Expansion Envelopes

Expansion envelopes are designed to accommodate bulky or thick items that standard envelopes cannot contain. These versatile envelopes feature accordion-style sides that expand to provide extra space, making them ideal for mailing documents, catalogs, booklets and other bulky materials. At Elite Envelope, we understand the importance of having the right envelope for your specific needs. With our extensive range of expansion envelopes, you can trust us to provide the perfect solution for your mailing requirements.

Also known as gusset envelopes or expandable gusset envelopes, these durable and versatile envelopes are generally made in heavy paper up to 40# as well as Tyvek and Herculink.

Many sizes and styles of Tyvek expandable envelopes are available as stock items. However all custom gusset envelope sizes are available including with windows and window patches.

Whether you’re seeking printed gusset envelopes or unprinted, we can help put together just the right envelope for your particular application.  

Great for small web-based companies who are sending out products that have some heft.

Also great for thick packets of documents, samples, prints and much more.

Measuring expansion envelopes can be a little tricky! We wrote a blog post about how to measure several types of envelopes.
