The present invention relates to a packaging bag for vegetables, and more particularly, to a packaging bag for vegetables, which facilitates the finishing packaging operation of the fruits and vegetables accommodated in the packaging bag, the manufacturing process of the packaging bag can be made by thermal fusion will be.

In general, in the case of edible crops such as cucumbers, eggplants, and pumpkins, the shape of the crops may be gradually lengthened or bent in the course of growth, as is well known.

Accordingly, the above-mentioned vegetables such as cucumbers, eggplants, and pumpkins were difficult to be standardized. In particular, the fruits and vegetables in the harvesting season are poor in appearance, and thus the value of the products is lowered and the freshness of the crops is reduced. It was influenced.

In addition, the fruits and vegetables are cultivated in a state exposed to the outside during the growth period, there is a risk of being easily harmed from various pests, there was a problem that the commercialization due to the direct pesticide spray on the surface of the vegetables.

As a result, farmers' incomes were reduced, as well as damages to exports.

In addition, in the harvesting season, since the grown vegetables must be separated by size and subjected to separate packing work, there is a problem that the cost incurred in the distribution process increases with the increase of labor costs.

Therefore, in recent years, in cultivating fruit vegetables in order to solve the above problems, it is possible to standardize by allowing the fruit vegetables to grow straight and right in a certain length, and to prevent pesticides from directly reaching and preventing various pests. A crop grower has been developed.

Such a crop planter is formed of a cylinder having a narrow width with respect to the height, and is disclosed as a configuration that completely covers and protects the fruits and vegetables by having the cover installed on both sides rotated around the hinge to open and close the inside.

However, the above conventional crop grower has the following problems.

Conventional crop cultivators have the advantage of being standardized and easy to reuse of vegetables, but the problem of poor workability due to the difficulty of removing the harvested vegetables.

In addition, since a separate packaging operation must be performed after washing the fruits and vegetables removed from the crop grower one by one, such a series of intermediate processing operations are not only time-consuming, but also in terms of cost and manpower.

Of course, a packaging bag made of a film was developed to solve the above problem, but also, due to the manufacturing process by the adhesive such as hot melt, workability and durability is inferior, and finishes the packaging work by using a finishing strap provided separately. Since there is a need to increase the number of work has been a problem that the work convenience of the worker is lowered.

The packaging bag for vegetables uses the film 100 which has a multilayer structure as a base material.

At this time, the film 100 is provided with a different material on one surface and the other surface.

At this time, the packaging bag for vegetables is formed because the one end and the other end of the film 100 provided in the form of cotton is heat-sealed in a state overlapping each other.

That is, due to curling of the film 100 in the form of a surface, a predetermined space portion in which a vegetable may be accommodated is formed therein.

At this time, both ends of the packaging bag for vegetables, as shown in Figures 1 to 4b, is preferably folded in the M shape toward the space.

This is to ensure that the original shape of the fruit is naturally maintained as the fruit is grown inside the bag.

On the other hand, when the direction in which the fruit vegetables grow out of the packaging bag for vegetables, and the other side is called the other side, one side of the vegetable packaging bag is closed by heat fusion, etc., the other side of the vegetable packaging bag It is formed by the opening part G so that it may be lifted.

And, one end and the other end of the overlapped joint portion of the film 100 is further provided with (200) for thermal fusion.

The to (200), serves as a medium so that the same material can be thermally bonded to each other when the heat-sealing of the film 100, it is made of a multi-layer structure.

At this time, the (200) is provided in the longitudinal direction along the joint of the packaging bag for vegetables.

At this time, the heat-sealing surface 210 to the 200 is heat-sealed together with the film 100 is made of the same material as the inner surface 110, which is one surface of the film 100, the heat-sealing surface of the (200) The opposite surface 220 is also made of the same material as the inner surface 110 of the film 100.

On the other hand, the band 300 is further installed in the other portion of the packaging bag for vegetables, close to the opening (G).

The band 300 is to wrap the opening (G) of the packaging bag for vegetables to finish packaging so that the fruits and vegetables accommodated in the inside of the packaging bag for vegetables are not separated.

At this time, the band hole (BH) is preferably formed on the other side of the packaging bag for vegetables.

The band hole (BH) is for the band 300 is passed through to make it easier and more durable packaging of the packaging bag for vegetables.

The band hole (BH) is preferably formed in the form of a plurality of holes penetrating the packaging bag for vegetables.

On the other hand, the band 300 is preferably made of a wire 310 easy to bend, so that the bundle operation of the packaging bag for vegetables is easily made.

At this time, the wire 310 is preferably shielded by the cover member 320, so that it looks neat in appearance.

On the other hand, the band 300 is provided is fixed to the other side of the packaging bag for vegetables by heat fusion, the cover member 320 of the band 300 is made of a material capable of heat fusion to the film 100 of the packaging bag for vegetables.

Hereinafter, the film structure of the packaging bag for vegetables made of the above-described configuration will be described in detail with reference to FIGS. 2A to 4.

First, the inner surface 110 material of one side of the film 100, the base material of the packaging bag for vegetables, is made of polyethylene (PE), and the outer surface material 120 of the other surface of the film is made of polyethylene terep-hthalate (PET). This is preferred.

