Technical Field

[0001] The utility model belongs to the technical field of multi-layer slurry or paper pulp composition of IPC classification D21H27 / 30, and particularly relates to a double-layer coated cross-bonded die-cutting board for packaging printing. Background Art

[0002] As an important packaging product, carton plays an indispensable role in commodity packaging and logistics transportation. It has the characteristics and advantages of being light and easy to carry, low cost, environmentally friendly and sustainable, and strong printing adaptability, so it is widely used in various fields and industries. Carton is a widely used packaging product, mainly used for packaging commodities or as an outer layer of protection for items. Carton is a widely used packaging product, mainly used for packaging commodities or as an outer layer of protection for items. It is widely used to package commodities of various shapes and sizes, such as electrical appliances, household items, food, etc. It not only plays a protective role in logistics transportation, but can also be used for storage, display and marketing of commodities.

[0003] The carton making process includes steps such as determining product size, cutting cardboard size, making carton creasing, carton forming, and packing and warehousing. Required equipment: Special equipment such as paper sorting machine, printing slotting machine, and box nailing machine are used for carton production and processing. According to different materials, cartons can be divided into corrugated boxes, single-layer cardboard boxes and other types. Among them, corrugated boxes are the most common and have good cushioning performance and compressive strength. The carton structure usually consists of lining paper, corrugated paper, core paper and face paper. The face paper and lining paper are usually made of tea board paper or kraft paper, while the core paper is made of corrugated paper. These papers are bonded together to form a cardboard with a certain thickness and strength.

[0004] In packaging printing, double lamination is a process of covering the surface of printed matter with two layers of plastic film in order to enhance the durability, waterproofness and aesthetics of the printed matter. In this process, the two layers of film are cross-bonded together by a specific adhesive to form a protective layer, which effectively extends the service life of the printed matter.

[0005] The die-cutting board is an important tool used in the die-cutting process, which determines the final shape and size of the printed product. The die-cutting board is usually composed of a wooden board, a steel knife line, an indentation line, and a hole groove. Its production process requires precise design and processing to ensure that the die-cut printed product meets the design requirements.

When there is a conflict, the definitions in this specification shall prevail. In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only embodiments of a part of the present invention, not all embodiments.

[0029] In the utility model, by combining double-layer lamination and cross-bonding technology, the die-cutting board can ensure neat and smooth edges when cutting printed products, thereby improving the overall aesthetics of the product. At the same time, this combined process can also increase the structural strength and stability of the printed products, making them less susceptible to damage during transportation and storage.

[0030] The utility model comprises: a core plate 1, an upper covering film 2, a lower covering film 3 and a glue application surface 4.

[0031] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0032] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.

[0033] The content of the present invention can be more easily understood by selecting the following preferred implementation methods and embodiments of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by ordinary technicians in the field to which the present invention belongs. When there is a conflict, the definition in this specification shall prevail.

[0034] Embodiment 1: As attached Figure 1 As shown, an upper coating 2 and a lower coating 3 are respectively provided on the upper and lower surfaces of the core plate 1 , and a glue application surface 4 is provided in a local area on the upper coating 2 on the upper surface of the core plate 1 .

[0035] In the above, the glue application surface 4 adopts hot melt adhesive. During production, the coating machine can be directly adopted for on-line production.

[0036] Preferably, the upper film 2 and the lower film 3 are made of PE film with a thickness between 0.008 and 0.012 mm, and are coated with a slow-release antibacterial agent, which is an inorganic nano-silver ion antibacterial agent. The antibacterial agent uses a colorless and transparent nano-silver solution with a particle size of 0.2-0.4 nm as the main antibacterial raw material, is resistant to high temperatures, and has an antibacterial rate of up to 99%.

[0037] Preferably, the double-layer lamination of the upper lamination 2 and the lower lamination 3 means that a layer of film is covered on both sides of the printed matter, usually polyester film. This lamination can provide additional protection, making the printed matter more durable, while enhancing the visual effect, making the picture brighter and better in texture.

[0038] In the embodiment of the utility model, the upper and lower surfaces of the core board 1 are respectively provided with an upper coating 2 and a lower coating 3 to basically form a printing die-cutting board, which is an important material used in the die-cutting process and can accurately cut and shape printed products according to design requirements.

