Reply To: Yellowing of archival plastic bags and tags


Judith: Poly does breathe albeit slower than the Tyvek and allows slow migration of temperature and humidity changes.  I don’t know if I would want to trade the polyethylene for Tyvek

Susan: considered the tissue paper idea, but the problem, is money and labor which you know all of us don’t have.  We are thinking about a “basic” wash for the stone.  With these materials you just don’t know what someone might want to do with them in 50 years and if the notes get lost of what we did to them — well, I think you see where this is going.

All: So no easy solutions, but a fact of the business we are in — I think monitoring and changing the polyethylene bags is the best we can do.
