SQUARE - Provides large area for design on flap and has contemporary appearance.  May have deckle edge.  Used widely for announcements and distinctive stationery.

WALLET - Similar to square flap, but with rounded corners.  Standard flap on most booklet, catalog and specialty commercial envelopes.  Flap style enables secure closure of bulky contents.

MAILPOINT - Originally designed to enable volume mailings to run on automatic equipment, the mailpoint flap, normally found on open end (catalog) envelopes, is being replaced by the more modern wallet flap.

COMMERCIAL - Standard flap on correspondence-style envelopes for business and commercial use.  Quality commercial designs are readily printable in the corner area, seals contents without sticking to them, and works will in automatic inserting, postal and laser applications.
