Labeling artifacts and specimens can present a formidable challenge for researchers, curators, and historians, especially in archival settings. Label integrity and longevity are crucial, and these attributes can only be achieved with acid-free labels.

But what exactly is an acid-free archival label?
An acid-free label is characterized by a neutral pH level in its adhesive and face stock. Standard paper products contain a small amount of natural acid, but the bigger concern is lignin (the compound in plants that provides structure, rigidity, and durability). As lignin breaks down over time, it turns into hydrochloric acid, which can lead to chemical deterioration.
So, why are acid-free labels so important?
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.
What are the main uses for acid-free labels?
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.
How do I find high-quality acid-free labels?
Choosing which archival label is right for you depends on the level of durability that your application requires. Our semi-gloss paper option is alkaline-based (lignin-free & acid-free). This is an ideal cost-effective option; however, it is slightly less durable. If you’re looking for extra durability, our white gloss polyester option is also acid-free but has the bonus of being tear and chemical resistant.
To find high-quality acid-free labels, remember to choose materials that are both acid-free and lignin-free for long-term preservation. If you have specific requirements, consulting with a Label Expert can provide valuable guidance for your labeling project!
