Why use Tyvek® Mailing Envelopes?
Tyvek® envelopes are commonly used in industries that promote a professional image. Substantial postage savings can be achieved by using a Tyvek® envelope instead of a heavier paper envelope. If you have a large mailing and are just over the weight limit for the postage class when using a paper envelope, the lighter weight of Tyvek® may bring you to the lower class of postage.
