On the other hand, I know from my incoming mail that a significant number
of firms use Tyvek routinely as their 9x12 envelop, even for material that
could be mailed without risk in kraft envelops. This, obviously, is
overkill.
But, for uses such as John propounds where greater strength is needed,
Tyvek may make sense. One further matter to consider is that a major
reclaimer, EnviroPlastic is recycling used milk jugs into Tyvek.
Unless there's some other material for heavy duty envelop use that has a
smaller environmental footprint, Tom's criteria seems to make sense.
