Further, it is also prevalent to form a so-called 丨-shaped slit or a 乂V-shaped slit 4 slit in the peripheral seal portion to improve the openness. On the other hand, for example, as an easy-opening device such as a lid of a fruit-and-white container, a method of using an easily peelable film as a sealing layer (a sealing material layer) is widely used as a flow lamp, but in recent years, some people have discussed such an easy The release film is also applied to a film package such as a pillow-shaped package, and the heat-sealed portion of the film package has an easy-opening property in a state of "face seal". In the film package, all the sealing portions including the unsealing portion become easy to be smashed: the mountain seal body is so close to the lid of the container, and the management of the sealing strength of the height is required. For example, the Sheng-Zhuang W-Bag body is more likely to be deformed by internal and external pressure than the rigid container. The sentence, w ^ transport, storage, etc. are prone to break the bag, so the sealing part: the required level of pressure is also higher. . & For example, the contents are wet wipes, etc. When it is unopened, it is necessary to prevent drying during long-term storage, and a high degree of thirst resistance is required.曰— ^ ”, and after the opening, the contents are still unable to be used up once and the necessary opening of the seal is not necessary after the opening of the seal. Therefore, in the film package In the face seal, 103365.doc 1278411 The more demanding requirements are inherently and moderately easy to open and it is necessary to control the performance of the peripheral part of the container compared to the cover material of the container. The mechanism of the layer that is easily peeled off has a method of utilizing cohesive peeling and interface peeling, but in the surface sealing of the film package, as described above, the sealing strength is mainly used because of the requirement for stable sealing strength. A cohesive-type sealing material which is considered to be superior. As such a cohesive-breaking type sealing material, for example, in the following Patent Document 1, a polyolefin resin or a compound is sequentially laminated on a film substrate. : a layer composed of a copolymer resin (th. (4), a polypropylene resin (resin..., a polystyrene resin (resin B), a graft polymer having a structure in which polystyrene is grafted to a polypropylene-based structure (resin c) Composition The composition of the layer (second layer) of the resin composition is referred to as the second layer, and it is revealed that (4) the resin composition as the second layer is a seal using a coating body of a polypropylene resin, and the use is shown to utilize cohesive failure. On the other hand, for example, in a package containing a content containing moisture such as a wet tissue for carrying, the package is small in size and easy to carry, but it is also required to easily take out the contents. For example, in the following Patent Document 2, a package in which a crack is formed in a bag body to form an opening portion and a cover member that can be peeled off by an adhesive agent is provided from above is sealed with a fiber material or the like.

In particular, in the case of a polypropylene-based easily peelable sealing material which is excellent in heat resistance and strong in film strength and can be filled at a high speed, when a cohesive peeling type is used, a sealing condition of a moderately easy-opening property can be obtained. If the sealing condition is too small, the sealing condition is too weak, resulting in insufficient sealing property, or the sealing condition is too strong, resulting in a problem that the opening condition is insufficient. On the other hand, in the case of the package 300 shown in Patent Document 2, the size of the opening portion of the shape can be limited, so that there is a problem that the contents are difficult to be taken out, and it is desirable to use the wet wipes for convenience. The package is made smaller; 'Because there is a limit to increase the opening area, the invention is developed in accordance with the question of η θ on the same day, and the purpose is to face the surface seal. Providing a seal that is superior to the sealant-type sealant material in that it has two excellent sealing stabilitys, and that can achieve both easy-opening and sealing properties. In addition, it provides a package that can be used to take out the open area of the content using the surface-faced dense body. body. The present invention is for providing an easy-to-open type of easy-opening package and a heat sealable seal comprising the following composition; A laminate film comprising a heat-resistant layer formed by heat-sealing a plurality of layers. The co-extruded layer of the above-mentioned co-extruded sealing layer comprises a layer (4) which comprises a polypropylene-based layer. Configuration ^ 103365.doc 1278411 The support layer of the assembly, including the resin group of Polypropylene and Polyethylene Women. . . . , 多层 多层 配置 配置 = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = The sealing layer of the first layer, so the peeling layer of the innermost layer is peeled off on one side: two sides. Therefore, in the film package = surface seal, the seal strength can be obtained as compared with the conventional one, and the easy-opening property and the sealing property can be achieved under wider sealing conditions (temperature, force, time). Further, the "resin layer" having heat resistance is the outermost one at the time of heat sealing, and the layer having heat resistance higher than the heat sealing temperature. For example, the stretching is oriented uniaxially or biaxially, such as stretched polyamine, stretched polypropylene, etc., to orient it = film. Further, the "sealing layer" of the heat sealable seal is the innermost layer which can be heat-sealed at a temperature lower than the heat seal temperature during heat sealing. The "support layer" of the co-extruded layer is left on the side of the substrate layer at the time of leaving the heat (fourth) portion, and the "peeling layer" of the sound is extruded, which is separated from the aforementioned support stripping when the heat sealing portion is peeled off. Floor. (2) The easy-opening package according to (1), wherein the polypropylene-based homopolymer of the support layer is a