Is Clear DuraLar™ archival? Yes and no. There are three aspects that go into determining whether a polyester film is actually archival grade: 1- whether it is pH neutral, 2- whether or not the film will impact what it comes in contact with, and 3- whether it can be sonically welded to itself. Clear DuraLar is pH neutral, and will not stick or transfer to other surfaces. Unfortunately, it is not treated so that it may be sonic-ally welded to itself.
How will you be using this film in an archival application? If you only need a high clarity, pH neutral film, Clear DuraLar is an excellent choice. If you also need to sonically weld the film, try our Archival Duralar™ product line, which meets the Library of Congress’ specifications for archival polyester film.
