Description of the invention [Technical field to which the invention belongs] The present invention relates to the ease of handling, transportation, and quality assurance of a multi-liquid mixing type curable composition, and to reduce the volume at the time of disposal. Packaging bag for hardening composition. [Prior art] There are active energy ray-curable resist ink materials that are hardened by radiation, which supplies active energy by heat, infrared, visible light, ultraviolet, or electron rays. There is also a two-liquid mixed type curable composition which is hardened by mixing a main agent and a hardener. Other hardening compositions include adhesives, coatings, printing inks, and the like. These hardenable compositions take into account the tightness of preventing leakage of the contents, the prevention of the passage of gases such as the penetration of oxygen or water vapor or the release of solvents or volatile components, the resistance to outgassing, and the light-shielding properties to prevent the contents from deterioration. Handle in steel or plastic containers. The main agent and hardener of the two-liquid mixing type sclerosing composition are placed in individual containers. When it is used, it must be mixed after refilling the contents of either container into another container, or each time the contents are taken out from each container in a proportion measured in a predetermined ratio and mixed. Therefore, the work is tedious, which constitutes a main picture in which the work is greatly reduced. In addition, the empty containers of steel containers and plastic containers are heavy and bulky. In recent years, based on environmental concerns, weight reduction and volume reduction of empty containers after use have been demanded. (2) (2) 200404719 [Summary of the Invention] The packaging bag for a curable composition of the present invention stores two or more kinds of contents in a state separated from each other, and spit out the contents in one place. The packaging bag for the hardened composition is used to remove and mix the contents in a consistent operation. The sheet member forming the outer packaging of the packaging bag for the curable composition has at least one barrier layer in consideration of airtightness, light-shielding property, and anti-gassing property. This ensures that the quality of the hardenable composition during storage and transportation is stable, and prevents the content from leaking out during transportation. Because it is made of sheet members, it is lightweight and has a small volume of waste. A package for a curable composition according to the present invention includes a sheet member provided with at least one barrier layer, two or more storage chambers formed by overlapping and heat-sealing the sheet members, and a partition portion that partitions adjacent storage chambers. In addition, the storage room has a nozzle portion for taking out the contents stored in the peripheral portion which is folded with the partition as a boundary and overlaps each other in the state where the storage room is overlapped. The nozzle portion may be formed on the same side as one end portion of the partition portion. At least one of the storage chambers has a tapered shape with at least one side narrowed toward the front end of the nozzle portion. φ In the case where the nozzle portion is only provided in any one of the storage chambers, at least a part of the partition is peeled off to communicate with the adjacent storage chambers and take out the contents of each storage chamber. 