polypropylene-based random polymer of the release layer. According to this aspect, when a polypropylene having a high crystallinity is used as a homopolymer having a high crystallinity, it is possible to obtain a film which is inherently strong in polypropylene, which is suitable for high catching. Further, when the polypropylene having a low crystallinity is used as the polypropylene of the release layer, the compatibility between the support layer and the release layer can be appropriately adjusted, and the easy-opening property at the time of interlayer peeling, i.e., an appropriate interlayer adhesion strength, can be obtained. Further, when the polylayer of the release layer is used, the compatibility of the polyethylene can be increased, so that the layer of the peeling can be agglomerated and destroyed. It is more uniform and can prevent peeling. The so-called "hypopolymer of propylene" is a separate polymer of propylene. Further, a random polymer of polypropylene is a polymer which is obtained by randomly blending a copolymerized dimer such as a woman or a k-butanine into a W-woman chain. λ early =) In the easy-opening package contained in item (1) or (7), the strength of the front seal is 7 or more and 7N/15mnm. According to this aspect, when the sealing strength is set to 4 N/i5 or more, the sealing property can be sufficiently sealed, and the film package can be prevented from being transported and stored in the watch case. Further, for example, in the case where the contents are wet wipes or the like, drying of the contents can be prevented. Further, when the sealing strength is set to 7 N/i 5 Å or less, an appropriate ease of opening property can be imparted. Further, the above-mentioned sealing strength is, for example, a measurement value under the conditions of a sealing time of 〇5 seconds, a sealing 遂〇% MhW, and a tensile speed of the test piece of 3 (10) _/min, and the sealing strength of the above-mentioned range is at a sealing temperature of 14 () to 16(). The wide range of 〇 is obtained. Further, 'the sealing machine is not particularly limited. For example, the two-purpose tip Doshila Tnc (trade name; the hot-sealing machine known to the company) (4)-type package, which belongs to the pillow-shaped package The easy-opening package according to any one of (1) to (7). The missing of the pillow-shaped package is that it is difficult to open without a key portion such as a slit. In this invention, a slit is not required. (10) In the easy-opening package according to the item (4), the upper and lower transverse seal portions and the longitudinal seal portion are formed in the pillow-shaped package by the heat welding seal, and the above-mentioned layer is formed. The film is provided with a slit line 'to form an opening region for taking out the content from the pillow-shaped package body to cover the opening region, and a cover material which can be peeled off from the laminated film is adhered to the surface of the laminated film, and the cover is peeled off a material, which is torn from the aforementioned open area to form the opening

According to this aspect, when the cover material is peeled off, the opening area is separated by the slit line of the adhesive π on the back surface of the cover material, and is pulled up to be integrally separated from the cover material. Therefore, when the area surrounded by the crucible is opened, the content is formed, and the tearing-off guiding mechanism continues to tear open from the opening area, and the opening portion which is formed by the opening D region to the horizontal sealing portion has an easy-opening property.

It is also possible to form the tearing line in a so-called "half-degree 2 I-month cut" state by the thickness of the laminated film. (6) In the easy-opening package according to the item (5), the tearing guide mechanism is formed by the stretching direction of the stretched film constituting the laminated film as the tearing direction. According to this aspect, as long as the stretched film is used as a part of the laminated film, the step of additionally forming the tear-away guiding mechanism is not required. Further, the stretched film is preferably a uniaxially or biaxially stretched film having a high degree of retractability, and more preferably a uniaxially stretched film which is excellent in tearability (straight cut property). Such a film is conventionally known, and a commercially available product can be suitably used. (7) The easy-opening package according to any one of (1) to (6), wherein the content contained in the package is a wet tissue for carrying. According to this aspect, the wet tissue for carrying is usually housed in the pillow-shaped package. It is necessary to simply take out the wet tissue therefrom, and since it is a small package, a particularly large opening is required. In this regard, in the easy-open package of the present invention, the packaging material of the above (5) or (6) is particularly used, and a large opening portion can be formed, and the wet tissue can be easily taken out. Moreover, since the sealing property is also sufficient, it is possible to provide a package which can prevent the contents from being dried and can be protected from long-term rotation. (8) In the easy-opening package as set forth in (7), the transverse seal portion is sealed to a surface having a width of 2 mm or more. According to this wicking, the width of the upper and lower seal portions of the octagonal shape of the small pillow-shaped package such as the above-mentioned wet tissue for carrying is narrow. Therefore, in order to obtain the true = sealability, it is sometimes necessary to apply the seal of the palace to seal the surface seal of 2_ or more instead of applying the line seal to the tenth. Usually, the seal strength is very high, but the invention is easy to open the package. In this case, even if the surface is sealed in two or more faces, the easy-sealing property of the sealing portion can be obtained, so that the mouth portion of the large portion can be easily formed. EFFECTS OF THE INVENTION According to the present invention, in a film package-destructive sealing material which is more excellent in sealing, it is possible to provide a package which is more condensed and sealable. The wide sealing stability and the opening for taking out the contents of the easy-to-install body can be provided: a package body capable of increasing the package or the like can be provided.

