A clear, flexible, sealed container may be made of first and second plastic sheets sealed together at their peripheries. The first plastic sheet defines a bulge to increase the inside volume of the container, and comprises a laminate of a layer of polyolefin and a blended layer of polyolefin and a block copolymer of polyolefin and polystyrene. The second plastic sheet is a bonded laminate of a layer of biaxially oriented polypropylene and nonoriented polypropylene, peripherally bonded to the layer of polyolefin of the first plastic sheet. |
