Tyvek® Envelopes are made of DuPont™ Tyvek® brand protective material, not paper. They’re water-, puncture- and rip-resistant and virtually indestructible.
They’re also ultra-light. So you can save on postage by using them in place of heavier envelopes and boxes!
And they can be custom-designed to fit your exact requirements.
Plus Tyvek® Envelopes have a distinctive look and feel that set them apart from other mail – making them more likely to be opened first.
Let us help you select—or design—an exceptionally strong, lightweight Tyvek® Envelope that’s right for you.
