Description

Technical Field

[0001] This utility model relates to the field of self-adhesive label technology, and in particular to a transparent and biodegradable self-adhesive label. Background Technology

[0002] Self-adhesive labels have advantages over traditional labels, such as no need for glue, paste, or water, no pollution, and saving labeling time. They have a wide range of applications and are convenient and quick to use.

[0003] Dry adhesive labels are convenient and quick to use, but they are not easy to remove after being pasted. For example, if the wrong label is pasted during production and packaging, or if the user wants to remove the label for aesthetic or other reasons, the label cannot be completely and quickly torn off, and there is often label paper or adhesive residue, which is neither aesthetically pleasing nor convenient.

[0004] An existing patent (publication number: CN206672521U) discloses a self-adhesive label. The utility model provides a self-adhesive label that, when normally pasted, removes the release layer and pastes the label in the desired position; when the label is pasted incorrectly and needs to be torn off and re-pasted, or when the product user wants to remove the label, the label layer and the first adhesive layer are torn off, leaving the release layer in place. The release layer is a transparent film that does not affect the appearance or use of the product.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, most existing self-adhesive labels use non-degradable plastic materials as the base material, such as polyvinyl chloride and polyester. These materials are difficult to decompose in the natural environment, and long-term accumulation will cause serious environmental pollution. Furthermore, the transparency of some traditional self-adhesive labels cannot meet the requirements of some application scenarios with high label appearance requirements, such as packaging for high-end cosmetics and electronic products. Low transparency will affect the display effect of the product and reduce its attractiveness.

[0006] To address this, a transparent, biodegradable self-adhesive label is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a transparent and biodegradable self-adhesive label, which solves the problem that most existing self-adhesive labels use non-degradable plastic materials as the base material, such as polyvinyl chloride and polyester. These materials are difficult to decompose in the natural environment, and long-term accumulation will cause serious pollution to the environment. In addition, the transparency of some traditional self-adhesive labels cannot meet the requirements of some application scenarios with high label appearance requirements, such as high-end cosmetics and electronic product packaging. Low transparency will affect the display effect of the product and reduce the product's attractiveness.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a transparent biodegradable self-adhesive label, comprising a self-adhesive label body, the self-adhesive label comprising a transparent surface layer, a printing layer disposed at the bottom of the transparent surface layer, a substrate layer disposed at the bottom of the printing layer, and an adhesive layer disposed at the bottom of the substrate layer.

[0009] Preferably, the transparent surface layer is composed of a biodegradable transparent bio-based polymer film and is adhered to the top of the printed layer.

[0010] Preferably, the printing layer is printed using environmentally friendly water-based ink.

[0011] Preferably, the substrate layer is composed of a transparent TPU film.

[0012] Preferably, a barrier layer is provided at the top of the printed layer and at the bottom of the substrate layer, and the barrier layer is connected to the transparent surface layer and the adhesive layer respectively on the side closer to them.

[0013] Preferably, the barrier layer is made of transparent resin adhesive and is uniformly coated on one side close to the printed layer and the substrate layer.

[0014] Preferably, the adhesive layer is composed of a biodegradable water-based adhesive layer and is uniformly coated on the bottom of the barrier layer.

[0015] Preferably, a protective layer is provided at the bottom of the adhesive layer, and the protective layer is composed of release paper.

[0016] Preferably, the transparent surface layer, the printed layer, the substrate layer, the barrier layer, and the adhesive layer are all connected by hot-pressing composite.

[0017] Preferably, the degradable transparent bio-based polymer film is any one of polylactic acid film, polyhydroxyalkanoate film, or polybutylene succinate film.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This application uses a biodegradable material to make the self-adhesive label body, which can gradually decompose in the natural environment after being discarded, reducing environmental pollution, meeting environmental protection requirements, and contributing to sustainable development.

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.

[0027] Please see Figure 1-4 The present invention provides the following technical solution:

[0028] A transparent biodegradable self-adhesive label includes a self-adhesive label body 1, the self-adhesive label body 1 includes a transparent surface layer 2, a printing layer 3 is disposed at the bottom of the transparent surface layer 2, a substrate layer 4 is disposed at the bottom of the printing layer 3, and an adhesive layer 5 is disposed at the bottom of the substrate layer 4.

[0029] In this embodiment: through the design of the multi-layer structure of the self-adhesive label body 1, and through the combination of different functional layers, the self-adhesive label body 1 can not only have the function of pasting, but also better meet various usage needs. The transparent surface layer 2 provides a good appearance display effect, the printing layer 3 can realize the clear presentation of information, the substrate layer 4 ensures the overall strength and stability of the self-adhesive label body 1, and the adhesive layer 5 ensures that the self-adhesive label body 1 can be firmly pasted on the surface of the object. The synergistic effect of each layer improves the comprehensive performance of the self-adhesive label body 1.

