Abstract
A bag made of an outer bag 3 and an inner bag 2. The inner bag, inside the outer bag, has an opening in the upper edge, and the inner and outer bags are sealed along the upper edges, on either side of the respective bags, to form sealed portions 8 and 9, and the inner bag and outer bag are further sealed together at two lateral side edges and lower edge to form sealed portions 11 and 12 and sealed portion 13, thus forming gas filling compartments 14 and 15. Cut-ins 18 and 19 are formed in the upper comers of the outer bag, and supplemental sealed portions 16 and 17 connected to the sealed portions 8 and 9 are formed. Air (gas) is blown into the gas filling compartments 14 and 15 through the cut-ins and then the overall bag mouth including the cut-ins is sealed.
