摘要： A container comprises a substrate and a multi-layer film The substrate has a bottom wall and a continuous base wall in which the continuous base wall encompasses the bottom wall and extends upwardly therefrom. The substrate comprises at least one particulate mineral filler and polypropylene. The multi-layer film is attached to the substrate. The multi-layer film comprises at least a first layer and a second layer The first layer comprises a metallocene-catalyzed polyolefin The second layer comprises polypropylene. The substrate and the multi-layer film are made in the absence of ethylene vinyl alcohol copolymer (EVOH), ethylene vinyl acetate copolymer (EVA), and ethylene methyl acrylate copolymer (EMA).
