Description
Technical Field
[0001] The utility model belongs to the technical field of anti-counterfeiting packaging, and in particular relates to anti-counterfeiting electroplated aluminum with three-dimensional spherical dandelion holographic features. Background Art
[0002] Holographic anodized aluminum is a material widely used in anti-counterfeiting packaging technology. Its principle is based on the interference and diffraction of light, creating dynamic and three-dimensional holographic images on the film, thereby achieving anti-counterfeiting effects. Holographic anodized aluminum has a wide range of applications. It can be hot-stamped on a variety of materials such as cardboard, plastic, and metal at appropriate temperature and pressure. It not only plays an anti-counterfeiting role, but also adds decorative effects to the product. Combined with digital printing technology, holographic anodized aluminum is more helpful for manufacturers to conduct marketing, award distribution, and control product flow.
[0003] However, conventional holographic anodized aluminum also faces some challenges in practical applications. The main problem is that conventional holographic anodized aluminum used on high-end products is easy to be counterfeited. Since the manufacturing process is relatively simple and the interference conditions of the hologram are regular, some lawless elements can produce counterfeit and inferior products by copying the holographic film, which poses a huge threat to anti-counterfeiting packaging and has an adverse impact on the healthy development of the market.
[0004] Therefore, the market is in urgent need of a new type of holographic anodized aluminum packaging material, which not only has the traceability function of conventional digital anodized aluminum, but also can effectively solve the problem that the characteristics of conventional holographic anodized aluminum are easy to be counterfeited. The emergence of this material will greatly enhance the effect of anti-counterfeiting packaging, protect the rights and interests of consumers, and promote healthy competition in the market. Utility Model Content
[0005] In view of the above deficiencies in the prior art, the purpose of the utility model is to provide an anti-counterfeiting electroplated aluminum with a three-dimensional spherical dandelion holographic feature. The three-dimensional spherical dandelion holographic feature has a unique effect and a strong three-dimensional sense. It is difficult for peers to imitate and can overcome the shortcoming that holographic electroplated aluminum in the prior art is easily imitated. At the same time, the three-dimensional spherical dandelion holographic feature is combined with digital printing, a QR code is printed on the electroplated aluminum, and after it is hot-stamped on the product outer packaging, not only can the product be given the function of traceability, anti-counterfeiting and award marketing, but its unique holographic characteristics make the product difficult to imitate, thereby improving the safety and credibility of the product.
[0006] The utility model is realized by adopting the following technical solutions:
[0007] The anti-counterfeiting electroplated aluminum with three-dimensional spherical dandelion holographic features includes a substrate layer, a release layer, a holographic coating layer, a coating layer and a hot-melt adhesive layer stacked in sequence from top to bottom; a partially covered molded microstructure layer and a variable data printing layer are arranged in sequence between the holographic coating layer and the coating layer.
[0008] The substrate layer is a PET film with a thickness of 10 to 20 μm.
[0009] The release layer is water-based wax, and the dry coating amount is 1-2 g / m 2 .
[0010] The embossed microstructure layer is formed by embossing a nickel plate with a three-dimensional spherical dandelion microstructure on a substrate layer coated with a release layer and a holographic coating layer, and copying the three-dimensional microstructure on the nickel plate onto the holographic coating layer.
[0011] The three-dimensional spherical dandelion holographic microstructure is generated by a light source, a diffractive optical element, and a lens element. The light source generates diffraction light waves in multiple directions and angles after passing through the diffractive optical element. The diffraction light waves are focused by a lens to generate a three-dimensional spherical dandelion holographic microstructure on a photosensitive material. After reprinting and plated, a nickel plate with a three-dimensional spherical dandelion microstructure is obtained.
[0012] The molded microstructure layer includes three-dimensional spherical dandelion holographic features.
[0013] The central part of the three-dimensional spherical dandelion holographic feature is granular, the edge part is fluffy and composed of fine lines, and the transition part is ciliary, wherein the fluffy fine lines are in "clusters" and numerous clusters constitute a fluff collection.
[0014] The three-dimensional spherical dandelion holographic features are distributed symmetrically around the center.
[0015] The variable data printing layer is formed by printing using a contact digital printer or an inkjet non-contact printer.
[0016] There is at least 1 mm of blank area between the variable data printing layer and the embossed microstructure layer, and the embossed microstructure layer does not affect the scanning pass rate of the two-dimensional code on the variable data printing layer.
[0017] The coating layer is an aluminum coating layer or a zinc sulfide coating layer. Preferably, the coating layer is an aluminum coating layer. The aluminum coating layer has the function of reflecting light, so that the hot stamping pattern has a metallic luster.
[0018] By using a nickel plate with a three-dimensional spherical dandelion microstructure, a molded microstructure layer is obtained on the substrate layer coated with a release layer and a holographic coating layer, and then a coating layer is obtained through a coating process, and then an aluminum washing process is further introduced to wash the area that does not need aluminum coating to obtain a transparent hollow aluminum washing area. The three-dimensional spherical dandelion holographic feature retains part of the holographic structure after aluminum washing, and the three-dimensional spherical dandelion holographic feature is more concealed, which increases the difficulty for counterfeiters to imitate. The holographic feature can be used as an important feature for manufacturers to judge the authenticity.
[0019] The hot melt adhesive layer is hot melt adhesive, and the dry coating amount is 1-2 g / m 2 The function of hot melt adhesive is to stick the hot stamping pattern to the hot area of the product.
[0020] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0021] The anti-counterfeiting electroplated aluminum with three-dimensional spherical dandelion holographic features described in the utility model effectively avoids the problem that the interference fringes of common holograms on the market are highly regular and are easy for professionals to imitate conventional holograms by introducing three-dimensional spherical dandelion holographic features with strong randomness of interference fringes and difficult to imitate, and has the characteristic of anti-copying; at the same time, the three-dimensional spherical dandelion holographic microstructure pattern after aluminum washing can be used as a hidden identification anti-counterfeiting feature; the three-dimensional spherical dandelion holographic feature is combined with digital printing, a two-dimensional code is printed on the electroplated aluminum, and after it is hot-stamped on the outer packaging of the product, not only can the product be given the functions of traceability, anti-counterfeiting and award-giving marketing, but its unique holographic characteristics make the product difficult to imitate, thereby improving the safety and credibility of the product.
