There are many different styles of pocket envelopes. These envelopes have their own terminology and names. There are even names for where the envelopes are made. This can help you to find the right type of envelope for every need and situation. These envelopes are not all common envelopes and some need to be special ordered, but this will be noted.
The first aspect of pocket envelopes that most be thought of is how the envelope opens. While square envelopes do not have a special name for the way that they open, rectangular envelopes do. If the envelope opens on the narrow end, then it is called a top pocket envelope. If the envelope opens on the wide end, then it is called a side pocket envelope. The side pocket envelope is easier to open and insert information within and therefore it is more often used in mass mailings than the top pocket envelope.
Next a person has to consider the flap style on the envelope. There are 4 primary different flaps that are available on pocket envelopes. The first is the point flap. This flap is the one where the flap is shaped like a sharp triangle. This is an easy flap to tuck into the pocket and provides a larger opening to insert items such as cards. This is most often seen in decorative envelopes and envelopes that are for cards. The commercial envelope is a longer version of the wallet flat. These flaps are a softer version of the pointed flap and are often not as deep as the point flap. These flaps are more square in shape than the pointed flap and have wavy details. The square flap is a rectangular version of the pointed flap. This flap allows for a large opening and a very straight closing option. This is a more formal closure.
There are dozens of sizes of pocket envelopes. These envelopes range from the smallest of invitation envelopes to the largest magazine envelopes. The averages are commercial size, invitation size, booklet and magazine sizes. These envelopes can come in further size variations between using the United State’s standard size envelopes or the rest of the world’s ISO metric envelopes. Each of these different size envelopes can have a specialized flap and other features on them as well.
Windows are very popular on pocket envelopes. The windows enable the business to save money by printing the information on the bill or advertisement rather than printing it on the envelope as well. These envelopes can come in several different styles. The envelopes can come with or without the clear plastic that could cover the window. The clear plastic does make the envelope more secure but it is not as easily recycled. The empty envelope is slightly less secure, but it does have the option of being easily recycled. The envelope can also have multiple windows allowing for the return information or marketing deal to be visible as well. There are no standards as to the placement of the windows on pocket envelopes.
Lining is very important when discussing pocket envelopes. Most envelopes are made with a lighter weight paper. This makes it possible to see what is printed on the paper within the envelope. A thicker paper can be used to prevent people from snooping in the mail, however, this is not the only means available. Printing a lining onto the inside of the envelope is another spying prevention tool. Most of these liners are often simply blue lines or pebbling that works to confuse the eye and make it almost impossible to read what is in the envelope. Some envelopes have colored linings and very few have black lining.
The United States standard for shipping pocket envelopes states that the envelope should be between five inches and eleven and a half inches long. If the envelope is larger than this, additional shipping might be charged. If the envelope is smaller than this standard, it may be lost during the sorting process. Lost envelopes are looked for between batches; however, they are not always found and are frequently lost. To prevent this from occurring, please be sure that the envelope is large enough to be seen and large enough for the machines to handle.
