This method is designed to protect fragile or damaged specimen labels, whether detached or still tied to specimens. This system allows labels to be viewed from both sides without direct handling, and because the labels are not sealed in the envelope, they are accessible for annotation if necessary. The technique can be used to protect labels of almost any material, including paper, metal, or plastic; however, the media on parchment labels could be damaged by static electricity generated by the polyester film. The care of parchment labels should be referred to a trained conservator.
