Description

Technical Field

[0001] This application relates to the field of label film technology, and in particular to a single-sided glossy weather-resistant label film. Background Technology

[0002] Single-sided gloss weather-resistant label film achieves high gloss, good weather resistance, and excellent printing results through special material formulations and manufacturing processes. Some single-sided gloss weather-resistant label films utilize materials such as PVC resin, organotin stabilizers, plasticizers, and UV resins. Through a multi-layered structural design, including a printing layer, flame-retardant layer, abrasion-resistant layer, moisture-proof layer, and weather-resistant layer, the overall performance of the label film is improved. Technically, single-sided gloss weather-resistant label film achieves its gloss and weather resistance by optimizing material ratios and manufacturing processes, such as calendering, embossing, and cooling. Its multi-layered structural design not only enhances the label's abrasion resistance and moisture resistance but also significantly extends its lifespan in outdoor environments through the addition of the weather-resistant layer.

[0003] Currently, Chinese utility model patent application CN 216084092U, published on March 18, 2022, provides a printable label film, including a label film body with polygonal pores on its surface having an average pore size between 2 and 10 μm. It features rapid ink absorption and strong ink adhesion, improving printing results.

[0004] In related technologies, printable label films have multiple polygonal pores on their surface, which leads to poorer weather resistance. Specifically, the presence of polygonal pores compromises the integrity of the label film, making it easier for ultraviolet rays, moisture, and oxygen in the air to penetrate the material, thereby accelerating the aging process. During outdoor use, ultraviolet radiation is a key factor causing label film fading. When the label film is exposed to ultraviolet light, the dye molecules absorb light energy, their energy levels increase, and a series of photochemical reactions occur, leading to the destruction of the dye molecules' stability and their decomposition and fading.

[0005] Therefore, it is necessary to provide a single-sided glossy weather-resistant label film to solve the above problems. Utility Model Content

[0022] Based on this, in order to improve the technical problem of poor weather resistance of label films in related technologies, which leads to easy fading of label films during outdoor use, the embodiments of this application provide the following solutions.

[0023] Please refer to the following: Figures 1 to 4 This application provides a single-sided gloss weather-resistant label film, which includes a substrate layer 1, an ink layer 2, an adhesive layer 3, a weather-resistant layer 5, a protective layer 6, and a wear-resistant layer 7.

[0024] The adhesive layer 3 is disposed on the substrate layer 1, the ink layer 2 is disposed on the side of the substrate layer 1 away from the adhesive layer 3, the weather-resistant layer 5 is disposed on the side of the ink layer 2 away from the substrate layer 1, the protective layer 6 is disposed on the side of the weather-resistant layer 5 away from the ink layer 2, and the wear-resistant layer 7 is disposed on the side of the protective layer 6 away from the weather-resistant layer 5.

[0025] In some embodiments, please refer to the following: Figures 1 to 4 The protective layer 6 includes a moisture-proof layer 61 and a flame-retardant layer 62. The flame-retardant layer 62 is disposed on the side of the weather-resistant layer 5 away from the ink layer 2, and the moisture-proof layer 61 is disposed on the side of the flame-retardant layer 62 away from the weather-resistant layer 5. The wear-resistant layer 7 includes a thermoplastic rubber layer 71 and a polyurea coating 72. The polyurea coating 72 is disposed on the side of the moisture-proof layer 61 away from the flame-retardant layer 62, and the thermoplastic rubber layer 71 is disposed on the side of the polyurea coating 72 away from the moisture-proof layer 61. The weather-resistant layer 5 is made of UV resin.

[0026] This design allows the UV resin to effectively block ultraviolet rays, preventing the label film from fading or aging due to prolonged exposure to sunlight. The cured UV resin coating has a high gloss, enhancing the label's aesthetics. UV curing technology offers fast curing speed and high production efficiency. Meanwhile, the moisture-proof layer 61 is composed of a waterproof and breathable membrane, which effectively prevents moisture penetration and protects the internal structure of the label film from the effects of a humid environment. The flame-retardant layer 62 is composed of a halogen-free flame-retardant PC film, which has excellent flame-retardant properties and remains stable at high temperatures, preventing the label film from burning. Halogen-free materials do not release toxic gases when burning, meeting environmental and safety standards. The wear-resistant layer 7 is composed of a thermoplastic rubber layer 71 and a polyurea coating 72, both of which have excellent wear resistance, effectively resisting friction and abrasion and extending the label film's lifespan. The thermoplastic rubber layer 71 provides good flexibility, allowing the label film to adapt to surfaces of different shapes. The polyurea coating 72 has high hardness, providing additional protection against scratches and impacts. This multi-layered structural design combines the advantages of various materials, providing comprehensive protection and enabling the label film to maintain good performance for a long time in harsh outdoor environments. Through the multiple protections of the weather-resistant layer 5, flame-retardant layer 62, moisture-proof layer 61, and abrasion-resistant layer 7, the service life of the label film is significantly extended, reducing the frequency of replacement.

