Hereinafter, the present invention will be described in more detail and in detail. It is apparent that the present invention is not limited to the specific numerical values or concrete examples provided by the present invention, but is only for the purpose of illustrating the technical idea of the present invention in more detail as a preferred embodiment of the present invention. Further, in the specification of the present invention, a detailed description will be omitted of parts that are well known in the technical field and can be easily created by a person having ordinary skill in the art. The same reference numerals are used for the same parts. In the detailed description and the patent claims of the present invention, the term "upper surface" refers to a portion facing upward from the ground when referring to the direction of a component to be a subject, and "lower surface" means a portion facing downward from the ground do.

FIG. 1 is a schematic block diagram of a method for manufacturing a design bag according to the present invention, and FIG. 2 is a schematic explanatory view for explaining a laminating step (S 210) of a synthetic resin sheet of the present invention.

The present invention is characterized in that a synthetic paper sheet is prepared by using a top paper 110 and a bottom paper 130 and arranging and sandwiching the intermediate net paper 120 between the top paper 110 and the bottom paper 130 S 210).

The synthetic resin sheet is subjected to a lapping step (S 210) to select the top surface paper 110 constituting the outer surface of the bag body. Preferably, the topsheet 110 is a synthetic resin sheet that can be printed on the surface thereof in various shapes. As such a synthetic resin sheet, it is most preferable to use a PVA synthetic resin sheet capable of performing silk printing, offset printing, or digital printing on its surface.

It is important for the present invention to arrange the intermediate netting paper 120 having the mesh 122 immediately below the topsheet 110. In general, when the synthetic resin sheet is adhered to a high frequency, the upper surface sheet 110 and the lower surface sheet 130 are directly tasted and bonded to each other by high frequency. In the present invention, the upper surface sheet 110 and the lower surface sheet 130 Which is different from the conventional method in that it intervenes between the intermediate network 120 and the intermediate network. This is because when a high frequency bonding operation is performed in the next step due to the plurality of meshes 122 formed in the intermediate meshes 120, the upper meshes 122 and the upper meshes 122 The top surface 110 and the bottom surface 130 are adhered to each other by the meshes of the net 122 that are bonded to the bottom surface 130 .

In addition, in the present invention, the intermediate network paper 120 may be made of different materials with respect to the upper surface paper 110 when compared with the upper surface paper 110. This is because it is necessary to prevent the synthetic resin material of the upper surface sheet 110 from adhering to the meshes of the intermediate net sheet 120 when the high frequency bonding is performed. On the other hand, synthetic resin materials of the top and bottom papers 110 and 130 may be used in the same manner. So that they can be adhered to each other through the empty space of the mesh 122 of the intermediate network 120.

In the present invention, the base paper 130 is arranged immediately below the intermediate network paper 120. The base paper 130 forms an inner skin of the bag body when the base paper 130 is bonded at a high frequency. The bottom surface 130 is preferably made of a synthetic resin sheet.

In the present invention, the upper surface paper 110, the intermediate paper web 120, and the lower surface paper 130 are sequentially arranged and joined together.

3B is a schematic view illustrating a high-frequency bonding step S220 of the present invention. FIG. 3A is a schematic view showing a preparation state of a high-frequency bonding step S220, FIG. 3B is a high- And FIG. 3C is a schematic cross-sectional view of the synthetic resin fabric after the high-frequency bonding step (S 220) is performed.

The high frequency bonding step (S 220) of the synthetic resin sheet for performing the bonding operation using the high frequency mold in a state where the upper surface paper 110, the intermediate paper web 120 and the lower surface paper 130 are laminated .

The high frequency bonding step (S 220) of the synthetic resin sheet is performed by using a high frequency mold in a state where the upper surface paper 110, the intermediate paper web 120, and the lower surface paper 130 are laminated.

