Buste da spedizione autoadesive MAILmedia B4 marroni 23,2 g – buste imbottite per documenti

MAILmedia B4 Brown 23.2 g self-adhesive mailing bags are brown padded postal envelopes designed to carry and protect B4-format documents and other flat items during shipment. Each envelope is lightweight at 23.2 g and includes an integrated self-seal strip for quick, tool-free closure. The padded interior helps reduce bending and minor impact damage while keeping handling simple for e‑commerce orders, office mailings and archival transfers.

Advantages

The self-adhesive closure enables fast and secure sealing without tape or additional tools, saving time in packing workflows. The brown outer layer provides a neutral, professional appearance while the padded inner layer adds a measure of protection against bending and abrasion. At 23.2 g per envelope these mailing bags keep postage costs low compared with heavier packaging and are disposable for straightforward returns or one-way shipments.
