Description

Technical Field

[0001] This invention relates to crystal label transfer stickers, and in particular to a method for manufacturing crystal label hot stamping transfer stickers and the sticker structure thereof. Background Technology

[0002] Crystal label transfer stickers are made by transferring paper that can be applied to objects. A release film is provided on the transfer paper, and the pattern is printed on the release film. The sticker is then transferred and applied to the surface of the object. Known transfer methods for crystal label transfer stickers include labeling, solvent-based transfer labeling, pressure-sensitive transfer labeling, and heat-sensitive transfer labeling. Pressure-sensitive transfer labeling includes direct injection adhesive technology and AB film technology in its manufacturing process.

[0003] The direct-spray pressure transfer labeling process involves first spraying adhesive onto a substrate to form an adhesive layer the same size as the pattern, then printing the desired pattern onto the substrate, and finally covering the pattern and substrate with a film to complete the label production. When using the label, the substrate is removed, the film and pattern are attached to the item and pressed evenly on the pattern surface, and then the film is peeled off to transfer the pattern onto the item.

[0004] However, direct-jet pressure transfer marking and AB film pressure transfer marking cannot transfer fine lines and individual hot stamping patterns. In particular, the adhesive used for direct-jet pressure transfer marking is a semi-cured adhesive that is cured by UV light. The adhesive is not very sticky, and its viscosity will decrease due to environmental and time factors. Therefore, if the adhesive is too sticky, when peeling off the film during the transfer process, the small area of ​​the fine lines and individual patterns means that the adhesive force provided by the adhesive is less than the adhesive's stickiness, making it easy to peel off the film along with the pattern, resulting in the inability to transfer.

[0005] In addition, when applying direct-to-garment pressure transfer printing to fine lines and independent patterns, the small area of ​​the pattern can easily lead to glue overflow. When hot stamping is required, the temperature and pressure of the hot stamping roller can cause glue overflow during the rolling process, which can melt and mix the pattern with the glue, resulting in a blurred pattern.

[0006] AB film pressure transfer labeling involves printing the desired pattern onto release paper with its own adhesive, and finally covering the pattern and substrate with an adhesive film to complete the label production. However, due to the self-adhesive, it is impossible to perform roll hot stamping, and it is also impossible to achieve a hot stamping effect on fine lines and individual patterns.

[0007] Furthermore, if you want to achieve the hot stamping effect by using AB film pressure transfer printing, you need to use a waste removal film method. After printing the pattern on the release paper with its own adhesive, cover it with a thin film, and then peel off the film to separate the adhesive outside the pattern from the release paper, so that the adhesive on the release paper can be removed, and then hot stamping can be performed.

[0008] However, when the pattern consists of fine lines and independent graphic text, the very narrow spacing between them means that the film adheres only partially, not completely, to the gaps. Therefore, when the film is peeled off, not all the adhesive in the gaps is removed, leaving residue around the graphic text. If this residue comes into contact with the printing process, it can cause the pattern to melt and mix with the adhesive, resulting in a blurred image. Furthermore, when the film is peeled off, the fine lines and independent patterns are easily torn along with the film due to insufficient adhesion, causing damage. Additionally, during the transfer process to the printed object, when the film is peeled off, the contact between the film and residual adhesive causes them to pull and tear, damaging the surface of the pattern and hindering the improvement of yield.

[0009] In conclusion, the known crystal embossed transfer logo, when rolled with a hot stamping layer to give the product a metallic texture, is only suitable for large-area or connected lines of stickers, and cannot enhance the product's sophistication or bring about a breakthrough.

[0010] Therefore, how to solve the above problems is the primary issue that this invention aims to address. Summary of the Invention

[0011] The main objective of this invention is to provide a sticker manufacturing method and a sticker structure that enhances the sophistication of the product.

[0012] To achieve the above objectives, the present invention provides a sticker manufacturing method, comprising the following steps:

[0013] a: A printed layer and a hot stamping layer are sequentially sprayed onto a release substrate to form a hot stamping layer, and a coating layer is applied to the hot stamping layer and the release substrate not covered by the hot stamping layer, and the coating layer is cured.

[0014] b: One side of a film has an adhesive layer, which is applied to the coating layer and then peeled off to separate the coating layer and the hot stamping layer from the release substrate, so as to transfer the coating layer and the hot stamping layer onto the film.