That is, the film 100, which is the base material for manufacturing the packaging bag for vegetables, is made of a multilayer structure, and the material of the outer surface 120 and the inner surface 110 is made of different materials.

This is for bonding using thermal fusion during the manufacturing process of the packaging bag for vegetables, and to improve the quality.

On the other hand, in order to make a packaging bag for vegetables using the film 100 made as described above, one end and the other end of the film 100 of the surface form is superimposed using a heat sealing sealer (not shown).

Accordingly, a predetermined space is formed inside the film 100.

At this time, one end and the other end of the overlapped film 100, as shown in Figure 2a and 3, one end covers the other end, the inner surface 110 of one end and the outer surface 120 of the other end ) Are in close contact with each other.

At this time, the close contact as described above, it can be seen that the inner surface 110 of the film 100 PE and the outer surface 120 of the film 100 PET.

As described above, it is well known that one end portion and the other end portion of the film 100 cannot be adhered to each other through heat fusion in a state where different materials are in close contact with each other.

On the other hand, in order to heat-bond one end and the other end of the film 100 having a different material as described above is provided with the above (200).

At this time, the (200) is also provided in a multi-layer structure, consisting of a PE layer, PET layer, PE layer from one side of the heat-sealed surface 210 to the middle layer, and the opposite side 220.

At this time, one end portion and the other end portion of the film 100 is overlapped with the heat-sealing surface 210 which is one surface of the to (200) in the space of the packaging bag.

At this time, one end and the other end of the film 100 is the inner surface 110 of the PE material, the heat-sealed surface 210 facing the one end and the other end of the film 100 also becomes the same material PE. .

Accordingly, the to (200) is to be heat-sealed over one end inner surface 110 and the other end inner surface 120 of the film 100.

This is because the heat-sealed surface 210 and the inner surface 110 of the film 100 of the (200) are all made of the same material PE is heat fusion possible.

As a result, one end and the other end of the film 100 are joined to form an encapsulation having a predetermined space.

On the other hand, the process of the film 100 is heat-sealed in more detail as follows.

First, the inner and outer film 100 of the film 100 to be laminated according to the type of fruit and vegetables such as cucumber, amber, eggplant is selected and laminated by a conventional laminating method, and has a diameter to vary depending on the type of fruit and vegetable Cut to width and put into heat sealing machine (not shown).

At this time, the film 100 is continuously supplied along the guide rod (not shown) of the sealing machine which maintains the predetermined sealing temperature, and the one end and the other end of the film 100 are opened with a predetermined width and overlapped. Fusion.

At this time, the to (200) is also heat-sealed to the overlapping portion of the film 100 while being supplied into the inside of the film 100 during the process of heat-sealing one end and the other end of the film 100.

At this time, the (200) is heat-sealed only to the overlapped portion of the film 100, heat to the inner surface 110 of the film 100 opposite to the opposite surface 220 of the (200) by the interference of the guide rod It will not be fused.

Thereafter, the film 100 passing through the guide rod is cut to a predetermined length, and after cutting, the film 100 is closed to one side of the film 100.

At this time, one side of the film 100 is a direction in which the vegetable grows, so as not to leave the packaging bag in the process of growing the vegetable.

At this time, one side of the film 100 is also closed through thermal fusion as shown in FIG.

At this time, since the inner surface 110 of the film 100 are all made of PE, the contact surfaces closely contacted with each other may be bonded by thermal fusion, and are opposed to the inner surface 110 of the film 100. It can be understood that the opposite surface 220 of the to (200) is also made of PE and thus may be thermally fused to each other.

On the other hand, the band 300 is also heat-sealed and fixed to the outer surface 120 of the film 100.

At this time, the cover member 320 constituting the band 300 should be made of PE material to be heat-sealed to the film 100, the film 100 corresponding to the cover member 320 also the inner surface 110 of PE material Should be)

However, the exposed portion of the film 100 corresponding to the cover member 320 is an outer surface 120 of the film 100 having a PET material, and thus heat fusion with the cover member 320 is impossible.

In order to solve such a problem, the inner surface 110 of the film 100 may be exposed to the outside by folding and wetting one end of the film 100 corresponding to the cover member 320 of the band 300.

At this time, in order to flip one end of the film 100, a jig (JIG: not shown) is provided between one end of the film 100 and the outer surface 120, and as the jig is provided, the band 300 is formed of a film ( In the process of heat fusion to 100) there is an effect of blocking the heat transfer to the inside of the film (100).

That is, since the jig blocks heat transfer in the process of thermally bonding the band 300 to the film 100, the inner surfaces of the film 100 may be thermally fused to each other.

Therefore, as shown in FIG. 3, since the cover member 320 of the PE material and the inner surface 110 of the film 100 are opposed to each other, they may be thermally fused to each other.

As described so far, the packaging bag for vegetables according to the present invention is provided in a state in which the band 300 is heat-sealed near the opening G, thereby improving the workability for the finishing packaging operation for tying the opening G. Being technical features.

In addition, by providing the (200) having the same material as the inner surface 110 of the film 100, the heat-sealing process is possible in the manufacturing for the packaging bag for vegetables can be improved quality of the packaging bag for vegetables There are technical features.

In other words, because the manufacturing is not by the manufacturing process by the adhesive but by thermal fusion, the durability of the packaging bag for vegetables can be improved.
