An order of several 8x10 and 4x5 boxes of film, along with archival film storage sleeves arrived absolutely covered in Kodak Hypo Clear powder from a broken Kodak Hypo Clear packed that was also housed within the same package. The powder has made its way throughout the package and is even between the film box cover/seam.

Is the film salvageable? (Not sure whether it is fully sealed or just sleeved within the film box?)
