Description

Technical Field

[0001] The utility model relates to the technical field of packaging bags, in particular to a gold-stamping packaging bag. Background Art

[0002] The hot stamping process uses the principle of heat transfer to transfer the aluminum layer in the electroplated aluminum to the surface of the substrate to form a special metal effect. Hot stamping packaging bags are hot stamping on the packaging bags, making the packaging bags more visually appealing and more beautiful.

[0003] Since the surface of the plastic film is very smooth, it is difficult for the hot stamping to be directly attached to the packaging bag. Therefore, an additional layered structure is required to improve the adhesion of the hot stamping layer, resulting in higher production costs. In addition, some packaging bags require heat preservation, but some hot stamping packaging bags do not have heat preservation function.

[0004] For example, Chinese patent application number: CN202022650934.3 discloses a packaging bag with a hot stamping effect. It specifically discloses that "the hot stamping material layer includes a release layer fixedly connected to the outer side of the packaging bag base layer, a hot stamping layer is arranged on the outer side of the release layer, a hot glue layer is filled between the release layer and the hot stamping layer, and a hot stamping film is fixedly connected to the outer side of the hot stamping layer. The connection between the release layer and the hot stamping layer is achieved through the hot glue layer. The surface of the hot stamping film can be text or pattern, which can greatly improve the appearance grade of the entire plastic packaging bag. "It can be seen that the hot stamping layer is fixed to the base layer of the packaging bag through the release layer, and the manufacturing cost is relatively high. In addition, this kind of packaging bag cannot meet the insulation requirements. Utility Model Content

[0005] In view of this, the utility model aims at the deficiencies of the prior art, and its main purpose is to provide a hot stamping packaging bag, which not only can directly set the hot stamping layer on the plastic film layer, but also has a heat preservation function, thereby overcoming the deficiencies of the prior art.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The present application provides a hot stamping packaging bag, comprising a plate body, on which a plurality of first folds are arranged; the plate body comprises a first side plate, a second side plate, a third side plate, a fourth side plate, a first connecting plate, a first bottom plate, a second bottom plate, a third bottom plate, and a fourth bottom plate; the first side plate, the second side plate, the third side plate, the fourth side plate, the first connecting plate, the first bottom plate, the second bottom plate, the third bottom plate, and the fourth bottom plate are folded and connected to form a packaging bag; the second side plate and the fourth side plate are provided with handles and Velcro, and the Velcro can close the opening of the packaging bag;

[0008] The plate body comprises a reflection layer, a heat preservation layer, a plastic film layer, a corona layer and a hot stamping layer which are arranged in sequence from the inside to the outside.

[0009] Preferably, a first partition plate and a second partition plate are provided in the packaging bag; the second partition plate is interleaved and engaged with the first partition plate; the first partition plate and the second partition plate divide the accommodating space inside the packaging bag into a plurality of storage compartments.

[0010] Preferably, the handle is riveted to the second side panel and the fourth side panel and is located on the upper side of the Velcro.

[0011] Preferably, the reflective layer is aluminum foil or silver foil.

DETAILED DESCRIPTION

[0025] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0026] Please refer to Figures 1 to 4 As shown, it shows the specific structure of a preferred embodiment of the utility model, which is a gold-stamping packaging bag.

[0027] The corona layer 14 is generated on the plastic film layer 13 by corona, so the hot stamping position of the plastic film layer 13 becomes rough, and the hot stamping layer 15 can be directly arranged on the plastic film layer 13. At the same time, the reflective layer 11 and the heat-insulating layer 12 make the packaging bag have a heat-insulating effect, and the application range is wider.

