I've noticed this on books, paper packaging, and clothes — anything that will absorb an odor, basically. Is this some sort of chemical treatment they use in warehouses, or... ?

    It is likely paper and cardboard thst has not gone through processes to remove smelly components. Likely some phenols or as the other commenter mentioned, butyrate. Cheap recycled paper and cardboard often has these smells, especially if it gets wet.
