And when manufacturing the packaging bag 10 each having a bonding portion (14, 14 ') on both sides there will be a double-sided tape attaching process (S3) and there is only a difference there will be described at the same time their manufacturing process.

5 and 6, the fabric bonding process (S1) of the present invention, the envelope envelope (11 ') of the outer roll roll 110 and the air cap sheet 11 "is wound around the air cap The envelope envelope 11 'and the air cap sheet 11 "are respectively unrolled from the trawl 110' and are transported in a state where they overlap each other in the lamination roller 111.

Meanwhile, in the present invention, the main body 100 in which the respective devices or means are supported and installed will not be shown in the detailed drawings or descriptions to help the present invention.

Therefore, the envelope envelope 11 'used in the present invention is mainly used a sheet of polyethylene resin material which is a material that melts when heat is applied.

As shown in FIG. 6, the air cap sheet 11 ″ includes a bubble paper 11a made of polyethylene resin, which is a material that melts heat, and a base paper 11b, which is a material that does not melt even under heat. It is to be provided with a plurality of bubbles (11c) filled with air (a) on the), such an air cap sheet (11 ") is already known and ready-to-use is used to buy.

Therefore, in the lamination roller 111, the bubble paper 11a of the air cap sheet 11 "is brought into a state of being brought into surface contact with one surface of the envelope envelope 11 ', and is conveyed as described above. The 11 'and the air cap sheet 11 " are conveyed by a pulling force pulled from the fabric bonding means 120 provided at the front side.

The fabric bonding means 120 is provided with a heating roller 121 and a pressure roller 123 interlocked by the roller driving means 101.

In addition, the roller driving means 101 is a pair of feed each fixed to each roller shaft 104 as the pair of gears 103 are rotated to be interlocked by the reduction motor 102 power as shown in FIG. The roller 110 is to be interlocked. Reference numeral 105 denotes a chain gear, and reference numeral 106 denotes a chain.

On the other hand, since the roller driving means 101 of the other interlocking rollers described in the present invention is also the same as the roller driving means 101 described above, detailed drawings and description of the roller driving means 101 will be omitted below. do.

And the guide rollers or tension rollers for conveying in the present invention shown in the drawings, but these guide rollers or tension rollers are already known, so that the reference numerals or detailed descriptions are omitted for the purpose of understanding the present invention and only those related to the present invention will be described. It will be described below.

Referring back to FIG. 6, the envelope envelope 11 ′ and the air cap sheet 11 ″ merged so as to be superimposed on the lamination roller 111 are the heating roller 121 and the pressure roller 123 of the fabric bonding means 120. It is transferred to the pulling force to be pulled by the rotational force of the state is joined to each other.

 The fabric bonding means 120 is composed of a heating roller 121 in which a plurality of rod heaters 122 are built, and a pressure roller 123 corresponding thereto.

In addition, one side of the heating roller 121 is a pair of pieces of fingertips 124 receiving the electrical energy from the control unit 200 supplies the electrical energy to the ground ring 126 fixed to the rotary hole 125, the ground The electric wire 127 connected to the ring 126 is configured to supply the electric energy to the rod heater 122 through the roller shaft 104, so that the electric energy is generated in the rod heater 122 while the heating roller 121 is rotated. It is possible to supply.

The pressure roller 123 is configured such that the roller shaft 104 is rotatable in the movable member 108, the movable member 108 is configured to be movable in the vertical direction by the operation of the height adjustment bolt 109. By providing the roller height adjusting means 107 is to be able to adjust the interval between the heating roller 121 and the pressure roller 123.

The roller height adjusting means 107 of the pressure roller 123 is a known technique which is installed on both sides of the pressure roller 123, so another known roller height adjusting means may be employed. will be.

Therefore, the pressure roller 123 is to adjust the height so as to be in a state capable of pressing the air cap sheet (11 "), at this time the pressing force is such that the bubble (11c) of the air cap sheet (11") does not burst To be controlled to work.

As the electric energy is supplied to the rod heater 122 by the command of the controller 200, the rod heater 122 emits heat energy, thereby heating the heating roller 121.

In the control unit 200, the heating temperature of the rod heater 122 in a state suitable for the bonding temperature of the envelope envelope 11 'and the air cap sheet 11 "is preset.

Therefore, when the temperature is greater than the preset junction temperature, the temperature sensor 128 detects this and applies a detection signal to the control unit 200 through the sensing bombardment piece 124 ′ in contact with the ground ring 126.

