Working with Tyvek®

Because Tyvek® is different than paper, there are special considerations for processors to work with and enjoy the superior performance benefits of Tyvek®:

  • Spunbonded Olefin is more elastic than paper.  It should be handled under the lowest tension practical to avoid distortion and misregistration.

  • Spunbonded Olefin is tough, so when sheeting, slitting and die-cutting, each filament must be completely cut; “hangers” will not break off as they do with paper.

  • Spunbonded Olefin has lower surface friction, which may facilitate handling in some operations.

  • Spunbonded Olefin is slippery and should not be used in any application where it will be walked on without the application of a slip-resistant coating. Garments made of Spunbonded Olefin should have slip-resistant or anti-slip materials on the outer surface of boots, shoe covers or other garment surfaces in conditions where slipping could occur.

  • Although unaffected by water and many chemicals, Spunbonded Olefin may swell on contact with certain organic solvents used in some inks, coatings and adhesives. It is recommended that you conduct your own tests before use.

  • Spunbonded Olefin absorbs little or no moisture; therefore, longer drying times are required for most inks, coatings and adhesives.

  • Spunbonded Olefin is thermoplastic. It maintains its toughness and flexibility down to -100°F (-73°C)  An unrestrained sheet of Spunbonded Olefin is dimensionally stable up to 270°F (132°C) and will not shrink. Temperatures above 175°F (79°C) should be avoided when processing under tension.

  • Spunbonded Olefin can be safely incinerated. Under optimal conditions, it yields water and carbon dioxide, and leaves essentially no residue for disposal.
