Description of the Invention (>) [Problems to be Solved by the Invention] When manufacturing the above-mentioned conventional multilayer structure packaging papers 31 and 41, the substrate sheet 32 constituting layer A, the laminated layer (Fig. 4 (a)), or the substrate The process of laminating the material sheet 42, the laminating layer 43, and the reinforcing material 46 (FIG. 4 (b)), and the process of locally adhering the A layer and the B layer are necessary, which are quite troublesome. In the conventional multi-layered packaging papers 31 and 41 described above, since the A and B layers are laminated through the delicate separation of the adhesive layers 35 and 45, spaces 37 and 47 are easily formed between the two layers. Therefore, it is difficult to wind the multi-layered wrapping paper 31 and 41 densely, and it is not easy to make tight packing. The present invention has been accomplished in view of these inconveniences, and its object is to provide a multi-layered packaging paper that can be manufactured by a single lamination process, and its winding and packaging are easy. [Means for Solving the Problems] The multilayer structure packaging paper of the present invention for solving the above-mentioned problems includes a substrate sheet, a synthetic resin laminated layer laminated on the substrate sheet, and a film; the aforementioned laminated layer The thin film is tightly laminated to form a local bonding state (request 1). The term "tight lamination" in this specification means that the lamination layer and the film are laminated with very little clearance without applying any load to the multilayer structure packaging paper from the outside, and it does not mean that the two layers are interposed. Lamination is done in a space-free manner. Therefore, when an external force acts on the multi-layered packaging paper due to bending or bending, a gap may sometimes be formed between the laminated layer and the film, particularly at the non-adhered portion. --R ---, ----- yi-- (Please read the precautions on the back before filling out this page), π Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 1¾: Standards apply to Chinese National Standards (CNS) Α4 Specifications (210X29 ^ mm) 531489 A7 B7 V. Description of the invention (j) (Please read the precautions on the back before filling this page) According to this method, the laminated layer and the thin film system form a local bonding state, and the previous conventional Multi-layered packaging paper is the same, which can prevent the layers and films composed of the base sheet and the laminated layer from cracking at the same time, and prevent difficult packaging operations due to excessive rigidity. In addition, the multilayer structure packaging paper of the present invention, because the laminated layer and the film are tightly laminated with a small gap, can not cause a loose feeling at all, and can make the winding operation of the multilayer structure packaging paper and the use of the packaging paper. The packaging operation becomes easy. As a means for obtaining the local bonding state, a sheet of an opening material may be inserted between the laminated layer and the film (request 2). Here, the "sheet with an opening material" refers to a sheet having an opening in a sheet surface. According to this method, the laminated layer and the film are not adhered in a part where the opening material sheet is interposed therebetween, and the laminated layer and the film are adhered in the opening part, thereby forming a local bonding state. In addition, by adjusting the size of the opening, the area ratio of the bonding portion, that is, the bonding strength can be controlled. The above-mentioned sheet of opening material printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs may be made of flat silk, cut cloth, non-woven cloth or group cloth (request item 3). The "cut cloth" as used herein refers to a cloth made of split fiber and has a plurality of openings. The so-called "fabric" is a tape made of yarns, high-density polyethylene, polypropylene, etc., which are continuously and vertically laminated to form a grid. Then, a hot-melt adhesive is used. Wait for the fixed warp and weft orthogonal non-woven fabric. According to this method, the thickness of the opening material sheet can be reduced, and at the same time, the opening portion can be easily formed. By thinning the sheet of the opening material in such a manner, a structure in which the synthetic resin constituting the lamination layer through the opening portion easily contacts the film will be formed. This paper size applies to China National Standard (CNS) A4 (21〇 ×; 29 ^ mm) 531489 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7 V. Description of the Invention (I). FIG. 1 is a schematic cross-sectional view showing a multilayer structure packaging paper according to a first embodiment of the present invention, FIG. 2 is a schematic cross-sectional view showing a multilayer structure packaging paper according to a second embodiment of the present invention, and FIG. 3 is a schematic cross-sectional view of a multilayer structure packaging paper according to an embodiment. The structure of the multi-layered structure wrapping paper 1 in FIG. 1 is that a base sheet 2, a laminated layer 3, and a film 4 are sequentially laminated, and an opening sheet 5 having an opening 6 is inserted between the laminated layer 3 and the film 4 ( (Equivalent to the sheet of opening material). Therefore, only the portion of the opening portion 6 of the opening sheet 5 abuts between the laminated layer 3 and the film 4, and is then adhered. On the other hand, there is a portion where the opening sheet 5 is present between the laminated layer 3 and the film 4 because the opening sheet 5 prevents the two from adhering. Therefore, the 'laminated layer 3 and the thin film 4 form a local bonding property. The above-mentioned multi-layered packaging paper 1 is partially bonded due to the A layer composed of the base sheet 2 and the laminated layer 3 and the B layer composed of the film 4. During packaging, even if the pear shear force acts on the A layer The direction of peeling between layer B and layer B will prevent the two layers from cracking at the same time, compared with the two layers of packaging paper which are completely attached. In addition, the rain layer is in a partially bonded state. Since it has a non-adhered portion, the wrapping paper itself is not excessively hard, and packaging work and winding work of the wrapping paper can be facilitated. In addition, since it is not easy to form a space between the A and B layers, and it does not give a loose feeling, it can be densely and easily wound, and packaging operations are also easy. Considering the related effects, the bonding area ratio of the laminated layer 3 and the film 4 should preferably be 1% or more and 30% or less. Examples of the opening sheet 5 having the opening section 6 include a hook. Flat wires such as polyethylene or polypropylene are formed so as to form the opening section 6 (please read the precautions on the back before filling this page)