[0027] In some embodiments, please refer to the following: Figures 1 to 2 The adhesive layer 3 includes a tensile adhesive layer 31, a self-adhesive adhesive 32, and adhesive posts 33. The tensile adhesive layer 31 is disposed on the side of the substrate layer 1 away from the ink layer 2, and a groove 34 is formed on the tensile adhesive layer 31. The self-adhesive adhesive 32 is disposed on the side of the tensile adhesive layer 31 away from the substrate layer 1, and an adhesive post 33 is provided on the side of the self-adhesive adhesive 32 close to the tensile adhesive layer 31 at a position corresponding to the groove 34.

[0028] In this configuration, the tensile adhesive layer 31 is positioned on the side of the substrate layer 1 away from the ink layer 2. It is typically made of a high-strength polymer material, possessing excellent tensile strength and flexibility. The tensile adhesive layer 31 effectively resists the tensile forces that the label may experience during use, preventing the label from detaching from the substrate. The tensile adhesive layer 31 provides a stable physical foundation for the entire label film, ensuring that the label maintains good adhesion performance in various environments. The flexibility of the tensile adhesive layer 31 allows it to adapt to surfaces of different shapes and roughness, ensuring that the label adheres firmly to various substrates. The self-adhesive adhesive 32 is positioned on the side of the tensile adhesive layer 31 away from the substrate layer 1, and is typically made of pressure-sensitive adhesive (such as acrylic). Made of esters, rubbers, etc., it has good initial tack and holding power. The self-adhesive adhesive 32 can achieve rapid bonding in a short time, is easy to operate, and is suitable for large-scale production. The adhesive post 33 is set on the side of the self-adhesive adhesive 32 near the tensile bonding layer 31, corresponding to the groove 34 on the tensile bonding layer 31. The adhesive post 33 is usually made of high-strength adhesive material, which can further enhance the bonding performance. The adhesive post 33 can further enhance the bonding strength between the self-adhesive adhesive 32 and the tensile bonding layer 31, ensuring that the label will not loosen due to external force during use. The corresponding design of the adhesive post 33 and the groove 34 can ensure the precise alignment of the bonding layer 3, improve production efficiency and product quality.

[0029] In some embodiments, please refer to the following: Figures 1 to 4 The ink layer 2 has a varnish coating 4 on the side away from the substrate layer 1. The varnish coating 4 is made of synthetic resin material, and the substrate layer 1 is made of PVC product shrinkage adjustment material.

[0030] This configuration allows the varnish coating 4 to significantly enhance the gloss of the label surface, making the label more visually appealing. The varnish coating 4 effectively prevents the ink layer 2 from fading, oxidizing, and being corroded by external chemicals, extending the label's lifespan. The protective layer formed after the varnish coating 4 cures has high hardness and abrasion resistance, resisting scratches and wear during daily use. The PVC substrate layer 1 is made using product shrinkage adjustment technology, possessing good flexibility to adapt to surfaces of different shapes and sizes. PVC material has excellent chemical corrosion resistance, resisting the erosion of various chemicals and suitable for various application scenarios. Layer 1 can form good adhesion with ink layer 2 and varnish coating 4, ensuring the stability and durability of the label. PVC is a relatively economical material that can reduce production costs while ensuring performance. The combined design of varnish coating 4 and PVC substrate layer 1 not only improves the appearance and gloss of the label, but also enhances its abrasion resistance, weather resistance and chemical corrosion resistance. By enhancing the abrasion resistance and weather resistance of the label, the service life of the label in outdoor environments or complex usage scenarios is significantly extended. The use of synthetic resin materials for varnish coating 4 and PVC substrate layer 1 meets modern environmental protection and safety standards, reducing the impact on the environment and human health.

[0031] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
