Description

A label, a method for manufacturing the same, and a method for displaying information on a substrate using the same

[0001] The present invention relates to a label and a method of fixing such a label to a substrate to display information of the substrate.

[0002] Generally, information including the history of the product is displayed on the substrate. This information varies depending on the type of substrate, but in the case of a substrate such as a tire, it is typically formed by attaching a label. Conventional labels have ink printed on their surface by a heat transfer method and are attached to the surface of the tire, for example, the bead, to display product information.

[0003] However, conventional labels such as the above frequently detach and fall off due to external forces applied continuously and repeatedly after being attached to a substrate, and especially as the ink is erased by friction, the printed information is lost. Consequently, a situation arises where product information cannot be recognized.

[0004] The purpose of the present invention is to propose a label that allows information on a substrate, such as a tire, to be maintained for a long period of time by ensuring that the displayed information is not easily lost, a method for manufacturing the same, and a method for displaying information on a substrate using the same.

[0005] The present invention proposes a label comprising a colored primer layer, an aluminum deposition layer, and a film layer that are sequentially stacked, wherein the aluminum deposition layer is formed such that information of the substrate is perforated into letters or patterns, thereby exposing the colored primer layer according to the letters or patterns, and the colored primer layer is filled into the letters or patterns by heat and pressure so that the information is displayed in a state that is not easily erased; and a method for manufacturing a label by displaying information on the aluminum deposition layer using a laser, and further proposes a method for displaying information on the substrate by fixing the label to the substrate using heat and pressure to achieve the above objective.

[0006] According to the present invention, a label is obtained in which information of a substrate is clearly displayed, and when the label is attached to a substrate by applying heat and pressure, the displayed information is not easily erased while maintaining a firmly attached state, thereby enabling the information of the substrate to be displayed for a long period of time.

[0011] FIG. 5 is an exemplary diagram showing a method of displaying information on a substrate by attaching a label according to the present invention to the substrate.

[0012] The present invention proposes a label comprising a colored primer layer, an aluminum deposition layer, and a film layer that are sequentially stacked, wherein the aluminum deposition layer is formed such that information of the substrate is perforated into letters or patterns, thereby exposing the colored primer layer according to the letters or patterns, and the colored primer layer fills the letters or patterns by heat and pressure, so that the information is displayed in a state that is not easily erased.

[0013] A method for manufacturing a label is proposed, wherein a label is formed in a structure in which a colored primer layer, an aluminum deposition layer, and a film layer are sequentially laminated, and a laser is irradiated onto the aluminum deposition layer so that the laser passes through the film layer and burns information of the substrate in the form of letters or patterns onto the aluminum deposition layer, wherein the letters or patterns are formed by perforating the aluminum deposition layer so that the colored primer layer is exposed according to the letters or patterns perforated in the aluminum deposition layer, thereby displaying information.

[0014] A method for displaying information on a substrate is proposed, comprising a colored primer layer, an aluminum deposition layer, and a film layer that are sequentially stacked, wherein the aluminum deposition layer is provided with a label sheet having letters or patterns of information of the substrate formed by perforation therein, and the label sheet is placed against the substrate, and then heat and pressure are applied over the label sheet toward the substrate so that the colored primer layer melts due to the heat and pressure and fills the perforated letters or patterns and fuses to the film layer, and additionally, the colored primer layer melted due to the heat and pressure fuses to the substrate and fixes, thereby allowing the information to be displayed on the substrate while being protected by the film layer.

[0015] Hereinafter, the present invention will be described with reference to the attached drawings, FIGS. 1 to 5, with reference to preferred embodiments.

[0016] FIG. 1 is an illustrative diagram showing the basic configuration of a label according to the present invention, and FIG. 2 is an illustrative diagram showing another embodiment of a label according to the present invention.

[0017] As described above, the label according to the present invention includes a label sheet (100).

[0018] The label (100) displays information about the substrate and can be formed by including a colored primer layer (130), an aluminum deposition layer (150), and a film layer (170). It is a structure in which the aluminum deposition layer (150) and the film layer (170) are formed on the colored primer layer (130). In addition to this basic configuration, the label (100) may have an adhesive layer (110) formed below the colored primer layer (130) and a coating layer (190) formed on the film layer (170).