Accordingly, the control unit 200 cuts off the electric energy supplied to the rod heater 122 when the heating roller 121 is heated above the junction temperature, and conversely, when the heating roller 121 falls below the junction temperature, the rod heater 122 By supplying electrical energy back to the heating roller 121, the heating roller 121 always maintains a good bonding temperature for bonding the envelope envelope 11 'and the air cap sheet 11 "during operation.

The bonding temperature of the heating roller 121, which is good for bonding the envelope envelope 11 'and the air cap sheet 11 ", is preferably 120-140 ° C, but in some cases, the envelope envelope 11' and the air cap sheet If there is a material change of (11 "), it is possible to change the junction temperature in the control unit 200 according to the material to be activated.

On the other hand, the present invention is for packaging having a sealing portion 12, such as the packaging bag 10 shown in Figure 2 in bonding the envelope envelope 11 'and the air cap sheet 11 "by the fabric bonding means 120 In the case of producing the envelope 10, as shown in (a) of FIG. 9, the width Lb of the envelope envelope 11 'is longer than the width La of the air cap sheet 11 "so that the envelope envelope ( 11 ') and the air cap sheet 11 " overlap each other so that the portion to be bonded is joined by the width La of the air cap sheet 11 " so that the air cap sheet 11 when the packaging bag 10 is completed later The " K " portion of the envelope envelope 11 ', to which the "

In the case of producing the packaging bag 10 'without the seal 12 described above and having only the bonding parts 14 and 14' on both sides, as shown in the packaging bag 10 'shown in FIG. As shown in the figure, the envelopes 11 'and the widths La and Lb of the air cap sheet 11 " have the same dimensions so as to be bonded to each other by the fabric bonding means 120 in a state where they overlap each other. .

Of course, in the case of producing the packaging bag 10 having the sealing portion 12 shown in FIG. 2, only such packaging bag 10 is continuously manufactured, and even in the case of the packaging bag 10 'shown in FIG. By continuously producing only 10 ', the packaging bag 10 having the sealing portion 12 shown in FIG. 2 can also be manufactured by one manufacturing apparatus, and the packaging bag 10' shown in FIG. It is possible to manufacture.

Therefore, in the present invention, when the envelope bonding means 120 passes through the envelope envelope 11 'and the air cap sheet 11 ", the envelope envelope 11' and the air cap sheet 11" are shown in FIG. The bubble paper 11a is bonded to each other by heat fusion, thereby becoming a state of forming the support support 11.

The present invention is carried out the air cooling process (S2) in the following process.

The air-cooling process (S2) is a process of releasing the thermal energy held by the support support 11 itself to the outside by the heat-sealed the support support (11).

For the purpose of understanding the present invention, for example, if the heat support retained by the support support 11 is not released to the outside, the support support 11 may be relaxed so that the dimensions of the packaging bags 10 and 10 'may be changed. Errors can occur when the process is in progress.

In addition, in the case of cooling by the cooling water circulated to the cooling plate as in the past, the temperature at which the support stage is partially cooled by generating a higher temperature difference due to the absorption of the cooling energy circulated and drained more than the initial cooling water temperature. As the difference occurs, the support ends are unevenly cooled, so a difference occurs in the degree of partial shrinkage, and in severe cases, the shrinkage imbalance phenomenon is caused in which the portion is squashed unevenly.

Therefore, the present invention is configured to have a natural cooling section 130 having a long length between the fabric bonding means 120 and the section feed roller 140 to be naturally cooled at room temperature.

Therefore, in the present invention, the natural cooling section 130 between the fabric bonding means 120 and the feed roller 110 is naturally cooled by room temperature air in the process of transporting the support support 11.

When the natural cooling section 130 has a length of about 1-1.5 meters, it was found that the measured temperature of the haptic support 11 cooled at room temperature of 18-20 ° C was about 26-35 ° C. In the case of the temperature of the support group 11 is shown that almost does not relax.

And the present invention may be able to adjust the length of the section of the natural cooling section 130 because the indoor temperature of the summer season and the winter season may be different.

The section length adjustment structure is to be installed in the main body 100 portion having a natural cooling section 130, the structure to be adjusted in this way is already known in a variety of ways, so detailed drawings and descriptions are omitted. Let's do it.

At the point where the natural cooling section 130 ends, a pair of section feed rollers 140 are provided.

