OK, after searching for Luvs diapers for a long time (they are extremely hard to come by in Canada), I finally found them available as an online order from The Real Canadian Superstore. I had read recently on reviews that they still had a strong scent so I figured I would take a chance on seeing what that scent was. I am gobsmacked to have found out this is almost the exact same scent of the original Pampers from the 80's...
On smelling the outer plastic of the package the smell was instantly recognizable, faint, but clearly almost the exact same one I remember. On opening the package the smell of the diapers themselves is WAY to strong, and it misses a certain note. I think the outer plastic used to package the diapers (the box has two sealed plastic bags in it) itself imparts an important aspect that brings things a lot closer to the original scent (as diapers back then were plastic backed).
I just got these things a couple hours ago, but I am now have a few different adult diaper brands in a garbage bag with about 20 or so of these Luvs. The adult diapers all have slightly different types of plastic backing and I am curious to see how each reacts to/absorbs the scent and what the various plastics impart to it. I am going to try some other plastics/rubber/latex products as well. The fragrance added to the diapers is I believe the same one, but it is missing the addition that those plastic backed diapers imparted. If one was to take a classic Pampers diaper from the 80's and put it in a ziplock with one of these Luvs I am pretty sure within a week or two you would have a Pampers diaper that once again smelled like it had in the past.
Luv's are owned by P&G, and this current scent they have on these is effectively the same scent, or as close as they can get to it with modern allowable components. If anyone wants to get the notes of the fragrance, get them off these things. If anyone wants scent strips, I suggest just buying a package of these.
I think other than playing around now trying to fine tune the scent with the plastics and mellowing out the scent by letting these breath for a while, my search is actually done. The box I have looks exactly as below.