[0019] The colored primer layer (130) may be formed in black. It is preferable that this colored primer layer (130) be formed from a material that melts when heated to a certain degree and hardens to a certain degree when cooled. For example, it may be formed from a polyolefin-based material.

[0020] The aluminum deposition layer (150) is a layer formed by depositing aluminum, and information of the substrate is formed by perforating it. The information of the substrate is formed by perforating it in the form of letters or patterns, for example, a barcode containing numbers or other information representing the serial number of the substrate is formed. Here, a method of burning by irradiating with a laser may be adopted as a method for perforating the letters or patterns.

[0021] The film layer (170) can be formed from a thin film made of PET (polyethylene terephthalate) or PI (polyimide). It is formed to be transparent or semi-transparent so as to transmit light, thereby allowing the letters or patterns formed on the aluminum deposition layer to be visually revealed.

[0022] The adhesive layer (110) is formed of an adhesive material and serves to temporarily fix the position of the label (100) by adhering it to the substrate. A release liner (200) may be laminated under this adhesive layer (110), and the release liner (200) is removed when using the label according to the present invention.

[0023] Meanwhile, the adhesive layer (110) can be formed using either an adhesive or an adhesive.

[0024] The coating layer (190) serves to cover and protect the film layer (170), thereby protecting the information formed on the aluminum deposition layer (150). It is preferable that this coating layer (190) be formed from a material having heat resistance, and it may be formed from an acrylic copolymer.

[0025] It is preferable that the coating layer (190) be formed with a matte finish. If the coating layer (190) is formed with a matte finish, it helps to prevent diffuse reflection of light when scanning information displayed on the label according to the present invention with a scanner, thereby enabling the information to be read accurately. Additionally, the coating layer (190) may be formed with a colored finish. For example, if the colored primer layer (130) is formed in black, it is possible to form it with a color such as yellow, which is a contrasting color.

[0026] Meanwhile, in the label paper (100) described above, it is preferable that the colored primer layer (130) be formed with a thickness of 5 to 50 μm, the aluminum deposition layer (150) with a thickness of 0.5 to 3 μm, and the film layer (170) with a thickness of 50 to 200 μm. Also, it is preferable that the adhesive layer (110) be formed with a thickness of 5 to 25 μm and the coating layer (190) with a thickness of 1 to 5 μm.

[0027] If the thickness of the colored primer layer (130) is thinner than the above range, sufficient adhesion is not obtained even when heat and pressure are applied to the substrate, and the perforated letters or patterns are not sufficiently filled, and if it is thick, the overall thickness of the label paper (100) becomes excessively thick, so it is desirable to determine it within the above range.

[0028] If the thickness of the aluminum deposition layer (150) is thinner than the above range, the letters or patterns formed by perforation will not be clear, and if it is thick, it may cause difficulties in the process of perforating the letters or patterns and may also become a factor that interferes with the process of attaching the label paper (100) to the substrate, so it is desirable to determine it within the above range.

[0029] If the thickness of the film layer (170) is thinner than the above range, wrinkles may occur during the process of attaching it to the substrate by applying heat and pressure, and if it is thicker, the total thickness of the label (100) becomes excessively thick, so it is desirable to determine it within the above range.

[0030] If the thickness of the adhesive layer (110) is thinner than the above range, the adhesive force is not sufficiently exerted, and if it is thick, the processability decreases and the defect rate increases, so it is desirable to determine it within the above range.

[0031] If the thickness of the coating layer (190) is thinner than the above range, the protective effect on the letters or patterns marked on the aluminum deposition layer (150) is insufficient, and if it is thicker, the overall thickness of the label (100) becomes excessively thick, so it is desirable to determine it within the above range.

[0032] In the label according to the present invention formed as described above, the letters or patterns formed on the aluminum deposition layer (150) are visually revealed by passing through the film layer (170). Similarly, when the coating layer (190) is formed, the letters or patterns are visually revealed by passing through the film layer (170) and the coating layer (190). Therefore, by displaying the information of the object on the label sheet (100) as letters or patterns and attaching it to the object, the information of the object can be displayed.

