Doug,
In a former life as a Product Safety Engineer I worked with my local label manufacturer and developed some label designs that were for all practical purposed bullet proof. These were for labels with the ANSI (now Harmonized) Danger, Warning, Caution, Notice and Safety Instructions for external product labeling typically used in a semiconductor fab.
I believe since that time new products may have been developed. I'd be happy to get you the materials and method of construction information. The caveat being knowing the exact products, processes or chemicals to which the labels might be exposed.

I wasn't just thinking of labels coming off. I include labels where the
ink or bar code washes off.
