[0002] Fresh-keeping mats, also known as absorbent fresh-keeping mats or fresh-keeping mats, are materials that absorb moisture from the surface of food. By absorbing excess moisture, they help prevent food from spoiling and decaying, thereby extending the shelf life of food. Fresh-keeping mats are primarily composed of polymers, typically high-molecular compounds. These polymers come in the form of films or fibers. In recent years, technological advancements have led to the use of new materials, such as nanocellulose, in the manufacture of fresh-keeping mats, which offer improved biodegradability and antibacterial properties.

[0003] However, most fresh-keeping mats nowadays can only achieve the function of preservation, and do not have the function of buffering. As a result, they cannot resist external impact when preserving fresh food, which easily leads to the risk of breakage and damage of some fragile foods (such as eggs).

[0004] Therefore, it is necessary to design a fresh-keeping pad with dual functions of buffering and preserving to solve the above-mentioned problems. Utility Model Content

[0025] In this embodiment, the buffer layer 2 is made of pearl cotton, and a plurality of spheres 21 are provided on the buffer layer 2; the buffer layer 2 and the fresh-keeping layer 3 are bonded together by a second adhesive layer 6; due to the unique structure of the pearl cotton, which is composed of many small spheres 21, there are many connection points between these small spheres, making it not easily deformed under the action of external forces and able to control vibration well. At the same time, the gaps between the small spheres can block heat and sound, further enhancing its buffering effect, thereby achieving protection for fragile fresh food during transportation;

[0026] When producing pearl cotton and fresh-keeping pads, the main processes are as follows:

[0027] 1. Select the pearl cotton material that meets the requirements, and determine the density, color, thickness and other parameters of the pearl cotton according to the purpose and design requirements of the preservation pad.

[0028] 2. Use cutting machines, pressing machines and other equipment to cut the pearl cotton into the required shape and size, and perform necessary molding treatments such as embossing and embossing to enhance its aesthetics and practicality.

[0029] 3. Laminate the treated pearl cotton layer with the pearl cotton. This step is usually achieved by hot pressing, bonding, etc. to ensure that the layers are tightly combined to form an integral fresh-keeping mat.

[0032] When producing pearl cotton and fresh-keeping pads, the main processes are as follows:

[0033] 1. Select a polymer absorbent resin that has excellent water absorption performance, is environmentally friendly, and meets food safety standards; select a suitable base material such as non-woven fabric, paper, film, etc. according to the purpose and design requirements of the fresh-keeping mat.

[0034] 2. Dissolve or disperse the polymer water-absorbing resin in an appropriate solvent to form a uniform resin solution or suspension.

[0035] 3. Combined process

[0036] Coating method: The resin solution or suspension is evenly coated on the surface of the substrate, and then the resin is fixed on the substrate through drying or curing. This method is suitable for fresh-keeping mats that require a thin resin layer.

[0037] Lamination: A film or sheet containing resin is laminated to a substrate, and the resin layer and substrate are tightly bonded by heat pressing or bonding. This method is suitable for fresh-keeping mats that require a thicker resin layer or a specific structure.

[0038] Impregnation method: The substrate is completely or partially immersed in the resin solution, then removed and properly treated (such as drying and curing) to allow the resin to penetrate and fix into the substrate. This method is suitable for fresh-keeping mats that require the resin to be evenly distributed within the substrate.

[0039] 4. According to the type of resin and process requirements, the coated or laminated fresh-keeping mat is dried or cured to ensure that the resin is completely cured and fixed on the substrate.

[0040] 5. Cutting and packaging: Cut the processed fresh-keeping mats according to the specified size, and package and label them for storage and transportation.

[0041] In this embodiment, the leak-proof edge 5 is rolled with a fabric strip, and the inner wall of the leak-proof edge 5 and the fresh-keeping layer 3 are bonded together with a first adhesive layer 8; the leak-proof edge 5 can prevent blood from seeping out and contaminating the outer packaging after the fresh meat is wrapped with the fresh-keeping pad.

[0042] The working process of the utility model is as follows: in the production of the fresh-keeping pad with the dual functions of buffering and preserving, firstly, select the pearl cotton material that meets the requirements as the base material, such as non-woven fabric, paper, film, etc., determine the density, color, thickness and other parameters of the pearl cotton according to the purpose and design requirements of the fresh-keeping pad, and at the same time select a polymer water-absorbing resin with excellent water absorption performance, environmental protection and compliance with food safety standards; dissolve or disperse the polymer water-absorbing resin in an appropriate solvent to form a uniform resin solution or suspension; select one of the methods of coating, lamination or impregnation to fuse the resin solution or suspension and the base material, and then dry or cure the coated or laminated fresh-keeping pad according to the type of resin and process requirements to ensure that the resin is completely cured and fixed on the base material; use a cutting machine, a pressing machine and other equipment to cut the pearl cotton into the required shape and size, and perform necessary molding treatment, such as embossing, embossing, etc., to enhance its aesthetics and practicality; the treated pearl cotton layer is laminated and compounded with the pearl cotton. This step is usually achieved through heat pressing, bonding, etc. to ensure that the layers are tightly bonded to form an integrated fresh-keeping mat. Finally, the processed fresh-keeping mat is cut into the specified size, packaged and labeled for storage and transportation.

[0043] Compared with the existing fresh-keeping mats on the market, the fresh-keeping mat produced after the above production has the dual functions of cushioning and preservation, which not only preserves the freshness but also improves the safety of fresh food during transportation.
