These sturdy folding boxes made of gray, light-resistant solid cardboard are very easy to plug together. No optical brighteners are used in their manufacture. The 35mm 35mm negative strips are best inserted into one of the leporello-like folding pockets made of unbuffered archival paper with 50% cotton content (See Accessories Item No. 28102) and then inserted into the box. 5 full sleeves of 7 6-KB negative strips each fit into one box. Paper and box are P.A.T.* - certified. We have always emphasized the benefits of high-quality plastics in photo archiving. Even more so, where paper has never really caught on due to its lack of transparency. But there are situations where other outcomes may be at the end of considerations. When the climate in the rooms varies greatly, so that the strong barrier effect of the plastics could lead to moisture forming on the object. Or if very high humidity levels prevail in the archive. But even under ideal archive conditions, there are film materials whose storage in plastic is problematic. Especially nitrate negatives and other films affected by the acetic acid syndrome can then decompose much faster. Since the degradation products do not escape, they can thus accelerate the degradation process enormously. Plastic at least protects the neighboring film much better from these degradation products. In conservation, there is hardly an advantage without a disadvantage, and it is therefore necessary to weigh up the conditions on site.
