Document Sleeves Donau A4, polypropylene (PP) expanded, 120 µm, crystal, pack of 25

Donau A4 Document Sleeves are crystal-clear protective covers made from expanded polypropylene (PP) with a thickness of 120 µm, supplied in a pack of 25. Designed for storing, protecting and presenting A4 papers, certificates and printed materials, these sleeves provide transparent protection while maintaining document readability and colour fidelity. Reinforced edges help resist tearing and support frequent handling, filing and insertion into binders or folders.

Advantages

The polypropylene construction offers water-resistant and tear-resistant protection while remaining lightweight and flexible. At 120 µm thickness the sleeves balance durability and low bulk, allowing documents to be stored in folders or archive boxes without excessive space consumption. Crystal transparency ensures clear visibility of text and images, and reinforced edges reduce the risk of delamination or ripping during repeated use.

How to use

Slide documents into the sleeve opening so that the top or side insertion aligns with the sleeve orientation, making sure the paper sits flat and fully inside the protective cover. For certificates or photos, centre the item to avoid edge exposure. Store sleeves vertically in folders or horizontally in archive boxes depending on available space. When inserting multiple sleeves into binders or folders, check that reinforced edges align with binder rings or folder seams to prevent abrasion.

Usage recommendations

For long-term archiving, store sleeves in a cool, dry environment away from direct sunlight to prevent gradual material deformation or fading of inserted documents. Avoid contact with solvents or sharp objects and do not exceed recommended filling capacity of folders to maintain sleeve integrity.
