How many colors can be put on an EnvyPak?

We can print a total of 7 colors, which can be divided up according to your needs and specifications. White back-ups and coatings are also available.

Can PMS, metallic, and fluorescent inks be used?

Yes, any color ink can be used, from straight PMS (Pantone Matching System) colors to custom matches.

Can EnvyPaks be made in custom shapes?

Yes. We have the tooling and expertise to create envelopes in a variety of shapes and sizes.

What are the largest/smallest sizes EnvyPaks can be made in?

The largest EnvyPak that we can currently make is 22 x 15 inches (with a flap) and the smallest is 2 x 3 inches. These dimensions may vary based on specific applications.

What is the thickness range of material that an EnvyPak can be made with?

Ultimately, this depends on the application, but EnvyPaks have been made from materials ranging in thickness from 2.0 mm to 6.0 mm.

What materials can an EnvyPak envelope be made from?

Again, it depends on the application. Typically, a mailer is made from PP or bio-PP but that material can also be a white/clear combination. An EnvyPak can also be a paper/clear combination as well (we use a specially formulated paper for our process). Other specialty pieces such as bind-ins can use SBS board, PLA and PET as well as PP.

What is the price difference between paper envelopes and EnvyPak poly envelopes?

You can expect to pay more for a poly envelope, but the comparison isn't 1:1. The application, the impression and the response rate give the EnvyPak an increased added value.

What is the difference in postage between paper and poly envelopes?

The exact postage is dependent on the method of mailing, as well as the contents. We encourage our customers to contact their local post office for specific rates.
