Abstract
A pre-glued, flat folding box contains a section of tubular film (5) glued to the box to form an inner bag. The tubular film section has bending lines (8,9) in all four corners of the body of the folding box which extend to the edges of the section of tubular film. This makes it easier to erect the folding box containing the section of tubular film and to fill and close the package.
