Greetings: I have a question for people who are more up on new archival packing materials than I am. We've gotten several shipping crates lately from other museums (whom I would expect would use only archival-quality foams) that are filled with a soft, spongy, black foam that doesn't look like any foam I've ever been taught is safe to use. I'm just wondering if there's been a new type of foam that's ok to use with artifacts, or could it just be a coincidence that these museums have the same non-archival foam lying about that they used in these crates? Also, while I've got your ears (eyes?), does anyone have an opinion on using foam peanuts as filler in a packing crate when lightweight artifacts are wrapped or boxed in an acid-free container inside the crate? Just curious. Christine Mouw Assistant Curator Herbert Hoover Presidential Library-Museum West Branch, Iowa 52358 [log in to unmask]
