Tyvek is a brand of synthetic flashspun high-density polyethylene fibers. It is a nonwoven product consisting of spun bond olefin fiber. Tyveks properties, such as being difficult to tear but easily cut, and waterproof against liquids while allowing water vapor to penetrate, have led to it being used in a variety of applications. Some of the common uses of Tyvek include:

• Housewrap: Tyvek is often used as housewrap, a synthetic material used to protect buildings during construction.

• Personal Protective Equipment (PPE): Tyvek is used to make protective clothing, such as laboratory coats, aprons, and coveralls with hoods and booties.

• Medical Packaging: DuPont released Tyvek packaging for sterile instruments that were to be used by surgeons and doctors in the medical field.

• Printing substrate: Tyvek is a remarkably tough printing substrate that is ideal for applications where durability and tear resistance is of prime importance.

• Consumer products: Tyvek provides endless possibilities for both traditional and retail-focused specialty products, such as apparel, accessories, home décor, and electronics.

Tyvek is lightweight, durable, and breathable, yet resistant to water, abrasion, bacterial penetration, and aging. It is completely waterproof and keeps all of its strength when wet. Tyvek is also easy to sterilize and once made into packaging is able to maintain sterile for many years.
