The tubular body has a larger open diameter at the top open end. The tubular body narrows into a narrower open diameter adjacent to a bottom closed end. The tubular body in a flattened two-fold condition has a pair of side edges extending from a top edge to a bottom edge. The top edge delimits the top open end. The bottom edge delimits the bottom closed end. The pair of side edges are generally parallel to one another in a first portion adjacent to the top edge. ## Claims ### Claim 1 A bag comprising a tubular body made of film, the tubular body having a first portion and a second portion, the first portion defining a top open end and the second portion defining a bottom closed end, the tubular body in a flattened two-fold condition having a pair of side edges extending from the top open end to the bottom closed end, the pair of side edges being generally parallel to one another between the top open end and the bottom closed end and delimiting an interior of the tubular body, the tubular body having a larger open diameter at the top open end, and a narrower open diameter in the second portion, at least one weld seam defining the narrower open diameter, the at least one weld seam and at least one of the side edges defining at least one flap therebetween, the at least one flap being excluded from the narrower open diameter. ### Claim 2 (depends on 1) The bag according to claim 1, wherein the tubular body is made of at least two layers of film. ### Claim 3 (depends on 2) The bag according to claim 2, wherein at least one of the layers is an ethylene vinyl alcohol. ### Claim 4 (depends on 1) The bag according to claim 1, wherein the top open end and the bottom closed end are defined by straight edges. ### Claim 5 (depends on 1) The bag according to claim 1, wherein a relation between a flattened two-fold width WA of the larger open diameter and a flattened two-fold width WC of the narrower open diameter is expressed as 0.60WA≤WC≤0.95WA. ### Claim 6 (depends on 1) The bag according to claim 1, including a pair of the at least one weld seam. ### Claim 7 (depends on 6) The bag according to claim 6, further including a pair of the at least one flap. ### Claim 8 (depends on 1) A bag roll comprising: a plurality of the bag according to claim 1, wherein the bags are connected end to end and from the bottom edge of a first of the bags in the bag roll, to the top edge of a second of the bags in the bag roll. ### Claim 9 (depends on 8) The bag roll according to claim 8, wherein the bag roll is in a receptacle of a cassette body, a free end of the bag roll exiting the cassette body from a top opening in the receptacle. ### Claim 10 (depends on 8) The bag roll according to claim 8, wherein the bags are made of a continuous tubular body separated by a weld seam and a tear line at a bottom edge of each of the bags. ### Claim 11 (depends on 8) The bag roll according to claim 8, including a pair of the at least one weld seam defining the flap. ### Claim 12 (depends on 11) The bag roll according to claim 11, further including a pair of the at least one flap. ### Claim 13 (depends on 10) The bag roll according to claim 10, wherein the tubular body is made of at least two layers of film. ### Claim 14 (depends on 13) The bag roll according to claim 13, wherein at least one of the layers is an ethylene vinyl alcohol. ### Claim 15 (depends on 13) The bag roll according to claim 13, wherein at least one of the layers is made of at least one of polyethylene, bioplastic, polyactic acid, starch-base, plant-base. ### Claim 16 (depends on 8) The bag roll according to claim 8, wherein a relation between the flattened two-fold width WA of the larger open diameter and the flattened two-fold width WC of the narrower open diameter is expressed as 0.60WA≤WC≤0.95WA. ### Claim 17 (depends on 8) The bag roll according to claim 8, wherein the top open end and the bottom closed end of each said bag are defined by straight edges.
