context_page_description: The storage of cultural heritage objects typically falls to the responsibility of cultural heritage institutions, or individuals. The proper storage of these objects can help to ensure a longer lifespan for the object with minimal damage or degradation. With so many different types of artifacts, materials, and combinations of materials, keepers of these artifacts often have considerable knowledge of the best practices in storing these objects to preserve their original state.
context_section_description: All paper products will acidify over time, so even archival acid-free paper products used for storage are typically replaced every few years. Archival acid-free paper products can be either buffered or unbuffered. Unbuffered paper has a neutral pH and is used for housing photographs, textiles, and most other types of objects, while buffered paper, which is impregnated with calcium carbonate and has an alkaline pH, is used for storing paper objects. The buffered paper absorbs the acid that paper objects emit and keeps the micro-environment from becoming overly acidic for a longer period of time.
  Acid-free glassine paper is typically used to cover friable materials or objects with oily/tacky surfaces, as it is smooth and does not create static electricity, though it is only used for short periods of time because it deteriorates quickly.
  Soft unbuffered acid-free tissue paper is used for covering a variety of objects, creating padding in boxes, and for placing in the folds of textiles to prevent creasing.
  Acid-free folders are valuable for storing unframed prints and documents in flat files.