'When the contents contain radical polymerizable ingredients, the storage room also stores air at the same time. The method of taking out the contents of each storage room of the bag containing the hardenable composition is provided with a folding step of folding the partition portion and overlapping the adjacent storage room; And the discharge step of squeezing out the contents enclosed in the -6-(3) (3) 200404719 storage room. The packaging bag for a hardenable composition according to another embodiment of the present invention may include: a packaging means having at least one barrier layer to store the contents; a partition means to partition the inside of the packaging means into a plurality of storage chambers; Dispensing means for collecting the contents of the storage room in one place. [Embodiment] Best Mode for Carrying Out the Invention With reference to Fig. 1, a packaging bag (hereinafter referred to as "packaging bag") 1 for a curable composition according to a first embodiment of the present invention will be described. As shown in Fig. 1, the packaging bag 1 has a shape in which the sheet member S is overlapped, and the outer peripheral portion 2 is sealed by heat sealing except for the injection port 6. Further, in the first figure, the packaging bag 1 has a partition portion 3 which is heat-sealed in the longitudinal direction along the width direction of the packaging bag 1 from the center slightly to the right portion '. The partition 3 partitions the inside of the packaging bag 1 into two storage rooms A 1 and A 2. In addition, in the figure, a portion which is heat-sealed in a state before the content injection is shown by a hatched line. Nozzle portions N] and N2 are formed in the lower portions of the storage chambers A1 and A2. The storage chambers A !, A2 are tapered toward both ends of the nozzle portions N !, N2, and narrow on both sides. The taper may be formed by at least one side of at least one of the storage chambers A! And A2 toward the nozzle portion. The tapered nozzle portions N 1 and N 2 are arranged at a partition including a boundary portion constituting the storage chambers A 1 and A 2. The folded portion D and its vicinity are outer peripheral portions 2 which overlap each other in the case of center bending. That is, the nozzle portions N! And R are arranged at approximately the same distance E from the bent portion D, respectively. The nozzle portions N] and N 2 are arranged on the same side as the end of the partition 3 in the zone (4) (4) 200404719. The front ends of the nozzle portions N! And N2 are heat-sealed by 1 and closed during the period when the contents are stored in the receiving room A] and A2. When taking out the contents, the front ends of the 13 shells N1 and N2 are cut off by cutting along a chain line in the figure. The nozzle portions n i and n 2 are arranged straight within a certain range from the front end, and even if they are cut at a position on the front side of the chain line C, they still have the same diameter. The injection port 6 of the outer peripheral portion 2 provided on the opposite sides of the nozzles N! And N2 is unpacked before the contents are put into each storage room A] and A2. After the contents are injected into the respective storage chambers A !, A :, the injection port 6 is hermetically sealed from the dotted line in the figure to the outside by heat sealing. The packaging bag 1 formed as described above is suitable as a container for containing a curable composition as a content. Specifically, a two-liquid mixed type resist ink composed of a main agent and a curing agent is used as a content, and the resist ink is stored. The main agent is charged into one storage room A !, and the hardener is charged into the other storage room a2. Next, a case where a two-liquid mixed type resist ink, which is a hardenable composition, is stored as an example, a method of taking out the contents stored in the packaging bag 1 will be described. In the case where the main agent and the hardener are taken out and used, the reclining section is performed with the folding section D between the storage room A i and the storage room A2 as the center, and