Variable optical-property interlayer product and method for manufacturing a variable optical-property interlayer product

Abstract

A method for producing a variable optical-property interlayer product comprises providing (S10) of a variable optical-property film The variable optical-property film is placed (S30) on top of a first lamination interlayer film of a lamination inter-layer material. A second lamination interlayer film of a lamination interlayer material is positioned (S50) as to cover the variable optical-property film, thereby forming a stack. The stack is laminated (S90), forming a polymer envelope, gas-tightly encapsulating the electrochromic film. The lamination forms an outer surface of the polymer envelope as a solid/gas interface. A variable optical-property interlayer product and a packaged variable optical-property interlayer product are also disclosed. WO
