[0028] The utility model will be further described in detail below in combination with the drawings.

[0030] The working principle of the moisture-proof packaging structure of the pearl cotton product is as follows:
[0031] The moisture-proof packaging structure of the pearl cotton product realizes the functions of moisture-proof, moisture-absorbing, odor removal and protection of the pearl cotton product through the synergistic effect of the layers. First, the moisture-proof barrier layer 3 serves as the first line of defense, and uses the composite structure of biaxially oriented polypropylene film 301 and aluminium foil 302 to block the entry of external moisture, preventing the penetration of moisture in a high-humidity environment into the packaging bag, thereby creating a relatively dry environment inside. In the case where the moisture-proof barrier layer 3 fails to completely block the entry of moisture, the silica gel desiccant particles in the moisture-absorbing and drying layer 5 will play a role, which will absorb the trace amount of moisture entering the packaging bag through physical adsorption principle, further reducing the humidity inside the packaging, ensuring that the pearl cotton product is in a dry state. At the same time, the activated carbon fiber cloth used in the odor removal layer 6 can continuously adsorb odor molecules that may be generated inside the packaging, keeping the air inside fresh. The pearl cotton buffer layer 4 not only provides buffering protection, but also provides certain support and protection to the moisture-absorbing and drying layer 5, preventing it from being damaged by external force, thereby protecting the pearl cotton product from moisture and odor, and maintaining its good performance state.
[0032] The functions of the structures in the scheme are described in detail as follows:
[0033] Moisture-proof barrier layer 3: made of biaxially oriented polypropylene film 301 and aluminum foil 302, biaxially oriented polypropylene film 301 is located on the outside, has good flexibility, tensile strength and wear resistance and other mechanical properties, plays a protective role for the internal aluminum foil layer and provides certain physical protection; aluminum foil 302 has very low water vapor transmission rate, can effectively block the intrusion of external water vapor, is the key structure of moisture-proof, the moisture-proof barrier layer 3 after compounding provides a reliable moisture-proof foundation for the packaging bag, ensures the dry and stable environment inside the packaging, and resists the humid environment for the pearl cotton product and the packaged product. The thickness is between 0.05-0.15mm, which can ensure good moisture-proof effect, and will not make the packaging bag too thick and heavy.
[0034] Pearl cotton buffer layer 4: on the one hand, it plays a buffering and shock-absorbing role for the packaged product during transportation and storage, preventing the product from being damaged due to collision and vibration; on the other hand, it is located between the moisture-proof barrier layer 3 and the moisture-absorbing and drying layer 5, supporting and protecting the internal moisture-absorbing and drying layer 5, avoiding damage due to external force pressing and friction, and also helping to maintain the relative position stability of each functional layer, ensuring the integrity and functionality of the whole packaging structure.
[0035] Moisture-absorbing and drying layer 5: including non-woven fabric outer layer, the non-woven fabric outer layer plays a role in containing and fixing the desiccant particles, the internally filled silica gel desiccant particles have rich pore structure and strong moisture absorption capacity, capturing water vapor molecules in the packaging bag by physical adsorption, absorbing and storing the trace of water vapor that may enter the packaging interior, thereby reducing the humidity in the packaging, even when the moisture-proof barrier layer 3 has a small gap or is in a high humidity environment for a long time, it can ensure that the pearl cotton product will not be damp, enhancing the insurance factor of moisture-proof, and maintaining the dry state and performance stability of the pearl cotton product. The particle size of the desiccant particles is 2-5mm, and the distribution density is 0.5-1g / cm 2 , such parameter settings ensure the efficiency and stability of the moisture absorption effect.
[0036] Odor-removing layer 6: made of activated carbon fiber cloth, which has a large specific surface area and rich microporous structure, can capture and adsorb odor molecules generated in the packaging by physical adsorption, such as residual odor in the production process of pearl cotton product and odor emitted by the packaging material itself, thereby keeping the air in the packaging fresh.
[0037] Cover 2: the material of cover 2 is the same as that of moisture-proof barrier layer 3, which ensures the consistency of the moisture-proof performance of the whole packaging bag, and the inner side of the magic tape hair surface 7 cooperates with the magic tape hook surface 8 on the packaging bag main body 1, which is convenient for sealing and opening the packaging bag, and facilitates the storage and retrieval of the product, and can quickly and effectively close the packaging bag during multiple uses.
[0038] The above has described the utility model and its implementation mode, which is not restrictive, and the drawings only show one of the implementation modes of the utility model, and the actual structure is not limited thereto. In summary, if a person skilled in the art is inspired thereby, without departing from the creative purpose of the utility model, similar structural modes and embodiments are not creatively designed, which should belong to the protection scope of the utility model.
