Furthermore it contains no optical brighteners.
The average KAPPA index is < 2 (KAPPA index 5 = max. tolerance of oxidising components, see also DIN ISO 9706). 3 sides closed, only pH neutral adhesive used on 2 sides. May be stored in archival photo boxes like photo box "Prisma", "Spectrum" or "Illumina" - a safe and efficient combination.
