Is ClearLay™ vinyl film and sheets archival? No. Over a very long time, PVC, including ClearLay, can get brittle and break down. Even though our ClearLay product is pH neutral, and can be easily welded to itself, it can out gas materials. We can not recommend this product for long term archival storage solutions.
How will you be using this film in an archival application? If you need a good, long term, “archival” grade film, try our Archival Dural™r product line, which meets the Library of Congress’ specifications for archival polyester film.
