The first side sheet includes an exteriorly oriented first pivotable flange that is distal to a first folded portion of the first side sheet. The interior facing surface of the panels of the first folded portion are bonded to one another. Optionally, the second side sheet includes an interiorly oriented second pivotable flange that is distal to a second folded portion of the second side sheet. The interior facing surface of the panels of the optional second folded portion are bonded to one another. A repositionable pressure sensitive adhesive is provided that releasably engages the first pivotable flange and the second side sheet or optional second pivotable flange. ## Claims ### Claim 1 A bag comprising: a first side sheet (20) having a pair of first side sheet transverse edges (70) and a first side sheet interior facing surface (23), wherein said first side sheet comprises an exteriorly oriented first pivotable flange (22) that is distal to a first folded portion (26) of said first side sheet and said first folded portion comprises a plurality of first panels (28) in which said first side sheet interior facing surface of said first panels are bonded to one another;
