## Summary
Encapsulation is a preservation technique in archival science that involves sealing documents between two sheets of plastic to protect them from damage and deterioration. This method is used to prolong the life of records and objects in museums, libraries, and archives. It is a specific activity within the broader field of preservation.

## Key Facts
- Encapsulation is a subclass of preservation, which is a set of activities aimed at prolonging the life of records or objects.
- The technique involves sealing documents between two sheets of plastic for protection.
- Encapsulation is documented in the Dictionary of Archives Terminology with the ID "encapsulation."
- The Wikidata description for encapsulation specifies its use in archival science for preservation purposes.
- The technique is referenced in academic sources, including a 2023-04-17 entry in Wikidata.

## FAQs
### Q: What is encapsulation in archival science?
A: Encapsulation is a preservation technique where documents are sealed between two sheets of plastic to protect them from damage and deterioration. It is used to prolong the life of records in museums, libraries, and archives.

### Q: How does encapsulation differ from other preservation methods?
A: Encapsulation specifically involves sealing documents between plastic sheets, whereas other preservation methods may include cleaning, repairing, or storing items in controlled environments. It is a targeted approach to protect fragile documents.

### Q: Why is encapsulation important for archival materials?
A: Encapsulation is important because it provides a physical barrier against environmental factors like dust, moisture, and handling, which can cause damage to archival materials. It helps ensure the longevity of valuable records.

## Why It Matters
Encapsulation plays a critical role in archival science by providing a reliable method to protect fragile documents from physical and environmental damage. This technique ensures that historical records, manuscripts, and other valuable materials remain intact for future generations. By sealing documents between plastic sheets, encapsulation prevents deterioration caused by handling, dust, and moisture, which are common threats in archival settings. Its significance lies in its ability to extend the lifespan of records, making it an essential tool for museums, libraries, and archives. Without such preservation methods, many important documents could be lost or rendered unreadable over time, erasing vital pieces of history.

## Notable For
- Specific use in archival science for document preservation.
- Involves sealing documents between two plastic sheets for protection.
- Recognized in the Dictionary of Archives Terminology.
- Documented in Wikidata with a detailed description.
- Referenced in academic sources as a subclass of preservation.

## Body
### Definition and Purpose
Encapsulation is a preservation technique used in archival science to protect documents by sealing them between two sheets of plastic. This method is designed to prevent physical and environmental damage, ensuring the longevity of records.

### Materials and Process
The process involves using plastic sheets, typically polyester or Mylar, to create a sealed enclosure around the document. This barrier protects against dust, moisture, and handling, which are common causes of deterioration.

### Applications
Encapsulation is widely used in museums, libraries, and archives to preserve fragile documents, manuscripts, and other valuable materials. It is particularly useful for items that are frequently handled or exposed to environmental risks.

### Advantages
The technique offers several advantages, including reversibility, as the document can be removed from the plastic if needed. It also provides a clear view of the document without direct contact, reducing the risk of damage.

### Limitations
While effective, encapsulation is not suitable for all types of documents. For example, items with friable media (e.g., charcoal or pastel) may be damaged by static electricity from the plastic. Additionally, the process requires careful handling to avoid trapping moisture or debris.
