The Q-Connect DL Window Self-Seal Envelopes (KF3481) are designed for office administrators and home-based professionals who require a high-volume, efficient solution for standardized business correspondence. These envelopes provide the significant benefit of a self-seal closure, which saves time during large mail-outs by removing the need for moisture or adhesive tape; however, they are intended for light-to-medium weight documents, as their 90gsm paper construction may be too thin for shipping thick catalogs or multiple booklets.

A DL envelope measures 110 x 220mm, which is designed to hold an A4 sheet of paper folded into thirds.
No, these are self-seal envelopes featuring a pressure-sensitive adhesive strip that requires no water.
These envelopes are made from 90gsm paper, which is the standard weight for most office and mailing envelopes.
While the paper is suitable for standard printing, it is recommended to print your address labels or letters before inserting them into the envelope to avoid damage to the printer mechanism.
Each pack contains 1000 envelopes.
The address window measures 35 x 89mm, positioned 19mm from the left edge and 18mm from the bottom.
Ensure the adhesive strip is free of paper dust or debris, and apply firm, even pressure along the entire length of the flap.
Verify that your letter is folded tightly to A4 thirds and that the address block on your document matches the window coordinates of 35 x 89mm.
Gently fan the stack to separate them. If the adhesive has been damaged by humidity, the affected envelopes may need to be discarded.
For optimal results, ensure your document address block is positioned approximately 19mm from the left edge and 18mm from the bottom edge of the sheet to align with the window. When storing these envelopes, keep them in a cool, dry environment. Avoid high heat or high humidity, as these conditions can prematurely activate the self-seal adhesive or cause the paper to ripple, which may result in envelopes sticking together in the box.
