MAILmedia Securitex Gusseted Mailing Envelope DIN C4 with Window, White, 50 mm Gusset, 25 Pieces 30004337

The MAILmedia Securitex gusseted mailing envelope combines the privacy of an opaque inner print with the convenience of a self-adhesive closure and a 50 mm expandable gusset. Unlike standard flat envelopes, it accommodates bulky items up to DIN C4 while keeping contents confidential.

Highlights

• Securitex opaque inner print protects sensitive documents from being read through the paper
• 50 mm gusset expands to hold catalogs, brochures, or small bulky items
• Self-adhesive peel-and-seal closure for quick, secure sealing without moisture
• DIN C4 format fits A4 documents unfolded
• Made from 120 g/m² kraft paper for high tear resistance

In daily use

Ideal for shipping documents, catalogs, or small goods, the envelope’s expandable sides and strong kraft paper withstand handling during transit. The address window eliminates the need for separate labels, and the white finish gives a professional appearance.
