What Envelope Styles Are Available?

There are many different types of mailing envelopes available today with unique designs intended for a variety of purposes. Buy envelopes that are large, small, self-sealing, clasped, neutral, colorful and more for all your needs and preferences.

Business envelopes are your standard, professional envelopes. They come in classic letter envelope size as well as in a larger 10 x 15 size for documents you don’t want to fold. You can also find these with a range of sealing options.
Window envelopes have clear windows made to partially display inside contents, normally revealing the return and recipient addresses. These are ideal for mailing bills and invoices.
Security envelopes are made with extra security precautions, security-tinting, that protects the documents inside from being read by the wrong people. Security envelopes are commonly used by medical, financial and legal institutions.
Catalog envelopes are large envelopes that can fit catalogs and other thick documents. Use them for hefty reports, assignments, contracts and more.
Invitation envelopes are for sending cards and invitations. These envelopes are often more attractive and have more personality than standard business envelopes.

What Envelope Closures Are Available?

Envelopes come in a few different closure styles. All styles work well, so the type you choose is simply a matter of preference.

Gummed business envelopes have a standard glue seal that can be moistened to close. Many use saliva to moisten the seal, but if you ship frequently, you may want to invest in a sponge to make this process easier.
Self-seal business envelopes are incredibly easy to use. These are also called peel-and-seal envelopes, because all you have to do is peel away the paper backing and press the adhesive flap to the envelope. No moisture is needed to seal this variety.
Clasp business envelopes are ideal for those who want extra security when shipping or storing important documents or other items. In addition to an adhesive strip, these also come with a metal, butterfly-style clasp to further seal the envelope.
