The gray-blue acid-free permanent archival cardboard in sheets is characterized by a refined surface that repels dirt and is resistant to wear. Thanks to the high proportion of long fibres, cardboard is excellent for making sleeves, folders or covers. This buffered cardboard does not contain lignin and can be used not only for the storage of valuable books, but also for the separation of works of art and photographs, as it has passed the PAT – photographic activity test . Does not contain optical brighteners.
