Is PSA Duralar™ archival? No. Pressure-sensitive adhesive (PSA) Duralar has a stick-and-stay adhesive coating on one side; it breaks the number one rule of archiving – material used for archiving can’t interfere with the materials it is supposed to protect. PSA DuraLar is pH neutral, and water clear, which makes it great for lamination and surface protection, but not for long term archiving.
