Protective Tape & Film for Archival Packaging and Storage RELIC WRAP protective PTFE tape & film is the safe way to package, archive, store and transport fine art, books and artifacts. Made in the USA, RELIC WRAP is available in three forms to allow for complete flexibility in your packaging needs. PTFE is an optimal material to provide the protective layer nearest to valuable art. It is inert, soft, flexible, temperature resistant to 550F (288C), acid-free and will not stick to the objects it is protecting. PTFE is also a thermal insulator. RELIC WRAP is completely unaffected by ultraviolet (UV) radiation, incandescent or fluorescent light exposure. It will not rot or support fungus for mildew.RELIC WRAP Packaging Film Ideal for filling voids around artifacts that are non-uniform in size, RELIC WRAP is also used as a protective layer that can be wrapped around any form of art, providing a nonstick, colorfast, conforming inner layer before additional packaging layers are applied. RELIC WRAP Film is available in rolls up to 10 wide, 0.003 thick, and 1, 000 feet in length. Technetics recommends that our PTFE tapes are stored and maintained in a controlled environment and the shelf life shall not exceed five (5) years. A controlled environment shall be clean and temperature at or below 72F (22C) with relative humidity not to exceed 50%. In addition, all material must be stored in its original condition and shipping containers. Should this become a concern, please contact us to discuss your specific requirements.