The pair of section feed roller 140 is to be interlocked by the roller driving means 101 as shown in Figure 7, it has already been described, so the detailed description thereof will be omitted.

The pair of section feed rollers 140 serves to naturally pull the haptic support 11 bonded by the fabric bonding means 120 to be transported.

Therefore, the present invention is rotated so that the rotational speed of the pair of section feed roller 140 has a relatively low rotational speed than the rotational speed of the heating roller 121 and the pressure roller 123 of the fabric bonding means 120.

Of course, the production speed is not significantly slowed down because the pair of section feed rollers 140 are rotated at a low rotational speed that is slightly different than the rotational speed of the heating roller 121 and the pressure roller 123. .

Therefore, when the pair of section feed rollers 140 are rotated at a relatively low speed than the rotational speeds of the heating rollers 121 and the pressure rollers 123, the support ends 11 conveyed from the natural cooling section 130 are pulled tight. Since the support stage 11 is not relaxed in the air-cooling process (S2) because it is not in a state of being unsupported, it is not known that the support-support stage 11 transferred to the air-cooling process (S2) sags downward. In order to prevent it, it is preferable that the conveyance guide member 131 is installed below the haptic end 11 conveyed by the natural cooling section 130.

Next, the present invention is to produce a double-sided tape attaching process (S3) when producing a packaging bag 10 having a sealing portion 12 as shown in Figure 2 and 9 (a), Figure 3 As shown in (b) of FIG. 9, when the packaging bag 10 ′ having only the bonding parts 14 and 14 ′ is produced at both sides, the double-sided tape attaching process S3 is omitted and the half folding process S4 is immediately performed. This is to be done.

First, as shown in (a) of FIG. 2 and FIG. 9, a double-sided tape attaching process S3 when producing a packaging bag 10 having a sealing portion 12 will be described.

5 and 6, the present invention includes a double-sided tape attachment means 150.

The double-sided tape attaching means 150 is a release paper 13a of the double-sided tape 13 which is unwound from the double-sided tape winding roll 153 in which the double-sided tape 13 with the release paper 13a attached to one side thereof is wound. The double-sided tape 13 is attached to the sealing portion 12 of the haptic end 11 which is brought into close contact with the u-turn roller 152 and is conveyed in the direction in which the haptic end 11 is conveyed along the fabric support guide roller 151. It is configured to be.

Therefore, since the haptic end 11 is conveyed with the double-sided tape 13 attached to the sealing portion 12 of the haptic end 11 to be conveyed as shown in FIGS. 10 (a) and 10 (b). As the double-sided tape 13 is attached to the sealing portion 12 of the haptic support 11, the pulling force is generated on the double-sided tape 13 which is wound around the U-turn roller 152. As the double-sided tape 13 is automatically released from the take-up roll 153, the double-sided tape 13 is continuously attached to the sealing portion 12 of the support support 11 without a separate power.

In addition, since the double-sided tape 13 is continuously attached to the sealing portion 12 of the support support 11 without additional power, the state in which the support support 11 is conveyed satisfactorily without affecting the flow to which the support 11 is transported is maintained. Will be.

Next, when the present invention produces a packaging bag 10 having a sealing portion 12 as shown in (a) of Figure 2 and 9 (S3) is carried out as follows When the half folding process (S4) is carried out, and as shown in (b) of Fig. 3 and 9 (b) to produce a packaging bag 10 'having only the junctions 14, 14' on both sides, Immediately in S2) the folding process (S4) is performed.

5 and 11, the half folding process (S4) of the present invention is a process for folding the haptic support 11 in half using the half folding means 160. At this time, in the case of the support end 11 having the sealing portion 12 having the double-sided tape 13 attached, the sealing portion 12 is not folded in half, but the envelope shell 11 'and the air cap sheet 11 Only the portion of the haptic end 11 of the portion where "" is joined is folded in half, and the same is true of the haptic end 11 without the sealing part 12.

That is, referring to FIG. 12, the sealing part 12 remains intact and the portion of the haptic support 11 of the portion where the envelope envelope 11 ′ and the air cap sheet 11 ″ are joined is folded in half. Will be.

Referring to FIGS. 11 and 13, the semi-folding means 160 moves downwardly when the haptic support 11 moves close to the tripod 162 through the idle roller 161 and moves downward. It will be folded into a triangular shape is pressed by a pair of half-rolling roller 163 is to be completely folded in half.

