Tyvek UV Facade

I am looking for a suitable packing for a stack of sheets of
wallpaper, on which the bright pink pattern is screen-printed. As
the colors of the wallpaper fade easily when exposed to light,
emphasis is put on the importance of a lightproof packing. During my
search for lightproof packing material, I found "black tyvek":

This is product of DuPont and a construction material. According to
the brochure, this product has

   "Exceptional moisture management properties High
    vapour-permeability for maximum 'breathability' Easy to
    install - difficult to damage Outstanding durability backed by
    rigorous performance testing Guaranteed long term performance"

A few samples of this UV Facade Tyvek (2524B) were sent to me. This
non-woven consists of two layers of tyvek adhered to each other,
that is the generally known soft tyvek (the white one that is used
for several conservation goals) and a black variant. The black tyvek
is heavier and thicker than tyvek soft (195 g/m2 to 60 g/m2), and
therefore more rigid as well.

Does anyone have experience with this black tyvek? Is this suitable
as a packing material for long-term conservation?

Rebecca
