MAILmedia bolsas de papel com fundo B4, 110 g/m², castanho natural, 52 g

Paper back wall pockets MAILmedia in B4 format are made from 110 g/m² natural brown natron paper and weigh 52 g each. Designed to be attached to parcels and mailing packages, these pockets provide a visible and protected place for invoices, packing lists, return labels and other shipping documents. The paper surface offers good adhesion for labels and printing, while the transparent glue strip backing ensures secure fixation to cardboard, paper and many packaging surfaces.

Advantages

These B4 paper back wall pockets combine lightweight construction with durable 110 g/m² natron paper that resists tearing during handling. The natural brown colour blends with standard shipping cartons and reduces the visibility of dirt. Pre-applied adhesive backing speeds up application and reduces handling time when preparing shipments. The size accommodates larger documents without folding and keeps paperwork flat and legible.

Suitable for

• Attaching invoices and packing lists to parcel cartons
• Securing return labels on outgoing shipments
• Warehouse picking and dispatch documentation
• Mailroom and postal handling where visible paperwork is needed

How to use

Place the required document inside the pocket so it lies flat against the paper. Remove the protective strip from the adhesive backing and press the pocket firmly onto the clean, dry surface of the parcel or mail item, smoothing from the centre outward to avoid air pockets. Ensure the pocket is positioned where documents are easily visible and accessible for carriers or recipients. For best adhesion, apply at room temperature onto cardboard, paper or similar packaging materials and allow a few seconds of pressure to secure the bond.

Recommendations

Store the pockets flat in a dry environment away from direct sunlight. Avoid applying to wet or heavily dusted surfaces. For shipments exposed to moisture, combine the paper pocket with a transparent protective sleeve or place documents in a small plastic bag before inserting them to increase protection.
