Document sleeve with perforation A4 Centrum 80633 is a polypropylene protective cover 0.18 mm thick designed for storing and protecting A4 papers, reports and invoices.

The semi-rigid polypropylene material provides a balance of flexibility and durability to protect sheets from dirt, spills and creasing during daily handling.

Advantages

Edge perforation is precisely positioned for standard binder rings, enabling fast filing without additional punching. The mixed-color assortment helps organize paperwork by category, project or priority, improving workflow in office, school or home settings. The sleeves are reusable and easy to clean, offering an economical solution for document storage.

How to use

Insert single or multiple A4 sheets into the open edge of the polypropylene sleeve so the documents lie flat against the protective film. Align the sleeve perforation with the rings of your binder and close the binder to secure the sleeve. For removal, open the binder rings and slide the sleeve out carefully to avoid creasing. Clean the sleeve surface with a soft cloth if needed and allow to dry before reusing.

Usage recommendations

Store sleeves flat in a dry environment away from direct sunlight to prevent warping or discoloration. When filing heavy sets of documents, distribute weight across several sleeves rather than overfilling a single sleeve to maintain the integrity of the perforation and prevent tearing.
