Tyvek

This is a paper-like fibrous plastic material. Our primary use for Tyvek is the making of custom envelopes for oddly-shaped or oversize materials which are suitable for an envelope-type enclosure. Its main advantage over paper for this application is its high resistance to tearing. Since the orientation of the fibers is random, it has no grain direction, unlike most of the various types of papers, cloths, and boards we use. Consequently, the use of scraps is optimized.