the folding steps of the storage rooms A! And A 2 are overlapped. . Next, in a state where the nozzle portions 1 ^ and N2 of each of the storage chambers A1 and A2 are overlapped, the unsealing step of the front ends of the nozzle portions N] and N2 is cut along a chain line C shown in FIG. As described above, the nozzle portions N 1 and N 2 are unsealed in a concentrated state. After the unpacking step is performed, the unstacking step may be performed. Finally -8-(5) (5) 200404719 'Constantly apply the method of compressing the packaging bag 1 into the storage room A !, A 2 in an unfolded state, squeeze out the main agent and harden the storage room A !, A2 Ejection step. By performing the discharging step, the main agent and the hardener are discharged from the packaging bag 1 at substantially the same time. Since the extruded main agent and the hardener are discharged in one place through the nozzle portions N! And N2, the operation of changing the contents in the mixing container is simple. Since the main agent and the hardener are extruded simultaneously, the resist ink can be directly mixed. A packaging bag 1 for a curable composition according to a second embodiment of the present invention will be described with reference to Fig. 2. Structures having the same functions as those of the packaging bag 1 for the curable composition of the first embodiment are designated by the same reference numerals, and a description thereof will be omitted. In the packaging bag 1 shown in Fig. 2, the corner portion 7 formed on the outer peripheral portion 2 is rounded to such an extent that the sheet member S is not damaged even if it comes into contact with other packaging bags. Therefore, it is possible to prevent the corner portion 7 of the packaging bag 1 from damaging the sheet member S of the other packaging bag 1 during transportation or packing operation. The outer peripheral portion 2 is cut out to match the taper of the nozzle portions N! And N2. By forming in this way, it is also possible to prevent large unevenness in the outer peripheral portion 2 when the contents are loaded, and to reduce the amount of cutting of the sheet member S. Since the two outer sides of the nozzle portions N! And N2 are punched into different shapes, the positioning of the packaging bag 丨 when the two-liquid filling device for filling the packaging bag 1 with the main agent and the hardener can be oriented correctly. Direction setting packing bag 1. Therefore, it is possible to prevent the main agent and the hardening agent to be injected into the storage chambers A! And A2 from being injected from the opposite direction by mistake. The partition portion 3 provided between the tapered portions from the injection port to the storage chambers A !, A2 is formed thinner than the partition portion 3 provided between the tapered portion to the nozzle portion N !, and the front end. In addition, one edge of the partition portion 3 is linear from the front end side of the nozzle portions N! And N2 to the injection port side 6. -9- (6) (6) 200404719 Since the partition 3 is a portion where the sheet member S overlaps and is heat-sealed ', the strength is higher than the portion where only the sheet member S overlaps. Therefore, in the case where the folding step is performed, the bent portion is easily formed on the side where the edges of the partition portion 3 are all linear. That is, the bent portion is formed at a predetermined position. -The widths W and W2 of the storage rooms A! And A2 are determined by the weight mixing ratio of the main component and the hardener of the two-liquid. However, since the volumes of the storage rooms A! And A2 change with individual expansion adjustments, the width and W2 may not be directly proportional to the mixing ratio. ? Referring to Fig. 3, a description will be given of a packaging bag 1 for a curable