Description

Technical Field

[0001] This utility model relates to the field of plastic film technology, specifically to a shallow-screen printing film. Background Technology

[0002] Light-screen printing film is a high-quality printing material widely used in packaging, labeling, and advertising printing. It boasts strong printing performance, making it suitable for projects requiring high printing precision, such as signs, trademarks, and instruction manuals. Its printed patterns are clear and vibrant, meeting the demands of high-end printed materials.

[0003] Chinese utility model patent CN206605870U discloses a high-transparency shallow-screen printed film, comprising a polypropylene resin core layer, an anti-puncture layer fixedly disposed on the upper surface of the polypropylene resin core layer, a shallow-screen printed layer fixedly disposed on the upper surface of the anti-puncture layer, a transparent protective layer fixedly disposed on the upper surface of the shallow-screen printed layer, and a first antibacterial layer fixedly disposed on the upper surface of the protective layer; an aluminum-plated layer fixedly disposed on the lower surface of the polypropylene resin core layer, and a second antibacterial layer fixedly disposed on the lower surface of the aluminum-plated layer; a storage groove is provided on the upper surface of the protective layer, and an anti-counterfeiting label is disposed within the storage groove, with micro-sized anti-counterfeiting information provided on the upper surface of the anti-counterfeiting label. The above technical solution has a reasonable and simple structural design, possesses antibacterial and bactericidal functions, good anti-counterfeiting properties, is not easily punctured, and has a long service life.

[0004] However, the aforementioned shallow-screen printing film lacks the function of isolating or waterproofing the film itself. If effective moisture-proof and dust-proof measures are not taken, the surface of the film may become damp, moldy, or dusty during transportation or storage. Excessive humidity will cause the film material to absorb moisture, resulting in a certain degree of expansion and deformation. This deformation will directly affect the quality of the printed product, making it impossible to accurately align the patterns and text, thus affecting the overall aesthetics and usability.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This utility model discloses a shallow screen printing film, including a printing film body 1. A top waterproof and dustproof protective film 2 is movably connected to one side of the surface of the printing film body 1. A left opening 4 is fixedly connected to one side of the top waterproof and dustproof protective film 2. A right opening 6 is fixedly connected to the other side of the top waterproof and dustproof protective film 2. A bottom waterproof and dustproof protective film 3 is movably connected to the surface of the other side of the printing film body 1. A left auxiliary opening 5 is fixedly connected to one side of the bottom waterproof and dustproof protective film 3. A right auxiliary opening 7 is fixedly connected to the other side of the bottom waterproof and dustproof protective film 3. A rectangular adhesive 8 is provided between the bottom waterproof and dustproof protective film 3 and the top waterproof and dustproof protective film 2.

[0023] A first antibacterial layer 101 is movably disposed on the top of the printed film body 1. A thin film protective layer 102 is disposed below the first antibacterial layer 101. A shallow screen printing layer 104 is disposed below the thin film protective layer 102. An antistatic layer 103 is fixedly disposed on the upper surface of the shallow screen printing layer 104. A reinforcing layer 105 is disposed below the shallow screen printing layer 104. A first reinforcing wire and a second reinforcing wire are fixedly disposed inside the reinforcing layer 105. The first reinforcing wires are all fixedly disposed inside the reinforcing layer 105 and evenly distributed from front to back. The second reinforcing wires are all fixedly disposed inside the reinforcing layer 105 and evenly distributed from left to right. A polypropylene resin core layer 106 is movably disposed below the reinforcing layer 105. An aluminum plating layer 107 is movably disposed below the polypropylene resin core layer 106. A second antibacterial layer 108 is movably disposed below the aluminum plating layer 107.

[0024] Specifically, the surface areas of the top waterproof and dustproof protective film 2 and the bottom waterproof and dustproof protective film 3 are both larger than that of the printed film body 1.

[0025] In this embodiment, by setting the surface areas of the top waterproof and dustproof protective film 2 and the bottom waterproof and dustproof protective film 3 to be larger than the surface area of ​​the printed film body 1, the top waterproof and dustproof protective film 2 and the bottom waterproof and dustproof protective film 3 can tightly protect and isolate the printed film body 1 with the cooperation of the rectangular adhesive 8, which greatly reduces the possibility that the product surface will be damp, moldy or contaminated with dust before it is unsealed.

[0026] Specifically, the first antibacterial layer 101, the film protective layer 102, the shallow screen printing layer 104, the reinforcing layer 105, the polypropylene resin core layer 106, the aluminum plating layer 107, and the second antibacterial layer 108 are sequentially co-extruded from top to bottom.

[0027] In this implementation scheme, by setting multiple different layers as multi-layer co-extrusion connections, it can not only achieve efficient barrier against bacteria, dust, moisture, etc., but also improve the functional diversity of the product.

[0028] Specifically, the connection between the intersection of the first reinforcing wire and the second reinforcing wire is a fixed connection.

[0029] In this embodiment, by setting the connection relationship between the intersection of the first reinforcing wire and the second reinforcing wire to a fixed connection, the strength of the reinforcing layer 105 can be effectively improved, making the printed film body 1 less susceptible to damage.

[0030] Specifically, both the first reinforcing wire and the second reinforcing wire are made of nylon.

[0031] In this embodiment, by setting both the first reinforcing wire and the second reinforcing wire to be made of nylon, they have high strength and toughness, enabling the reinforcing wire to withstand greater tensile and compressive forces and to be less prone to breakage or deformation.

[0032] Specifically, protective edges 109 are fixedly connected to both sides of the printed film body 1. The connection between one side of the protective edge 109 and one side of the first antibacterial layer 101, the film protective layer 102, the shallow screen printing layer 104, the reinforcing layer 105, the polypropylene resin core layer 106, the aluminum plating layer 107, and the second antibacterial layer 108 is fixed.

[0033] In this embodiment, by fixing protective edges 109 to both sides of the printing film body 1, the protective edges 109 can reduce friction and collision of the printing film body 1 during processing, transportation and use, thereby reducing the possibility of the printed content being scratched or damaged.

[0034] When in use, because the surface area of ​​the auxiliary openings on the left and right sides is designed to be larger than that of the openings on the left and right sides, the user can more easily separate the auxiliary openings on the left and right sides from the openings on the right and left sides, tear off the top waterproof and dustproof protective film 2 and the bottom waterproof and dustproof protective film 3, and take out the printed film body 1 before using this product.

[0035] In summary, this shallow-screen printed film, by setting a top waterproof and dustproof protective film 2, a bottom waterproof and dustproof protective film 3, and a rectangular adhesive 8, can tightly protect and isolate the printed film body 1 inside the film through the combined use of the top waterproof and dustproof protective film 2 and the bottom waterproof and dustproof protective film 3 and the rectangular adhesive 8, ensuring that the printed film body 1 is not contaminated by external moisture and dust when unopened. By setting a reinforcing layer 105, a first reinforcing wire, and a second reinforcing wire, and using high-strength and high-toughness nylon reinforcing wire as the main filling structure of the reinforcing layer 105, the printed film body 1 is less likely to be physically damaged during transportation, reducing the possibility of the printed film body 1 being damaged or deformed due to compression and friction, thereby more stably protecting its aesthetics and usability.
