Honestly, Tvyek is pretty miraculous. It’s permeable to water vapor but not to water, it’s nearly impossible to tear, but can be easily cut. It’s cheap and made entirely without binding chemicals. In addition to being used for wristbands, it’s used to wrap construction sites to keep out water during construction, for tear-resistant envelopes at Fed-Ex, coveralls for mechanics, and my wallet, actually.
Fun tip, though it looks like paper, Tyvek is plastic, and cannot be recycled with paper.
holy fuc
I didn’t even know it had a name
Tyvek (and other variants of it cause Tyvek is a trademark of DuPont Chem) is also used in the white hazmat suits folks wear for contamination prevention BTW
