ABSTRACT:
An envelope assembly including first and second plies 10, 70 respectively defining a front and back of an envelope along with an intermediate insert ply 40 having a message section 50 and an attachment section 52 with the message section 50 being connected by a small frangible tie 56 to the attaching section 52. A U-shaped glue line 84 secures the first and second plies 10, 70 together and one of the plies 10, 70 is provided with a tab 22 firmly secured to the attaching section 52. The ties 56 provide registration during manufacture and subsequent printing and yet are easily ruptured when the tab 22 is stripped from the form, taking the attachment section 52 with it to thereby free the message section 50 for ready removal from the envelope.
