Disposable wristbands made of the synthetic material Tyvek are known as Tyvek wristbands. They are used when crowd management, identification, or security are required at events or locations. High-density polyethylene fibres are spun and joined to form the sturdy, long-lasting, and water-resistant material known as Tyvek. The wristbands can be fastened to the wrist using an adhesive strip or tamper-evident closure, and they are frequently printed with distinctive identifying information, such as the event name or date. Tyvek wristbands are well-liked because they are inexpensive, simple to use, and challenging to transfer or take off without causing damage to the band.
