Flap Styles

The seal flap is the part of the envelope folded over and sealed to secure the contents. The shape of the seal flap is very important in the determination of the envelope's style and functionality.

Pointed

Elegant, traditional, and more formal. Used primarily on Baronial, greeting card and social stationery envelopes. Not recommended for laser or inserting equipment applications.

Square

Provides large area for design on flap and has contemporary appearance. May have deckle edge. The lack of a shoulder in this flap can create problems during automatic insertion. Standard No. 10 sizes are suitable for laser printing applications, while others sizes may present difficulties.

Wallet

Similar to a square flap, but with round corners. Standard flap on most booklet, catalog and specialty commercial envelopes. Flap style enables secure closure of bulky contents and is functional for automatic inserting, mailing and laser equipment processing.

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 well in automatic inserting, postal and laser applications.

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.
