Liners or bags and method of making them

A method of forming a plurality of interconnected flexible containers from an elongated blank of material, the method comprising the steps of:

• providing the blank in gusseted form with a pair of gusset panels disposed between a pair of overlying flat panels;
• forming a wall of a first container by connecting each flat panel to an adjacent portion of each gusset panel along at least one inclined line forming interconnected triangular portions;
• forming a wall of a second container spaced from the wall of the first container by connecting each flat panel to the adjacent portion of each gusset panel along at least one inclined line forming interconnected triangular portions;
• providing at least one tear line extending between and connecting corresponding inclined lines of the walls of the first container and second container and defining an interconnecting section of the blank on one side of said at least one tear line and between the walls of the first and second containers whereby, scrap material on the other side of said at least one tear line may be removed from the blank without removing the interconnecting section of the blank to prevent complete separation of the blank between the walls of the first and second containers.
