Reply To: Yellowing of archival plastic bags and tags


Great article.  I also have a book about caring for plastics that is very useful.  However, this thread was started not because of the inherent chemistry of plastics, but what might be causing a reaction between the plastic and objects in our collections.  In our case I really think its a matter of residual chemicals on the artifacts that are reacting to the potentially impure plastic.  I think most conservators would rather us not scrub the materials to a shine, but there may have to be some way of preventing this discoloration.

Love to hear from more people and their experiences.  It seems like this is a common problem and yet, no one has answers.