Since the half folding means 160 is a known one already used in the known conventional bag manufacturing apparatus, a detailed description thereof will be omitted.

Meanwhile, in the present invention, a state in which the haptic support 11 is completely folded in half as shown in FIG. 14 by the half-folding means 160 will be referred to as a half-folding fabric 11A.

Therefore, the present invention is in a state in which the support stage 11 is folded in half when the half folding process (S4) is completed, as shown in Figs. 2 and 9 (a) is provided with a sealing portion 12 In the case of the packaging bag 10 to be folded as shown in (a) and (b) of FIG. 14 except for the portion of the sealing portion 12 to which the double-sided tape 13 is attached, the other half is folded in half. In the case of the packaging bag 10 'having only the joints 14 and 14' at both sides as shown in Figs. 3 and 9B, as shown in Figs. As will be a half folded fabric (11A) is the whole is folded in half.

In the semi-folding fabric 11A, the envelope envelope 11 'is exposed to the outside and the air cap sheet 11 "is folded in a state concealed inside.

Therefore, the semi-folding fabric 11A is passed to the bubble removing means 180 where the bubble preheating removing process S5 is performed through the distal end waiting means 170.

The distal end waiting means 170 is provided with a deflection member 173 which is rotated in the up and down directions about the hinge shaft 172 below the plurality of guide rollers 171, as shown in FIG. The deflection member 173 is provided with a plurality of flow rollers 174 in the longitudinal direction so that the semi-folding fabric 11A is zigzagly transferred between the plurality of guide rollers 171 and the flow rollers 174.

Therefore, in the present invention, the semi-folding fabric 11A is continuously transported in the semi-folding means 160, while in the bubble removing means 180, the semi-folding fabric 11A is temporarily removed for removing the bubbles 11c. Will be in a stopped state.

Therefore, when the semi-folding fabric 11A is temporarily stopped to remove the bubble 11c from the bubble removing means 180, the semi-folding fabric 11A is continuously conveyed from the half-folding means 160. The semi-folding fabric 11A in the distal end waiting means 170 is in a stretched state, and at this time, the deflection member 173 is rotated downward as shown in the imaginary line of FIG. The half-folding fabric (11A) to be hung on 174 is to be temporarily waiting while receiving the half-folding fabric (11A) that is conveyed from the half-folding means 160 while maintaining a tense state.

After the bubble 11c is removed from the bubble removing means 180, the semi-folded fabric 11A is temporarily transferred again and stopped again.

At this time, when the semi-folding fabric 11A is temporarily transferred again, the semi-folding fabric 11A in the far end temporary waiting means 170 is pulled toward the bubble removing means 180, so that the semi-folding fabric 11A is pulled by the pulling force. As shown in the solid line 11, the deflection member 173 is rotated in an upward direction, and is thus moved toward the bubble removing means 180.

That is, the distal end waiting means 170 is a deflection member 173 is rotated in the downward direction in the state in which the semi-folding fabric 11A is temporarily stopped for removing the bubble 11c from the bubble removing means 180, the half-folding The semi-folding fabric 11A, which is conveyed from the means 160, can be temporarily waited, and when the half-folding fabric 11A is transferred from the bubble removing means 180, the deflection member 173 rotates upward. Thus, the half-folding fabric 11A waiting in the far-end temporary waiting means 170 is transferred to the bubble removing means 180 direction.

Therefore, the distal end waiting means 170 is haptic end 11 is continuously conveyed to the half folding means 160 even if the half folded fabric 11A is temporarily suspended for removing the bubble (11c) from the bubble removing means 180 It is to serve to allow the transfer of the continuity without being stopped and at the same time the semi-folding action of the haptic support 11 in the half folding means 160 is to be made continuously without stopping.

Next, the present invention transfers the half-folding fabric 11A, which is waiting in the far-end temporary waiting means 170, by one stroke section (H) by a pair of stroke section feed rollers 175, and then stops it. A bubble preheating removal process S5 is performed to remove the bubbles 11c of the air cap sheet 11 'in the folded fabric 11A.

The pair of stroke section feed rollers 175 are driven to be rotated by the roller driving means 101 described above so that the anti-folding fabric 11A is transported a certain distance by one stroke section H, and then the rotation is stopped. According to this, the semi-folding fabric 1A is also stopped without being transported, and this rotation and stop are repeatedly performed by a control command of the controller 200. Since such control technology is known, the detailed drawings and descriptions thereof will be described. It will be omitted.

