Abstract (en)
[origin: FR2758761A1] The invention concerns a method for making packaging bags with lateral gussets characterised in that it comprises the following steps consisting in forming a cut (150, 160) respectively in each of the two zones forming the lateral gussets of a packaging bag sheet (100) so that the bag has only two superposed layers at the mouth of said gussets, at least over part of its width, and sealing (184, 186) the coupled edges of the sheet on the periphery of the cuts (150, 160) for closing the bag. The invention also concerns a device for implementing this method and the resulting bags.
