Mailing bag MAILmedia C5 White self-adhesive 90 g/m², no window

MAILmedia C5 White self-adhesive 90 g/m² mailing bag without window is a lightweight paper envelope sized for C5 documents and small items. Made from 90 g/m² white paper, the envelope features a peel-and-seal adhesive strip that provides quick and secure closure without additional tape. Its no-window design ensures a uniform exterior suitable for printing or writing recipient details directly on the surface, and the C5 format accommodates folded A4 documents, brochures, cards and similar items.

Advantages

The envelope combines a standard C5 format with durable 90 g/m² paper to give a balance of protection and low postage weight. The self-adhesive flap speeds up packing operations while reducing the need for extra sealing materials. The plain white surface is suitable for direct labeling, address printing and applying postage labels, offering a neat appearance for business correspondence and e-commerce shipments.

• Mailing folded A4 documents, invoices and letters

• E-commerce shipments of flat, lightweight items such as cards, photos or textiles folded to C5

How to use

Insert the documents or small item folded to C5 size into the envelope, remove the protective strip from the adhesive flap and press firmly along the seal to close.

Store unused envelopes flat in a dry place to preserve the paper quality and adhesive performance.

Recommendations

For machine or high-volume labeling, check compatibility with your label printer before printing. Avoid overfilling beyond the C5 capacity to prevent damage to contents and ensure reliable adhesion of the flap. When sending irregularly shaped or heavy items, use a padded or reinforced packaging alternative.
