Description Envelopes expand to provide lightweight, inexpensive shipping for bulky items. Expandable envelopes are made of puncture, tear and moisture-resistant DuPont Tyvek material. Envelopes made with Tyvek are half the weight of heavy duty paper envelopes, so you save on postage with each mailing.
