Having problems printing on board envelopes?

Printing on all board envelopes has historically been a problem, but Opal Envelopes make it easy. We take the plain board stock, pre-print the sheets and then make up in to the finished envelope. This means no more ‘set off’ for you overprinters!

Type of closure on board envelopes.

We can produce either the stock or bespoke board envelope with a hot melt peel and seal strip or a tuck in flap. If you want the peel and seal option we can also add an easy opening tear strip to the flap.


You can address your mail piece by applying a label to the front of the board envelope or if you prefer we can produce the standard stock or bespoke board envelope with a window aperture (36 micron film) If you need a bespoke size/shape or position of window please call our sales office to discuss.


If your product needs an envelope with extra capacity don’t worry we have the answer, check out the video on the following page, EXPANDELOPE GUSSET ENVELOPE . The video shows an Expandelope® being produced in a paper weight material but any of the boards listed above are ok, again gives us a call to talk through your requirements.