[0015] c: The coated layer and the hot stamping layer are respectively attached to an adhesive layer on a release paper on the side away from the film to make the sticker.

[0016] Preferably, the hot stamping layer is detachably disposed on the release substrate and is pseudo-attached to the coating layer, the hot stamping layer having a surrounding edge bound by the coating layer and a cover surface covered by the coating layer.

[0017] Preferably, a white base layer and a color layer are sequentially printed and stacked on the release substrate to form the printed layer.

[0018] Preferably, the hot stamping layer contains a varnish component.

[0019] Preferably, the hot stamping layer is partially or completely applied to the printed layer.

[0020] Preferably, the coating layer is composed of resin.

[0021] Preferably, the hot stamping layer is made of a resin with different properties than the coating layer.

[0022] Preferably, the membrane is in the form of a thin film and is made of OPP, PET, PE or PVC material.

[0023] The beneficial effects of this invention are as follows: by making the hot stamping layer falsely adhere to the coating layer, and by ensuring that the hot stamping layer does not come into contact with the adhesive layer of the film and thus does not pull on each other, the pulling force of the film being torn off can be resisted, so that the fine lines and independent patterns of the hot stamping can be completely transferred onto the item, thereby enhancing the product’s sophistication and bringing a breakthrough to the product.

[0044] Item 6 Detailed Implementation

[0045] First, please refer to Figures 1-10 The sticker manufacturing method provided by the present invention comprises the following steps, wherein:

[0046] Please see Figure 3 First, a printed layer 21 and a hot stamping layer 22 are sequentially sprayed onto a release substrate 10 with release force to form a hot stamping layer 2. Then, a coating layer 3 is applied to the hot stamping layer 2 and the release substrate 10 not covered by the hot stamping layer 2, and the coating layer 3 is cured. The hot stamping layer 2 is separably disposed on the release substrate 10 and is pseudo-attached to the coating layer 3. The hot stamping layer 22 contains varnish to protect the printed layer 21 and produce a glossy finish.

[0047] In this embodiment, a white background layer 211 and a color layer 212 are sequentially printed and stacked on the release substrate 10 to form the printed layer 21. The shape and size of the white background layer 211 are equal to or slightly larger than the shape and size of the color layer 212. The color layer 212 is printed on the white background layer 211 using the principle of CMYK (blue, red, yellow, and black) four-color printing, making the full-color pattern more vivid. Of course, depending on the actual machine settings, the present invention can also sequentially print and stack the color layer 212 and the white background layer 211 on the release substrate 10 to achieve the same purpose of forming the printed layer 21. In addition, in other embodiments, the present invention can also print only the color layer 212 to form the printed layer 21, thereby achieving a semi-transparent full-color effect.

[0048] Please continue reading. Figure 4 , Figure 5Next, one side of a film 4 has an adhesive layer 41. The adhesive layer 41 is used to cover the coating layer 3 and then peeled off, so that the coating layer 3 and the hot stamping layer 2 are separated from the release substrate 10, so as to transfer the coating layer 3 and the hot stamping layer 2 onto the film 4. In this embodiment, the film 4 is in the form of a thin film and is made of OPP, PET, PE or PVC material. It can also have the same function as the film 4 through other materials, which does not limit the present invention.

[0049] Please continue reading. Figure 6 Finally, the coating layer 3 and the hot stamping layer 2 are respectively attached to an adhesive layer 51 on a release paper 5 on the side away from the film 4, thus completing the sticker production of the present invention.

[0050] The stickers manufactured using the sticker manufacturing method provided by this invention have the following structure, such as... Figure 6 As shown, it is mainly composed of release paper 5, printing layer 21, hot stamping layer 22, coating layer 3 and film 4 stacked in sequence. In this embodiment, coating layer 3 is made of resin, while hot stamping layer 2 is made of resin with different properties from coating layer 3, so that the two do not stick to each other. The resin can be UV resin, water-based resin, oil-based resin, acrylic resin or PVB resin.

[0051] Furthermore, please refer to the accompanying materials. Figure 7 , Figure 8 During the manufacturing process, when the resin is applied to the hot stamping layer 2 and the release substrate 10 not covered by the hot stamping layer 2 and cured to form a thin film coating layer 3, the coating layer 3 completely covers the hot stamping layer 2, so that the periphery of the hot stamping layer 2 is bound by the coating layer 3 and has a rim 23, while the upper surface of the hot stamping layer 2 is covered by the coating layer 3 and has a covering surface 24. The binding force generated by the coating layer 3 around the hot stamping layer 2 and the covering force generated on the upper surface of the hot stamping layer 2 form a pseudo-adhesion. Therefore, even resins with different properties can adhere to each other and achieve a bonding effect without the need for adhesive.

