Description

Technical Field

[0001] This application relates to the field of composite labels, and more particularly to an oil- and water-resistant composite label. Background Technology

[0002] Self-adhesive labels offer advantages over traditional labels, including no need for glue, paste, or water, zero pollution, and time-saving application. They are widely applicable and convenient. Self-adhesive labels are a composite material made of paper, film, or other special materials as the face stock, coated with adhesive on the back, and with silicone-coated release paper as the backing. After printing, die-cutting, and other processing, they become finished labels.

[0003] Publication No. CN 217709302 U discloses the structure of a high-performance oil-proof and waterproof label material, including a connecting adhesive layer, a hardening layer connected to the upper layer of the connecting adhesive layer, ... and an oil-proof layer and a waterproof membrane connected to the upper surface of the base layer, so that the device has a high-performance waterproof and oil-proof effect and is easy to use.

[0004] However, in actual use, although the label can be laminated to enhance its protective performance, it still has the problem of poor waterproof and oil-proof effects. In addition, the existing composite label base layer and label layer are made of ordinary paper, which has low strength, poor abrasion resistance and tear resistance, and is easily damaged. Utility Model Content

[0005] To address the issues that while lamination can enhance protective properties, it still results in poor waterproofing and oil resistance, and that existing composite labels, with their base and label layers made of ordinary paper, suffer from low strength, poor abrasion and tear resistance, and are easily damaged, this application provides an oil-proof and waterproof composite label.

[0006] The oil- and water-resistant composite label provided in this application adopts the following technical solution:

[0007] An oil- and water-resistant composite label includes a release paper body, a waste area, and a label body. The waste area is attached to the top of the release paper body, and the label body is embedded inside the waste area. Both the bottom surfaces of the waste area and the label body are coated with an adhesive layer. A base paper layer is fixedly disposed at the bottom of the release paper body, and a polyethylene film is integrally attached above the base paper layer. The top surface of the polyethylene film is coated with a silicone oil layer, and a base paper layer is fixedly disposed inside the label body.

[0008] By adopting the above technical solution, the polyethylene coating can give the base paper layer good waterproof and oil-proof properties, and the silicone oil has good slip and non-stick properties. This makes the release paper body coated with silicone oil less likely to stick to the label body when in contact, and can be easily peeled off.

[0009] Preferably, a resin layer is fixedly adhered to the bottom surface of the backing paper layer, and the resin layer is integrally connected to the backing paper layer by impregnation.

[0010] By adopting the above technical solution, the resin layer is impregnated at the bottom of the backing paper layer and bonded to it as a whole. The effect is to increase the strength and hardness of the backing paper layer, reduce the expansion and contraction of the backing paper layer, thereby effectively improving the service strength of the backing paper layer and preventing the backing paper layer from being accidentally torn and damaged.

[0011] Preferably, an upper film and a lower film are fixedly bonded to the top and bottom surfaces of the base paper layer, respectively.

[0012] By adopting the above technical solution, the upper film and the lower film encapsulate and combine the base paper layer, which can effectively improve the oil and water resistance of the base paper layer and effectively improve the protective performance of the label body.

[0013] Preferably, both the upper and lower films are made of thermoplastic TPE material.

[0014] By adopting the above technical solutions, thermoplastic TPE materials have better aging resistance, high temperature resistance, and corrosion resistance, and the encapsulation base paper layer can significantly improve the service life and application range of the label body.

[0015] Preferably, a fiber reinforcement layer is integrally fixed inside the base paper layer, and the fiber reinforcement layer is formed by adding glass fibers into the paper pulp of the base paper layer.

[0016] By adopting the above technical solution, during the production process of the base paper layer, glass fiber is added to the paper pulp of the base paper layer and mixed evenly to form a fiber reinforcement layer. The fiber reinforcement layer utilizes the strength of its natural material to enhance the strength and toughness of the base paper layer, making the label body more tear-resistant, thereby further improving the strength of the label body in use.

[0017] Preferably, a coating layer is integrally bonded between the base paper layer and the upper film, and the coating layer is formed by melt bonding of polypropylene material.

[0018] By adopting the above technical solution, polypropylene plastic particles are melted, cast, cooled and solidified to form a coating layer, which is then thermally laminated with the base paper layer to effectively protect the base paper layer, giving it stronger oil and water resistance and further improving the protective effect.

[0019] Preferably, both the waste area and the label body are bonded to the silicone oil layer of the release paper body via an adhesive layer.

[0020] By adopting the above technical solution, when using the label, the release paper body is bent so that the self-adhesive layer at the corner of the label body detaches from the release paper body and forms a curl, so that the label body can be peeled off and removed from the waste area for pasting.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. The use of upper and lower films enhances the service life and applicability of the base paper layer. The upper and lower films encapsulate and combine the base paper layer, which can effectively improve the oil and water resistance of the base paper layer and enhance the protective performance of the label body. Thermoplastic TPE material has better aging resistance, high temperature resistance, and corrosion resistance. Encapsulating the base paper layer can significantly improve the service life and applicability of the label body.

[0023] 2. Enhance the strength of the label body by using a fiber reinforcement layer. During the production of the base paper layer, glass fiber is added to the paper pulp of the base paper layer and mixed evenly to form a fiber reinforcement layer. The fiber reinforcement layer utilizes the strength of its natural material to enhance the strength and toughness of the base paper layer, making the label body more tear-resistant, thereby further improving the service strength of the label body.

