Tyvek

From Freepedia

Tyvek is a synthetic material made of high-density polyethylene fibers; the name is a registered trademark of the DuPont Company. It has a number of uses, including envelopes and siding for houses. It is very strong; nearly impossible for the average person to tear.

Tyvek has been used by the United States Postal Service for some of its Priority Mail and Express Mail packages and for banknotes in some countries.

Tyvek suits are often worn by mechanics over their clothes to avoid contact with oil and fuel. These suits can be commonly seen and recognized as they are typically one piece white jumpsuits made of Tyvek.

Tyvek superficially resembles paper; for example, it can be written and printed on. However, Tyvek envelopes may not be recycled as used paper. Instead, DuPont runs a recycling program in the United States.

Tyvek is manufactured in Richmond, Virginia and Luxembourg.