[0052] It should be further noted that, in this embodiment, the hot stamping layer 22 can be partially or completely disposed on the printed layer 21, wherein, for example... Figure 9 As shown, the hot stamping layer 22 is partially rolled onto the printed layer 21, so that the printed layer 21 simultaneously has the glossy feel of being hot stamped and the matte feel of not being hot stamped, giving the sticker provided by the present invention a rich and varied design effect.

[0053] Please see Figure 10To illustrate the actual use of the sticker provided by this invention, firstly, the release paper 5 is torn open, allowing the adhesive layer 51 of the release paper 5 to transfer to the hot stamping layer 2 and the coating layer 3 not covered by the hot stamping layer 2. Then, it is applied to the surface of the object 6. The film 4 is pressed evenly to ensure the hot stamping layer 2 is completely adhered to the surface of the object 6. The film 4 is then torn open. At this point, the hot stamping layer 2 forms a bond with the coating layer 3 only through the binding force of the coating layer 3 around its periphery and the covering force of the coating layer 3 covering its circumference. The foil layer 2 exhibits a pseudo-adhesion, and since it does not directly contact the adhesive layer 41 of the film 4, when the film 4 is peeled off, the foil layer 2 and the adhesive layer 41 will not pull against each other, making it easy for the coating layer 3 to separate from the foil layer 2. In other words, when the binding force and covering force exerted by the coating layer 3 on the foil layer 2 are less than the adhesion force exerted by the adhesive layer 51 between the coating layer 51 and the substrate 6, only the coating layer 3 will be peeled off along with the film 4, leaving the foil layer 2 on the substrate 6, thus achieving easy transfer. Even if the foil layer 2 consists of fine lines and independent graphic text, the coating layer 3 and the foil layer 2 can still be easily separated, leaving the foil layer 2 on the substrate 6. In this embodiment, using self-adhesive tape as the release paper 5 of the present invention can achieve an increased adhesion effect.

[0054] It should be noted that this invention does not use adhesive materials as the substrate or directly spray adhesive onto the substrate. Instead, it directly inkjet prints on the release substrate 10 with release force to form a printed layer 21, so that there is no adhesive between the printed layer 21 and the release substrate 10. In this way, when using hot stamping for fine lines and individual graphics and text, there is no need to worry about excess adhesive or residual adhesive being affected by the temperature and pressure of hot stamping, which would cause the graphics and text to become blurred or damaged. This effectively achieves the function of hot stamping for fine lines and individual graphics and text, thereby improving the quality and refinement of the product.

[0055] In summary, the sticker manufacturing method and sticker structure provided by this invention have the following technological advancements and advantages:

[0056] 1. Through the binding force generated by the coating layer 3 around the hot stamping layer 2 and the covering force generated on the circumference of the hot stamping layer 2, the hot stamping layer 2 is pseudo-adhered to the coating layer 3. The hot stamping layer 2 does not directly contact the adhesive layer 41 of the film 4. Therefore, when the film 4 is peeled off, the coating layer 3 and the hot stamping layer 2 can be easily separated, avoiding the hot stamping layer 2 being torn off together. This allows the fine lines and independent graphics and text or patterns with textured surfaces that have been hot stamped to be completely transferred to the substrate 6, thereby improving the quality of the product.

[0057] 2. By directly inkjet printing on the release substrate 10 with release force to form a printed layer 21, there is no adhesive between the printed layer 21 and the release substrate 10. Therefore, when using hot stamping for fine lines and individual graphics and text, there is no need to worry about excess or residual adhesive being affected by the temperature and pressure of hot stamping, which could cause the graphics and text to become blurred or damaged. This method can effectively hot stamp for fine lines and individual graphics and text.

[0058] The above embodiments are disclosed only to illustrate the present invention and are not intended to limit the present invention. Therefore, any changes in values ​​or substitutions of equivalent components should still fall within the scope of the present invention.

[0059] In conclusion, since this invention can clearly demonstrate to those skilled in the art that it can achieve the aforementioned objectives, it complies with the provisions of the Patent Law, and therefore an application is filed in accordance with the law.
