Document sleeves ESSELTE A3 horizontal 75 µm 10 pcs (10K139A)

ESSELTE A3 horizontal document sleeves (pack of 10) are clear matt polypropylene pockets designed to store and protect A3‑format papers, drawings and posters. Each sleeve is made from copy‑safe, acid‑free PP with recycled content and opens at the top for horizontal insertion, allowing easy access to documents while they remain in a binder or filing system. The reinforced multi‑punched strip accommodates 11 holes for use in lever arch files and can be folded to fit A4 binders when required.

Advantages

The sleeves combine a matt, embossed finish that reduces fingerprints and glare with a tear‑resistant polypropylene construction for repeated use. Their copy‑safe, acid‑free material protects documents from yellowing and degradation over time. The 11‑hole reinforced strip provides secure attachment in lever arch files and other A3/A4 systems, while the top opening permits quick insertion and removal without unlocking the binder mechanism. Made with 30% pre‑consumer PP content, the sleeves are fully recyclable.

Suitable for

• Storing and presenting A3 drawings, plans and posters
• Archiving larger documents that require copy‑safe, acid‑free storage
• Use in lever arch files and binders that accept 11‑hole punched pockets
• Temporary display or presentation materials that need a matt, non‑reflective finish
• Folding into A4 binders for mixed‑format filing

How to use

Insert documents horizontally through the open top of the sleeve so the printed side faces outward or as required for presentation. To file in a lever arch file or binder, align the reinforced 11‑hole strip with the binder rings and close the mechanism; for A4 binders, fold the pocket along the reinforced strip and then place it in the binder. Remove documents by sliding them upward out of the top opening; no need to unlock the binder mechanism when accessing contents if the sleeve remains in place.

Usage recommendations

Store sleeves in a cool, dry place away from direct sunlight to maintain material properties. For long‑term archiving, ensure contents are dry and free from adhesives or acidic materials. Clean the matt surface with a soft, dry cloth; avoid solvent‑based cleaners. Recycle the sleeves according to local polypropylene recycling guidelines when they reach end of life.
