Technical Field

[0001] The utility model relates to the technical field of plastic films, in particular to a moisture-absorbing and moisture-proof plastic film. Background Art

[0002] For example, the utility model with application number 202223332535.8 discloses a plastic film that is moisture-proof and hygroscopic. The external moisture is absorbed by an external plastic layer, an internal moisture-proof layer, an upper moisture-proof layer, a lower moisture-proof layer, a built-in groove and a water-absorbing material placed in the built-in groove, so as to ensure that the external plastic layer and the plastic film base layer, as well as the internal plastic layer and the plastic film base layer have high waterproof performance. At the same time, the built-in groove is set to a trapezoidal shape that is wide at the top and narrow at the bottom to avoid damage to the membrane structure caused by the internal water-absorbing material when it expands when absorbing external moisture.

[0003] Similar to the above application, there are still some shortcomings:

[0004] The moisture-proof and hygroscopic plastic film has a high waterproof performance, but the moisture-proof and hygroscopic plastic film only has a certain waterproof performance, but does not have good air permeability, can only absorb moisture, and cannot evacuate stagnant moisture, which will increase the quality of the plastic film and cause the plastic film to be easily damaged.

[0005] For this reason, a hygroscopic and moisture-proof plastic film is designed to optimize the above-mentioned problems. Utility Model Content

[0006] The main purpose of the utility model is to provide a moisture-absorbing and moisture-proof plastic film to solve the related technical problems raised in the above background technology.

[0007] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0008] A moisture-absorbing and moisture-proof plastic film comprises a base layer, a fixed layer is arranged on the top of the base layer, adsorption holes are evenly opened on the top of the fixed layer, a moisture-absorbing layer is fixed on the top of the fixed layer, a conductive layer is fixed on the top of the moisture-absorbing layer, a breathable layer is arranged on the top of the conductive layer, evacuation holes are evenly opened on the bottom of the breathable layer, air holes are evenly opened on the top of the air-permeable layer, and through holes are fixed between the air holes and the evacuation holes.

[0009] Preferably, a connecting layer is fixed to one end of the base layer, grooves are provided on both sides of the connecting layer, and fixing holes are evenly provided on the top of the connecting layer.

[0010] Preferably, a reinforcement layer is fixed on the top of the conductive layer, and reinforcement wires are evenly arranged inside the reinforcement layer.

[0013] Preferably, an antibacterial layer is provided at the bottom of the base layer, and the antibacterial layer is a zinc oxide antibacterial layer.

[0014] The beneficial effects of the utility model are:

The protective layer blocks external moisture from entering the base layer and articles thereon, and moisture on the articles enters the moisture-absorbing layer and the conductive layer through the adsorption holes, and the internal moisture is absorbed by the conductive layer, and the moisture evaporates outwards and flows to the evacuation holes, enters the through holes, and then flows outwards from the vent hole and evaporates, while external moisture that enters the vent hole will be retained at the adsorption block in the vent hole and cannot directly enter the bottom, so that the moisture-absorbing and moisture-proof plastic film can be kept breathable while being moisture-absorbing and moisture-proof, and the moisture on the articles can be absorbed and moisture-proof. The outflow and evaporation of water are promoted during the wetting process, and the problem that the weight of the hygroscopic moisture-proof plastic film increases after absorbing water, which causes the plastic film to be easily damaged, is avoided, thereby improving the practicality of the hygroscopic moisture-proof plastic film; through the coordinated use of the connecting layer, the fixing holes and the cutting grooves, the connecting layer can be torn along the direction of the laying of the fixing holes by utilizing the cutting grooves on both sides of the connecting layer, thereby achieving the purpose of facilitating the division of the hygroscopic moisture-proof plastic film, thereby facilitating the use of the staff; through the coordinated use of the reinforcing wire and the reinforcing layer, the reinforcing layer and the reinforcing wire enhance the connection force between the breathable layer and the conductive layer, thereby improving the overall firmness of the hygroscopic moisture-proof plastic film, thereby enhancing the firmness of the hygroscopic moisture-proof plastic bag.
