It may be a digital world, but there’s still a lot of stuff on paper, and that’s where DuraLar Archival Film is needed!
Archival grade DuraLar polyester film is a high clarity polymer film base specifically for use in the encapsulation of paper artifacts, and document conservation. At Grafix Plastics, we follow the strict guidelines set forth by the Library of Congress to bring you an archival film that is optimal for historical document preservation and encapsulation. Further, archival grade DuraLar can be welded to itself with many of the ultrasonic welding devices used in the field.
We also offer branded archival polyester film such as MelinexTM 516 (Mylar? D replacement), HostaphanTM 4TLM, and other Library of Congress approved archival films.
