ENVELOPE GLOSSARY

The following are descriptions of common standard style envelopes and commonly used terms. It is best to familiarize yourself with these terms so that you may better understand what envelopes are used and needed in a particular business. Please note, only standard stocked envelopes are listed. Almost any type of envelope imaginable can be produced.

BANGTAIL: An open side style with side seams and two flaps - a large perforated, detachable flap approximately the size and shape of the envelope that is not used for sealing and a typical seal flap of standard size used for sealing when the other flap is detached. Commonly used by financial institutions for bank-by-mail.

BANK DRIVE-UP (TELLER): Open end style with a single side seam left purposely unsealed. The seal flap is available in ungummed or latex seal. Used by financial institutions for currency transfer.

BARONIAL:   A style close to square in shape with diagonal seams and a large pointed seal flap. Common uses are greeting cards & social stationary.

BOOKLET:   A large open side style with side seams and the seal flap on the long side. Usually used for mailing booklets and multiple unfolded documents.

BUSINESS REPLY & RETURN:  Refers to the printing on the outside, the difference being who pays for return postage. Both have the address pre-printed on the face.

Most common sizes are #6¼, 6¾, 9 and remittance.
