Tyvek® can be printed using all conventional printing methods, Offset, letterpress, Flexo, Screen and Gravure and some digital printers., HP Inidgo, HP Latex, UV-inkjet, crystal point, thermal transfer (without coating).
It’s recommended to use inks for synthetic material (see Chapter 2.4 in our Technical Handbook)
Conventional inks may take 24 hours to completely dry (full coverage printing). Light ink coverage will reduce drying time drastically.
No, the fusion temperature is far above melting point of Tyvek® of 135°C.
Yes, all major self-adhesive coaters have Tyvek® in their range. A list of partners is available on our website.
All Tyvek® grades except 1442R and 1473R are certified on HP/Indigo industrial presses, certificates are available on the HP and DuPont websites. Tyvek® can also be printed on Crytal point OCE colorwave and UV-inkjet.

Surface tension of Tyvek® is between 35 and 50 dyne. The surface tension of Tyvek® lasts for several years without decreasing.
Hard structure Tyvek® can be washed, soft structure Tyvek® only 3-4 times.
Tyvek® can be dry-cleaned; however, the critical part will be the ink.
