Four Flap Negative Enclosures

 

Four-flap enclosures wrap gently around film or glass plates with no seams and no adhesives. They are offered in our traditional non-buffered, lignin-and sulfur-free .006 CRPP paper, in alkaline buffered MicroChamber paper, and in MicroChamber/Silversafe paper, a combination of the two most highly valued compositions in conservation. In the MicroChamber/Silversafe enclosures, both MicroChamber technology and Silversafe technology are integrated within one single sheet (not laminated) of paper. The patented alkaline pH 8.5 tan MicroChamber component with alkaline buffers and our proprietary hydrophobic, acid-resistant SPZ zeolite provides the finest protection available against acids, by-products of deterioration and pollutants. The white Silversafe neutral pH, non-buffered cotton layer comprising the interior surface of the enclosure provides security for those materials which may have sensitivity to alkalinity. This style of housing is available with two scores separated by 1/8 in. and 1/16 in. for glass plates, and with a single score for sheet film. Special enclosures, #4F45i-NB or #4F45i-MC, are designed for sheet film and have a 1/2 in. tab at the top. The other enclosures simply fold into rectangles. Special sizes can be fabricated upon request, so if the size you need is not listed, please contact us with your requirements. Four-flap enclosures are sold in packages of 50.
