Tyvek wristband is made of flash spun high-density polyethylene fibers. It is famous for its water-resistance and tamper-proof feature. Tyvek was first invented by Dupont in 1955 and was first used in the building industry. It was introduced for commercial purposes in 1967. And since then, it has been a usual alternative for paper, especially if the paper is not strong enough. It has a lightweight feature and is tear-resistant.
