What is Tyvek?
- Jun 14, 2018 -

Tyvek is a specialty substrate (nonwoven) made from very fine high-density polyethylene fibers. 

These fibers are flashspun, then laid as a web on a moving bed before being bonded together by 

heat and pressure. The resulting sheet of material is then converted for a multitude of uses in 

envelopes and packaging, construction, protective garments, medical packaging, graphics, bags, 

wallets, tags and labels. This unique process does not require binders or additives, so Tyvek can be 

recycled after its use.
