Tyvek Rolls are a type of packaging material made from flash-spun high-density polyethylene fibers into a continuous sheet. The resulting material is tough, durable, and lightweight, with a paper-like texture but superior tear and puncture resistance. They are frequently used to protect fragile or valuable items such as electronics, artwork, and antiques. Tyvek rolls are used in the medical industry as a sterile barrier for medical devices and instruments, as well as for medical supply packaging. They are used in construction applications as a breathable barrier to protect buildings from moisture and air infiltration while allowing for the release of water vapor. They are very economical to use.
