How to use

Fold your document to the DIN long format so the recipient address aligns with the envelope window, insert the paper fully to ensure the address is visible through the window, then peel and press the adhesive flap to seal. For automated processing, verify that fold and address placement settings on your folding machine match the window position. Store unopened packs in a dry environment to prevent moisture damage to the paper and adhesive.

Recommendations

For clear visibility through the window, print recipient addresses on the correct position of the document and avoid heavy inks or patterns that may obscure legibility. When using automated inserting equipment, test a small batch to confirm alignment before processing larger volumes.
