With reference to Figs. 1 to 3, a sachet according to exemplary embodiments of the present invention will be described first. The sachet is a package material for packaging a product that needs to be protected from moisture or oxygen for a long time. The bag essentially comprises two sheets of synthetic resin including a front sheet and a back sheet and has a hole 5 corresponding to a breaking point from an opening position and a cut line 4 in which a plurality of grooves of cutting 40 continuing in a straight line from hole 5 are formed at regular intervals along the opening position.

In the present invention, each of the front and rear sheets has a structure in which a protective layer of the surface 10 is stacked on a base film 25 comprising a reinforcing layer 20 and a layer of heat-sealable resin 30. The protective layer of the surface 10, the reinforcing layer 20, and the heat-sealable resin layer 30 are bonded together with a layer of adhesive interposed therebetween by rolling.

The surface protective layer 10 functions as a barrier to protect the contents of the containers from moisture penetration, oxygen permeation, etc., and the heat-sealable resin layer 30 is to ensure the hygiene of the contents of the container. package. In addition, the reinforcement layer 20 provides properties such as breaking strength, heat resistance, cold resistance, etc., which are necessary for the sachet that serves as the package material and, in particular, ensures easy cutting in a moment in the tear of the sachet starts.

A polyester film (hereinafter referred to as a PET film) having excellent transparency, heat resistance, high tension, dimensional stability, impermeability, moisture resistance, water resistance, chemical resistance, etc., which are suitable For packaging and metallization, it is useful as the protective layer of the surface 10. In addition, a non-oriented film or polyethylene film (PE film), which has a uniform thickness and is a hygienic film widely used as material for flexible packaging , such as food packaging, etc., can be used as a material for the heat-sealable resin layer 30.

For the reinforcement layer 20, which comprises a single nylon material, having excellent heat resistance, cold resistance, and tensile strength and is suitable for providing tear directionality and easy cutting when the sachet is opened, it can be used as in the exemplary embodiment of Figure 2, or of a synthetic film in which a thin aluminum plate is deposited on the nylon surface can be used as in the exemplary embodiment of Figure 3.

When the cutting slots 40 are formed in the front and back sheets comprising the above materials, it is preferred that the slots 40 are formed on the base film 25 formed by the junction of the non-oriented film forming the resin layer. heat sealable 30 to the nylon film or synthetic nylon film forming the reinforcement layer 20. In detail, it is preferred that the cut slots 40 be formed on one side of the reinforcement layer 20 of the base film 25 located in a direction that comes in contact with the protective layer of the surface 10.

The reason for this is that the PET film constituting the protective layer of the surface 10 can be damaged when the surface treatment such as the formation of the cutting grooves 40 is carried out on the completed sheet by joining the layer protective of the surface 10, the reinforcing layer 20, and the heat of the sealable resin layer 30.

In other words, in the case of PET film, silica and alumina are deposited on a film to prevent moisture and oxygen permeation from retaining the contents (mainly food or medication) for a long time. So, when an external pressure, such as voltage, impact, etc. are applied to the PET film, such as during the formation of the cutting slots 40, the film formed of the silica and the alumina is damaged, which reduces the water resistance and barrier performance, thus losing its function as a material of package.

Further, even when the cutting slots 40 are formed in this manner for the above reasons, it is preferred that at least two slots 40 be formed vertically at regular intervals. The reason for this is that when the force acting to break the sachet is somewhat deviated from a slit 40, from which the initial tear begins, during tearing of the sachet, another slit 40 can maintain the shape of cut in a line almost straight. To this end, an appropriate range between the slots 40 is 0.1 to 2 mm.

According to the above described sachet of the present invention, with the formation of the cut line 4, in which the plurality of cutting slots 40 are formed which continue in a straight line at regular intervals along the opening position of the sachet is possible to ensure easy cutting, even when the tearing direction is irregular due to the properties of the base film constituting the sachet, and it is possible to gently cut the sachet along the predetermined straight line of cut 4 at all times during the cut even when the force at a time when the cut begins acts in a deviated direction, as shown in Figure 4.

