[0037] In order to make the technical features and effects of the present application more obvious, the technical solution of the present application will be further described below with reference to the accompanying drawings. The present application can also be illustrated or implemented with other different specific examples. Any equivalent transformation made by any person skilled in the art within the scope of the claims belongs to the protection scope of the present application.

[0038] The illustrative embodiments of the present application and their descriptions are used to explain the present application, but do not limit the present application. In addition, the elements / components using the same or similar reference signs in the drawings and the embodiments are used to represent the same or similar parts.

[0039] Regarding the "first" and "second" used in this article, they do not particularly refer to the order or sequence, nor are they used to limit the present application. They are only used to distinguish the elements or operations described with the same technical terms.

[0040] As Figure 1 , Figure 2 shown, Figure 1 It is a cross-sectional view of a single packaging unit according to an embodiment of the present application, Figure 2This is a top view of the packaging material structure according to an embodiment of the present application. This embodiment provides a packaging material structure for making product packaging, and the product packaging is used for filling fluid foods such as milk, yogurt, etc., so as to transport and sell the fluid foods. The product packaging made of the packaging material structure provided by the present application can ensure that the two-dimensional code will not be stolen and scanned before the product is sold.

[0041] Specifically, the packaging material structure has a plurality of single packaging units 100. Each single packaging unit 100 includes a base material 10, a first patch 20 and a second patch 30. Among them, the base material 10 of each single packaging unit 100 has a through hole 101 and a two-dimensional code 102.

[0042] The first patch 20 is fixed on one side of the base material 10 for covering the through hole 101 and at least part of the two-dimensional code 102. When the two-dimensional code 102 is partially covered by the first patch 20, the information cannot be read by the recognition device.

[0043] The second patch 30 is fixed on the other side of the base material 10 for covering the through hole 101.

[0044] Specifically, the base materials of the single packaging units are integrally formed.

[0045] The two-dimensional code can be a two-dimensional code of any format, and the two-dimensional codes on each single packaging unit are different from each other.

[0046] The through hole can be a round hole, an oval hole, etc. The present application does not limit the specific shape and size of the through hole.

[0047] The first patch and the second patch can be square, rectangular, circular or irregular shapes, etc. The present application does not limit the specific shape and size of the first patch and the second patch. For the sake of increasing interest, patterns, product usage instructions, etc. can also be printed on the first patch.

[0048] The second patch is used to ensure strength and sealing, preventing the through hole from being easily broken due to extrusion or vibration. The first patch is used for the user to pull up to obtain the through hole. Optionally, in order to facilitate the user to pull up the first patch on the through hole, at least part of the edge area of the first patch is not fixed on the base material.

[0049] In some embodiments, in order to avoid the first patch being too large in size due to covering the two-dimensional code, thus wasting materials, the two-dimensional code is arranged around the through hole.

[0050] In some embodiments, the first patch and the second patch can be fixed by hot pressing. In other embodiments, the first patch and the second patch can also be fixed by gluing. The present application does not limit the specific fixing method of the first patch and the second patch, and any method that does not affect food safety can be adopted.

[0051] In some embodiments, the first patch and the second patch are attached to each other at the through hole, so that when the first patch is pulled up, the second patch can be pulled open at the same time, and the through hole of the package is opened.

[0052] In some embodiments, the first patch includes an aluminum foil layer and a PE layer, and the aluminum foil layer is located above the PE layer. The second patch includes a PE layer.

[0053] In some embodiments, the substrate is composed of a base layer, a printing layer, and a waterproof layer. The printing layer is located above the base layer, and the waterproof layer is located above the printing layer; the two-dimensional code is provided on the printing layer. Other areas of the printing layer are printed with product information, such as advertising design patterns, production-related information, etc.

[0054] Furthermore, the substrate further includes a gas barrier layer and a sealant layer, and the gas barrier layer and the sealant layer are sequentially located below the base layer.

[0055] In some embodiments, the substrate includes a base layer, a printing layer, a first waterproof layer, a coating layer, and a second waterproof layer. The printing layer is located above the base layer, the first waterproof layer is located above the printing layer, at least part of the area on the first waterproof layer is coated with a coating layer, a two-dimensional code is printed on the coating layer or a two-dimensional code label is pasted, and the second waterproof layer is located above the two-dimensional code or the two-dimensional code label.

[0056] As Figure 3 shown, Figure 3 is a flowchart of a method for producing a packaging material structure according to an embodiment of the present application. Specifically, the method includes:

[0057] Step 301: Produce a substrate with multiple single packaging units, and each substrate of the single packaging unit has a two-dimensional code. Specifically, in implementation, the two-dimensional codes on each single packaging unit are different from each other.

[0058] Step 302: Make a through hole in the substrate of each single packaging unit.

[0059] Step 303: Fix the first patch on one side of the substrate so that the first patch covers the through hole and at least part of the two-dimensional code.

[0060] Fix the second patch on the other side of the substrate so that the second patch covers the through hole.

[0061] Specifically, in implementation, the first patch and the second patch can be fixed on the substrate of the single packaging unit at the same time; or the first patch is fixed on one side of the substrate first, and then the second patch is fixed on the other side of the substrate; or the second patch is fixed on the other side of the substrate first, and then the first patch is fixed on one side of the substrate.

[0062] The following details the detailed processes of Step 302 and Step 303 with a specific embodiment.

[0063] Place the substrate 10 produced in step 301 on Figure 4 the production line shown. The substrate 10 is continuously conveyed by a motor, and the punching device 401 punches a through hole on the substrate at fixed time intervals; or punches holes according to a punching instruction, which is generated by the controller based on a positioning mark on a single packaging unit (the positioning mark can be recognized by an inductor). The patch pasting device 402 pastes the first patch and the second patch on the substrate at fixed time intervals so that the first patch and the second patch cover a through hole; or pastes according to a pasting instruction, which is generated by the controller based on a positioning mark on a single packaging unit. The first patch and the second patch are tightly adhered through hot pressing at the through hole, so that when the first patch is pulled up, the second patch can be pulled open at the same time, and the packaging opening through hole is opened.

[0064] As Figure 5 、 Figure 6 shown, Figure 5 and Figure 6 are schematic diagrams of the product packaging of the embodiments of the present application, and the product packaging is made of a single packaging unit in the packaging material structure described in any of the above embodiments.

[0065] Specifically, the product packaging described in this embodiment can be a standard cuboid, or a polyhedron with an inner concave or outer convex middle, and the present application does not limit its specific shape.

[0066] The user can open the through hole by pulling up the first patch and obtain a two-dimensional code at the same time, which can effectively prevent bacteria from entering the product due to inserting a straw to open the through hole. In addition, at least part of the area of the two-dimensional code structure is covered by the first patch, which can prevent the two-dimensional code from being stolen and scanned and invalidated before the product is sold, and protect the rights and interests of consumers to participate in activities by scanning the code (the code is the two-dimensional code on the product packaging).

[0067] The above is only used to illustrate the technical solutions of the present application. Any person of ordinary skill in the art can modify and change the above embodiments without departing from the spirit and scope of the present application. Therefore, the scope of the rights protection of the present application shall be subject to the scope of the claims.
