New Description: [New Technology Field] This creation is an absorbent material used for packaging absorbent materials, especially for air, sea and long-distance transportation. [Prior Art] Absorbent materials used for packaging, especially for the packaging of articles during air, sea and long-distance transportation, especially for packaging fresh fruits and vegetables, meat products or other liquid-containing articles with Water leakage and extravasation can damage articles, even the destruction of transportation vehicles, and the positive purpose is to effectively keep the items fresh, and to protect the environment from pollution and to avoid damage caused by liquid infiltration. A proper packaging of articles to avoid leakage and extravasation is an important issue. In the traditional absorbent material design, one or more layers of absorbent paper are used as the inner layer, and the kraft paper tape is used as the surface layer seal. However, the absorbent paper absorbs water, and under heavy pressure, the moisture will be squeezed out again to infiltrate and contaminate the articles and the environment. Or the plastic film is the outer layer, but only a little to prevent extravasation, and can not prevent extravasation. φ With the development of technology, the polymer absorbent (SAP) is used instead of the absorbent paper, and the liquid is not squeezed out again after the liquid absorption system absorbs the liquid. However, the molecular size of the polymer absorber is easy to leak out, that is, the polymer absorber is completely sealed to avoid extravasation when packaging the article. The conventional technique uses a resin lining as a surface layer, and because of its low density, it cannot prevent the polymer from absorbing infiltration, and the point breakage hole is directly in the region between the absorbing materials, causing the absorbing molecules to leak from the point break. Therefore, how to provide a function of completely sealing the polymer absorber to the inner layer is an absorbent material. M287298 buffer surrounds an absorption zone, and the periphery of the buffer is sealed. The structure is as follows: Please refer to the first figure, which is a schematic view of a single absorbent structure according to an embodiment of the present invention. The absorption zone 20, a buffer zone 30 is planned on the periphery of the absorption zone, and a buffer zone is planned to surround the buffer zone 30, and a close-fitting edge 40 is formed in the adhesion zone. The absorbing zone 20 functions to absorb liquid, and is a main structure of the absorbing material. The first surface layer, the absorbing layer and the second surface layer are stacked, and the buffer zone 30 provides a buffer space composed of a first surface layer and a second surface layer. The absorption layer of the absorption zone 20 is in an expansion space after absorbing the liquid, and the adhesion zone 40 is formed by stacking the first surface layer and the second surface layer, and is pressed and sealed by ultrasonic waves, high frequency and hot pressing method. Absorbent material. The second figure is a schematic view showing the front view of a continuous absorbent material. In one embodiment, a point break 50 is provided in the close side 40 of the two adjacent absorbent members to facilitate tearing of the adjacent absorbent members into separate absorbent members, and the point breaks 50 are disposed on the close sides. In the case of 40, the adhesive absorbing material is not damaged. Therefore, in the absorbing material of each unit, the close-fitting side 40 is surrounded by the periphery, and the polymer water absorbing body is prevented from leaking from the side. According to the above, the spatial planning of the absorbent material is sealed by the absorption zone 20, the buffer zone 30 and the adhesive edge 40, and the stack of the absorbent material is composed of the first skin layer, the absorbent layer and the second skin layer. Structure of the material: Referring to the third figure, this figure illustrates the first embodiment of the structure of the absorbent material. The absorbent structure 10 of this embodiment is distributed in the absorption zone of the absorbent material, and is formed by stacking the first skin layer 14, the adhesive layer 13, the polymer absorbent body layer 12 and the second skin layer 11. The buffer zone and the adhesion zone are composed of a first surface layer and a second surface layer, and the adhesion zone is closely formed to form a tight edge. The function and constituent materials of each layer are described below: The first surface layer 14 is used for packaging the outer layer of the article. The utility model has the functions of being gas-tight and preventing internal and external osmosis. In this embodiment, the polyethylene layer of the cladding material is the first surface layer, which has the function of being gas-tight and preventing the passage of liquid; the absorption layer 12 is a polymer absorber layer, and its work; M287298 It can be used for absorbing liquid, mainly composed of polymer absorber. In order to adhere to the absorption zone, it must be mixed with hot melt glue to form a polymer absorber layer; the second surface layer u cladding material is polypropylene layer. The inner layer of the article has a liquid molecule that is absorbed by the absorbing molecular layer of the absorbing layer of the absorbing layer, but the polymer absorbing body cannot pass through the polypropylene to prevent back oozing; the adhesive layer 13 is used to strengthen the first surface layer and the second surface layer. In this case, the polypropylene layer is a polypropylene layer, and the adhesive layer of the polyethylene layer of the first skin layer 14 and the polypropylene layer of the first skin layer 11 has a homogenous structure to enhance the adhesion. The fourth figure is the second embodiment of the structure of the absorbent material. The absorbent material structure 15 is distributed in the suction receiving area. The first surface layer 16, the absorbent layer 17 and the second surface layer 18 are stacked, and one of the surface covering materials is It is a polypropylene layer that allows liquid molecules to pass through, but the polymer absorber cannot pass, achieving the effect of no osmosis. The buffer layer and the adhesion zone only contain the surface layer, and the absorption layer is a polymer absorption layer. Both of these skin layers allow water to pass through. They are absorbed by the absorbent layer and cannot be rewet after absorption. In the same way, the cladding materials of the two surface layers can be replaced with absorbent paper, and the same effect can be achieved. It should be noted that the choice of single layer or multiple layers and materials in the design of the surface layer is to allow the liquid molecules to be absorbed through the surface layer of the adjacent articles and cannot be rewet back when packaging the articles, as in the case of the first example, the polyethylene layer is used for packaging. When the item is in the outer layer, it is more airtight. Others have different surface design due to design considerations, but white can use the absorption area 20, the buffer zone 30 and the close side 40 to achieve the polymer absorber. The effect of seepage and rewet. The application of absorbent materials is mostly used for packaging articles, especially in the packaging of liquid-containing articles, especially for air transport, sea transport and other long-distance transport. [Using absorption zone 20, buffer zone 30 and close-fitting edge 40 It achieves the function of absorbing liquids' and reduces the backflow of absorbent materials and environmental pollution due to sealing. For example, when implementing, an absorbent material is placed on the pallet, and the article is packaged after the article is placed. However, the article needs to be completely encapsulated inside the absorbent material, so that the absorbent material can achieve its function, that is, the internal article is protected from the outside. Contamination of liquid or moisture or to avoid the diffusion of internal liquids to contaminate the external environment of 8 M287298. In summary, the present invention proposes an absorbent material which has the following advantages: 1. The buffer zone is added to allow the polymer absorbent body to have an expansion space after water absorption, so that the polymer absorbent body is not extruded outside the absorbent material. leak. 2. Stitch the periphery of the absorbent material and seal the polymer absorbent to the inner layer. 3. Set a broken line in the tight side of the absorbent material to make the absorbent material easy to tear without damaging the structure of the absorbent material. 4. Improve the material of the inner layer, such as using a polymer absorber to absorb liquid. 5. Different materials or structures can be used on the surface to achieve different effects, such as the use of polyethylene to achieve airtight effect. It is only the above-described preferred embodiments of the present invention, and the scope of the present invention cannot be limited. That is to say, the equivalent changes and modifications made by the applicants in accordance with the scope of this patent application will remain without losing the spirit and scope of this creation, and therefore should be regarded as the further implementation of this creation.
