包装材を提供するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a packaging material, and particularly to a package of a cold storage body that stores a cold storage body such as ice or dry ice and cools other products, It is intended to provide a packaging material suitable for packaging frozen or refrigerated goods.

維性包装資材に添着して使用することも知られている。Conventionally, when packaging products, cloth, paper or resin packaging materials have been used. In large-scale packaging, these packaging materials are suitable for packaging by a packaging machine, strength during transportation, and economy. In consideration of the above, desired processing is performed according to the purpose of use. Therefore, when packaging a regenerator such as ice, a multilayer packaging material using a polyamide (6-nylon) film for the outer layer and a linear polyethylene film for the inner layer is most commonly used. . It is also known to use a high-molecular water-absorbing polymer attached to a fibrous packaging material in order to absorb water during packaging.

る。[Problems to be Solved by the Invention] However, if the packaging material in which the polyamide (6 nylon) film and the ethylene film are laminated is used for the packaging of a cold storage body such as ice, the packaging of frozen desserts, and the frozen foods, the cooling box When transported and sold at normal temperature, moisture in the air will condense on the surface and adhere as water droplets, which impairs the value of the product or wets other products that come into contact with the cold storage in the same container However, it is not a preferable packaging material. Even if a laminated cloth in which a nonwoven fabric or the like is laminated on the film surface is used to absorb the condensed water droplets, the water absorbing ability is insufficient and the practical effect is small. Furthermore, even when a polymer such as a nonwoven fabric is coated with a polymer water-absorbing polymer and used, the polymer water-absorbing polymer shows fluidity when it absorbs water, so it easily falls off from the substrate or leaks out from the end of the laminate. Although it can be used for a hygroscopic sheet or a disposable diaper, it is not suitable for packaging a cold storage body or a frozen product.

材端部より外部へ漏れることも防止できる。Since the packaging material of the present invention has the above-described configuration, at the time of use, water droplets condensed on the surface of the nonwoven fabric are absorbed by the water-absorbing layer containing the high-molecular-weight water-absorbing polymer through the nonwoven fabric. The water-absorbing layer contains 50% or more of the high-molecular water-absorbing polymer, so that the water-absorbing ability does not decrease. However, if it is a small amount of 50% or less, the water-absorbing ability is reduced and is not practical. As a result of water absorption, the high-molecular water-absorbing polymer has fluidity, but a resin layer with a barrier property in its inner layer,
For example, since a polyamide film and a polyethylene resin layer are provided, there is no leakage toward the inside. Further, by providing the water-absorbing layer at a portion other than the sealing portion of the packaging material, it is possible to prevent the high-molecular water-absorbing polymer in the water-absorbing layer from leaking outside from the end of the packaging material.

材とした。Examples of the present invention will be described with reference to the accompanying drawings. In the figure, reference numeral 1 denotes a nonwoven fabric, which is made of a material having good water absorbency, for example, obtained by spinning a nylon 6-polymer and pressing with a calender roll. On the lower side of the nonwoven fabric 1, a coating layer 2 is printed, and the coating layer 2 is composed of, for example, a starch-acrylic acid graft polymer as a main component and a high-molecular water-absorbing polymer.
60 parts are suspended and dispersed in 37 parts of polyester and polyurethane resin and 3 parts of pigment and diluted with a mixed solvent of toluene, methyl ethyl ketone and isopropyl alcohol to a desired viscosity. Prepare a 90μ deep pattern plate in the part except for the heat seal part A, and use nylon spunbond (Asahi Kasei spunbond 41).

At this time, the coating amount of the coating was 11 g / m 2 , the amount of the high-molecular-weight water-absorbing polymer was 6.6 g / m 2 , and the non-woven fabric used was 41 g / m 2 . The polyamide film 3 and the polyethylene layer 4 are respectively adhered to the lower side of the coating layer 2. The mounting is performed by extruding a polyethylene adhesive to a thickness of 20 μ on the lower surface of the coating 2 to form the adhesive layer 5, and the lower side thereof is formed. An emblem (trade name, manufactured by Unitika) was laminated as a polyamide film 3 to a thickness of 15 μm. Further, an adhesive layer 5 was provided thereunder in a similar manner, and Tamapoly UB-1 (trade name: Tamapoli) was laminated and laminated with a thickness of 40 μm as a polyethylene layer 4 to obtain a packaging material.
