Document sleeves Donau DONAU A4 polypropylene 50 µm, grooved texture, 100 pcs

Donau A4 document sleeves are transparent protective pockets made from polypropylene with a 50 µm thickness, supplied in a pack of 100. They are designed to protect A4-format papers from dirt, moisture and mechanical wear while maintaining full document readability. The grooved textured surface improves grip and reduces slipping when handling or inserting pages, making these sleeves suitable for filing, presentations and medium-term archiving.

Advantages

These polypropylene sleeves combine thin but durable material with a grooved texture that reduces movement between sheets and offers a non-slip surface for easier handling. The transparent finish preserves document visibility and printed colours while protecting against dust and light moisture. Supplied in a 100-piece pack, they are convenient for bulk document preparation and consistent protection across multiple files.

How to use

Insert A4 documents into the open edge of the sleeve so that the printed side remains visible through the transparent polypropylene. For best results, align the paper with the sleeve opening and slide it in slowly to avoid creases. Use the grooved surface to grip the sleeve when placing it into folders or binders; avoid folding or overstretching the pocket to maintain its integrity. When storing multiple sleeves, stack them flat to prevent bending of the contained documents.

Usage recommendations

For long-term preservation, combine these sleeves with labelled folders and store in a dry, temperature-stable environment away from direct sunlight. Do not expose polypropylene sleeves to prolonged heat sources or sharp objects. For presentation purposes, use one sleeve per handout to keep materials clean and easy to distribute.
