Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of anti-fake packaging materials, in particular to an anti-fake packaging material and a wine box. BACKGROUND

[0002] In the current diversified packaging materials such as wine boxes, anti-fake packaging materials are generally used to enhance product highlights, reflect product grades and strengthen anti-fake functions. In the field of optical anti-fake packaging materials, the use of microlens arrays to achieve spatial imaging effects is considered as an excellent visual identification anti-fake solution. This solution mainly includes two implementation methods: transmissive spatial imaging and reflective spatial imaging. The transmissive imaging film has a microlens array on its outer surface. Although it can provide unique spatial imaging effects, the surface of the film cannot be subjected to subsequent printing or film coating processes due to the presence of the microlens array, thereby severely limiting its flexibility and range in actual applications. The reflective imaging film has a graphic structure on its outer surface, thus allowing film coating operations and having more extensive application potential. However, the manufacturing process of the reflective imaging film is extremely complex, especially the alignment accuracy between the microlens array and the micrographic array is extremely high. Not only does it lead to an increase in product thickness, but it also significantly reduces the yield of finished products and sharply increases production costs.

[0003] In summary, the existing spatial imaging anti-fake packaging materials based on microlens arrays, whether transmissive or reflective, have their own technical bottlenecks and application limitations. Therefore, there is an urgent need for an anti-fake packaging material that can achieve spatial imaging and optical effects in a single layer, especially for wine packaging materials, in order to achieve design effect diversity, significantly improve anti-fake properties and enhance the overall aesthetics of the product. CONTENT OF THE INVENTION

[0004] To solve the above-mentioned problems, the present application provides an anti-fake packaging material and a wine box.

[0005] The present application provides an anti-fake packaging material, comprising: a printing layer, a substrate layer, an information layer, a protective layer, a reflective layer and a base material layer which are sequentially stacked, wherein the information layer comprises a first optical structure having a target phase distribution and a second optical structure for generating a preset visual effect.

[0006] Optionally, the first optical structure comprises a plurality of imaging units arranged periodically, the imaging units having the target phase distribution formed by the phase distribution on the surface of an initial imaging structure when a target intermediate image formed by a target light field through the initial imaging structure is inversely propagated to the initial imaging structure and the phase distribution of the initial imaging structure is parallel or tangent to the phase distribution.

[0007] Optionally, the initial imaging structure comprises at least one of a microlens, a superlens and a Fresnel lens, and the shape of the imaging unit comprises at least one of a circle, a square, a rectangle and a honeycomb shape.

[0008] Optionally, the second optical structure comprises at least one of a relief structure, a laser structure, a dynamic light and shadow structure, a holographic lens structure, a microlens structure and a superlens.

[0009] Optionally, the anti-fake packaging material further comprises a film coating layer, which is arranged on the side of the printing layer away from the substrate layer.

[0010] Optionally, the anti-fake packaging material further comprises a varnish layer, which is arranged between the printing layer and the substrate layer.

[0011] Optionally, the anti-fake packaging material further comprises a first adhesive layer, which is arranged between the substrate layer and the information layer.

[0012] Optionally, the anti-fake packaging material further comprises a second adhesive layer, which is arranged between the reflective layer and the substrate layer.

[0014] The embodiment of another aspect of the present application also provides a wine box comprising the anti-fake packaging material provided by the foregoing embodiments.

[0015] The first optical structure is a single-layer imaging structure, which avoids the alignment problem of a double-layer imaging structure, reduces the cost, improves the yield, and can be mass-produced. The combination of the first optical structure and the second optical structure enables the information layer to realize the combination of spatial imaging and various optical effects. The protective layer arranged on the information layer prevents the first optical structure and the second optical structure from being copied, and improves the wear resistance and toughness of the packaging material.

[0027] Specifically, the printing layer 1 is a color pattern or text corresponding to the group of text or pattern formed by the first optical structure 31 in the information layer 3, which is printed by a precision intaglio printing machine, and is used to carry visual information such as brand logo and pattern.

In the embodiment, the protective layer 4 is a UV glue layer, and the refractive index of the protective layer 4 is different from that of the information layer 3, so that the structure on the information layer 3 works. If the refractive indices are the same, the structure will be filled.

[0029] Specifically, the reflective layer 5 is a metal layer, which can be an aluminum layer or a metal chromium layer, and can enhance light reflection, improve brightness and imaging effect, which is not limited herein; the thickness of the reflective layer 5 is 10 nm to 40 nm.
