Shipping bags MAILmedia B5 self-adhesive brown 9.1 g per bag

MAILmedia B5 self-adhesive brown shipping bags weigh 9.1 g per bag and are designed to carry documents and small items in B5 format. The bags combine a lightweight construction with an integrated adhesive flap for fast sealing, providing a compact protective envelope suitable for postal and courier services as well as e-commerce dispatches. The neutral brown exterior reduces visible wear and provides a simple professional appearance for routine shipments.

Advantages

The self-adhesive closure enables quick and secure sealing without additional tape or glue. At 9.1 g per bag the mailers keep parcel weight and postage costs low while still offering sufficient protection for paper, small printed materials and thin items. The B5 size is tailored for standard B5 documents, small catalogs and thin product samples, and the brown outer surface resists scuffs and minor dirt during handling.

Suitable for

• Mailing B5 documents, letters and booklets
• E-commerce shipments of small, non-fragile items
• Courier deliveries where a lightweight envelope is required
• Sending product samples, brochures and promotional materials

Key specifications

• Format: B5-compatible internal dimensions for documents and thin items
• Weight per bag: 9.1 g for reduced shipping cost impact
• Color: brown exterior
• Closure: integrated self-adhesive flap for one-step sealing
• Material properties: lightweight, tear-resistant paper-based mailer construction

How to use

Place the B5 document or item flat inside the bag, align contents so edges do not interfere with the adhesive area, then remove the protective strip and press the adhesive flap firmly along the bag edge to seal. For thicker contents ensure the item sits evenly and the flap is fully closed; if additional protection is needed, use internal padding or wrap the item before inserting it into the mailer. Address and postage labels can be applied directly to the exterior surface.

Usage recommendations

For reliable delivery, avoid overfilling beyond the bag's capacity and keep the adhesive area clean and dry before sealing. When sending heavier or sharp-edged objects, add protective inner wrapping to prevent punctures and consider a different packaging type if structural protection is required.
