A large bulk bag formed from a tubular blank of woven fabric having inwardly folded gusset panels along opposite side edges. While in the flattened condition, the blank is sewn along predetermined stitch lines and severed at predetermined portions so that, when the stitched and severed blank is expanded, it forms a bag of rectangular cross section having closable spouts at one or both ends. If a liner is to be used in the bag the liner is formed from a gussetted tubular blank and sealed along lines corresponding to the stitch lines on the bag so that the flat liner can be inserted into the flattened bag with the gussetted portions of the bag and liner interfitting in interleaved relation. |
