But what exactly is an acid-free archival label? 


The effects of chemical deterioration in the labeling world can include yellowing, staining, brittleness, and curling, all of which are highly undesirable when your goal is long-term preservation!  When it comes to manufacturing archival labels, it’s crucial to pay attention to the adhesive and face stock of the label.  We choose materials where the acid and lignin properties are eliminated from the pulp during processing.  This is critical for archival storage because it is the only way to ensure the stored materials remain in top condition.  Our archival labels maintain their integrity during long-term storage. without causing any damage to the important artifact or document to which it is applied. 

Industry professionals handling collections, artifacts, and archival materials rely on acid-free labels for preservation.  Collection managers, curators, archivists, librarians, archeologists, registrars, forensic teams, and entomologists are a few examples of professionals we serve.  Whether in artwork and museums, laboratories, or specimen storage, using acid-free materials is crucial to prevent deterioration over time.
