PermaDur Barrier Board Document Cases BlueGray
An archival storage standard, our boxes are metal edge constructed from durable 60 pt. acid-free board and buffered with 3% calcium carbonate to retard the effects of migrant acidity and atmospheric pollutants. The interior is lined in white paper and measures a pH of approximately 8.5. The metal edge we use to construct our boxes offers more "grips" per inch than many other manufacturers, creating a stronger, more durable box. Larger (5") boxes feature a black nylon cord loop that allows easier removal from shelving.
