You name it, there’s a DuPont™ Tyvek® designed to do it.
DuPont™ Tyvek® is very fine polyethylene fibers (seven times finer, in fact, than human hair) bonded by heat and pressure to create a printing substrate that isn’t paper, fabric, or film, but combines the best properties of all three.
It is produced in “hard” and “soft” structure types. Products beginning with a 10 are “hard” structure products. For instance, DuPont™ Tyvek® 1056D is a hard structure. These products are considered “hard,” as they are smooth, stiff, non-directional paper-like substrates with good printability. These products are available in various basis weights or calipers.

Tyvek® styles beginning with a 14 are “soft” structures. An example of a soft structure product is Tyvek® 1443R. These are lightly bonded products with an embossed pattern, providing a softer fabric-like flexible substrate with tear resistance. Like Type 10, they have high opacity, excellent whiteness and good surface stability. Sewing, gluing, and, to a limited extent, ultrasonic seaming and heat sealing may be used in fabricating materials using these styles. These styles can be printed, but are more demanding than hard structures.

| DuPont™ Tyvek® is extremely popular for tags and labels. It makes them stronger so they last longer, easier to see, more comfortable to wear and better able to stand up to the elements. |
Soft structure styles beginning with a 14, or Type 14, are used where barrier, durability and breathability are required. They offer excellent splash and dry protection against particulate matter and provide an excellent bacterial barrier. The unique low-linting properties, combined with the barrier properties, make Type 14 an excellent material for cleanroom apparel in pharmaceutical manufacture and electronic device assembly.
CORONA AND ANTISTATIC TREATMENTS IMPROVE ADHESION, PRINTABILITY AND HANDLING
Tyvek® products used in printing are corona treated to improve ink and coating adhesion. This electronic charging of the sheet oxidizes the surface and increases the wettability to inks, coatings and adhesives. Unlike other products, which require additional corona treatments, our treatment lasts more than 20 years.
To reduce the buildup of static electricity during sheet and roll handling operations, some styles are coated with a proprietary antistatic agent. Tyvek® used in sterile medical device packaging and in direct food contact applications are neither corona nor antistatic treated. These products end in the letter B, such as Tyvek® 1059B.
