Description

Technical Field

[0001] This utility model relates to the field of absorbent pad technology, specifically an antibacterial multi-layer absorbent pad for fresh produce. Background Technology

[0002] Absorbent pads are an indispensable part of food packaging, especially for meat, seafood, and fruits and vegetables. Their primary function is to absorb and lock in excess moisture released during transportation and storage, helping to maintain freshness, reduce bacterial growth, and improve the market presentation of food. Currently, absorbent pads are commonly found on the market made from various materials, including plastic film pads, lint-free paper pads, and ordinary meltblown material pads. Plastic film pads, while isolating blood, do not absorb water, and the seeping blood can easily contaminate other areas. Lint-free paper pads have good absorbency but low strength, making them prone to tearing after absorbing blood. Ordinary hydrophilic meltblown pads suffer from low strength, are prone to pilling, and are susceptible to bacterial growth with prolonged contact with food. High-performance absorbent pads are typically composed of polyethylene and polypropylene blends, non-woven fabrics, superabsorbent polymers (SAP), and wood pulp paper. While they possess good absorbency and a certain level of physical strength, these materials themselves do not have antibacterial properties. Antimicrobial properties are extremely important in food packaging, especially for meat and seafood products.

[0003] Existing absorbent mats for fresh produce have the following shortcomings:

[0004] Non-woven fabrics, superabsorbent polymers (SAP), and wood pulp paper have limited water absorption properties, resulting in poor water absorption performance for absorbent pads. Furthermore, non-woven fabrics and wood pulp paper have poor elasticity and are easily deformed. When non-woven fabrics and wood pulp paper are deformed, their water absorption performance further decreases. Utility Model Content

[0005] In view of the problems existing in the current antibacterial multi-layer absorbent pad for fresh food, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide an antibacterial multilayer absorbent pad for fresh produce, which solves the problems of the limited absorbency of non-woven fabric, superabsorbent polymer (SAP) and wood pulp paper in existing absorbent pads for fresh produce, resulting in poor absorbency; and the poor elasticity of non-woven fabric and wood pulp paper, which makes them prone to deformation, further reducing their absorbency after deformation.

[0007] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0008] An antibacterial multi-layer absorbent pad for fresh produce includes an upper non-woven fabric layer, an absorbent layer below the upper non-woven fabric layer, a lower non-woven fabric layer below the absorbent layer, the absorbent layer being configured as a sponge layer, and a metal mesh ring layer being configured on the outer side of the sponge layer.

[0009] As a preferred embodiment of the antibacterial multilayer absorbent pad for fresh food described in this utility model, the metal mesh ring layer is composed of multiple elliptical rings and is made of steel wire.

[0010] In a preferred embodiment of the antibacterial multilayer absorbent mat for fresh food described in this utility model, the upper non-woven fabric layer and the sponge layer are bonded together with adhesive, and the lower non-woven fabric layer and the sponge layer are bonded together with adhesive.

[0011] As a preferred embodiment of the antibacterial multilayer absorbent pad for fresh food described in this utility model, wherein: a transverse metal mesh is provided in the inner cavity of the metal mesh ring layer, and the two ends of the transverse metal mesh are welded to the inner wall of the metal mesh ring layer.

[0012] As a preferred embodiment of the antibacterial multilayer absorbent pad for fresh food described in this utility model, the sponge layer is filled with bactericidal silver ions.

[0013] As a preferred embodiment of the antibacterial multilayer absorbent pad for fresh produce described in this utility model, it further includes a water-resistant membrane layer, wherein the water-resistant membrane layer is a plastic film made of polyethylene or polyvinyl chloride.

[0014] As a preferred embodiment of the antibacterial multilayer absorbent pad for fresh food described in this utility model, it further includes a longitudinal metal mesh disposed in the inner cavity of the metal mesh ring layer, wherein the two ends of the longitudinal metal mesh are welded to the inner wall of the metal mesh ring layer.

[0015] Compared with existing technologies:

[0016] 1. By setting a sponge layer between the upper and lower non-woven fabric layers, the sponge's water absorption and retention effect is better than that of non-woven fabric, thus greatly improving the water absorption and retention performance of the fresh food absorbent pad.

[0017] 2. By setting a metal mesh ring layer on the outside of the sponge layer, the steel wire metal mesh ring layer has better elasticity and is easier to recover its deformation. As the metal mesh ring layer recovers its deformation, it also drives the sponge layer to recover its deformation, thus avoiding the sponge from flattening and causing a significant decrease in water absorption and water retention effect, making the fresh food absorbent pad have a longer service life.

[0018] 3. By setting transverse and longitudinal metal meshes inside the metal mesh ring layer, and by bonding the transverse and longitudinal metal meshes to the sponge layer, the sponge layer can more easily recover its deformation. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Example 1:

[0028] This utility model provides an antibacterial multi-layer absorbent pad for fresh produce. Please refer to [link / reference]. Figure 1-3 The product includes an upper nonwoven fabric layer 1, an absorbent layer below the upper nonwoven fabric layer 1, and a lower nonwoven fabric layer 3 below the absorbent layer. The absorbent layer is a sponge layer 4, which has better absorbency than the nonwoven fabric. Therefore, the presence of the sponge layer 4 significantly improves the absorbency of the fresh produce absorbent pad. Furthermore, the sponge layer 4 has better water-locking effect than the nonwoven fabric, thus also improving the water-locking effect of the fresh produce absorbent pad. The sponge layer 4 is filled with antibacterial silver ions. The upper nonwoven fabric layer 1 and the sponge layer 4 are bonded together with adhesive, as are the lower nonwoven fabric layer 3 and the sponge layer 4. A metal mesh ring layer 2 is provided on the outside of the sponge layer 4. The metal mesh ring layer 2 is composed of multiple elliptical rings, which makes the metal mesh ring layer 2 more elastic and easier to recover its deformation. The metal mesh ring layer 2 is made of steel wire.

[0029] The outer side of the sponge layer 4 is bonded to the metal mesh ring layer 2, so that when the fresh absorbent pad is formed, the metal mesh ring layer 2 recovers its shape and drives the sponge layer 4 to recover its shape, thereby ensuring the water absorption and water retention effect of the sponge layer 4.

[0030] A transverse metal mesh 21 is provided in the inner cavity of the metal mesh ring layer 2. The two ends of the transverse metal mesh 21 are welded to the inner wall of the metal mesh ring layer 2. The transverse metal mesh 21 is also bonded to the sponge layer 4.

[0031] Example 2:

[0032] See attached document Figure 4-5 Unlike Example 1, it also includes a water-blocking film layer 5, which is a plastic film made of polyethylene or polyvinyl chloride. In this case, the plastic film can block water on one side of the fresh food absorbent pad, so that when you hold the non-woven fabric layer 1, the absorbed water will not soak into your hands.

[0033] Example 3:

[0034] See attached document Figure 6 Unlike Embodiment 1, it also includes a longitudinal metal mesh 22 disposed in the inner cavity of the metal mesh ring layer 2, with both ends of the longitudinal metal mesh 22 welded to the inner wall of the metal mesh ring layer 2; supported by the longitudinal metal mesh 22, the fresh food absorbent pad has better elasticity and is more likely to recover its deformation.

[0035] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
