Rugzak voor B4-papier MAILmedia zonder venster, zelfklevend 52,3 g

MAILmedia back pocket for B4 paper is a self-adhesive document pouch designed to attach to parcels, envelopes or printed materials to keep loose sheets securely in place. This version has no transparent window and is made from a 52.3 g material that provides a lightweight but durable surface for adhesion. The back pocket is intended for use with B4-size documents such as invoices, delivery notes, packing lists and other supplementary paperwork that must travel with shipments or be added to correspondence.

Advantages

The adhesive backing enables quick application to a variety of surfaces without additional tapes or fasteners, while the no-window design protects the entire document from dirt and moisture and prevents accidental exposure of contents. Lightweight construction keeps shipping weight and costs low, and the plain back pocket offers a discreet way to include documents without altering the appearance of the outer packaging. The durable material resists tearing during handling and transit.

• Attaching invoices and packing lists to parcels
• Adding shipping labels or customs documents to packages
• Securing return forms or warranty papers with mailed items
• Enclosing contract documents or supplementary paperwork with shipments

How to use

Peel off the protective liner to expose the adhesive and press the back pocket firmly onto a clean, dry surface of the parcel or envelope, ensuring full contact at all edges to prevent lifting. Insert B4 documents into the pouch from the open end before or after application; align contents so they lie flat against the pocket. For best adhesion, avoid attaching to dusty, wet, or textured surfaces and allow a short pressure-set time before handling.

Recommendations

Store the back pockets in a cool, dry place away from direct sunlight to maintain adhesive performance. For critical or heavy shipments, consider reinforcing with an additional adhesive strip or placing the pouch on a smooth area of packaging to ensure longevity during transit.
