There is no such thing as "archival" double sided tape!!! What idiot told you that???!
That is one of the WORST things you can do to ANY work of art!
The 3M PMA isn't "archival" either.
The ONLY adhesive that is archival is rice paste or wheat paste and Mulberry paper hinges. Archival means that the method you use has to be completly reversable, leaving no chemical residue on the paper.
So, to answer your question, no.
Seriously, if you want to be "archival" in your mounting process, do it right.
Otherwise, you can use any chemically invasive method you'd like.
Ok... rant over.
