Each of the funnel strips is provided along an edge which is remote from the edge connection with the companion strip, with a zig-zag edge defining a series of funnel pockets therealong. The funnel strips have bag wall film attached thereto. Then after separation of the strips and bag wall material assembly along the edge connection, the strips can be rolled-up for future use, or immediately used, by forming into individual bag sections to be filled, and the bag sections separated from the respective strips.