As shown in Fig. 1, the package 100 is a pillow-shaped package made of a laminated film 110 of a flexible packaging material. In the figure, the 13b 132 is a horizontally sealed portion, and a vertical (back seal) sealing portion (not shown) is provided at the center portion on the back side of Fig. 1 . On the upper surface side of the laminated film 11 of the package 100, as shown in Fig. 1, a slit line 111 is formed in a shape of a figure. With this slit-shaped slit line, an opening region 150 is provided inside the word. This open area 15 turns thereafter to become a portion cut by the peeling of the cover material 120. However, in order to cover the open area 15 103 103365.doc -13 - 1278411, the adhesive has a cover material 12 舌 of the tongue portion °. Below the cover material 120. Parts other than P 121 < and 5 have an adhesive layer (not shown). However, the adhesive film layer can be used to smudge the laminated film 11 〇 and the cover material 12 (). Here, the term "adhesive" can be peeled off and re-closed. The extension of the two terminals of the word "the slit line 111 on the laminated film 110" is used for inspection. The sealing portion 132 continues the two parallel tearing guides. In the yoke type sorrow, the tearing guide mechanism 160 is described as an imaginary line, and actually, the stretching of the Tiantiantian is called the film 11 The direction in which the film is stretched and the direction of the imaginary line, and the direction of the stretched film becomes the tearing guide mechanism 160. <Composition of laminated film> As the laminated film 11 of the package 100 〇, a laminated film of a base material layer and a sealing layer is used. Fig. 2 shows an example of a structure of a laminated film 11 。. This laminated film is laminated by an outer layer by a dry lamination method through an adhesive. The material layer a/intermediate layer B/sealing layer C. The seal layer C constitutes a coextruded film including the support layer ci disposed further on the intermediate layer B side and the release layer C2 disposed on the innermost surface. As shown, in the transverse sealing portion 132 of the package 100, two laminated films 110 are thermally welded by heat sealing, that is, the peeling of the innermost layer facing each other. The bonding layer C2 is integrated with each other by the solder sealing, and the bonding surface is integrated. The structure of the laminated crucible 110 can be a conventionally known configuration, and is not particularly limited. For example, the outer layer side may be sequentially used as the substrate layer. / Two layers of the sealing layer, three layers of the base layer / intermediate layer / sealing layer, four layers of the base layer / the first intermediate layer / the second intermediate layer / the sealing layer, etc. The lamination method can be used The dry lamination method of the subsequent lamination may also be laminated using an extrusion bonding method using polyethylene or polypropylene 103365.doc 14 1278411. <Substrate Layer A Intermediate Layer B > As the substrate layer A, A conventional stretched film such as a stretched polyester, a stretched polyamide or a stretched polypropylene can be exemplified. Further, as the intermediate layer B, a paper, a nonwoven fabric, an aluminum foil or the like can be suitably combined in addition to the stretched film described above. Barrier layer, etc. The stretching of the stretched film may be uniaxial stretching or biaxial stretching. <Sealing layer C > In the present invention, the sealing layer c is coextruded by peeling between layers The layer is formed by the layer, and the coextruded layer is characterized in that it is disposed on the side of the substrate layer A and is mainly made of polypropylene. The support layer C1 of the body is a multilayer of the release layer 02 disposed on the innermost layer of the laminated film mainly composed of a resin composition containing polypropylene and polyethylene. The entire sealing layer C is a coextruded layer which can be peeled off between the layers. The thickness of the dense layer C is 25 μm to 40 μπ. The support layer Cl is mainly composed of polypropylene, preferably a homopolymer polypropylene and the thickness of the support layer C1 is 8 整个 of the entire sealing layer c. % to 9〇% is preferable, and it is preferable to use 20 μm to 35 μm on the J body. The release layer C2 is a polypropylene composition comprising polypropylene and a polyethylene resin, preferably a random polymerization. Further, the peeling layer is preferably 10% to 2% by weight of the entire sealing layer, and specifically, 5_10 μm is ideal. The coextruded layer having the above composition may be formed by coextrusion bonding or by using an adhesive or a polysulphate laminated coextruded film. As a co-extruded film, a commercially available film can also be used. As a film of such a delamination, the film is exemplified by Aroma ΤΡ6 (trade name: manufactured by Showa Denko Plastics Co., Ltd.). Further, the sealing layer C is not limited to the two layers as shown in Fig. 2, and three or more layers may be used. <Cutting line and opening area> The notch line 111 is not particularly limited as long as it is provided so that the opening area 15 5 can be formed. Further, the size of the opening area 150 as the outlet can be appropriately selected in accordance with the size of the package 1 and the size and shape of the contents to be taken out. For example, in the case where the contents are wet wipes for carrying, the size of the opening area 150 is preferably 5><20111111 to 40>< 60111111.