composition according to a third embodiment of the present invention. Structures having the same functions as those of the packaging bag 1 for the curable composition according to the first or second embodiment are designated by the same reference numerals, and explanations thereof are omitted. The packaging bag 1 shown in FIG. 3 includes two compartments 3 and two storage rooms A1, A2, and A3 separated by the compartments 3. The nozzle portions N], N2, and N3 of each of the storage chambers A !, A2, and A3 are arranged side by side on the same side portion on the same side as the one end portion of each of the partition portions S. φ The nozzle portions N !, N2, and N3 are arranged around the bending portion D, and adjacent nozzle portions N! and N2, N2, and N3 are separated from the bending portion D and the bending portion D by the same distance L !, At L2. Therefore, when the folding steps are performed on the storage rooms A], A2, and A3, the nozzle portions A, N2, and N3 are overlapped with each other and concentrated in one place. -Therefore, by injecting the multi-liquid mixing type hardening composition that needs to be mixed in a predetermined ratio into the storage chambers A !, A2, and A3 in advance, and performing the folding step, unsealing step, and discharging step, not only the contents are squeezed out, but A multi-liquid mixing type curable composition having a desired mixing ratio is obtained. As a multi-liquid mixed type sclerosis -10- (7) (7) 200404719 composition is separately packaged in one of the contents of this packaging bag 1, there is a combination of a main agent, a hardener and a diluent. Referring to Fig. 4, a description will be given of a packaging bag 1 for a curable composition according to a fourth embodiment of the present invention. Structures having the same functions as the packaging bags for curable compositions according to the first to third embodiments are designated by the same symbols, and descriptions thereof are omitted. The packaging bag 1 shown in Fig. 4 has a partition 3 on the diagonal of the sheet member S forming a quadrangle. Storage room A], A2 are disposed on both sides of the partition 3, 6 nozzle portions N], N2 are disposed by folding the packaging bag 1 with the storage portion A1, A2 around the bending portion D as a center, overlapping each other s position. Since the packaging bag 1 is formed in a substantially square shape in this embodiment, the nozzle portions N1 and N2 are arranged at opposite angles different from the angle through which the bent portion D passes. Since the nozzle portions N 3 and N 2 are arranged at the corners of the sheet member S, the two sides of the storage chambers A! And A 2 to the nozzle portion% and 仏 are tapered. The nozzles &, N2 are straight to the tip. By cutting the front end along a chain line C in the figure, the nozzle portions N !, ^ are unsealed. The injection port 6 is formed on one side of the outer peripheral portion 2 and can be injected from a direction in which the filling device is aligned while simultaneously filling the contents. After the contents are filled, each of the storage chambers A! And A2 is hermetically sealed by a range enclosed by a dotted line except for the bent portion D in FIG. 4. Referring to Fig. 5, a packaging bag 1 for a curable composition according to a fifth embodiment of the present invention will be described. Structures having the same functions as those of the packaging bag 1 for the curable composition according to the first to fourth embodiments are designated by the same reference numerals.