Next, a method for manufacturing the sachet having the configuration described above in accordance with an exemplary embodiment of the present invention will be described.

As shown in Figure 5, the manufacturing process of the sachet comprises a total of six steps including a step of forming a base film, a step of applying an adhesive onto a surface protective layer and drying the resulting layer, a step of forming a cutting line, a step of bonding the base film and the protective layer of the surface, a step of sealing the large surface sheets, and a step of cutting the sealed sheets of large surface and the formation of a hole.

The first step is to form a base film 25 by bonding a reinforcement layer 20 and a heat sealable resin layer 30. Here, as mentioned above, a nylon material comprising only, which has excellent heat resistance and resistance to cold and is suitable for providing tear directionality and easy cutting when the sachet, or a synthetic film, in which a thin aluminum plate is deposited on the nylon surface, is used for the reinforcement layer 20. In addition, A non-oriented film or polyethylene film, which is very hygienic and widely used as a flexible package material, is used as a material for the heat-sealable resin layer 30.

In the above process, the attachment of the reinforcement layer 20 and the heat-sealable resin layer 30 can be achieved by a lamination process which applies an adhesive to the reinforcement layer 20 or the heat-sealable resin layer. , the resulting layer is dried to form an adhesive layer 15, and passes the reinforcing layer 20 and the heat-sealable resin layer 30, which are facing each other, through a pressure roller, thereby forming a contact between layers. However, any method of joining, which can be joined. Reinforcing layer 20 and the heat-sealable resin layer 30 without damaging the layers, such as the use of a thermal bonding tape, can be used without being limited to a particular method The information on the content (such as the logo, image, recipe, etc.) is printed on the surface of the protective layer of the surface 10 to be unraveled to the base film 25 to form a large surface sheet, and an adhesive is applied to the back side of it. Next, the resulting surface protective layer 10 is dried by hot air in a dry chamber 300.

During the application of the adhesive, it is preferred that the back side of the protective layer of the surface 10 be movable in contact with the surface of an adhesive application roll 204, which is partially exposed to a storage tank 202 of the adhesive, as well as to be applied continuously with the adhesive. In addition, during the drying of the adhesive, it is preferred that the protective layer of the surface 10 be allowed to pass continuously through a chamber 300, which has a 302 inlet and an outlet 304 and in which the hot air blown is of So it dried up.

The next step is to form a cutting line 4 by forming a plurality of straight cutting slots 40 at regular intervals on the base film 25 formed in the previous step. In this process, it is preferred that the cutting slots 40 be formed continuously at the appropriate positions of the base film 25, which will be the opening position of the sachet afterwards, using a shaping device 500 having a structure as shown in FIG. Figs. 7 and 8. Furthermore, an appropriate interval between the cutting slots 40 forming the cutting line 4 is 0.1 to 2 mm.

The base film 25 and the protective layer of the surface 10, which are formed in the previous steps are joined together by a rolling process, forming large-area front and rear sheets. In fig. 6, the reference number 720 indicates a winding roll on which a large front area sheet is rolled, and the reference number 740 indicates a winding roll on which a large surface back sheet is rolled, the sheet back of large surface that are formed in the same process as described above.

The next step is to seal the front area of two large and back sheets in a size suitable for the formation of the sachet. In this process, front and rear large surface sheets 1 and 2 are allowed to be transferred in contact with each other in order to be sealed in a section (corresponding to the inclined line in the enlarged view of Fig. 6) for the formation of the sachet by a typical 800 heat seal.

Finally, the sealed sheets of large surface are cut into the sections and, at the same time, a hole 5 corresponding to a starting break point is formed in the opening position of each sachet, thus completing the straight sachet divided according to the exemplary embodiment of the present invention.