丄i 夕 贝 贝 贝 贝 贝 贝 贝 贝 贝 贝 贝 贝 贝 贝 贝 贝 贝 贝 贝 贝 贝 贝 贝 贝 贝 贝 贝 贝 贝 贝 贝 贝 贝 贝 贝 贝 贝 贝<Tear-Off Guide Mechanism> As described above, in the present embodiment, the tear-opening guide mechanism 16 is described as: a desired line, actually the stretching direction of the stretched film constituting the laminated film 110 and The direction of the imaginary line is uniform, and the orientation of the stretched film becomes the tear-away guide mechanism (10). Specifically, for example, as long as the base material layer a of FIG. 2 is used as the stretched film, it is preferred to use a uniaxial or biaxially stretched film having high orientation, and it is more preferable to use so-called easy tearability ( Uniaxially stretched film of straight cut. As the stretched film, a commercially available product conventionally known can be used. The tear-opening guiding mechanism 160 is not limited to the above-described stretching orientation, and for example, a tearing line may be formed on the laminated film 1 . In this case, the tear line may be formed to penetrate the package, or a so-called half-cut state may be formed, but it is preferable to adopt a half-cut state in order to maintain the sealing property of the entire package. Also, the half cut " ~ person, the cow cuts, for example, Kelly 103365.doc -16-1278411 is formed by irradiation of laser light or mechanical extraction of the base layer A. <cover material> A conventional method such as knife processing is for example only

As the adhesive layer, a conventional hot melt layer or the like can be used. <Action> ^ Next, the action of the package 1 说明 will be described using Figs. 4 to 7 . 4 is a perspective view showing a state in which the cover material 12 is peeled off in FIG. 1, and FIG. 5 is a perspective view showing a state in which the peeling guide mechanism is torn along the tearing guide mechanism to the horizontal seal portion 132, and FIG. 6 is along the line. Fig. 5 is a cross-sectional view of the line and an enlarged view of the vicinity of the horizontal seal portion, and Fig. 7 is a perspective view showing a state in which the tearing portion is removed. First, as shown in Fig. 4, in the package body 1A, the cover material 12 is peeled off in the direction of the arrow by the side of the tongue portion 121 of the cover member 12. Then, the adhesive layer on the back side of the cover material 120 is adhered to the opening region 15A, and is cut away from the opening region 150 of the film 110 along the slit line. Thereby, the opening portion 11 can be formed on the upper surface of the film 11 to exhibit a state in which the content can be recognized. Next, as shown in Fig. 5, when the cover material 12 is further peeled off, the laminated film 11 can be torn along the two parallel imaginary lines 1 60 formed by the two end portions of the slit line 111 of the cross-shape. The horizontal seal portion 132 is directly reached. At this time, in the horizontal seal portion 132, the seal layer C is an interlayer peeling type seal layer. Therefore, as shown in FIG. 6, when the horizontal seal portion 132 is reached, one portion of the peeling layer C2 is removed (FIG. 103365.doc -17-1278411 6 The peeling layer C2) on the upper side becomes the root portion 18〇, whereby the support layer is peeled off between the layers of the peeling surface 170. Therefore, the laminated sheet 11 which reaches the edge of the sealing portion 132 can be easily cut out. (), finally, as shown in Fig. 7, a larger opening portion u〇a may be formed from the opening region 150 to the lateral sealing portion 132. The sealing strength of the transverse sealing portion 132 is preferably 4 N/15 mm. When the sealing strength is less than < N/15 mm, the sealing loss may occur, and the sealing property may be lowered, or the pressure may be broken during the transportation and storage, and the bag may be broken, which is not preferable. When the sealing strength exceeds 7 5, the easy-opening property is not obtained and the tearing portion is left, which is not preferable. Moreover, the easy-opening package according to the present invention is compared with the conventional cohesive-peelable sealing layer. The above values can be obtained in a wider range of sealing conditions (temperature, time, pressure). As a result, it is possible to greatly reduce the incidence of defective products such as seal shedding or difficulty in opening the seal. As described in J, the package body can form an opening larger than the conventional one, and the male and the seal have an easy-opening property. The laminated film of the torn portion is easily removed. Therefore, it is suitable for use as a package in the following cases: ~, containing contents such as a wet tissue, such as a wet wipe, and a package and contents. A package with two small gaps, a large friction, and it is difficult to pull out the contents, or a small product such as a screw or candy, and a package that wants to take out most of the inner grain. The package 100 can be used separately. If it is used directly, the package body (10) can be further folded into the outer casing state, whereby even if the opening of the package body 100 is opened after opening, the contents can be protected again by the outer container. 103365.doc -18· 1278411 Hereinafter, the present invention will be described in detail by way of examples and comparative examples. <Example 1 >=The following specifications·· 12 μl/ink/adhesive/(iv) 6 μ/adhesive/easy peeling Membrane (1) 35 μ In this case, as an easy-release film (1) 35 μ, aroma τρ6 (trade name: manufactured by Rikou and Electric Plastics Co., Ltd.) is used.

The sealing temperature of the above 7 N/15 mm or less) is about 2 〇 ° C, which is quite wide. On the other hand, in Comparative Example 1 using a cohesive peeling type easily peelable film, it is known that the sealing temperature is 140 ° C. The strength is low, less than 4 N/15 mm, and the sealing property is not sufficient. The sealing strength of the sealing temperature of 160 °C exceeds 7 N/15', and the easy-opening property is not sufficient, so that the seal with easy opening and sealing can be achieved at the same time. The sealing temperature of the strength was limited to 150 ° C, and the range was narrower than that of Example 1. Further, in Comparative Example 2 using a patterned release varnish (using a composition in which the ink layer was peeled off), the sealing temperature was 120 ° C. The sealing strength has exceeded 7 N/15 mm, and CPP has not occurred in the peeled state. The roots were broken, and the easy-opening property could not be obtained. <Test Example 2 > The pillow-shaped package was formed by using the layered film of the first embodiment and the comparative examples 1 and 3, and the horizontal sealing portion was 103365.doc -20-1278411. The measurement of the sealing strength, the feeling of the hand peeling, and the peeling state were evaluated, and the results are summarized in Table 2 (Example 1) and Table 3 (Comparative Example 1). In addition, the pillow-shaped packaging system adopts a pleated pattern, and is formed into a longitudinal 104 mmx width 42 mm (length of the pleat edge of the elongated horizontal pleating portion) x height 18.5 mm, a sealing width of the longitudinal sealing portion of 8 mm, and an upper and lower transverse sealing portion. The sealing width was 5 mm (face seal), and the sampling of the test piece was as shown in Fig. 9. A strip-shaped slit having a width of 10 mm was provided on the horizontal seal portion on the upper surface of the package, and the test pieces 112 and 113 were respectively evaluated. Moreover, as shown in FIG. 9, the test piece 112 is sampled by the side of the vertical seal 190 which is not poured (the state of the two laminated film of the horizontal seal system or more), and the test piece 113 is the side which the vertical seal 140 fell. Two samples of the state of the two laminated films + vertical sealing portions of the horizontal sealing system are applied. On the other hand, in the test pieces 112 and 113 on the left and right sides, one of the higher values is the seal strength. Also, the numerical value is the average of n=4.

As a result of the results of Tables 2 and 3, in Example 1 in which the interlayer peeling type easily peelable film was used, it was found that the handle was good in a wide range of the sealing temperature of 120 ° C to 150 ° C, and the peeling state was also quite stable, and No sealing or breakage. On the other hand, in Comparative Example 1 in which the cohesive peeling type easy-peeling film was used, it was found that the sealing strength was insufficient at a sealing temperature of 120 ° C or lower, and the feeling was poor at 130 ° C or higher, and good results were not obtained. Easy to open. Further, in Comparative Example 3 in which the cohesive peeling type peeling film was similarly used, the hand feeling was good when peeled off by hand, but the sealing strength was insufficient at both sealing temperatures. [Industrial use The present invention is suitable for use as an easy-opening package which can easily take out the contents contained therein, for example, a package for carrying wet wipes.
