Description

Technical Field

[0001] This utility model relates to the field of stretch films, specifically a high-barrier stretch film. Background Technology

[0002] High-barrier stretch film is a multi-layered film material that combines different materials through multi-layer co-extrusion technology to form a high-performance film with excellent barrier properties. It can effectively block the penetration of substances such as oxygen, water vapor, and oils, extending the shelf life of products. It also has good tensile properties and heat resistance. High-barrier stretch film is widely used in the food, pharmaceutical, cosmetic, and electronics industries to meet the packaging needs of different products.

[0003] High-barrier stretch film is widely used, but there is a substantial problem in its actual use: when used for product packaging, stretch film fails to provide effective anti-counterfeiting measures, thus reducing its practicality. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a high-barrier stretch film to solve the technical problem that when stretch film is used for product packaging, it fails to effectively provide sufficient anti-counterfeiting protection for the product.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-barrier stretch film, comprising a stretch film body, wherein the stretch film body comprises, from the inside out, an inner film, a base layer, a tensile layer, a fluorescent anti-counterfeiting layer, and an outer film, wherein the fluorescent anti-counterfeiting layer is at least one layer and has at least one color expression form.

[0006] By adopting the above technical solutions, the inner membrane and the base layer provide good basic support, the tensile layer enhances the mechanical strength of the stretch film, and the outer membrane, as the outermost layer, is in direct contact with the external environment and plays a protective role. In particular, the addition of the fluorescent anti-counterfeiting layer, which is at least one layer and has at least one color expression, adds anti-counterfeiting function to the stretch film and effectively prevents product counterfeiting and cross-selling.

[0007] Furthermore, the inner membrane, base layer, tensile layer, fluorescent anti-counterfeiting layer, and outer membrane are bonded together by an adhesive layer.

[0008] By adopting the above technical solution, a strong bond between the layers of the stretch film is ensured, which not only improves the overall structural stability of the stretch film, but also enhances its mechanical properties such as tear resistance and puncture resistance, making the stretch film more reliable in packaging, transportation and use.

[0009] Furthermore, the inner membrane and the base layer are both made of PP polypropylene, while the outer membrane and the tensile layer are made of PA nylon.

[0010] By adopting the above technical solution, the excellent physical properties and chemical stability of PP polypropylene are fully utilized. This allows the stretch film to maintain high strength while also possessing good flexibility and weather resistance, enabling it to adapt to various complex environmental conditions.

[0011] Furthermore, the fluorescent anti-counterfeiting layer is printed with an anti-counterfeiting pattern.

[0012] By adopting the above technical solutions, the stretch film not only has basic packaging functions, but also realizes anti-counterfeiting identification of products. The addition of anti-counterfeiting patterns provides consumers with an intuitive and easy-to-identify anti-counterfeiting method, effectively preventing the circulation of counterfeit and shoddy products.

[0013] Furthermore, the surface of the outer membrane is formed with a plurality of grooves in an equidistant rectangular array.

[0014] By adopting the above technical solution, not only is the surface area of ​​the outer film increased, but the grip and anti-slip performance of the stretch film are also improved. The presence of the groove increases the contact area between the fingers and the stretch film, increasing the friction and making it easier to grip and manipulate the stretch film.

[0015] In summary, the present invention has the following main advantages:

[0016] 1. This utility model provides an effective anti-counterfeiting measure for products by setting a fluorescent anti-counterfeiting layer. Through specific fluorescent effects and color expression, the fluorescent anti-counterfeiting layer can make genuine products and counterfeit products obviously different in appearance, thereby helping consumers and users to quickly and accurately identify the authenticity of products. This anti-counterfeiting method has the characteristics of being intuitive and easy to identify, which helps to improve market transparency and consumer trust. At the same time, the at least one layer structure and at least one color expression of the fluorescent anti-counterfeiting layer provide greater flexibility for the anti-counterfeiting design of products. Enterprises can customize anti-counterfeiting layers with unique fluorescent effects and color expression according to their own needs and preferences, thereby enhancing the personalization and exclusivity of products.

