There can be many times when an A4 size document needs to be sent through the mail and it is not convenient to fold this. This can include when sending brochures, annual reports, pamphlets and other documents. The simplest way to send these is using 9 x 12 envelopes, which are an ideal size for an A4 document.
That standard paper size that is most commonly used for both home and business purposes is A4. This is the size used for letters, documents, catalogs, and reports. While in many cases, such as a single sheet letter, a document can easily be folded and put into a small envelope, with more bulky materials such as a reports or pamphlets,this may not be a practical thing to do.
In these cases a larger size of envelope is required and 9 x 12 envelopes are the best option for this. 9 x 12 mailing envelopes are sized just larger than a standard A4 sheet meaning that documents can be inserted without the need for folding. This can be a more professional way of sending materials and ensures that the recipient gets the contents in the best condition without creases or damage.
9 x 12 envelopes come in a number of styles depending on their use. Typically they will be either brown or white for business use although other colors are also available. The opening for inserting the mail in a 9 x 12 envelope can be along either the short or long edge and there are different types of closure methods. For a 9″ x 12″ envelope that is sent in the post this can be a moistened flap. However 12 x 9 sized envelopes are also popular for inter-office use and are typically used for sending memos and other mail around an office building. A clasp that can be easily closed and reopened is included on many to suit this purpose.
9 x 12 envelopes can therefore be useful stationary to have available and they are affordable to purchase. Staples has a wide range of 9×12 envelopes for sale available with prices being as low as around $10 for a box of 100. An example of this is the 9 x 12 White Wove Catalog Envelope which retails for $13 for a box of 100. This is white to provide a professional appearance and has a heavily gummed flap enabling it to be securely sealed when sending through the mail. Staples also sells a 9 x 12 clasp envelope made by Brown Kraft,which costs around $19 for a box of 250. This has a heavily gummed flap for use if the envelope is sent through the mail, although also includes a metal clasp to close the envelope meaning it can easily be closed and then opened for reuse.
Other companies that sell 9 x 12 envelopes include a number of Internet retailers such as Action Envelope, the Paper Mill Store and Jam Paper & Envelope. These sell envelopes 9 x 12 in a range of styles and colors at affordable prices. One point to note if you are buying 9×12 envelopes is that if you buy in bulk the cost per envelope will generally reduce and this is something to consider if you are in the market for these.