[0039] Embodiment 2: As attached Figure 2 As shown, in Example 1, a layer of surface release film 5 is further covered on the surface of the upper covering film 2 and the lower covering film 3 provided with the glue application surface 4.

[0040] In the above, the surface release film 5 is a transparent film.

[0041] In particular, the surface release film 5 is a PE film with a thickness between 0.008-0.012 and is coated with a silicone release agent.

[0042] In the embodiment of the utility model, the two technologies of double-layer lamination and die-cutting are combined to provide better protection and molding effects for printed products. In the packaging printing process, by using double-layer lamination technology, the lamination can protect the base material from wear and corrosion, thereby extending the service life of the die-cutting board. The lamination can increase the gloss and smoothness of the surface of the die-cutting board, making it more beautiful in appearance. It can protect the printed products from damage by dirt, moisture and wear, while improving the visual appeal and texture of the product. The die-cutting board ensures that the printed products can be accurately cut and molded according to the design requirements to meet the actual needs of customers. At the same time, the lamination of multiple colors can also add more visual effects to the die-cutting board. The lamination has a certain waterproof performance and can prevent moisture from penetrating into the inside of the die-cutting board.

[0043] In addition, the production cost of double-layer laminated cross-bonded die-cutting boards may be higher than that of single-layer die-cutting boards. This is mainly because the double-layer lamination and special cross-bonding technology increase the complexity of the production process and material costs. Moreover, the technical requirements are high: the production of double-layer laminated cross-bonded die-cutting boards requires high-precision equipment and technical support, and the technical requirements of the manufacturer are high. If the technology is not up to standard, it may lead to unstable product quality or other problems. In the process of double-layer laminated cross-bonding, if the bonding is uneven or there are problems such as bubbles, it may affect the performance and appearance quality of the die-cutting board. Therefore, it is necessary to strictly control the bonding process and quality inspection during the production process.

[0044] Embodiment 3: As attached Figure 3 As shown, the core board 1 is formed by bonding an upper board 101 and a lower board 102, and vertically intersecting longitudinal glue lines 601 and transverse glue lines 602 are respectively applied on the bonding surfaces of the upper board 101 and the lower board 102. After bonding, an adhesive layer 6 with a grid bonding structure is formed on the bonding surfaces of the upper board 101 and the lower board 102, which is uniform and saves adhesive materials.

[0045] In the above, a longitudinal glue line 601 or a transverse glue line 602 is set on one or both surfaces of the upper film 2 or the lower film 3 of the core board 1, and then the surface of the longitudinal glue line 601 or the transverse glue line 602 is covered with a surface release film 5.

[0046] In the above, it can be expanded that a third layer of plywood is arranged between the upper plate 101 and the lower plate 102; the upper plate 101, the lower plate 102 and the third layer of plywood are bonded to form the core plate 1.

[0047] In the embodiment of the utility model, the die-cutting board has higher durability through double-layer film cross-bonding. Due to the use of special die-cutting process and precise cross-bonding technology, the double-layer film cross-bonding die-cutting board can ensure the accuracy and consistency of die-cutting and meet the needs of high-precision cutting.

[0048] In the embodiment of the utility model, cross bonding means that during the double-layer lamination process, two layers of film are bonded together in a cross manner. This bonding method can increase the firmness and stability of the lamination and prevent the film from falling off or warping. At the same time, cross bonding can also improve the folding resistance and wear resistance of the printed matter.

[0049] The implementation principle of this embodiment is as follows: during the preparation process by the coating machine, the surfaces on both sides of the core board 1 are covered with an upper film 2 and a lower film 3. Then, according to the design of the printing plate, a gluing surface 4 is set, and a surface release film 5 is covered on the outside of the gluing surface 4; next, for a more complex core board 1 structure; when the core board 1 has a multi-layer structure inside, a core board 1 with a mesh adhesive layer 6 bonding surface is prepared through a heat-sealing process and equipment; finally, a gluing surface 4 and a surface release film 5 are set on the surface of the core board 1 covered with the upper film 2 and the lower film 3. When this double-layer coated cross-bonded die-cutting board for printing is used, die-cutting is first performed, and then the surface release film 5 is removed, and components are bonded on the gluing surface 4 to assemble a synthetic packaging product.

[0050] Based on the above embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention, so as to avoid exhaustively listing all implementation methods that are unnecessary and impossible to list comprehensively.
