Sobre MAILmedia DIN largo autoadhesivo con ventana 225430 – formato DIN largo, autoadhesivo, ventana transparente

MAILmedia Envelope model 225430 is a long DIN-format self-adhesive envelope with a transparent address window, designed for practical business use. The envelope fits standard long DIN dimensions suitable for A4 documents folded into thirds, and the clear window displays recipient details without the need for separate labels. The peel-and-seal closure enables quick and secure sealing, reducing preparation time for bulk mailings and routine correspondence.

Advantages

The envelope combines a long DIN format with a built-in transparent window to streamline addressing. Its self-adhesive peel-and-seal flap provides fast closure without additional tape or glue, while the robust paper construction maintains document protection during handling. The window is positioned to match standard document layouts so that recipient information is visible immediately, supporting efficient mailing workflows and a professional appearance.

• Invoices, statements and delivery notes folded to long DIN size
• Mass mailing campaigns and bulk dispatches
• Administrative offices, accounting departments and service providers

Key specifications

How to use

Insert a folded A4 document so the recipient address aligns with the transparent window.

Verify window alignment before sealing when using custom-printed forms.
