Description

Technical Field

[0001] The present invention relates to the technical field of packaging bag products, and in particular to a white packaging bag with a cursor-free, centered, variable two-dimensional code printing and a manufacturing method thereof. Background Art

[0002] Multilayer film packaging bags are widely used in various packaging industries due to their excellent performance and environmental protection characteristics, which not only improve the functionality and reliability of packaging.

[0003] For example, the prior application with publication number CN209141609U discloses a packaging bag film and a packaging bag, which adopts a multi-layer film structure and is bonded into a whole by an adhesive layer, has good heat sealing and flexibility, and has good sealing strength and the function of easy tearing of the finished product. However, the preparation process of this packaging bag is complicated, and it is not conducive to directly printing anti-counterfeiting marks on the surface of the packaging bag.

[0004] In order to identify authenticity and prevent counterfeit or forged goods in the medical, catering and important goods logistics fields, products or packaging bags need to be anti-counterfeited. Variable QR code is a special QR code, its content can change dynamically according to different parameters or conditions. Compared with traditional static QR code, variable QR code can update data in real time, making each QR code unique. Through encryption and dynamic generation, variable QR code is more difficult to copy or tamper with, improving security. At the same time, it can also track the number of scans, location and time of the variable QR code, and verify and check with the background database, which plays an important role in enhancing user experience and ensuring safety.

[0005] With the development of technology, in order to further improve the anti-counterfeiting property of products, the use of cursor-free variable QR codes has gradually increased. Cursor-free variable QR codes not only have variable content, but also have no traditional positioning pattern. This design makes the QR code more concise visually and often appears in occasions where aesthetic design is highly valued, such as packaging bags, display cabinets, etc. At present, cursor-free variable QR codes for important items are mainly sprayed directly on packaging bags. After use, the packaging bags may be reused to fill non-original items, reducing the anti-counterfeiting property of the packaging bags.

[0006] Therefore, those skilled in the art are committed to developing a white packaging bag and a production method for printing a cursor-free, centered, variable two-dimensional code, which is beneficial to improving the strength of the packaging bag and improving the anti-counterfeiting property. Summary of the invention

[0007] The technical problem to be solved by the present invention is to provide a white packaging bag with a cursor-free, centered, variable two-dimensional code printing and a production method, which is beneficial to improving the strength of the packaging bag and improving the anti-counterfeiting property. The technical solution of the present invention to solve the above technical problems is as follows: A white packaging bag with a cursor-less, centered, variable two-dimensional code printed thereon, comprising a packaging bag belt body, wherein the packaging bag body has a front side, a back side, and a first side surface and a second side surface connecting the front side and the back side; The front side, the back side, the first side and the second side all include an outer film, a middle film and an inner film arranged in sequence, the outer film and the inner film are EVOH films or PVDC films, and the outer film, the middle film and the outer film are synchronously co-extruded; A second separation two-dimensional code is printed on the back seal, and a first separation two-dimensional code is printed on the front. The first separation two-dimensional code and the second separation code are used to be spliced ​​into a complete two-dimensional code.

[0008] The beneficial effects of the above scheme are as follows: the inner film, the middle film and the outer film are co-extruded synchronously, and have a distinct hierarchical structure. The middle film has a distinct interface with the inner film and the outer film, so that the middle film can be used as a skeleton film, and the inner film and the outer film are used as coating films, so that the packaging bag is more stable. During the tearing process of the packaging bag, the inner film or the outer film is broken and torn first, while the influence of the middle film is small. The packaging bag still has the use characteristics, the strength of the packaging bag is improved, and the service life of the packaging bag is extended; A second separation QR code is printed on the sealing portion of the packaging bag. After the packaging bag is torn open, the second separation QR code and the first separation QR code are spliced ​​into a complete QR code, thereby improving the anti-counterfeiting property of the packaging bag.

[0009] At the same time, the outer film and the inner film are EVOH layers or PVDC layers, which is conducive to directly printing the QR code on the surface of the white packaging bag, thereby improving the overall preparation efficiency of the packaging bag.

[0010] A non-cursor centered variable two-dimensional code printed white packaging bag and a manufacturing method thereof, which is applied to the non-cursor centered variable two-dimensional code printed white packaging bag as described above, comprises the following steps: S100. Design a primary QR code according to the size, color and other visual elements of the QR code; S200. Inserting a variable data source into the primary QR code to form a variable QR code; S300. The variable QR code formed in step S200 is made into a variable QR code without a cursor by software; S400. The cursor-free variable QR code made in S300 is separated into two parts by software to form a first separated QR code and a second separated QR code; S500. Print the first partitioned QR code prepared in step S400 at the center of the white packaging bag; S600. Print the second partitioned two-dimensional code made in step S400 on a printing film, and the printing film and the white packaging bag are sealed as one.

