Encapsulation:  Using the Ultrasonic Welder for Polyester Film Encapsulation, we can seal fragile materials between sheets of polyester film, which support brittle paper to avoid wear and tear and keeps it from being exposed to air which may cause further damage. The encapsulator can secure any document from the size of a postage stamp to a 42 inch oversized wall map. It is also capable of internal, spot, and free-form wells, allowing multiple documents and irregularly sized objects to be encapsulated in separate pockets on a single large polyester sheet.
