ULTRASONIC ENCAPSULATION
|
| |
A method of single-sheet paper support that has won favor
in recent years because of its total reversibility is polyester
film encapsulation. In this method, the damaged sheet is
sandwiched between two sheets of polyester film (Mylar® type
D or Melinex® type 516). The film should not contain
plasticizers or surface coating, or be a plastic other than
polyester. The film is sealed around the edge using either
double-sided adhesive tape, heat welding, sewing, or ultra-sonic
welding.
The ultrasonic machine welds the polyester with a head that moves
across it at a regulated speed. The advantage of ultrasound is
that a weld may be placed at any point on the polyester—not
just the edge—and it doesn't cause thickening.