Although the thickness of the laminated layer 3 is not particularly limited, it is generally about 8 / zm or more and 100 / zm or less. Synthetic resin can be used for the film 4. Examples of usable synthetic resins include polyethylene, polypropylene, polymethylpentene, ethylene vinyl acetate resin, ethylene ethyl methacrylate resin, ethylene acrylic resin, and ethylene methacrylic acid. Resins, ethylene methyl acrylate resins, ionomers, polyamide resins, polyvinyl alcohol, polyesters, etc. Polyethylene, polypropylene, and the like polymerized using a so-called aromatic cycloolefin metal derivative catalyst are also applicable. Here, the manufacturing method of this multilayer structure packaging paper 1 is demonstrated. First, while the substrate sheet 2, the opening sheet 5 and the film 4 are sequentially laminated from the feed roller and then sent to the crimping roller, the molten synthetic resin composition constituting the laminated layer 3 The T-die is extruded in a film shape between the base sheet 2 and the open sheet 5, and then laminated and pressed. According to the above manufacturing method, the laminated layer 3 can be formed between the base sheet 2 and the film 4, and the laminated layer 3 and the film 4 can be made to pass through only the opening portion 6 of the opening sheet 5. The multilayer structure packaging paper 11 shown in FIG. 2 is a structure in which a substrate sheet 12, a lamination layer 13 and a film 14 are sequentially laminated. The inner surface of the film 14 will be partially coated with an accelerating (inhibiting) agent 15 to The layer A composed of the base sheet 12 and the laminated layer 13 and the layer B composed of the thin film 14 are brought into a partial bonding state.

Description of the invention (f) ~, laminated layer 13 and film 14, The substrate sheet 2, the laminated layer 3, and the film 4 of the multilayer structure packaging paper 1 of FIG. 1 are the same. The coating on the inside of the film 14 is performed before lamination. As a coating material for this coating, when the synthetic resin used for the laminated layer 13 and the film 14 is a combination with poor adhesion (for example, when a polyester film and a PE laminated layer are used), coating the inner surface of the film 14 can promote the adhesion. (For example, organic titanium-based, isocyanate-based, polyethyleneimine-based, polybutadiene-based, polyurethane-based, or polyester-based tackifier coatings). In contrast, when the synthetic resin used for the laminated layer 13 and the film I4 is a combination with good adhesion (for example, a polyethylene film and a polyethylene laminated layer, or a PP film and a pp laminated layer), the film I4 is used. The coating on the inside can suppress the adhesion inhibitor (for example, silicone, fluorine-based coating agent, cellulose-based coating agent, etc.). The manufacturing method of the multilayer structure packaging paper of FIG. 2 having the above structure is substantially the same as the manufacturing method of the multilayer structure packaging paper of FIG. 1 described above, and the substrate sheet I2 and the film I4 are sequentially sent to the crimping roller. The molten synthetic resin composition constituting the laminated layer I3 is thinly extruded between the two layers by a self-shaped die, and then pressurized. The multilayer structure packaging is also as described above, because the base sheet U and the laminated layer 13 are composed of ^ '11' and the layer B composed of the film μ forms a local bond. If the layer A is enough to prevent overturning, it is not necessary to stop it. The structure of the multi-layered packaging paper 21 shown in FIG. 3 is that after laminating ^, the laminated layer 23 and the film 24 in order, a plurality of strip-shaped sheets 25 are arranged side by side between the Fu sheets 22 and 24 of the layer a. Configuration and: Insert with two and thin film method.

Description of the invention (f) 25, except for the above figure 1 The multi-layered wrapping paper 21 also has the multi-layered wrapping paper 21, as described above, because the A-layer composed of the base sheet 22 and the laminated layer 23 and the B-layer composed of the film 24 form a local bonding state, so it can be used and The above-mentioned multilayer structure wrapping paper 1 of Fig. 1 and the multilayer structure wrapping paper 11 of Fig. 2 have the same function. As the material of the strip-shaped sheet 25, the same material as the substrate sheet 1 described above can be used as a paper material and a synthetic resin [Effects of the invention] As described above, the multilayer structure packaging paper according to the present invention can be manufactured by a single lamination process, so that the manufacturing cost can be reduced. The two-layered system is in a partially bonded state. , Can prevent two layers from cracking at the same time during packaging. In the following state, because there is a part that is not connected, the wrapping paper itself is not too hard, and it is easy to perform wrapping & wrapping or wrapping paper winding operations. Furthermore, the upper layer and the lower layer are tightly bonded without loosening. The sense of exaggeration can be dense and easy to wind up, and the packaging operation becomes easier.