[0011] The beneficial effects of adopting the above scheme are as follows: a primary QR code is first designed according to the color, size and other visual elements of the QR code, and then a variable QR code and a cursor-free variable QR code are sequentially made, and the cursor-free variable QR code is separated into a first separated QR code and a second separated QR code, and then printed on the center position of the white packaging bag and the printed film respectively, the QR code in the center position retains the aesthetics of the white packaging bag, and at the same time, differentiated visual elements can be printed in the center position to improve the aesthetics of the white packaging bag, the printed film is integrated with the seal of the white packaging bag, and after the printed film is torn off from the seal, it is spliced ​​with the QR code in the center position to form a complete QR code, thereby improving the anti-counterfeiting property of the packaging bag; At the same time, since the printed film must be torn off and spliced ​​with the first separation code before scanning and verification, the white packaging bag is opened after the printed film is torn off, thereby ensuring that the white packaging bag has not been opened before the cursor-free variable QR code is spliced ​​(if the printed film has been opened, it cannot be restored to the original seal and made into one piece), thereby further improving the anti-counterfeiting property of the packaging bag; Moreover, after the printed film on the white packaging bag is torn off and verified, the cursor-free variable QR code is used for secondary verification, thereby ensuring that the white packaging bag is disposable and preventing the packaging bag from being reused to fill non-original items after use, thereby reducing the anti-counterfeiting property of the packaging bag.

[0012] Based on the above technical solution, the present invention can also be improved as follows.

[0013] Furthermore, after the variable two-dimensional code is formed in step S200, the error correction level of the variable two-dimensional code is set by software.

[0014] The beneficial effect of adopting the above further solution is that the rate of scanning verification is increased after the error correction level is set.

[0015] Furthermore, in step S500, after the first partitioning two-dimensional code is printed at the center of the white packaging bag, a layer of anti-counterfeiting film is pasted on the first partitioning two-dimensional code, and a static two-dimensional code is printed on the anti-counterfeiting film.

[0016] The beneficial effect of adopting the above further solution is that the static two-dimensional code is used to decode the basic information of the packaging bag, such as product, logistics, etc., and is also used to cover the first separation two-dimensional code.

[0017] Furthermore, in step S600, the second separated two-dimensional code is mirrored and then printed on a printing film.

[0018] The beneficial effect of adopting the above further solution is that the second separated QR code after mirroring further improves the anti-counterfeiting property and avoids direct splicing with the first separated QR code after direct photography.

[0019] Furthermore, in step S500, when the first separation two-dimensional code is printed at the center of the white packaging bag, at least one positioning point is also printed on the side of the first separation two-dimensional code; In step S600, positioning circular holes matching the positioning points are printed on the printing film.

[0020] The beneficial effect of adopting the above further solution is that the cooperation between the positioning points and the positioning circular holes facilitates the rapid splicing of the first separation two-dimensional code and the second separation two-dimensional code into one, which is beneficial for subsequent scanning and verification.

[0021] Furthermore, in step S500 and step S600, the first separation two-dimensional code and the second separation two-dimensional code are both printed with black ink.

[0022] The beneficial effect of adopting the above further solution is that black ink printing on a white packaging bag increases the color contrast of the QR code, thereby facilitating quick scanning of the cursor-free variable QR code.

[0023] Further, in step S600, printing the second separated two-dimensional code on the printing film includes the following steps: S610. Transferring the black thermal sublimation ribbon to the intermediate transfer film to form a prefabricated second partition QR code; S620. Transfer the pre-coating film at the center of the white packaging bag, the pre-coating film being made of a thermally conductive resin; S630. The prefabricated second separated two-dimensional code prefabricated in step S610 is brought into contact with the surface of the pre-coating film in step S620, and rolled and cured so that the second separated two-dimensional code on the intermediate transfer film is transferred to the pre-coating film.

[0024] The beneficial effect of adopting the above-mentioned further scheme is: the black carbon ribbon is transferred to the intermediate film and prefabricated into a second separation two-dimensional code, the white packaging bag is transferred to the pre-coated film, and then the prefabricated second separation two-dimensional code is roller-cured onto the pre-coated film to ensure the integrity of the second separation code and avoid errors in direct printing due to uneven surface of the white packaging bag. At the same time, the print head or printing head is not directly used for printing or printing, thereby improving the stability of the ink on the white packaging bag.

[0025] Furthermore, in step S620, the transfer thickness of the pre-coating film is 3 μm to 10 μm.

[0026] The beneficial effect of adopting the above further solution is that the pre-coating film with appropriate thickness is conducive to the subsequent rapid curing and forming of the printed pattern.

[0027] Furthermore, in step S610 , the transfer thickness of the intermediate transfer film is 10 μm to 20 μm.

[0028] The beneficial effect of adopting the above further solution is that the intermediate transfer film with suitable thickness is conducive to the rapid transfer of the prefabricated pattern to the pre-coating film during the subsequent rolling and fixing. BRIEF DESCRIPTION OF THE DRAWINGS
