Biurfol SPP-00-05 A4 black polypropylene folder sleeves are a pack of 20 protective covers designed to store and protect A4 documents. Made from lightweight polypropylene, each sleeve offers a moisture-resistant barrier and a smooth surface that keeps papers flat and visible while reducing dust and light handling wear. The sleeves are open at one side for easy insertion and removal of sheets and maintain a professional appearance for reports, presentations and archived paperwork.

The polypropylene material is reusable and easy to clean, while the dark colour helps conceal minor marks and creates a uniform, professional look when used in files or binders. A pack of 20 offers a ready supply for small offices, classrooms or home documentation needs.

How to use

Insert papers into the sleeve by sliding them through the open side until they lie flat against the inner surface. For multiple-page documents, ensure pages are stacked evenly before inserting to avoid wrinkling. Use the sleeves individually or place them into folders or rings as needed. Clean with a soft damp cloth to remove dust or light stains and allow to dry before storing documents again.

Usage recommendations

Store sleeves flat or upright in a dry environment away from direct sunlight to prevent distortion. Avoid exposure to high temperatures and sharp objects to maintain the integrity of the polypropylene. For long-term archival storage, pair sleeves with acid-free paper and proper storage boxes.
