[0024] The present embodiment is a water-soluble and easily degradable label, and its structural schematic view is as shown in Figures 1-4As shown, the label includes a printing layer 1, the bottom of the printing layer 1 is provided with a support layer 3, the bottom of the support layer 3 is provided with a permeation prevention layer 4, the bottom of the permeation prevention layer 4 is provided with a buffer layer 5, the bottom of the buffer layer 5 is provided with an adhesive layer 6, and the outer side of the top of the printing layer 1 is provided with a protective layer 2;

[0025] The material of the printing layer 1 is water-soluble coated paper, which is a special paper coated with water-soluble materials on the surface. The coating is usually composed of substances with water-soluble or degradable properties, which can quickly dissolve or decompose after contacting water or moisture, thereby avoiding the environmental burden that traditional paper may bring. The main advantage of water-soluble coated paper is its good environmental characteristics, making it particularly suitable for applications that require short-term use, temporary packaging, or environmentally friendly destruction.

[0026] The material of the protective layer 2 is polycaprolactone film, which is a biodegradable plastic with good flexibility and water resistance. By modifying the polycaprolactone film, its transparency can be improved, making it suitable for packaging applications that require high transparency and water resistance. This allows the protective layer 2 to protect the printing layer 1 from accidental contact with liquids, preventing changes to the surface data and improving the protective performance of the device.

[0027] The material of the support layer 3 is polyvinyl alcohol-based soluble paper. Polyvinyl alcohol is a common water-soluble polymer widely used in the manufacture of soluble paper. It has a strong film structure, providing good support and strength. It can meet the water-soluble requirements while maintaining support and tear resistance, providing support for the printing layer 1 and preventing deformation due to environmental moisture.

[0028] The material of the permeation prevention layer 4 is polylactic acid film, which is a biobased plastic made from renewable resources. It has good biodegradability and can improve its moisture resistance and permeation prevention performance through compounding or coating treatment, thereby improving the moisture resistance of the label.

[0029] The material of the buffer layer 5 is starch-based foam, which is a biodegradable foam material made by combining natural starch with plasticizers and foaming agents. It has excellent biodegradability and buffering performance.

[0030] The material of the adhesive layer 6 is starch-based adhesive, which is made from corn starch, potato starch, or other plant starch as the main raw material. It is suitable for bonding paper, paperboard, and textiles.

[0031] The inside of the support layer 3 is provided with a plurality of longitudinal support strips 31, and the inside of the support layer 3 is also provided with a plurality of transverse support strips 32, which are located at the bottom of the longitudinal support strips 31, and the materials of the longitudinal support strips 31 and the transverse support strips 32 are carboxymethyl cellulose-based soluble paper, carboxymethyl cellulose is a water-soluble derivative of cellulose, has strong water solubility, and can maintain a certain structural strength in a humid environment, the support performance of the carboxymethyl cellulose-based soluble paper depends on the fiber ratio and the use of the water-soluble coating, which can provide appropriate support and quickly degrade after contacting water, meeting the environmental protection requirements;

[0032] The inside of the anti-permeation layer 4 and the buffer layer 5 is provided with a plurality of vertical connecting columns 7, the top of the vertical connecting column 7 is fixedly connected with the support layer 3, the bottom of the vertical connecting column 7 is fixedly connected with the adhesive layer 6, and the material of the vertical connecting column 7 is natural rubber, which is a biological material extracted from rubber trees, has excellent elasticity and adhesion, and can make the connection between the support layer 3 and the adhesive layer 6 more stable and prevent faulting;

[0033] The setting of the protective layer 2 can effectively prevent the display content of the printing layer 1 from being damaged due to water contact in a humid environment, and can effectively absorb impact force when the label is subjected to external force impact or friction, avoid faulting or damage of the label, enhance the pressure resistance and tear resistance of the label in the daily use process, thereby effectively prolonging the service life of the label and improving the market competitiveness thereof, can provide more reliable protection while ensuring environmental protection requirements, avoid label failure caused by external environment or physical damage, and meet the dual requirements of functionality and environmental protection in the modern packaging and label industry.

[0034] All the technical features in the embodiment can be freely combined according to actual needs.

[0035] The above embodiment is a preferred implementation scheme of the utility model, in addition to this, the utility model can be realized in other ways, and any obvious replacement without departing from the technical scheme concept is within the protection scope of the utility model.
