The Science of DuPont™ Tyvek®
DuPont™ Tyvek® brand protective material is a miracle of science
from DuPont. It is a family of tough durable sheet products of
high-density polyethylene fibers. The sheet is formed first by
spinning continuous strands of very fine interconnected fibers, and
then bonding them together with heat and pressure.
Tyvek® is white, non-toxic, chemically inert and contains no binders. The non-woven sheet, after bonding, combines a good printing or coating surface, high opacity and toughness to a degree unique among sheet products of similar weight and price.
Tyvek® is produced in two different types, namely 10 and 14. The fibers in Type 10 Style are bonded to form a tough, dense, opaque sheet. The dense packing of the fine, interconnected fibers produces a smooth surface, high opacity and whiteness. The large number of bonds per unit area results in a stable and abrasion resistant surface with a stiffness similar to paper. Fiber bonding of Type 14 is restricted to discrete points in the non-woven sheet, producing a high degree of fiber mobility, and giving the non-woven a fabric-like drape.
DuPont™ Tyvek® is a unique nonwoven material only from DuPont. Tyvek® is made of 100% high density polyethylene fibers randomly laid and compressed to form a remarkably tough printing substrate that is ideal for applications where durability & tear resistance is of prime importance. Tyvek® can resist repeated folding and flexing without tearing. It can also be glued, laminated, sewn, stapled and fixed.
Tyvek® combines the performance of paper, film and fabric and thus makes it ideal for a wide range of applications. Because of its unique physical properties, Tyvek® has already been successfully used for a wide variety of applications such as:
Tyvek® is incredibly light and flexible. It boasts a remarkable strength-to-weight ratio, so coupled with the high strength and recycleability it is therefore an ideal printing substrate for banners and signs.
DuPont™ Tyvek® is made to perform in harsh, rugged and extreme conditions. Water, chemicals, heat, cold, rough handling, long-term outdoor use? No problem! Tyvek® is tear, puncture, water, UV and chemical resistant.
Water-resistant and chemical-resistant
When wet, paper absorbs humidity and falls apart. Tyvek® repels water, keeping your message perfectly intact. Tyvek® is not affected by most acids, bases and salts. It has excellent rot and mildew resistance and resists soiling and staining.
Tyvek® can endure temperatures ranging from -70°C to +118°C. However, some deformation may occur, at around 80°C. Also, note that Tyvek® is made from high density polyethylene, which can burn; thus Tyvek® should not be considered fire resistant.
Tyvek® is printable using traditional techniques:
Tyvek® can be used for most digital printing techniques. For more information refer to our technical handbook.
DuPont™ Tyvek® is a unique and remarkably tough printing substrate incredibly easy to convert. Tyvek® can be easily:
Made of high-density polyethylene fibres (HDPE), Tyvek® is 100% recyclable just like plastic bottles.
Withstands Outdoor Exposure
There's no need for protective coating on your tags, labels or whatever—as long as you print them on DuPont™ Tyvek® substrate. Tyvek® graphics and envelopes styles can be expected to withstand outdoor exposure from one to three months, depending upon weather conditions. Special UV coatings may extend the exposure length.
The corona and antistat treatment on Tyvek® enhances the effectiveness of any ink, adhesive or other coating process and makes Tyvek® easy to use on flexographic, letterpress, offset, and some digital presses. Specifically, corona treatment on both sides of DuPont™ Tyvek® styles with a "D" suffix and style 1079 increases surface wettability, as measured by its improved surface tension (40-42 dynes/cm2).
FDA-approved for Food Contact and Sterile Applications
If you're printing tags or labels for food contact or sterile applications, we've got just what you need. Tyvek® styles 1443C and 1058C can be used for food contact applications.