[0033] FIG. 3 is a flowchart showing the process of manufacturing a label according to the present invention, and FIG. 4 is an example diagram showing a method of displaying information on a label according to the present invention. FIG. 3 and FIG. 4 show the process of manufacturing a label in which an adhesive layer (110), a coating layer (190), and a release liner (200) are all formed.

[0034] As described above, the label according to the present invention is formed with a label sheet (100) having a structure in which a colored primer layer (130), an aluminum deposition layer (150), and a film layer (170) are sequentially laminated, and the label sheet (100) may additionally have an adhesive layer (110) and a coating layer (190) formed therein. The label sheet (100) formed in this manner is formed as a label according to the present invention by laminating a release liner (200) onto the adhesive layer (110).

[0035] The process of forming the label (100) as described above consists of forming a film layer (170) with a transparent PET or PI film, forming a coating layer (190) on one side of the film layer (170), forming an aluminum deposition layer (150) by depositing aluminum on the other side of the film layer (170), and sequentially applying a material to form a colored primer layer (130) and an adhesive layer (110) on the aluminum deposition layer (150).

[0036] Meanwhile, the label according to the present invention displays information of the substrate in the form of letters or patterns on the aluminum deposition layer (150). At this time, the laser is irradiated onto the aluminum deposition layer (150) on the film layer (170) to display information of the substrate (300) in the form of letters or patterns. Then, the laser is irradiated onto the aluminum deposition layer (150) on the coating layer (190) on which the coating layer (190) is formed to display information of the substrate (300) in the form of letters or patterns.

[0037] As described above, when a film layer (170) and a coating layer (190) are formed, the laser passing through the coating layer (190) burns the aluminum deposition layer (150) in the shape of a letter or pattern. During this process, the aluminum deposition layer (150) is perforated according to the letter or pattern, and as a result, the colored primer layer (130) is exposed according to the letter or pattern perforated in the aluminum deposition layer (150), thereby visually displaying information.

[0038] FIG. 5 is an exemplary diagram showing a state in which information is displayed on a substrate by attaching a label according to the present invention to the substrate.

[0039] The label (100) described above can be attached to a substrate (300) so that the substrate (300) can display information. At this time, the substrate (300) may be formed of a material that can be melted by heat, for example, rubber, and may be a tire.

[0040] Attachment of the label (100) is achieved by applying heat and pressure. After attaching the label (100) to the point where it is to be attached, heat and pressure are applied from the label (100) toward the substrate (300), which is a so-called vulcanization process. Accordingly, the colored primer layer (130) fuses with the substrate (300) and is firmly fixed. If the substrate (300) is a tire, vulcanization fusion occurs.

[0041] Meanwhile, in the above process, a portion of the colored primer layer (130), which is melted by heat and pressure, is filled into the letters or patterns formed by perforating the aluminum deposition layer (150). At the same time, it is also fused to the film layer (170) formed on the aluminum deposition layer (150). Accordingly, the colored primer layer (130), the aluminum deposition layer (150), and the film layer (170) are integrated by the colored primer layer (130).

[0042] Meanwhile, when the adhesive layer (110) is formed, the adhesive layer (110) melts due to heat and pressure and fuses to the substrate (300). The adhesive layer (110) fuses to the substrate (300) together with the colored primer layer (130) to form an integrated structure.

[0043] As described above, since the label (100) is fused to the substrate (300), the label according to the present invention can be maintained in a firmly fixed state on the substrate (300). Furthermore, during the process of attaching the label (100) to the substrate, each layer constituting the label (100) becomes integrated with one another, thereby providing structural stability. Additionally, while the information is displayed clearly, the information displayed on the aluminum deposition layer (150) is protected by the film layer (170), and if a coating layer (190) is formed, it is also protected by the coating layer (190). Therefore, the information displayed on the label according to the present invention is not easily erased by external stimuli or friction, allowing the information on the substrate (300) to be displayed for a long period of time.
