Pocket Tyvek Envelopes
Unsurpassed protection of your important or confidential documents
Try fighting your way out of this Tyvek envelope! Our super tough synthetic envelopes are perfect for heavy duty and irregular items e.g. folders, manuals, textiles and spare parts. These lightweight Tyvek envelopes feature a high tear resistance and a self seal strip.
The Tyvek envelopes protective material is NOT paper but a brand of flashspun high-density polyethylene fibers. The nondirectional fibers (plexifilaments) are spun first and then bonded together using heat and pressure. This creates the unique Tyvek envelope property of water vapor passing through the envelope to be breathable, while still keeping out liquid water.