於本實施形態中，第5圖所示包裝袋1僅於二收納室A I -11 - (8) (8)200404719 、A 2之一收納室A 1 置噴嘴部N 1。隔出收納室A 1、A 2的區 隔部3例如形成較其他實施形態的區隔部3細且弱的熱密封 狀態，俾易於剝離熱密封的薄片構件S。又由於在第5圖所 示包裝袋1中僅有一個噴嘴部N;，故無折彎部D。 如此形成的包裝袋，依如次順序取出分開包裝於收納 室A !、A2的內容物。首先，剝離區隔部3的一部份，使相鄰 收納室A !、A 2連通。於此情形，若考慮內容物的排出方向 ’即以剝離最接近噴嘴部N!的一側較佳。其次，沿一點鏈 線C切掉噴嘴部N!的前端。最後，壓潰包裝袋丨，擠出內容 物。藉此，裝入收納室A!的內容物與裝入收納室A2的內容 物於噴嘴部N!的上游合流，自噴嘴部Nl排出。 以上第1至第5實施形態的包裝袋是以具備包裝手段、 區隔手段及吐出手段的包裝袋爲代表的例子。包裝手段具有 至少一層阻擋層。阻擋層至少具有密閉性、遮光性、氣密性 中的任一種特牲。區隔手段將包裝手段的內部隔成複數收 納室。吐出手段將畜積於各收納室的內容物集中於一處取 出。 亦即’薄片構件S是一包裝手段例。區隔部3·是一區隔 手段例。於折彎包裝袋1狀態下相互重疊的噴嘴Νι、N2 ( 及N 3 )或僅设於收納室A !、A 2中一收納室的噴嘴部n i是一 吐出手段例。 又，用來製造包裝袋1的薄片材料s具有遮光性或抗滲 热性，並且，可錯由熱密封予以密封。因此，可爲能熱密 封之-合成樹脂薄片。於此情形了，合成樹脂薄片本身兼 -12- (9) (9)200404719 具阻擋層及密封劑層。爲了提高抗滲氣性、耐滲水性，使 用藉熔融或黏接具有不同特性的兩片以上的合成樹脂薄片 層疊的薄片材料作爲薄片構件S。 爲了提高遮光性’使用以鋁箔或鋁蒸鍍層等金屬薄膜 層夾在合成樹脂薄片間層疊的薄片材料作爲薄片構件。不 過，在使用前發現金屬薄膜層的龜裂情形下，最好可確認 龜裂所產生碎片是否成微小雜質攙入收納於收納室A !、A2 (及As )的內容物中。於此情形下，使用藉易剝離手段密 貼於密封劑層與阻擋層間的構造的薄片材料作爲薄片構件s 。密封劑層以可熱密封的合成樹脂形成。阻擋層具有至少 一金屬薄膜層。，易剝離手段以可用手剝離密封劑層及阻擋 層的黏接強度密貼密封劑層與阻擋層。 就可熱密封的合成樹脂列舉如次：聚烯（例如聚乙燒 、聚丙烯、聚戊烯等）；聚酯（例如聚對苯二甲乙二醋、 聚對苯二甲丁二酯等）；高分子量的熱可塑性樹脂（例如 聚醯胺）°這些合成樹脂可藉單一層或自由組合不同種類 層疊的複數層構成密封劑層。且，這些合成樹脂可在樹脂 合成時製成低、中、高密度或具有結晶性的物品。 於包裝袋1的薄片構件S需要UV (紫外線）阻擋層情 形下，可藉由添加具有紫外線遮蔽能力的物質，僅由單一 合成樹脂薄片製袋。又，藉由具備至少一層含有具有紫外 線遮蔽能力的物質層，可製作只有各種合成樹脂薄片的層 疊薄片。 具有紫外線遮蔽能力的物質可爲藉由吸收、反射、散 -13- (10) (10)200404719 射紫外線、遮蔽紫外線的透射的物質。例如，列舉之有氧 化鈦、氧化鋁、氧化矽、氧化鐵、鋅、碳酸鈣、碳酸鎂、 石墨等無機顏料（水楊酸衍生物、二苯基酮衍生物、培索 托利哩衍生物、氰基丙烯酸衍生物等）有機類紫外線吸收 劑。 易剝離手段有組合以減小層疊的合成樹脂間的黏接力 的方法。其他易剝離手段可爲局部塗覆黏接前於層疊面的 方法、調配矽等剝離劑於層疊用黏接劑或層疊的合成樹脂 層的方法。使用本身黏接力小的黏接力的方法、黏接劑的 塗覆量小的方法等。 考慮以上內容，.就用來作爲包裝袋1的薄片構件S的薄 片材料層疊構造而言，可舉如次構造爲一例子。密封劑層 與阻擋層以擠出聚乙烯介於其間層疊。並且，於擠出聚乙 婦層與密封劑層以及阻擋層的至少其中任一層間的界面設 有可容易對聚乙烯層剝離的合成樹脂層（下稱剝離層）。 可適用聚乙烯以外的聚烯、耐龍等聚醯胺、聚對苯二 甲二乙醋、聚對苯二甲丁二酯等聚酯以及其所形成的薄膜 作爲此剝離層。這些薄膜容易用來作爲一延伸即容易剝離的 層疊構件。特別是，雙軸拉伸聚對苯二甲二乙酯易於作成容 易剝離的層疊構件，又，強度亦優異，且價格低廉。：且，較 佳地，此剝離層不在擠出聚乙烯層間的界面側進行電暈處理 等密貼性增進處理。 另一方面，阻擋層包含至少一層金屬薄膜層。藉由設 置含有金屬薄膜層的阻擋層，添增或提高抗滲氣性及遮光 -14- (11) (11)200404719 性。因此，可防止硬化性組成物因紫外線等而聚合反應、 溶劑揮發以及其所引起的內容物凝膠化或變色、變色。 可使用鋁、鋼、鐵、銅、鎳、鋁等的箔片或蒸鍍層作 爲金屬薄膜層。基於廉價、遮光性優異的觀點，較佳的是以 鋁箔或鋁蒸鍍層作爲金屬薄膜層。 且，爲了使鋁箔等金屬薄膜層不露出最外部，設置保護 層作爲阻擋層的外層。可使用聚烯、聚酯、聚醯胺等作爲 保護層。其形成薄膜或薄片，一延伸即提高強度。聚酯防止 於搬運時損傷到鋁箔等金屬薄膜層的效果很優異。特別是， 於與鋁箔接觸面側設置聚酯層的效果很大。 藉由擠出層疊聚乙烯，可自剝離層剝離地黏接擠出聚乙 烯層於設在密封劑層及阻擋層的至少其中一層的剝離層上 。又，亦可提高薄片構件S的強度。 密封劑層及阻擋層預先單獨使用或適當倂用乾燥層壓 板或擠出層壓板，藉由周知方法層疊製造。於密封劑層及 阻擋層的至少其中一層上層疊剝離層。聚乙烯的擠出層疊 可容易藉由擠出層壓法或乾燥層壓法，於剝離層上進行。 包裝袋1的薄片構件S可剝離地層疊內面以可熱密封的 合成樹脂層製成的密封劑層，以及含有金屬薄膜層的阻擋 層。因此，於使用前發現在金屬薄膜層有彎曲痕跡或龜裂 情形，即使於搬運中或處理中，藉由直接剝離含有金屬薄膜 層的阻擋層，仍可容易確認金屬薄膜層的碎片等是否自裂 痕攙入內容物中。 且，爲了證實包裝袋1的性能，使用鋼罐或塑膠容器作 -15- (12) (12)200404719 爲外裝容器，隨意將複數個充塡硬化性組成物的包裝袋1塞 入其中'並輸送。結果，此包裝袋1並未發生薄片構件s剝 離或於薄片構件S開孔，確認其獲得充份安全性及強度。 作爲包裝袋1的薄片構件S使用的薄片材料的合計厚度 越厚，抗滲氣性、遮光性、耐磨損性即越優異。不過，在厚 度超過3 0 0 μ m (微米）情形下，由於薄片構件s會變硬，故 使用之有困難。又，相反地，在薄至30 μηι以下時，由於耐 磨損性及耐貫通性等低下，故易於在輸送中開孔。亦即，可 知在薄片構件S薄至30 μηι以下情形下或厚至300 μηι以上情 形下’不適於作爲收納抗蝕油墨等硬化性組成物的包裝袋 。因此’較佳地，薄片構件的厚度在30 μηι以上，3 00 μηι 以下。 金屬薄膜層的厚度越厚，抗滲氣性、遮光性及包裝袋 的強度越優異。不過，金屬薄膜層的厚度的上根顯然受到 薄片材料的合計厚度及薄片構件S的柔軟度限制。另一方 面’在金屬薄膜層的厚度薄至5 μπι以下情形下，容易在輸 送時，於金屬薄膜層本身穿孔（細孔）。 另外’藉由適當選擇薄片構件S各層的組合及厚度， 可提高包裝袋1的強度。 有時候’就內容物而言，於收納於包裝袋的硬北性組 成物之一 ’例如主劑中，含有自由基聚合性成份。藉由於 @ ^ Φ所含氧自由基，抑制因熱或紫外線等而於含有自由 基聚合性成份的材料發生的自由基反應。亦即，含有自由 基聚合性成份的材料藉由與空氣接觸，可妨礙材料中硬化 -16- (13) (13)200404719 性樹脂或單體成份的聚合，防止高分子化。 因此，若將含有自由基聚合性成份的內容物與空氣一 起充塡於包裝袋1的收納室A!(或A2內），即藉由氧的阻 礙’抑制自由基聚合性組成物的聚合。結果，於保管中， 自由基聚合性組成物（主劑）不會發生凝膠化，包裝袋1 可確保自由基聚合性組成物的長久穩定性。 就空氣量而言，相對於充塡的自由基聚合性組成物的 容量在1%以上可出現效果。不過，若超過50%，包裝袋1本 身的容積即增加，由於不適於綑包，故不佳。又，難以管理 數％的空氣量。於自包裝袋1的注入口 6使自由基聚合性組成 物流入收納室A !(或A 2 )之後熱密封外周部2情形下，空 氣量的範圍爲5%至30%。 如以上所說明，本發明硬化性組成物用包裝袋1可藉 由一次擠出作業，按預定比率取出複數液體。又”此後的 混合亦可藉由一貫作業，極平穩地進行。又，本發明的包 裝袋1的遮光性、抗滲氣性優異，可確保硬化性組成物的 長久穩定性，同時，可確保輸送時的安全性及品質。更由 於在包裝袋1使用後廢棄情形下，可將包裝袋1折成很小， 故體積不大，亦顧慮到環保。由於包裝袋1藉由重疊薄片 構件S並熱密封形成，故藉由壓平，可容易排出內容物。 亦即’由於殘留於收納室A!、A2、A3的量很少，故最適於 作爲抗蝕油墨或黏接劑、塗料、印刷油墨等硬化性組成物 的包裝袋。