Bubble preheating removal process (S5) of the present invention is made by the bubble removing means 180 as shown in FIG.

The bubble removing unit 180 includes a preheating unit 181 having a moving preheating heater 181b corresponding to an upper portion of the fixed preheating heater 181a fixed to the main body 100, and one stroke from the preheating unit 181. The pressurization part 182 is provided with the fixed pressurized heater 182a and the moving pressurized heater 182b corresponding to the upper part in the section H point.

In addition, the moving preheating heater 181b and the moving pressure heater 182b are configured to move up and down by the lifting means 183 in the up and down directions.

The elevating means 183, when the cam 185 is rotated by the reduction motor 184 power, the horizontal straight rod 186 is moved forward, backward and connected to the L-shaped link (187) connected to the interlocking shaft (186 '). ) Is rotated about the link shaft 187 'so that the vertical straight rod 188 connected to the linkage shaft 187 "is raised and lowered in the vertical direction.

In addition, the vertical straight rod 188 is connected to the movable preheating heater 181b and the connecting member 189 connecting the upper portion of the pressurized heater 182b by the interlocking shaft 188 ', thereby moving the preheating heater 181b. And the moving pressurized heater 182b move up and down at the same time. Reference numeral 189 'denotes a guide member.

In the present invention, when the preheating heater 181b and the pressurizing heater 182b are moved upward, the preheating heater 181b and the first movement of the cam 185 are driven by the elevating means 183. After the pressurized heater 182b is moved to be lowered at the same time, the pressure heater 182b is moved to be lifted again and then is temporarily stopped.

The temporary stop after the cam 185 rotates is performed by the controller 200 controlling the reduction motor 184, and the control is repeated.

Therefore, when the moving preheat heater 181b and the moving pressurized heater 182b are moved up and down at the same time and are in a paused state, the stroke section feed roller 175 is driven so that the half-folding fabric 11A is a single stroke section ( After moving by H), as the driving of the stroke section feed roller 175 is stopped again, the semi-folded fabric 11A is also in a state where the feed is stopped.

And when the half folded fabric 11A is moved by one stroke section (H) and is stopped again, the preheating heater 181b and the pressurizing heater 182b are moved downwards at the same time, and then moved up and down again to be temporarily stopped. In this state, the stroke section feeding roller 175 is driven again, and the half-folding fabric 11A is moved by one stroke section H, and then stopped again.

The length of the first stroke section H is set to be the same length as the width P length of the packaging bags 10 and 10 'shown in Figs.

Therefore, the present invention may be able to adjust the spacing of the preheating unit 181 and the pressing unit 182, and the configuration for adjusting such spacing is already well known in the art, so the detailed drawings and descriptions thereof will be omitted. do.

15, the semi-folding fabric 11A is preheated by receiving heat energy while being pressed by the fixed preheating heater 181a and the mobile preheating heater 181b of the preheating unit 181.

At this time, if the polyethylene resin is typically melted at about 130 ° C. or more, the preheating temperature at which the half-folding fabric 11A is preheated by the preheating unit 181 is lower than that of the air cap sheet (90-100 ° C.). The bubble paper 11a of 11 ') is preheated so as to become sultry, and when the bubble paper 11a is preheated, the bubble paper 11a becomes weak in resistance.

In addition, the preheated portion as described above is to be preheated while being slightly pressed as in the virtual line state in FIG.

 Therefore, the present invention is completely powerful while receiving the heat energy by the fixed pressure heater 182a and the moving pressure heater 182b of the pressurizing unit 182 in the stopped state after moving the preheated portion by one stroke section (H). As it is in a pressurized state, it becomes the pressed part 14a of a fully pressurized state, as shown by the solid line of FIG.

At this time, the pressure is applied to the semi-folding fabric (11A) while being pressed by the pressurizing unit 182 also becomes a heating temperature of 90-100 ℃ by allowing the bubble paper (11a) to be pressed while receiving more heat, the tissue becomes flexible The bubble paper 11a, which is extremely weak in resistance, is broken in a torn state and is flat.

