Apparatus For Producing Bags With Three Dimensional Designs

Abstract

The bag-making packaging machine 20 comprises a tubular former 23 having a former surface for aligning a packaging film 11, a pull-down mechanism 24, a vertical seal mechanism 21, a horizontal seal mechanism 22, and a molding apparatus 25 for molding three dimensional designs, in which the tubular former 23 has a molding surface 30 for molding the three dimensional designs at any position of the former surface, and the molding apparatus 25 is provided at the position opposite to the molding surface 30 of the former. As specific examples of the molding apparatus 25, a heater, a light irradiation apparatus, a mold, and pressing machine can be exemplified. When the molding apparatus 25 is the heater or the optical irradiation apparatus, a foamable ink is contained in the printing layer of the packaging film 11 to foam. When the molding apparatus 25 is the mold, the embossing is performed by further laminating the reinforcement sheet or the sheet for the three dimensional designs on the packaging film 11. And when the molding apparatus 25 is the pressing machine, the three dimensional sheet is laminated on the packaging film 11 beforehand.
