[0030] refer to Figure 1 ,like Figure 1 As shown, this utility model provides a multi-layer film structure based on glossy paper 2, including a transparent layer, glossy paper 2, adhesive layer 3 and double-adhesive backing paper 4 distributed vertically;
[0031] Double-sided adhesive backing paper 4, which is located at the bottom of the multilayer film structure;
[0032] Adhesive layer 3, which covers the top surface of the double-sided adhesive backing paper 4;
[0033] Glossy paper 2, at least one side of the glossy paper 2 is a glossy layer 21, the side of the glossy paper 2 facing away from the glossy layer 21 is glued to the top of the adhesive layer 3, and the glossy paper 2 and the double-adhesive backing paper 4 coincide in the projection along the vertical direction.
[0034] The transparent layer includes a first transparent film 11 and a second transparent film 12 printed with different anti-counterfeiting marks. The first transparent film 11 and the second transparent film 12 are both adhered to the glossy layer 21, and the anti-counterfeiting marks of the two do not obscure each other. There is an overlapping area between the adjacent parts of the first transparent film 11 and the second transparent film 12. In the overlapping area, the first transparent film 11 and the second transparent film 12 are fixedly connected.
[0035] In this embodiment, by adhesively bonding a first transparent film 11 and a second transparent film 12 to the glossy layer 21 of the glossy paper 2, the original gloss and aesthetics of the glossy paper 2 are not affected. Furthermore, the anti-counterfeiting function is enhanced by the anti-counterfeiting marks on the first transparent film 11 and the second transparent film 12. In addition, since the first transparent film 11 and the second transparent film 12 are fixedly connected, the bonding strength between the first transparent film 11 and the second transparent film 12 and the glossy paper 2 is improved. Moreover, the combined effect of different anti-counterfeiting marks can increase the difficulty of counterfeiting and make it easier for consumers to identify.
[0036] Specifically, the double-sided adhesive backing paper 4 can be a yellow double-sided adhesive backing paper with a basic basis weight of 120 g / m2 and a thickness between 0.1-0.2 mm. Further, the double-sided adhesive backing paper 4 has a thickness of 0.14 mm.
[0037] Preferably, the first transparent film 11 and the second transparent film 12 have different thicknesses to form an uneven surface texture.
[0038] Preferably, such as Figure 2 As shown, the transparent layer also includes a third transparent adhesive film 13 and a fourth transparent adhesive film 14. The first transparent adhesive film 11, the second transparent adhesive film 12, the third transparent adhesive film 13 and the fourth transparent adhesive film 14 are bonded to the glossy layer 21 in pairs, and there are overlapping areas at the adjacent locations. In the overlapping areas, the adjacent transparent adhesive films are fixedly connected. The first transparent adhesive film 11, the second transparent adhesive film 12, the third transparent adhesive film 13 and the fourth transparent adhesive film 14 are printed with different anti-counterfeiting marks, and the anti-counterfeiting marks do not obscure each other.
[0039] In this embodiment, the anti-counterfeiting marks printed on the first transparent film 11, the second transparent film 12, the third transparent film 13 and the fourth transparent film 14 can be patterns, designs, watermarks, numbers, etc., so that the paper is not easy to imitate, counterfeit or alter.
[0040] Specifically, anti-counterfeiting marks can be printed onto transparent film by rotating a printing roller.
[0041] Preferably, the first transparent film 11, the second transparent film 12, the third transparent film 13, and the fourth transparent film 14 have different thicknesses to form an uneven surface texture.
[0042] Preferably, the adjacent transparent films are fixed to each other by hot-pressing and welding.
[0043] Hot-press welding is a mature technology that uses heat and pressure to bond transparent adhesive films. The hot-pressing process parameters are as follows: Temperature: Adjusted according to the type of adhesive film; TPU: 120-150℃; PET: 130-200℃; PI reinforcing film: 170-175℃; Pressure: 3-5 kgf / cm² (for clothing bonding); 10-15 kgf / cm² for metal composites; pressure ≥50 kPa in a vacuum autoclave; Time: 10-30 seconds for thin films (0.1 mm); 40 seconds for thick films (0.3 mm and above); cooling and setting: 5-10 minutes. Hot-press welding ensures high bonding strength between adjacent transparent adhesive films.
[0044] Preferably, to further enhance the adhesive effect, the adhesive layer 3 includes a first adhesive portion and a second adhesive portion, wherein the first adhesive portion and the second adhesive portion are spaced apart from each other and do not interfere with each other.
[0045] Preferably, the first adhesive portion and the second adhesive portion are parallel to each other, and both are wavy or straight.
[0046] Preferably, the thickness of the adhesive layer 3 is between 0.015 mm and 0.025 mm.
[0047] Specifically, adhesive layer 3 is a water-based emulsion type acrylic polymer adhesive layer, and the thickness of adhesive layer 3 is 0.02 mm.
[0048] Preferably, such as Figure 3 As shown, the glossy paper 2 includes a gold-plated layer, a polyester film layer 22, and an aluminum-plated layer 23 distributed vertically. The gold-plated layer is a glossy layer 21, and the aluminum-plated layer 23 is used to adhere to the top of the adhesive layer 3.
[0049] Specifically, the polyester film layer 22 is a biaxially oriented polyester film with a basic basis weight of 32 g / m2 and a thickness between 0.02 and 0.03 mm.
[0050] This invention also provides a packaging box, including a packaging box body and a packaging structure based on glossy paper 2 as described in any of the above embodiments, after the double-sided adhesive backing paper 4 is removed. The packaging structure is bonded to one surface of the packaging box body by the adhesive layer 3.
[0051] In this embodiment, a first transparent adhesive film 11 and a second transparent adhesive film 12 are glued to the glossy layer 21 of the glossy paper 2 bonded to the packaging box. This does not affect the original gloss and aesthetics of the glossy paper 2. Furthermore, the anti-counterfeiting function is enhanced by the anti-counterfeiting marks on the first transparent adhesive film 11 and the second transparent adhesive film 12. In addition, since the first transparent adhesive film 11 and the second transparent adhesive film 12 are fixedly connected, the bonding strength between the first transparent adhesive film 11 and the second transparent adhesive film 12 and the glossy paper 2 is improved. Moreover, the combined effect of different anti-counterfeiting marks can increase the difficulty of counterfeiting and make it easier for consumers to identify.
[0052] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.
