Envelope MAILmedia DIN long self-adhesive with window model 1 (MPN 227420)

MAILmedia DIN long self-adhesive envelope with window model 1 is a long-format mailing envelope designed to hold standard DIN long documents and invoices. The envelope features a transparent window positioned to display address or invoice details without additional labeling and uses a peel-and-seal closure for quick, hygienic sealing. Constructed for compatibility with common mailing workflows, it is suitable for both manual and automated mailing processes.

Advantages

The self-adhesive closure eliminates the need for moisture or adhesive tape, ensuring fast and reliable sealing. The transparent window reduces the need for printing or handwriting recipient details on the outer surface and helps streamline invoice and statement dispatch. The long-format design accommodates folded documents without excessive creasing and its standardized dimensions fit DIN long document requirements and many automated envelope feeders.

• Dispatch of contracts, long-format forms and brochures
• Automated mailing lines and envelope inserters

How to use

Insert folded or flat documents so that address or invoice details align with the transparent window.
