible without the need for removal. The pack quantity ensures consistent supply for routine filing, displays and project work.

How to use

Insert documents by sliding the A3 sheet into the sleeve through the short-side opening, aligning edges to avoid folding or creasing. For best protection, ensure the document is dry and free of loose particles before insertion. Use the sleeves in ring binders, archival boxes or on display boards as needed; when stacking sleeve-filled documents, align them evenly to prevent edge stress. Replace any sleeve that shows signs of damage to maintain protection.

Usage recommendations

Store sleeves flat in a cool, dry place away from direct sunlight to prevent warping. For long-term archiving of sensitive originals, pair the sleeves with buffered or archival-quality backing boards. Avoid contact with solvents or inks that may transfer through low-absorbency materials.
