Is Double Tack™ archival? No. The first rule for creating archiving materials is that the archival material can’t interfere with the thing it is protecting. DoubleTack has a stick-and-stay adhesive coating on both sides of the polyester carrier film. So it breaks that important rule! DoubleTack is pH neutral, and has good contact clarity, which makes it great for mounting documents and prints, but not for long term archiving.
How will you be using this film in an archival application? If you need a good all-around archival grade film, try our Archival Duralar™ product line, which meets the Library of Congress’ specifications for archival polyester film.
