  • Patent number: 6626312
    Abstract: A storage bag for storage and transport of a material includes an internal layer, an external layer, and an intermediate layer. The internal layer defines an interior space for storing the material and is resistant to interaction with the material. The external layer is perforation resistant. The intermediate layer is positioned between the internal layer and the external layer. Each of the layers is configured as a bag with an opening. An inlet for loading and discharge of the material into and from the interior space is provided and the internal, intermediate, and external layer openings are coupled to the inlet to allow the entrance of material into the interior space. The internal layer includes four sheets of triple layer co-extruded polyethylene. The intermediate layer is a non-woven geotextile and the external layer is a non-woven geotextile of high density polyethylene.