特別是，在符合混合比率收納多液混合型硬化 性組成物情形下，可提供於混合比率不會發生誤差的內容 -17- (14) (14)200404719In this embodiment, the packaging bag 1 shown in FIG. 5 is provided with the nozzle portion N 1 only in one of the two storage rooms A I -11-(8) (8) 200404719 and A 2. The partitions 3 separating the storage chambers A1 and A2 are, for example, formed into a thinner and weaker heat-sealed state than the partitions 3 of other embodiments, and the heat-sealed sheet member S is easily peeled off. Since the packaging bag 1 shown in Fig. 5 has only one nozzle portion N; there is no bent portion D. The packaging bags thus formed are sequentially taken out of the contents packed separately in the storage rooms A !, A2. First, a part of the partition portion 3 is peeled off so that the adjacent storage chambers A! And A2 communicate with each other. In this case, it is preferable to consider the discharge direction of the contents, that is, the side closest to the nozzle portion N! Next, the front end of the nozzle portion N! Is cut along a little chain line C. Finally, the packaging bag is crushed and the contents are squeezed out. Thereby, the contents loaded into the storage chamber A! And the contents loaded into the storage chamber A2 merge at the upstream of the nozzle portion N! And are discharged from the nozzle portion N1. The packaging bags of the first to fifth embodiments described above are representative examples of packaging bags provided with packaging means, partitioning means, and ejection means. The packaging means has at least one barrier layer. The barrier layer has at least any one of airtightness, airtightness, and airtightness. The partitioning means divides the inside of the packaging means into a plurality of receiving rooms. The ejection means collects the contents of the animals stored in each storage room in one place and takes them out. That is, the 'sheet member S is an example of packaging means. The segmentation section 3 · is an example of a segmentation means. The nozzles No, N2 (and N3) overlapping each other in the state of the folded packaging bag 1 or the nozzle portion n i provided only in one of the storage chambers A !, A2 are examples of the discharge means. The sheet material s used to make the packaging bag 1 has a light-shielding property or a heat-resistant property, and can be sealed by a heat seal by mistake. Therefore, it can be a heat-sealable synthetic resin sheet. In this case, the synthetic resin sheet itself has both a barrier layer and a sealant layer -12- (9) (9) 200404719. In order to improve the outgas resistance and water resistance, a sheet material laminated by fusing or bonding two or more synthetic resin sheets having different characteristics is used as the sheet member S. In order to improve the light-shielding property, a sheet material laminated with a metal thin film layer such as an aluminum foil or an aluminum vapor-deposited layer sandwiched between synthetic resin sheets is used as a sheet member. However, if cracks in the metal thin film layer are found before use, it is best to confirm whether the fragments generated by the cracks are incorporated into the contents of the storage rooms A !, A2 (and As) as minute impurities. In this case, a sheet material having a structure closely adhered between the sealant layer and the barrier layer by an easy peeling means is used as the sheet member s. The sealant layer is formed of a heat-sealable synthetic resin. The barrier layer has at least one metal thin film layer. The easy-to-peel means adheres the sealant layer and the barrier layer with the adhesive strength of the sealant layer and the barrier layer that can be peeled off by hand. The heat-sealable synthetic resins are listed as follows: polyolefins (such as polyethylene, polypropylene, polypentene, etc.); polyesters (such as polyethylene terephthalate, polyterephthalate, etc.) ; High-molecular-weight thermoplastic resins (such as polyamides) ° These synthetic resins can be used as a sealant layer by a single layer or by freely combining multiple layers of different types. In addition, these synthetic resins can be made into low, medium, high density or crystalline articles during resin synthesis. In the case where the sheet member S of the packaging bag 1 requires a UV (ultraviolet) blocking layer, it is possible to make a bag from only a single synthetic resin sheet by adding a