In order to facilitate understanding of the present invention, the bubble 11c of the conventional air cap sheet 11 'is made of a bubble paper 11a which is relatively weak enough to be broken even by a pressing force with a finger, such a bubble paper 11c. In the present invention, since the preheating is primarily performed and the secondary is heated again, the pressurizing force is applied with a strong pressing force, so that the bubble 11c is more reliably and quickly torn, and the bubble 11c is broken and the flat portion 14a is flat. To be.

In the pressing unit 14a, the pressing unit 14a is merely pressed in a flat state, but is not bonded to each other.

Next, the present invention is a high frequency fusion and cutting simultaneous process (S6) in the state in which the pressing portion (14a) formed as described above is stopped after the one stroke section (H) is transferred by the drive of the stroke section feed roller (175). This is carried out.

The high frequency fusion and cutting simultaneous process (S6), as shown in Figure 17 and 18, the high-frequency emitter 192 along the fixed guide bar 191 is to move linearly on the high-frequency reaction member 192 ', The high frequency emitter 192 is fixed to a timing belt 195 rotating between a drive timing gear 194 and a driven timing gear 194 'driven by the power of the forward and reverse deceleration motor 193, thereby enabling reciprocating movement. It is made by the high-frequency fusion combined cutting means 190.

The high frequency emitter 192 is provided with a high frequency emitter tip 192a so that the high frequency is emitted toward the high frequency reaction member 192 '. Since the high frequency emitter 192 is a known component, the detailed drawings and description thereof will be omitted. Shall be.

In order to reciprocate the high-frequency generator 191, the forward / reverse motor 193, the driving and driven timing gears 194 and 194 ', and the timing belt 195 are not necessarily used. Mobility means can also be employed.

Referring to FIG. 17, the high frequency emitter 192 receives the high frequency from the high frequency generator 196 whose operation is controlled by the controller 200.

When the high frequency emitter 192 moves from the left to the right direction or from the right to the left direction, the high frequency emitter 192 is respectively sensed by the position detecting sensors 197 and 197 'provided at both sides, and sends an application signal to the control unit 200. ) Is a state in which the movement of the high frequency emitter 192 is stopped by controlling the stationary deceleration motor 193 to be stopped. However, the present invention does not necessarily control the movement of the high frequency emitter 192 only by the above-described sensing means, but other movement control means may be employed.

Therefore, in the present invention, as the high-frequency emitter 192 moves from the upper portion of the pressing portion 14a formed on the half-folding fabric 11A, and emits a high frequency wave, the middle portion of the pressing portion 14a is cut off while being cut. It melts and adheres to a state.

Referring back to FIG. 15, the high frequency emitter 192 is cut and fused at the same time while moving the middle portion illustrated by the dotted line of the depression 14a.

At this time, since the pressed portion 14a is relatively thinner than the thick half-folded fabric 11A, the pressed portion 14a is slightly lifted up on the high frequency reaction member 192 ', thereby making it possible to more surely cut and fusion.

That is, when high frequency radiation is radiated to the pressing portion 14a, high heat is generated, and the pressing portion 14a having a relatively thin thickness is cut. At this time, both edges of the cut portion are instantly melted by high heat. The envelope envelope 11 'and the air cap sheet 11 ", which are pressed and adhered together, are melted together and are fused as shown in FIG. 19, and the fused portion of the envelope 10, 10' is sealed. It becomes the both sides adhesion part 14 and 14 '.

Therefore, in the present invention, since both edges of the cut portion of the pressed portion 14a are melted and melted momentarily by a high temperature, both side bonding portions 14, 14 'of the packaging bags 10, 10' are secure. In addition to being in a state of being firmly bonded, only the edges of the pressed portion 14a of the cut portion are fused, so that both junction portions 14 of the packaging bags 10 and 10 'are shown in FIGS. 2 and 3. 14 ') The width Jb is formed to be relatively narrower than before, thereby providing packaging bags 10 and 10' having a wider packaging space Pb than before.

In addition, the present invention can manufacture the packaging bags (10,10 ') by the 5-6 process, which greatly reduces the number of manufacturing process, thereby increasing production and reducing the depreciation cost, thereby making the packaging bags (10,10') cheaper. ) Will become available.

In addition, the present invention also has the advantage that it is possible to selectively manufacture the packaging bag 10 with the sealing portion 12 and the packaging bag 10 'without it by one manufacturing facility.

While the invention has been shown and described by way of example, it is not limited thereto and may be modified in various forms by those of ordinary skill in the art to which the invention pertains without departing from the scope of the claims. It is self-evident that must be protected.
