On this same topic, would one need to be wary of recycled polypropylene products? I believe  that some of the normal office store polypropylene sleeves are made from recycled materials. Would this affect the archival safe qualities we attribute to the material?

Sharon:

That dotpattern website is fantastic. I finally have a way to identify  the sleeves that were purchased and used before I started working here. On some of them, the only identifiers are that recycling code.

It also makes me feel much better about using the (cheaper than mylar) pp products.
