Abstract: A spacer includes a polymeric hollow profile, including a first and second side wall, a glazing interior wall connecting the side walls to one another; an outer wall arranged parallel to the glazing interior wall and connects the side walls to one another; a cavity surrounded by the side walls, the glazing interior wall, and the outer wall, a moisture barrier on the first side wall, the outer wall, and the second side wall, wherein the moisture barrier includes a multi-layer system having a barrier function including a polymeric layer and an inorganic barrier layer, a metallic or ceramic outer adhesive layer having a thickness of less than 100 nm, a binding layer between the adhesive layer and the multi-layer system and including a polymer selected from oriented propylene, oriented polyethylene terephthalate, biaxially oriented propylene, and biaxially oriented polyethylene terephthalate. The binding layer is directly adjacent the adhesive layer.
