Tyvek is a durable paper or plastic material produced in the United States. It is white or off-white in color, and can be folded in specialty packaging. Its properties make it an excellent choice for various applications, including its resistance to tearing, staining and moisture. One layer is a polyethylene film, while the other layer is a polyethylene mesh. These layers are bonded together in such a way that they maintain their integrity through tensile stress. This makes tyvek a great choice for event bracelets that will last the whole event and be easily disposable.