[0017] 2. This utility model provides an intuitive anti-counterfeiting method for stretch film through the printing of anti-counterfeiting patterns. Consumers or users can quickly identify the authenticity of products by observing the anti-counterfeiting patterns, effectively preventing the circulation of counterfeit and shoddy products. This intuitive anti-counterfeiting method is simple and easy to implement, requiring no professional equipment or technology, thus improving the popularity and effectiveness of anti-counterfeiting. At the same time, the customized design of anti-counterfeiting patterns enhances the personalization and exclusivity of stretch film. Enterprises can print their own logos, brand logos, or specific patterns on the fluorescent anti-counterfeiting layer to form a unique anti-counterfeiting mark. This customized design not only enhances the brand image of the product but also increases consumers' trust and loyalty to the product. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0022] Example 1:

[0023] A high-barrier stretch film, such as Figure 1-2 As shown, the stretch film body 1 includes, from the inside out, an inner film 101, a base layer 103, a tensile layer 104, a fluorescent anti-counterfeiting layer 105, and an outer film 102. The fluorescent anti-counterfeiting layer 105 is at least one layer and has at least one color expression. The inner film 101 and the base layer 103 provide good basic support, the tensile layer 104 enhances the mechanical strength of the stretch film, and the outer film 102, as the outermost layer, is in direct contact with the external environment and plays a protective role. In particular, the addition of the fluorescent anti-counterfeiting layer 105, which is at least one layer and has at least one color expression, adds anti-counterfeiting function to the stretch film, effectively preventing product counterfeiting and cross-selling. At the same time, the fluorescent anti-counterfeiting layer 105 not only improves the practicality of the stretch film but also increases its market competitiveness. In the current market, anti-counterfeiting function has become one of the important factors for consumers when choosing products.

[0024] See Figure 1 , Figure 2 The inner film 101, base layer 103, tensile layer 104, fluorescent anti-counterfeiting layer 105, and outer film 102 are bonded together by an adhesive layer 106, ensuring a strong bond between the layers of the stretch film. This not only improves the overall structural stability of the stretch film but also enhances its mechanical properties such as tear resistance and puncture resistance, making the stretch film more reliable during packaging, transportation, and use. At the same time, the use of adhesive layer 106 simplifies the production process of the stretch film, making the bonding between the layers simpler and more efficient.

[0025] See Figure 1 , Figure 2The inner membrane 101 and the base layer 103 are both made of PP polypropylene, while the outer membrane 102 and the tensile layer 104 are made of PA nylon. This fully utilizes the excellent physical properties and chemical stability of PP polypropylene, which allows the stretch film to maintain high strength while also possessing good flexibility and weather resistance, enabling it to adapt to various complex environmental conditions. At the same time, the selection of PA nylon as the material for the outer membrane 102 and the tensile layer 104 further enhances the mechanical strength and wear resistance of the stretch film. As a high-performance engineering plastic, PA nylon has excellent mechanical properties and heat resistance, and can withstand greater tensile and compressive forces, effectively preventing damage to the stretch film during packaging and transportation. This material selection not only improves the service life of the stretch film but also reduces the risk of product loss due to damage.

[0026] Example 2:

[0027] See Figure 1 , Figure 2 The fluorescent anti-counterfeiting layer 105 is printed with anti-counterfeiting patterns, enabling the stretch film to not only perform basic packaging functions but also achieve product anti-counterfeiting identification. The addition of anti-counterfeiting patterns provides consumers with an intuitive and easy-to-identify anti-counterfeiting method, effectively preventing the circulation of counterfeit and shoddy products. At the same time, the design of anti-counterfeiting patterns can also be customized according to the actual needs of customers, such as adding company logos, product serial numbers, and other information, further enhancing the personalization and exclusivity of the stretch film. This customized design not only enhances the brand image of the product but also increases consumers' trust and satisfaction with the product.

[0028] See Figure 1 , Figure 2 The outer membrane 102 has a number of grooves formed by an equidistant rectangular array on its surface. This not only increases the surface area of ​​the outer membrane 102, but also improves the grip and anti-slip performance of the stretch membrane. The presence of the grooves increases the contact area between the fingers and the stretch membrane, increasing the friction and making it easier to grip and manipulate the stretch membrane. At the same time, the groove design also enhances the aesthetics and practicality of the stretch membrane. The grooves in the equidistant rectangular array form a regular pattern, making the stretch membrane more attractive in appearance.

[0029] The implementation principle of this embodiment is as follows: The stretch film body 1 achieves high barrier and anti-counterfeiting functions through a multi-layer structure design. The inner film 101 and the base layer 103 are made of PP polypropylene material, providing good basic performance; the tensile layer 104 and the outer film 102 are made of PA nylon material, which enhances the strength and wear resistance of the stretch film. In particular, a fluorescent anti-counterfeiting layer 105 is set between the tensile layer 104 and the outer film 102. This layer is at least one layer structure and has at least one color expression form. It can also be printed with anti-counterfeiting patterns to realize the anti-counterfeiting identification of the product. The layers are tightly bonded together by the adhesive layer 106 to ensure the stability of the overall structure. The surface of the outer film 102 is also designed with grooves in an equidistant rectangular array to improve the grip and anti-slip performance. Thus, the high-barrier stretch film of this embodiment not only has excellent barrier performance, but also achieves effective anti-counterfeiting function.
