Plastic folder Donau A4 PP sleeve L-type 180 µm, crystal, green

Donau A4 PP sleeve in L-type format is a transparent protective folder made from polypropylene with a material thickness of 180 µm. The crystal finish provides clear visibility of inserted documents while the green-coloured spine or edge gives a subtle visual distinction for organizing files. The L-type opening on two adjacent sides allows quick insertion and removal of A4 sheets without folding, and the sturdy 180 µm film offers protection against dust, spills and light wear during daily handling, presentations and storage.

Advantages

The polypropylene construction combines flexibility with dimensional stability, ensuring the sleeve stays flat and resists curling. At 180 µm thickness the sleeve provides a noticeable level of rigidity while remaining lightweight. The crystal transparency keeps printed text and images readable without glare, and the coloured edge helps with visual sorting and quick identification in binders, folders or stacks. The L-type opening supports use with machines or manual insertion and reduces the need to re-shuffle documents when accessing individual sheets.

Suitable for

• Protecting and presenting A4 documents, certificates and single-sheet prints
• Office filing and paper organization in trays, folders and portfolios
• Use during meetings, presentations and conferences for handouts and sheets
• Archiving documents that require clear visibility and moderate protection

How to use

Insert an A4 sheet into the L-type sleeve by aligning the document with the open edges and sliding it gently until it rests fully inside. For multiple-sheet use, ensure the total thickness does not exceed the sleeve capacity to avoid stretching. To remove a sheet, hold the sleeve edge and slide the paper out slowly to prevent bending. When using in binders or folders, place the sleeve with the coloured edge outward for easier identification and access.

Usage recommendations

Store sleeves flat in a cool, dry place to prevent warping. Avoid prolonged exposure to direct sunlight to reduce potential discoloration. For long-term archiving, combine with acid-free paper and climate-controlled storage. For frequent handling, consider replacing sleeves periodically to maintain clarity and protection.
