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.
