Method and constructions for moisture sensitive layers and structures having reduced moisture content in moisture sensitive layers

摘要

Alternating layers of a first moisture sensitive layer are formed with a second desiccant containing layer. The desiccant containing layer removes moisture from the first moisture sensitive layer and maintains the first layer in a relatively dry condition.

主权项

1. A roll of alternating layers of films or sheets for storage and/or shipment of an interlayer film comprising:
an interlayer film comprising PVB or ethylene vinyl acetate; and a desiccant-containing film juxtaposed with the interlayer film; wherein the juxtaposed interlayer film and the desiccant-containing film are wound into a roll of alternating layers wherein the interlayer film and the desiccant-containing film directly contact each other; wherein the desiccant-containing film prevents the blocking of the interlayer film; wherein the desiccant-containing film is capable of removing moisture from the interlayer film; and wherein the desiccant-containing film is readily removable from the interlayer film to recover the interlayer film.
