Envelopes de envio MAILmedia Securitex DIN B4 Branco, pack de 100 – capas de envio protetoras

MAILmedia Securitex DIN B4 White mailing bags, pack of 100, are disposable protective envelopes designed to transport B4-size documents and flat items. The white exterior and secure closure provide a clean, uniform appearance for business correspondence and e-commerce shipments. These mailing bags resist moisture and surface dirt while offering a lightweight outer layer that simplifies handling and postage calculation.

Advantages

These Securitex mailing bags combine tear-resistant construction with a self-sealing adhesive strip for quick closure. The slim profile reduces bulk and postage cost compared with boxed packaging, while the white finish supports a professional look and allows for easy labeling or direct printing. Being lightweight and disposable, they streamline packing processes in busy office and fulfillment environments.

Suitable for

• Sending documents in B4 format (folded or flat)
• E-commerce shipments of flat products (paperbacks, brochures, prints)
• Business and administrative mailings, invoices and contracts
• Internal transfers and archive dispatches where basic protection is required

Key specifications

• Format: fits B4 documents and similarly sized flat items
• Quantity: pack of 100 mailing bags
• Color: white exterior for clear addressing and labeling
• Closure: self-adhesive strip for secure and fast sealing
• Material properties: lightweight, moisture-resistant outer layer with tear resistance for surface protection
• Design: slim envelope profile optimized for postal handling and reduced postage weight

How to use

Insert the B4 document or flat item into the mailing bag, ensuring the contents lie flat and do not overfill the envelope. Remove the protective strip from the adhesive closure and press firmly along the flap to seal. Verify the address and postage are applied to the exterior surface, and avoid folding over the sealed flap. For added protection of sensitive documents, place the item in a protective inner sleeve before sealing.

Recommendations

Store unopened packs in a dry, cool place away from direct sunlight to preserve adhesive performance. For items requiring higher protection, combine with inner cardboard stiffeners or bubble sleeves before placing in the mailing bag. Dispose of used bags according to local waste regulations.
