I would suggest avoiding propriety named products that are composed
of unknown materials and manufacture. Choosing a material for
backing purposes depends mostly on whether the user needs to provide
a sealed (moisture and air) microenvironment for a specific
collection of paintings. The most sealing materials include glass
and metals (a thin aluminum foil adhered to an acid-free cardboard
would be appropriate for weight considerations). Otherwise, one
might consider non-woven polyester canvas should there be the need
to apply a non-sealing backing material.
