Air Packaging Bag and Air Packaging Bag Forming Machine For Molding Them

The present invention relates to an air packaging bag and an air packaging bag molding machine, and more particularly, to an air packaging bag and an air packaging bag molding machine for protecting a product which may be damaged from an external impact.

In general, expensive home appliances such as laptops and TVs are usually stored in an outer packaging box and packaged in an outer packaging box to protect them from falls and external shocks that may occur during transportation. to be. In the above, the inner packaging container is generally manufactured by using the same or similar to the outer shape of the target product to be packaged using styrofoam to prevent the product from shaking. In recent years, in order to protect the environment, in the case of small packaging products such as paper packaging containers or video or portable cassettes that can be easily disassembled, they are internally packed using air caps.

However, such an inner packaging container has the following problems.

First, products such as large TVs, computers, and monitors use Styrofoam to make internal packaging containers. In this way, the inner packaging container using styrofoam has to produce a packaging container manufacturing mold for each product in order to have an internal shape similar to the product to be packed, which is very complicated, takes a long time, and generates a high cost. In addition, there is a problem in that the mold must be prepared for each product to be packaged.

Second, internal packaging containers made of styrofoam are not available for mass loading at the production site. In other words, in a narrow production site, a large packaging container has a problem that is very difficult to handle. Styrofoam's internal packaging containers take up a lot of volume and cannot be loaded in large quantities at the place of use, so they must be taken from a separate storage area such as a warehouse. There is this.

Third, in order to solve the above problems, an inner packaging container formed of paper has recently been used. Product packaging containers made of these papers are cumbersome to be manufactured using a separate mold, but can be stacked and stacked when using the packaging containers in the field of use, so that the loading space can be used efficiently and formed by using paper. However, the empty space is generated between the inner container and the outer box, and due to such a space, the product is not completely protected, such as impact or shaking.

Fourth, in case of small products such as mobile phones or MP3 players, the products can be protected from impact by packing the products using air caps and storing them in an outer box, but the products are broken due to the weak air storage room of large air caps. As such, the packaging method as described above is not used.

The present invention has been proposed in order to solve the above-mentioned problems, and an object of the present invention is to provide an air packaging bag including a unit cell in which a cushion layer is formed by injecting a fluid, compared to a conventional packaging material injecting only air. It is possible to inject fluids such as gels so that the low temperature state provides an air packaging bag for the goods to be transported.

In addition, the present invention is a unit cell (except the unit cell located at the bottom) to facilitate the injection of fluid containing air even when the air inflow is not smooth due to crushing of the air inlet path, which is a disadvantage of the conventional air injection packaging material The application of the release material to the upper and lower ends of the fluid injection path is formed, connected to the fluid injection path to provide an air packaging bag formed a structural chamber that is a path for the fluid to move.

In addition, the present invention has been made in consideration of the above circumstances, and an object of the present invention is to facilitate the loading and handling of the inner packaging container in the product production line and to allow the loading of a large quantity of packaging containers in the product production line. The present invention provides an air bag molding machine that can improve quality and reduce defects in a packaging process.

In addition, for another object of the present invention by folding the matized air packaging bag in the form of a packaged product to use in the form of a bag to reduce the cost used in the production of the inner packaging container without the need for a mold for each product The present invention provides an air bag molding machine that can be easily transformed into various forms.

In addition, another embodiment of the present invention is to provide an air packaging bag molding machine that can be easily transformed into various forms such as an ice pack by injecting a refrigerant other than air into the air chamber.

Referring to the principle of the nozzle of the cell used in the air packaging bag of the present invention with reference to the bar shown in Figure 1, first, the first to fourth films are laminated in order to unite, the second film and the third The fluid introduced between the films is introduced between the first film and the second film through the air hole perforated in the second film, the fluid introduced between the first film and the second film inflates the unit cell, the first film Inflow of fluid between the second film and the second film is increased, and as the cell swells, the flow path formed between the second film and the third film is reversed.

Through this process, the fluid is eventually filled between the first film and the second film and swells, so that the cell functions as a cushion as a whole, and the flow path formed between the second film and the third film is blocked by the swelling pressure. In other words, it serves as a nozzle.

Next, the manufacturing method of the air packaging bag using the principle of the nozzle of the unit cell used in the air packaging bag described above.

In the manufacturing method of the air packaging bag of this invention, a mold release material is apply | coated to the predetermined part of the upper surface of a 3rd film first. Next, a second film having air holes is placed on the predetermined part of the third film to which the release material is applied and overlapped. Next, the fourth film is positioned on the lower surface of the third film in a state where the second and third films are overlapped, and then the outer contour to form the structural chamber is thermally fused. In the next process, the first outer film is placed on the upper surface of the second film, and heat-sealed to the outer boundary of the outer boundary of the unit cell.

Through the above process, the air packaging bag is combined with the film by heat fusion except for the first passageway to which the release material is applied and the outer boundary line forming the structural chamber inside the cell, and the release material is located at the bottom of the air packaging bag. Is not applied. This is to prevent the flow of the injected fluid at the bottom of the air bag.

By this operation, the first to fourth films are heat-sealed in the outer boundary area of the first cell based on the unit cell, that is, the space between the unit cell and the unit cell, and forms a structural chamber toward the inside of the unit cell. The outer contour is thermally fused, so that the inner part of the structural chamber is not thermally fused between the second film and the third film coated with the release material and inside the unit cell.

Next, the process of injecting fluid into the air bag will be described.

When the fluid is forcedly injected through the passage formed between the second film and the third film at the upper end of the air packaging bag, the fluid is introduced into the cell through the passage through which the release material is applied and the flow path is secured. The fluid is filled from the cell formed at the bottom end via each unit cell through another passage formed at the bottom end of the cell via each unit cell.

Looking at the aspect of the fluid filling in each unit cell, the fluid is gradually inflated as it enters between the first film and the second film through the air hole perforated in the second film, and thus between the first film and the second film As the cell swells due to the introduced fluid, the fluid presses the second film and the third film, thereby blocking the fluid entry into the cell. Therefore, the fluid introduced through the first passage is sequentially filled into the cells in the upward direction starting from the cell formed at the bottom of the air packaging bag.

In the air packaging bag manufactured as described above, in the air packaging bag, a release film is applied to an upper end portion, and a third film and a perforated air hole are formed by incorporating the second film, and the second film and the second film to serve as nozzles. And a flow path formed between the third film and the first film formed on the upper surface of the second film and the fourth film formed on the lower end of the third film and the second to fourth films simultaneously. It is configured to include a unit cell which is formed by the heat fusion at the same time to the structure chamber and the first to fourth film formed.
