Is Acetate an archival grade film? Yes! A pH neutral film, Acetate is breathable, which means it will allow air and moisture to pass through it, making it ideal for storage applications. It will not outgas materials and it can be welded to itself. It is also a clarity film, with optical transmission > 90% and very low haze.