substance having an ultraviolet shielding ability. Furthermore, by having at least one layer containing a substance having a UV shielding ability, a laminated sheet having only various synthetic resin sheets can be produced. The substance having ultraviolet shielding ability may be a substance that absorbs, reflects, and diffuses -13- (10) (10) 200404719 radiates ultraviolet rays and shields transmission of ultraviolet rays. Examples include inorganic pigments such as titanium oxide, aluminum oxide, silicon oxide, iron oxide, zinc, calcium carbonate, magnesium carbonate, and graphite (salicylic acid derivatives, diphenyl ketone derivatives, and pesotolide derivatives. , Cyanoacrylic acid derivatives, etc.) organic UV absorbers. The easy-peeling means is a method of combining to reduce the adhesive force between the laminated synthetic resins. Other easy-peeling means may be a method of partially coating the laminated surface before bonding, a method of preparing a release agent such as silicon to a laminating adhesive, or a laminating synthetic resin layer. A method using a small adhesive force by itself, a method of applying a small amount of adhesive, and the like are used. Taking the above into consideration, the structure of the sheet material used as the sheet member S of the packaging bag 1 may be a secondary structure as an example. The sealant layer and the barrier layer are laminated with an extruded polyethylene interposed therebetween. In addition, a synthetic resin layer (hereinafter referred to as a release layer) is provided at the interface between the extruded polyethylene layer, at least one of the sealant layer and the barrier layer, and the polyethylene layer can be easily peeled off. As the release layer, polyesters such as polyolefins other than polyethylene, polyamines such as nylon, polyethylene terephthalate, and polyterephthalate can be applied as the release layer. These films are easily used as laminated members which are easily peeled upon extension. In particular, biaxially-stretched polyethylene terephthalate is easy to form a laminated member that can be easily peeled off, and also has excellent strength and low cost. : And, preferably, the release layer is not subjected to adhesion improvement treatment such as corona treatment on the interface side between the extruded polyethylene layers. In another aspect, the barrier layer includes at least one metal thin film layer. By providing a barrier layer containing a metal thin film layer, the outgassing resistance and the light-shielding property are increased or improved -14- (11) (11) 200404719. Therefore, it is possible to prevent the curable composition from undergoing a polymerization reaction due to ultraviolet rays or the like, solvent volatilization, and gelation, discoloration, and discoloration of the contents caused by the polymerization reaction. As the metal thin film layer, foil, such as aluminum, steel, iron, copper, nickel, aluminum, or the like, can be used. From the viewpoint of being inexpensive and having excellent light-shielding properties, it is preferable to use an aluminum foil or an aluminum vapor-deposited layer as the metal thin film layer. In order to prevent the metal thin film layer such as aluminum foil from being exposed to the outermost, a protective layer is provided as an outer layer of the barrier layer. Polyolefin, polyester, polyamide and the like can be used as the protective layer. It forms a thin film or sheet and increases strength once stretched. Polyester is excellent in preventing damage to metal film layers such as aluminum foil during transportation. In particular, the effect of providing a polyester layer on the side in contact with the aluminum foil is great. By extruding the laminated polyethylene, the extruded polyethylene layer can be peelably adhered from the release layer to the release layer