[0001] The utility model relates to the technical field of labels, and particularly relates to a degradable film label. Background Art

[0002] Most of the labels referred to in the printing industry are printed materials used to label the relevant descriptions of their own products, and most of them exist in the form of self-adhesive on the back. In order to achieve waterproof, oil-proof or other performance requirements, most labels use plastics as materials. While bringing more convenience to people's lives, they also have a certain impact on the environment. Under the general trend of global plastic bans and restrictions, as disposable labels, the demand for plastic-free, environmentally friendly and recyclable labels has increased significantly.

[0003] Most of the currently used plastic labels become solid waste after completing their functional purposes. Due to the low recycling rate, most of them are piled up outdoors. Since they are difficult to degrade naturally, they accumulate more and more in the natural environment, bringing uncontrollable pollution to the social environment and having poor environmental protection.

[0004] In addition, there are many goods in a general warehouse, and ordinary labels do not have the property of emitting light. When specific goods are needed at night, it is time-consuming and laborious due to insufficient light. Content of the Utility Model

[0005] In order to solve the deficiencies in the above-mentioned prior art, the utility model provides a degradable film label.

[0006] In order to achieve the above technical effects, the utility model adopts the following scheme:

[0007] A degradable film label includes a degradable substrate layer, an information paper layer, a light-emitting film layer, a first waterproof layer and a second waterproof layer. The second waterproof layer is arranged at the lower end of the substrate layer, the information paper layer is arranged at the upper end of the substrate layer, the light-emitting film layer is arranged at the upper end of the information paper layer, and the light-emitting film layer is arranged in a "square" shape and surrounds the edge of the information paper layer. The first waterproof layer is arranged at the upper end of the light-emitting film layer.

[0008] In a preferred technical solution, both the first waterproof layer and the second waterproof layer are BOPP degradable films.

[0009] In a preferred technical solution, a scratch-resistant layer is arranged at the upper end of the first waterproof layer, and the scratch-resistant layer is a water-based acrylic resin layer.

[0010] In a preferred technical solution, the substrate layer is a kraft paper layer.

[0011] In a preferred technical solution, the information paper layer is a virgin pulp paper layer.

[0012] Compared with the prior art, the beneficial effects are as follows:

[0013] The utility model has a simple structure and is convenient to use. It adopts degradable materials and can be naturally degraded, which is green and environmentally friendly. In addition, the light-emitting film layer will emit light under the irradiation of light. The label is used for specific goods, so that the required goods can be accurately found by irradiating with light at night, and different light-emitting film layers can emit different colors of light to mark different goods.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0018] A degradable film label includes a degradable base material layer 1, an information paper layer 2, a light-emitting film layer 3, a first waterproof layer 4 and a second waterproof layer 5. The second waterproof layer 5 is provided at the lower end of the base material layer 1, the information paper layer 2 is provided at the upper end of the base material layer 1, the light-emitting film layer 3 is provided at the upper end of the information paper layer 2, and the light-emitting film layer 3 is arranged in a "mouth" shape and is arranged around the edge of the information paper layer 2. The first waterproof layer 4 is provided at the upper end of the light-emitting film layer 3.

[0019] In a preferred technical solution, both the first waterproof layer 4 and the second waterproof layer are BOPP degradable films.

[0020] In a preferred technical solution, a scratch-resistant layer 6 is provided at the upper end of the first waterproof layer 4, and the scratch-resistant layer 6 is a water-based acrylic resin layer.

[0021] Water-based acrylic resin will gradually degrade under certain environmental conditions such as temperature, humidity, and light, or biodegradation can be accelerated by introducing a polylactic acid-polyvinyl alcohol block copolymer.

[0022] In a preferred technical solution, the base material layer 1 is a kraft paper layer.

[0023] Kraft paper is made from natural fibers and can be completely decomposed into carbon dioxide and water in the natural environment through the action of microorganisms, making it environmentally friendly. In addition, kraft paper has good tear resistance and water resistance.

[0024] In a preferred embodiment, the information paper layer 2 is a virgin pulp paper layer.

[0025] Virgin pulp paper is mainly made of bamboo pulp or wood pulp. These fibers can be decomposed by microorganisms in the natural environment and eventually converted into carbon dioxide and water.

[0026] The biodegradable light-emitting film layer is prepared using existing technologies, such as the film made from the light-emitting material disclosed in patent CN110183699A, "A Flexible Light-Emitting Material and Its Preparation Method and Application." Specifically, a water-soluble polymer is dissolved in a suspension of ultrasonically treated cellulose nanocrystals or surface-functionalized modified cellulose nanocrystals to obtain a mixture. The mixture is then ultrasonically treated again and allowed to stand until no bubbles remain. A substrate is then vertically immersed in the mixture and allowed to stand for 3-5 days at a temperature of 25-35°C and a humidity of 20-50%, forming a film on the substrate to obtain the flexible light-emitting material. The obtained light-emitting material emits light under certain illumination, and materials emitting different colors of light can be obtained by adding different additives.
