l Envelope dimensions should not vary more than + .062" (1.6 mm).
l All side flaps should be securely bonded to the bottom flap without exhibiting any curl or ripple
between the bottom flap and side seams.

o
In addition, the throat should be a maximum of .25" (6.4 mm) below the crease line at .75"
(19.05 mm) from the side edges.
l Envelope curl or twist should not exceed .25" (6.4 mm) when envelope is placed on a flat surface.
l Paper stock may range from 20 lb. (75 gsm) minimum to 28 lb. (105 gsm) maximum, but 24 lb. (90
