By maintaining and investing in our state-of-the-art facility, Continental Envelope is one of the largest envelope converting and printing experts in the Midwest. Our technology, coupled with over 80 years of experience, enables us to provide the best in custom, direct-mail envelopes to fit your project needs – on time and exactly as you’ve ordered it.

Envelope converting, the process of creating envelopes from sheets or rolls of paper by folding, die-cutting, and gluing, means we can fulfill your custom envelope needs – for mailing envelopes, business envelopes, window envelopes, or whatever your project may require. As converting and printing specialists, we understand your project needs cannot be met with a stock envelope, so we’ve tailored our processes and capabilities to provide a large variety of different envelope sizes and styles. In addition to creating the exact envelope type you require, we print exactly what you need with some of the best equipment and materials available – supplying you with the overall highest quality.

• We produce and print over 2 billion envelopes a year. And since we specialize in custom envelopes, that means no two envelope orders are the same.
• We produce all types of custom envelopes including special windows and non-standard sizes.
• We can supply specialty envelopes for you including Tyvek envelopes, expansion envelopes, bubble and foam lined envelopes and board mailers.
• Each envelope we produce is made with a focus on quality and service. Our skilled in-house pre-press and printing team will work with you to achieve outstanding results.
• We tailor our services to the unique needs of your job – providing the type of personal services you would expect from a family owned company.

Working with Letter Shops

Continental Envelope strives to make the best possible envelope for your inserters as well as for your customers.  We understand the requirements of inserting equipment; envelopes need to be flat, the gum on the side seams need to be as high as possible and windows are to be gummed as tightly as possible.  Your customers want an attractively printed piece and we have the know-how to do just that.

We would love to work on your next order – email us at or call us at 630-262-8080.
