A cellular covering for an architectural opening includes a plurality of elongated, longitudinally connected and transversely collapsible cellular units composed of inner and outer cells where the outer cell is a woven, knit, or non-woven product and the inner cell is an air-impermeable film which may be treated to be a low-modulus film with acceptable surface tension so that the panel formed from the cellular units has improved insulative properties and has a relatively long life.

1. A cellular covering for an architectural opening, said cellular covering comprising: a plurality of interconnected elongated tubular transversely collapsible outer cells forming an expandable and collapsible panel movable between extended and retracted positions,wherein:each said outer cell includes a tubular transversely collapsible inner cell secured within said outer cell by at least one adhesive line and expandable and collapsible with expanding and collapsing of said panel;said inner cell comprises a transparent or translucent orientated polypropylene film and includes a polyvinylidene chloride coating overlying at least a portion of said orientated polypropylene film and positioned between said orientated polypropylene film and said outer cell;said at least one adhesive line is positioned between said polyvinylidene chloride coating and said outer cell; andwherein said outer cells are air permeable. 2. The covering of claim 1, wherein said inner cell comprises a base layer with said orientated polypropylene film overlying at least a portion of said base layer. 3. The covering of claim 1, wherein said polyvinylidene chloride coating is positioned on an entire outer surface of said orientated polypropylene film. 4. The covering of claim 1, wherein said orientated polypropylene film has a thickness of approximately 1.5 mil. 5. The covering of claim 1, wherein said polyvinylidene chloride coating has a melting or softening point above 225° F. 6. A cellular panel for an architectural opening, said cellular panel comprising: an outer cell;an inner cell at least partially received within said outer cell, said inner cell formed of a translucent or transparent orientated polypropylene film;a layer of polyvinylidene chloride overlying an outer surface of said oriented polypropylene film and positioned between said orientated polypropylene film and said outer cell;a layer of adhesive positioned between said polyvinylidene chloride coating and said outer cell, wherein said adhesive layer secures said inner cell to said outer cell; andwherein said outer cell is air permeable. 7. The cellular panel of claim 6, wherein: said outer cell is connected to said inner cell at a first location and a second location; andsaid layer of polyvinylidene chloride is positioned on said inner cell at least at one of said first location or said second location. 8. The cellular panel of claim 7, wherein said layer of polyvinylidene chloride is positioned on said inner cell at both said first location and said second location. 9. The cellular panel of claim 7, wherein said inner cell and said outer cell are connected together by said layer of adhesive at said first location and said second location. 10. The cellular panel of claim 7, wherein said orientated polypropylene film has a thickness of approximately 1.5 mil. 11. The cellular panel of claim 7, wherein said layer of polyvinylidene chloride has a melting or softening point above 225° F. 12. The cellular panel of claim 6, wherein said outer cell includes a first crease and a second crease equally spaced from a longitudinal edge of a strip of material. 13. The cellular panel of claim 6, wherein said inner cell includes a base material, and said orientated polypropylene film overlies an outer surface of said base material. 14. A cellular shade for covering an architectural opening, said cellular shade comprising: a first cell that is translucent or transparent;a second cell at least partially received within said first cell and constructed at least in part by substantially clear orientated polypropylene film and a polyvinylidene chloride coating overlying at least a portion of said orientated polypropylene film, said polyvinylidene chloride coating positioned between said orientated polypropylene film and said first cell;an adhesive layer positioned between said polyvinylidene chloride coating and said first cell, wherein said adhesive layer secures said second cell to said first cell; andwherein said first cell is air permeable. 15. The cellular shade of claim 14, wherein said orientated polypropylene film is approximately 1.5 mil thick. 16. The cellular shade of claim 14, wherein said polyvinylidene chloride coating has a melting or softening point above 225° F. 17.
