Beginners Guide to Envelopes - WCP SolutionsEveryone uses envelopes on a daily basis but how much do you really know about how they are made, what features an envelope has, and how customizable they are? Today we’re diving into everything you need to know about envelopes so the next envelope order you place, you’ll have a better knowledge of the product you’re using.

Features of an Envelope

Envelopes are made up of several features including:

  • Opening – The way the envelope opens determines what its use is. Open-end envelopes versus open side envelopes serve different purposes.
  • Window – The envelope window is the area where most of the time you see the recipient’s address and it is left open in an effort to have the mailing information on the inside of the envelope instead of being written on the outside. The window can be left open or closed or you might choose not to have a window in your envelopes at all.
  • Flap – There is a variety of types of flap options to choose from on an envelope including Commercial, Side Seam, Wallet, Square, Policy, Announcement, Baronial, Booklet, Catalog, and Square. Each type of flap offers a different aesthetic as well as serving different purposes for your mailing requirements.
  • Closure – How you close each envelope also differs greatly per product. Some of the most common types of envelope closures are: Regular Gum, Ungummed, Latex Seal, Kleenstick, Peel-n-Seal, String and Button or Clasp and Tuck Closure.
  • Seam – The look of an envelope is often distinguished by what type of seam it has. Types of seams available in envelopes include: Double Side Seam, Diagonal Side Seam, Single Center Seam, and Single Side Seam.

Popular Types of Envelopes

If you’re looking for the most basic type of envelope for your uses, No. 10 “regular” envelopes are the most widely used size for both business and personal uses. These are 4 ⅛” x 9 ½” in size and can serve multiple different purposes. For a more traditional feel, Baronial envelopes are often used for traditional uses like formal announcements and invitations. They have a distinctive deep pointed flap.

If you’ll be printing on your envelopes, commercial and side seam envelope flap options are best for machine insertion while Wallet, Square, and Policy envelope flaps are not recommended for machine insertion. When ordering envelopes for your printing needs, be sure to plan to order 10%-15% more than your project will require to have extras for test printing!
