HERMA Negative envelopes

Negative sleeves for order and overview in the archive. Perfect protection against dust and fingerprints. With Euro perforation for HERMA ring binders and all-purpose binders. Tested safety - without chemical influences on the negatives. Fileable tables of contents are included. This is a thermoplastic material. It is welded during the manufacturing process. The film is tight, so the film cannot breathe, i.e. residues of processing chemicals remain in the envelope and cannot escape. This can become visible during long-term archiving (change in the emulsion). Archiving negatives in a negative sleeve made of polypropylene film is particularly suitable for short-term archiving. - Version for: 7 x 5 - negatives: polypropylene clear - sleeves/pack: 100.
