MAILmedia vouwverzendenvelop B4 23410 — zelfklevend van kraftpapier (natron)

MAILmedia folding shipping bag B4 23410 is a self-adhesive kraft (natron) envelope designed to protect and ship flat items up to B4 size. The lightweight, foldable construction allows compact storage and easy handling. A peel-and-seal closure secures contents quickly without additional tape or adhesives, while the natural kraft material offers basic protection from dust and light handling during transit.

Advantages

The self-adhesive strip provides fast and secure closure, reducing packing time and eliminating the need for separate sealing materials. The fold-flat format saves storage space and simplifies logistics for businesses that ship intermittently. Kraft (natron) paper is a cost-effective option that balances durability with recyclability; it is resistant to tearing under normal mailing conditions and shows minimal stretching. The envelope’s slim profile keeps postage costs low for flat shipments.

Suitable for

• Shipping documents and letters up to B4 size
• Sending brochures, small catalogs and thin printed materials
• Mailing samples, photos or certificates that are not bulky
• Bulk storage of flat items prior to dispatch

Key specifications

• Format: fits items up to B4 size
• Material: kraft (natron) paper
• Closure: peel-and-seal self-adhesive strip
• Design: folding envelope that stores flat
• Protection level: lightweight protection from dust and light handling

How to use

Insert the flat item into the open envelope, making sure edges align with the envelope sides to avoid bending. Fold the flap over and remove the protective strip from the adhesive. Press the flap firmly to the body of the envelope along the entire length of the seal to ensure a secure closure. For added protection, consider reinforcing corners or covering printed addresses with transparent tape if required by the carrier.

Recommendations

Store envelopes flat in a dry environment to maintain adhesive performance and prevent moisture damage. Use for shipments where lightweight, low-cost protection is sufficient; avoid using for heavy, oversized, or fragile items without additional protective packaging.
