Efficiency and discretion for your business mail. Soennecken envelopes in 229 x 114 mm (DIN long+) format are the ideal solution for daily mail volumes in companies, law firms, and public authorities. The integrated window saves valuable time: the recipient's address is directly readable, eliminating the need for additional labeling or addressing of the envelope.

Your advantages at a glance

• High-quality material: Made from 80 gsm strong, wood-free paper. As the paper is lignin-free, the envelopes do not yellow and retain their brilliant white permanently.

• Secure sealing technology: The gummed flap (moist-seal) ensures a firm and reliable seal after brief moistening. The elegant, triangular sealing flap emphasizes the professional character of your mailing.

• Maximum discretion: Thanks to the high opacity, the contents remain protected from curious glances – ideal for sending confidential documents and contracts.

• Versatile printing: The envelopes are suitable for InkJet printers if you wish to apply your company logo or postage mark directly.

• Optimized for inserting machines: Equipped with external side flaps, these envelopes are excellently suited for machine processing.
