Tyvek
Tyvek is a special material made by DuPont that's widely used in packaging, especially for medical and industrial products. It's like a super-strong paper that's actually made from plastic fibers. People in packaging jobs work with Tyvek because it's waterproof, very hard to tear, and provides an excellent barrier against bacteria while still being breathable. It's similar to other medical-grade packaging materials but is particularly valued because it can be sterilized and still maintain its protective properties. When you see this term in job descriptions, it usually means the role involves working with medical packaging, protective packaging, or sterile barrier systems.
