The manufacturing method of the packaging plastic pack, the vinyl roll mounting step of mounting the vinyl fabric rolled in the form of a roll; A vinyl fabric transfer step of winding and transporting the vinyl fabric; A support insertion step of inserting the support through the side center of the vinyl surface; A heat fusion line forming step of forming a first fusion line, a second fusion line, and a third fusion line on the vinyl; A cutting step of cutting at the third fusion line point to form an inlet; It consists of a handle cutting step for cutting the handle after the cutting step.

That is, the vinyl roll mounting step is a step in which both sides are folded in the form of sigma "∑", both sides are mounted on the roller in the form of rolls, the vinyl fabric formed with the first side, the second side, the third side and the fourth side, The vinyl fabric conveying step is a step of unwinding and transporting one end of the vinyl fabric from the roller, and the support inserting step is a step of inserting the support between the first, second and third surfaces.

In the step of forming a heat fusion line, the first and second surfaces are thermally fused in a diagonal direction in units of a predetermined length, and the first and second heat fusion lines are formed by thermal fusion in the upper direction of the support, and at the same time, the third and fourth surfaces are oblique. Heat-sealing in a direction to form a second heat-sealing line by heat-sealing in the lower direction of the support, the cutting step is the point where the first heat-sealing line and the second heat-sealing line is formed along the unwinding direction of the vinyl fabric In the third heat-sealing line to form a sealing seal for forming a step, forming an opening into the opening by cutting a predetermined distance spaced apart, the cutting step is a step of cutting the handle after the cutting step.

Hereinafter, each step will be described in more detail with reference to FIG. 8.

In the vinyl roll mounting step, first, the vinyl fabric is rolled up in a roll form. At this time, when both sides of the vinyl fabric 100 are formed to face the sigma " ∑ " Two layers 11 and 12 of silver are formed, and both sides 20 are formed of four layers. For convenience of description, both side surfaces formed of four layers will be referred to as a first surface 21, a second surface 22, a third surface 23, and a fourth surface 24. The two sides of the four plies (21, 22, 23, 24) is determined according to the size of the box. That is, in a vinyl roll of the same size, if the box is large, the width of both sides is provided with a vinyl roll made narrow, and if the box is small, the width of both sides is provided with a vinyl roll made large.

And the vinyl fabric transfer step, unwinding is made from one end of the vinyl fabric mounted on the roller, the unwinded vinyl fabric is carried along a plurality of guide rods.

And, the support inserting step and the heat fusion line forming step and the cutting step, provided with the vinyl roll in the form of roll and after the transfer of the rolled vinyl fabric to cut to a certain size to produce a sickle bar, at this point cut Inserted between the first, second and third and fourth surfaces with a support, the first and second heat welding lines 31, 32 are formed in oblique directions at the top and bottom, respectively, and the heat for sealing in the vertical direction. A fusion line 33 is formed.

In more detail, when the first, second, third, and fourth surfaces 21, 22, 23, and 24 overlap with each other to form a heat fusion line without inserting a support, the first, second, third and fourth surfaces may be formed. Since all four sides stick together, the first and second surfaces 21 and 22 and the third and fourth surfaces 23 and 24 are separated by a support, thereby forming a heat fusion line. 21 and 22 are bonded to each other along the first heat welding line 31 in an oblique direction, and the third and fourth surfaces 23 and 24 are attached to each other along the second heat welding line 32 in an oblique direction. Then, to form a third heat welding line 33 in the vertical direction for sealing, the third heat welding line 33 is to form a closed part after completion of the secret pack.

When the heat fusion line (31, 32, 33) is formed as described above, the support is removed, and the plastic pack of the sickle sheet is made by cutting at a point away from the third heat fusion line (33).

The plastic pack of the sickle is in the form of a rectangular parallelepiped, and enters a cutting step of forming a hole in the center for the handle.

In the cutting step, when about 100 vinyl fabrics separated by units are stacked, the stacked bundles are moved to another table provided with cutting means, and cut by the cutting means to form a hollow handle.

Here, the press means is used as the cutting means, the shape of the handle portion can be produced in a variety of circles, ellipses and polygons.

As described above with reference to Figure 8 the action of the packaging plastic pack prepared in accordance with the present invention, first opening the inlet to both sides, the article is received through the open inlet.

At this time, both sides of the plastic pack is formed of one layer of vinyl while the four sides are unfolded, and the first and second points 41 located on the vertical surface of the first heat fusion line 31 and the second heat fusion line 32. , 42) is folded around the bottom to form a floor.

Accordingly, both sides of the bottom surface are formed in a triangular and at the same time formed in three layers, which is the first, second and third sides and the third and fourth surface forming the side is turned to the bottom surface is left in two layers, As the fifth surface 25 is overlapped on the surface, the first, second, and fifth surfaces 21, 22, and 25 and the third, fourth, and fifth surfaces 23, 24, and 25 are overlapped to form a bottom surface. The sides of the surface form a shape in which a total of three surfaces overlap.

As described above, the three surfaces form a part of the bottom surface, thereby forming a more solid bottom surface to double the force to withstand the load, thereby preventing the heat sealing line from being torn while the bottom surface of the plastic pack is separated.

In addition, in the present invention, when the box is accommodated, the edge of the box spans the first point 41, the second point 42, the third point 43, and the fourth point 44, thereby enclosing the box. This is firmly supported, and as a result, the box is stored in a plastic pack and at the same time maintains a horizontal state, even when transporting, it is more convenient to carry the horizontal state. The first point 41, the second point 42, the third point 43 and the fourth point 44 refer to the edge where the side and the bottom surface of the plastic pack meet.

In particular, the box containing the contents, such as pizza in the food may be blurred when the contents are inclined during the delivery process, the plastic pack produced by applying the present invention to keep the horizontal state firmly 4 in the process of putting the box in the plastic pack Since it is fixed to the three points can be kept in a horizontal state without tilting, and also in the process of transporting the box can be kept in a horizontal state without tilting.
