Tyvek - Wikipedia, the free encyclopedia

Tyvek (pronounced /taɪˈvɛk/) is a brand of flashspun high-density polyethylene fibers, a synthetic material; the name is a registered trademark of DuPont.

Water vapor can pass through Tyvek (highly breathable), but not liquid water, so the material lends itself to a variety of applications: medical packaging, envelopes, car covers, air and water intrusion barriers (housewrap) under house siding, labels, wristbands, mycology, and graphics. Tyvek is sometimes erroneously referred to as "Tyvex."
