Herbarium Specimen Sheet Protectors

These sheet protectors provide vital protection for your herbarium specimens. Manufactured from soft, smooth 75 micron polypropylene, these L-sealed enclosures help keep loose plant particles from becoming separated from the specimen. In addition they provide a safe, secure environment that keeps out dirt, dust and fingerprints, while separating one specimen from another. Overall size is 11.75" x 16.75" (398 x 425mm). Designed to fit standard 11.5" x 16.5" (292 x 419mm) herbarium mounting paper. Unlike polyester enclosures, polypropylene lacks the static that can cling and damage small plant fragments.