The high-frequency bonding operation can be performed by placing the synthetic resin cloth, which is preliminarily stuck on the high-frequency device. In this case, the high frequency die 50 is positioned above the upper surface sheet 110, and the upper surface sheet 110 and the lower surface sheet 130 are bonded to each other by high frequency heating. The high frequency mold 50 has adhesive blades 52a and 52b having widths or spacing D of 2 mm to 7 mm in both left and right directions and the adhesive blades 52a and 52b And an end portion thereof forms an inclined surface 54. The inclined surface 54 may be formed on one or both sides. In the drawings of the present invention, it is shown that only one side is formed with the inclined surface 54, but this is an exemplary one.

The adhesive blades 52a and 52b can form a sloped surface 54 at the end thereof to supply a larger amount of heat of high temperature to the synthetic resin sheet of the top paper 110 to improve the adhesive efficiency, It is possible to form a highly elaborate and smooth cut surface by using the sharp end face of the end. Further, since the adhesive blades 52a and 52b are arranged in the left-right direction while being paired with each other and forming a width or a distance D of 2 mm to 7 mm, after the adhesive operation is performed, The adhesive band 114 is formed in the left and right direction on the surface of the adhesive layer 110, and the top surface removing band 116 is formed therebetween.

Due to the double action of the inclined surface 54 of the adhesive blade 52, the present invention can efficiently transfer the adhesive heat of high temperature to the top surface paper 110, and can easily transfer the top surface removing belt 116 It will provide a foundation that can be removed, removed or cut off. The plastic material of the synthetic resin sheet of the upper surface sheet 110 is melted and adhered to the lower surface sheet 130. As a result,

Meanwhile, since the intermediate network 120 has a plurality of networks 122, the upper and lower surfaces 110 and 130 are adhered to each other via the voids of the network 122, The mesh 124 constituting the mesh 122 interferes with the adhesion between the upper surface 110 and the lower surface 130. The top surface 110 and the bottom surface 130 form an adhesive portion 112 to be adhered to each other in the region of the void space of the net 122. However, 124 are not adhered to each other.

The upper surface sheet 110 is formed with adhesive strips 114 formed in parallel to each other with a spacing distance D of 2 mm to 7 mm corresponding to the inclined surfaces 54 of the adhesive blades 52a and 52b And an upper surface removing band 116 is formed between the adhesive band 114 and the adhesive band 114. [ At this time, it is natural that the adhesive portion 112 exists inside the lower portion of the adhesive band 114.

5 is a schematic view showing an embodiment of the synthetic resin fabric 100 obtained after the design forming step S 230 of the surface of the top paper 110 is performed.

A plurality of polygonal shapes 117 are formed on the surface of the topsheet 110 by removing and removing the tops removing strips 116 formed between the adhesive strips 114 on the surface of the topsheet 110, (S 230) of the upper surface of the paper.

The design forming step S 230 of the upper surface supporting surface may include a bonding band 114 formed by the bonding blades 52a and 52b on the surface of the upper surface sheet 110 after the high frequency bonding step is completed, The upper surface removing belt 116 is formed between the upper surface removing belt 116 and the upper surface removing belt 116. The upper surface removing belt 116 may be peeled from the surface of the upper surface paper 110 in the order.

When the upper surface sheet 110 and the lower surface sheet 130 are adhered to each other by the adhesive blades 52a and 52b, two rows of adhesive sheets 52a and 52b formed by the inclined surfaces 54 of the adhesive blades 52a and 52b The adhesive band 114 is obtained and the top surface removing band 116 formed elongated along the short width D of the adhesive band 114 is obtained. The top surface removing strips 116 are elongated in a linear direction on the surface of the top surface 110 and are connected to each other. When the operator removes the top surface removing band 116 and removes the top surface removing band 116, a plurality of polygonal shapes 117 are formed on the surface of the top surface 110. The shape 117 of the polygon is shaped like a triangle, a rectangle, a pentagon, a hexagon, an octagon, a circle, or the like. The portion where the triangle and the quadrangle intersect with each other may include a circular or pentagonal star shape. The polygonal shape 117 may be designed in the mold design stage of the adhesive blades 52a and 52b.

After completing the above steps, the synthetic resin fabric 100 for bag manufacturing is completed. The shape of the top surface removing band 116 formed on the surface of the top paper 110 can be changed by arranging the bonding blades 52a and 52b of the high frequency mold 50, The shape of the polygon 117 can be formed differently.
