Abstract
A method for applying a metalized polymer film to a seal bag for use in a downhole submersible pumping system includes the steps of applying a metal layer to a polymer layer, applying an adhesive layer to the polymer layer, and rolling the adhesive layer onto a substrate of the seal bag. The method may also include the steps of rotating a first roller, which is located above the polymer layer of the metalized polymer film, and rotating a second roller, which is located on an interior surface of the substrate of the seal bag, in the opposite direction of the first roller. Also disclosed is a downhole pumping system that incorporates a seal bag manufactured from these techniques.