[0030] Specifically, such as Figure 2 As shown, the transparent surface layer 2 is composed of a biodegradable transparent bio-based polymer film and is adhered to the top of the printed layer 3.

[0031] Specifically, such as Figure 2 As shown, printing layer 3 is printed using environmentally friendly water-based ink.

[0032] Specifically, such as Figure 2 As shown, substrate layer 4 is composed of a transparent TPU film.

[0033] In this embodiment: the transparent surface layer 2 is made of a biodegradable transparent bio-based polymer film, which has good biodegradability and can degrade quickly in the natural environment, meeting environmental protection requirements. At the same time, its transparency can meet the application scenarios with high requirements for the appearance of the self-adhesive label body 1, allowing the appearance of the affixed object to be better displayed; the printing layer 3 is printed with environmentally friendly water-based ink, which does not contain organic solvents, has low volatile organic compound emissions, and is harmless to the environment and human health, making it more environmentally friendly; the substrate layer 4 is made of TPU transparent film, which not only supports the printing layer 3, but also further enhances the environmental performance of the self-adhesive label body 1.

[0034] Specifically, such as Figure 3 As shown, a barrier layer 6 is provided on the top of the printed layer 3 and the bottom of the substrate layer 4, and the barrier layer 6 is connected to the transparent surface layer 2 and the adhesive layer 5 on the side closer to them respectively.

[0035] Specifically, such as Figure 3 As shown, the barrier layer 6 is made of transparent resin adhesive and is uniformly coated on the side close to the printed layer 3 and the substrate layer 4.

[0036] In this embodiment, the barrier layer 6 effectively prevents the ink of the printing layer 3 from interpenetrating and chemically reacting with the transparent surface layer 2 and the adhesive layer 5, protecting the integrity and clarity of the printed pattern and extending the service life of the self-adhesive label body 1. At the same time, the barrier layer 6 can also play a certain role in moisture-proofing, waterproofing, and oil-proofing, improving the stability and adaptability of the self-adhesive label body 1 under different environmental conditions.

[0037] Specifically, such as Figure 2 As shown, the adhesive layer 5 is composed of a biodegradable water-based adhesive layer and is uniformly coated on the bottom of the barrier layer 6.

[0038] Specifically, such as Figure 2 As shown, a protective layer 7 is provided at the bottom of the adhesive layer 5, and the protective layer 7 is made of release paper.

[0039] In this embodiment: the adhesive layer 5 is made of a biodegradable water-based adhesive layer, which has good adhesion and biodegradability. While ensuring that the self-adhesive label body 1 can be firmly pasted on the surface of the object, it reduces environmental pollution. The protective layer 7 at the bottom of the adhesive layer 5 is made of release paper, which can effectively protect the adhesive layer 5 from contamination and damage when not in use, and ensure that the adhesion and performance of the adhesive layer 5 are not affected.

[0040] Specifically, such as Figure 2 As shown, the transparent surface layer 2, the printed layer 3, the substrate layer 4, the barrier layer 6, and the adhesive layer 5 are all connected by hot pressing.

[0041] Specifically, such as Figure 2 As shown, the degradable transparent bio-based polymer film is any one of polylactic acid film, polyhydroxyalkanoate film, or polybutylene succinate film.

[0042] In this embodiment, the transparent surface layer, printing layer 3, substrate layer 4, barrier layer 6, and adhesive layer 5 are connected by hot-pressing. This connection method enables a tight and firm bond between the layers, improving the overall structural strength and stability of the self-adhesive label body 1 and preventing delamination and peeling between the layers. Several optional materials for biodegradable transparent bio-based polymer films, such as polylactic acid film, polyhydroxyalkanoate film, or polybutylene succinate film, are available. These materials each have advantages in terms of biodegradability, transparency, and mechanical properties, providing more options for the selection of materials for the transparent surface layer 2.

[0043] Working principle: When using the self-adhesive label body 1, the protective layer 7 can be peeled off, and the self-adhesive label body 1 can be adhered to the object through the adhesive layer 5. The transparent surface layer 2 provides a good appearance display effect, the printing layer 3 enables clear presentation of information, the substrate layer 4 ensures the overall strength and stability of the self-adhesive label body 1, and the adhesive layer 5 ensures that the self-adhesive label body 1 can be firmly pasted on the object surface. The synergistic effect of each layer improves the overall performance of the self-adhesive label body 1. Furthermore, the barrier layer 6 protects the integrity and clarity of the printed pattern and extends the service life of the self-adhesive label body 1. At the same time, the barrier layer 6 can also play a certain role in moisture-proof, waterproof, and oil-proof, improving the stability and adaptability of the self-adhesive label body 1 under different environmental conditions.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
