Method of closing tubular bags for fruit and vegetable products

摘要

Method of closing tubular bags for fruit and vegetable products. The method comprises: 1) closing the bag which has been filled, forming a region with a structure similar to a cord by twisting or other means; 2) superimposing a laminar element which can be welded to the bag on the closure region so that the said laminar element is partially wound on the closure region of the bag surrounding it completely, the said laminar element being partially superimposed on itself at the end of the winding; 3) intimately welding the superimposed laminar element to the closure region of the mesh bag on which it has been superimposed and onto itself in the overlapping region; 4) once welded, cutting the welding region transversely, defining two closure regions at the upper end of one bag and at the lower end of the next bag.