[0028] The present application provides a hot stamping packaging bag, including a plate body 10, on which a plurality of first folds are arranged; the plate body 10 has a first side plate 110, a second side plate 111, a third side plate 112, a fourth side plate 113, a first connecting plate 114, a first bottom plate 115, a second bottom plate 116, a third bottom plate 117, and a fourth bottom plate 118; the first side plate 110, the second side plate 111, the third side plate 112, the fourth side plate 113, the first connecting plate 114, the first bottom plate 115, the second bottom plate 116, the third bottom plate 117, and the fourth bottom plate 118 are folded and connected to form a packaging bag; the second side plate 111 and the fourth side plate 113 are provided with handles 20 and Velcro 21, and the Velcro 21 can close the opening of the packaging bag; the plate body 10 includes a reflective layer 11, a heat-insulating layer 12, a plastic film layer 13, a corona layer 14, and a hot stamping layer 15, which are arranged in sequence from the inside to the outside. The plastic film layer 13 is subjected to corona treatment, which is a surface treatment technology that changes the surface properties of the plastic by acting on the plastic surface with a high-frequency high-voltage electric field. This change is mainly to make the plastic surface easier to print, coat or bond, etc. More specifically, the corona machine is also called an impact machine or a spark machine. The surface tension and internal tension of the plastic film just blown out of the film blowing machine are both small (it can also be understood that the surface is relatively smooth). This makes it difficult for the hot stamping layer 15 to adhere and easy to fade. After the plastic film layer is subjected to corona treatment, the surface tension of the plastic film layer becomes larger (it can also be considered that the surface of the film is roughened by the corona, but this is microscopic and cannot be detected by the naked eye). In this way, the hot stamping layer 15 can be directly attached to the film without falling off. The hot stamping process uses the principle of hot pressing transfer to transfer the aluminum layer in the electroplated aluminum to the surface of the substrate to form a special metal effect. Since the main material used for hot stamping is electroplated aluminum foil, hot stamping is also called electroplated aluminum hot stamping. The reflective layer 11, the heat-insulating layer 12, the plastic film layer 13, the corona layer 14, and the hot stamping layer 15 together form a composite structure. The reflective layer 11 reflects heat, and the heat-insulating layer 12 provides heat preservation. Therefore, the hot stamping packaging bag has a good heat preservation effect. Please refer to Figure 4 As shown, the steps of forming the packaging bag are as follows: 1. The Velcro 21 is attached to the second side panel 111 and the fourth side panel 113. 2. The first side panel 110, the second side panel 111, the third side panel 112, the fourth side panel 113, and the first connecting panel 114 are folded in sequence along the corresponding first folds to form a cylindrical structure, and the first connecting panel 114 is bonded or riveted to the first side panel 110. 3. The first bottom panel 115, the second bottom panel 116, the third bottom panel 117, and the fourth bottom panel 118 are folded inward by 90 degrees, so that the top of the cylindrical structure will be blocked. At this point, the packaging bag has been formed.

[0029] Preferably, the packaging bag is provided with a first partition plate 122 and a second partition plate 123; the second partition plate 123 is intermittently engaged with the first partition plate 122; the first partition plate 122 and the second partition plate 123 divide the storage space inside the packaging bag into a plurality of storage compartments 124. The second partition plate 123 is provided with an interlocking opening, and after a plurality of second partition plates 123 are intermittently engaged with the first partition plate 122, the storage space inside the packaging bag is divided into a plurality of storage compartments 124, and articles are placed in the storage compartments 124, so that the articles can be prevented from shaking and the stability is improved.

[0030] Preferably, the handle 20 is riveted to the second side panel 111 and the fourth side panel 113, and is located on the upper side of the Velcro 21. The handle 20 is a plastic tape, a nylon bag, a belt, a rope, etc. The handle 20 is riveted to the second side panel 111 and the fourth side panel 113 by rivets, and is located on the upper side of the Velcro 21, which can prevent external heat from entering the packaging bag.

[0031] Preferably, the reflective layer 11 is aluminum foil or silver foil. In this embodiment, the reflective layer 11 is aluminum foil with a thickness ranging from 0.05 mm to 0.2 mm, such as 0.06 mm, 0.08 mm, 0.1 mm, etc.

[0032] Preferably, the insulation layer 12 is one of polyethylene foam, polypropylene foam and polystyrene foam. In this embodiment, the insulation layer 12 is polyethylene foam. The thickness of the insulation layer 12 is between 1-2 mm.

[0033] Preferably, the plastic film layer 13 is one of polyethylene film, polypropylene film, and PET film. The plastic film layer 13 is one of laser polyethylene film, laser polypropylene film, and laser PET film. The thickness of the plastic film layer 13 is between 0.1 mm and 1 mm. Laser film generally adopts computer dot matrix lithography technology, 3D true color holographic technology, multiple and dynamic imaging technology, etc. After the plastic film layer 13 has a laser effect, it can better set off the visual effect of the hot stamping layer 15, making the packaging bag more cool and

[0034] Preferably, a second connecting plate 120 and a carrying plate 121 extend in sequence from the bottom of the second bottom plate 116. When in use, the second connecting plate 120 is folded on the second bottom plate 116, and then the carrying plate 121 is folded from the second connecting plate 120, so that the carrying plate 121 is placed on the inner side of the second bottom plate 116 and the fourth bottom plate 118, which can improve the carrying capacity of the packaging bag and also improve the heat preservation capacity.

[0035] Preferably, an anti-counterfeiting label 125 is attached to the opening of the packaging bag. The anti-counterfeiting label 125 is one of a laser anti-counterfeiting label 125, an electronic code anti-counterfeiting label 125, a two-dimensional code anti-counterfeiting label 125, an anti-counterfeiting label 125 that leaves words when it is opened, a temperature-sensitive or humidity-sensitive anti-counterfeiting label 125, a fluorescent or light-sensitive anti-counterfeiting label 125, and an RFID anti-counterfeiting label 125. The anti-counterfeiting label 125 can improve the anti-theft capability and prevent the items from being stolen.

[0036] In summary, the design focus of the utility model is that the corona layer 14 is produced on the plastic film layer 13 through the corona process, so that the hot stamping position becomes rough, so the hot stamping layer 15 can be directly set on the plastic film layer 13. The reflective layer 11 and the heat-insulating layer 12 make the packaging bag have a heat-insulating effect, and the application range is wider.
