All DVD discs are two discs bonded together with an adhesive to form a
single disc, whether they are single-sided, double-sided, single-sided dual
layer, etc.
Delamination, as being discussed in this thread, refers to failure of the
adhesive that binds the two disc halves together.

Delamination should not be a problem on single-sided DVDs and I doubt that
there is serious consideration of two-sided blanks for archiving (even
DVD-RAM). Perhaps another term is intended here, but I am not aware of
"lamination" in production of single-sided recordable DVDs.