[0024] 3. The strength of the backing paper layer is enhanced by the resin layer. The resin layer is impregnated at the bottom of the backing paper layer and bonded to it as a whole. Its effect is to increase the strength and hardness of the backing paper layer, reduce the expansion and contraction of the backing paper layer, and thus effectively improve the service strength of the backing paper layer and prevent the backing paper layer from being accidentally torn and damaged.

[0030] The following is in conjunction with the appendixFigures 1-4 This application will be described in further detail.

[0031] This application discloses an oil-proof and waterproof composite label.

[0032] Reference Figure 1 and Figure 4 An oil-proof and waterproof composite label includes a release paper body 1, a waste area 2, and a label body 3. The waste area 2 is attached to the top of the release paper body 1, and the label body 3 is embedded inside the waste area 2. Both the bottom surfaces of the waste area 2 and the label body 3 are coated with an adhesive layer 4. A base paper layer 101 is fixedly disposed at the bottom of the release paper body 1. A polyethylene film 102 is integrally attached above the base paper layer 101. The top surface of the polyethylene film 102 is coated with a silicone oil layer 103. A base paper layer 301 is fixedly disposed inside the label body 3. A resin layer 104 is fixedly attached to the bottom surface of the base paper layer 101. 104 is integrally connected to the backing paper layer 101 by impregnation. The polyethylene coating 102 gives the backing paper layer 101 good waterproof and oil-proof properties, and the silicone oil has good slip and non-stick properties. This makes it difficult for the release paper body 1 coated with silicone oil layer 103 to stick to the label body 3 when in contact, and it can be easily peeled off. The resin layer 104 is impregnated at the bottom of the backing paper layer 101 and bonded to it as a whole. Its effect is to increase the strength and hardness of the backing paper layer 101, reduce the expansion and contraction of the backing paper layer 101, and thus effectively improve the service strength of the backing paper layer 101 and prevent the backing paper layer 101 from being accidentally torn and damaged.

[0033] Reference Figure 3 The top and bottom surfaces of the base paper layer 301 are respectively fixedly bonded with an upper film 302 and a lower film 303. Both the upper film 302 and the lower film 303 are made of thermoplastic TPE material. The upper film 302 and the lower film 303 encapsulate and bond the base paper layer 301, which can effectively improve the oil and water resistance of the base paper layer 301 and effectively improve the protective performance of the label body 3. The thermoplastic TPE material has better aging resistance, high temperature resistance and corrosion resistance. Encapsulating the base paper layer 301 can greatly improve the service life and application range of the label body 3.

[0034] Reference Figure 3A fiber reinforcement layer 304 is integrally fixed inside the base paper layer 301. The fiber reinforcement layer 304 is formed by adding glass fiber to the paper pulp of the base paper layer 301. A coating layer 305 is integrally bonded between the base paper layer 301 and the upper film 302. The coating layer 305 is formed by melting and bonding polypropylene material. During the production of the base paper layer, glass fiber is added to the paper pulp of the base paper layer 301 and mixed evenly to form the fiber reinforcement layer 301. The fiber reinforcement layer 304 utilizes the strength of its natural material to enhance the strength and toughness of the base paper layer 301, making the label body 3 more tear-resistant, thereby further improving the service strength of the label body 3. After the polypropylene plastic particles are melted, they are cast, cooled and solidified to form the coating layer 305. After being thermally bonded with the base paper layer 301, it effectively protects the base paper layer 301, making the base paper layer 301 more oil-proof and waterproof, and further improving the protective effect.

[0035] Reference Figure 1 and Figure 2 The waste area 2 and the label body 3 are both bonded to the silicone oil layer 103 of the release paper body 1 by the self-adhesive layer 4. When in use, the release paper body 1 is bent so that the self-adhesive layer 4 at the corner of the label body 3 is detached from the release paper body 1 and forms a curl, so that the label body 3 can be peeled off and removed from the waste area 2 for pasting and use.

[0036] The implementation principle of the oil-proof and waterproof composite label in this application embodiment is as follows: First, the release paper body 1 is bent so that the self-adhesive layer 4 at the corner of the label body 3 detaches from the release paper body 1 and forms a curl. The label body 3 can then be peeled off and removed from the waste area 2 for pasting. The polyethylene coating 102 gives the base paper layer 101 good waterproof and oil-proof performance, and the silicone oil has good slip and anti-stick properties. This makes it difficult for the release paper body 1 coated with silicone oil layer 103 to stick to the label body 3 when in contact, and it can be easily peeled off. The resin layer 104 is impregnated at the bottom of the base paper layer 101 and bonded to it. Its effect is to increase the strength and hardness of the base paper layer 101, reduce the expansion and contraction of the base paper layer 101, and thus effectively improve the service strength of the base paper layer 101 and prevent the base paper layer 101 from being accidentally torn and damaged. The upper film 302 and the lower film 303 encapsulate the base paper layer 301. The combination effectively enhances the oil and water resistance of the base paper layer 301 and improves the protective performance of the label body 3. The thermoplastic TPE material has better aging resistance, high temperature resistance, and corrosion resistance. Encapsulating the base paper layer 301 can significantly improve the service life and application range of the label body 3. During the production process of the base paper layer, glass fiber is added to the paper pulp of the base paper layer 301 and mixed evenly to form a fiber reinforcement layer 301. The fiber reinforcement layer 304 utilizes the strength of its natural material to enhance the strength and toughness of the base paper layer 301, making the label body 3 more tear-resistant, thereby further improving the service strength of the label body 3. After the polypropylene plastic particles are melted, they are cast, cooled, and solidified to form a coating layer 305. After being thermally bonded with the base paper layer 301, it effectively protects the base paper layer 301, making the base paper layer 301 more oil and water resistant, and further improving the protective effect.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