provided on at least one of the sealant layer and the barrier layer. Moreover, the strength of the sheet member S can also be increased. The sealant layer and the barrier layer are separately used in advance, or a dry laminate or an extruded laminate is appropriately used, and laminated by a known method. A release layer is laminated on at least one of the sealant layer and the barrier layer. Extrusion lamination of polyethylene can be easily performed on the release layer by extrusion lamination or dry lamination. The sheet member S of the packaging bag 1 is releasably laminated with a sealant layer made of a heat-sealable synthetic resin layer on the inside and a barrier layer containing a metal thin film layer. Therefore, before use, it is found that the metal thin film layer has bend marks or cracks. Even during transportation or processing, by directly peeling off the barrier layer containing the metal thin film layer, it is still easy to confirm whether the metal thin film layer fragments and the like Fissures dig into the contents. In addition, in order to confirm the performance of the packaging bag 1, a steel can or a plastic container is used as an outer container of -15- (12) (12) 200404719, and a plurality of the packaging bags 1 filled with a hardening composition are optionally stuffed therein. ' And delivered. As a result, no peeling of the sheet member s or openings in the sheet member S occurred in this packaging bag 1, and it was confirmed that it obtained sufficient safety and strength. The thicker the total thickness of the sheet material used as the sheet member S of the packaging bag 1 is, the more excellent the outgassing resistance, light shielding property, and abrasion resistance are. However, in the case where the thickness exceeds 300 μm (micrometers), the sheet member s becomes hard, so it is difficult to use it. On the other hand, when the thickness is as thin as 30 μm or less, wear resistance, penetration resistance, and the like are lowered, and therefore it is easy to make holes during transportation. That is, it is found that when the sheet member S is as thin as 30 μm or less or as thick as 300 μm or more, it is not suitable as a packaging bag for storing a hardening composition such as a resist ink. Therefore, it is preferable that the thickness of the sheet member is 30 μm or more and 300 μm or less. The thicker the metal thin film layer, the better the outgassing resistance, light-shielding property, and strength of the packaging bag. However, the upper root of the thickness of the metal thin film layer is obviously limited by the total thickness of the sheet material and the softness of the sheet member S. On the other hand, when the thickness of the metal thin film layer is as thin as 5 μm or less, it is easy to perforate (fine holes) in the metal thin film layer itself during transmission. In addition, by appropriately selecting the combination and thickness of the layers of the sheet member S, the strength of the packaging bag 1 can be increased. In some cases, 'for the contents, a radically polymerizable component is contained in one of the hard northern components contained in a packaging bag', for example, a main ingredient. Due to the oxygen radicals contained in @ ^ Φ, radical reactions that occur on materials containing free-radically polymerizable components due to heat or ultraviolet rays are suppressed. That is, a material containing a free-radical polymerizable component can prevent hardening of the material by contacting with air, thereby preventing the polymerization of a resin or a monomer component, thereby preventing polymerization. Therefore, if the contents containing the radically polymerizable component are filled with the air in the storage room A! (Or A2) of the packaging bag 1, the polymerization of the radically polymerizable composition is inhibited by the blockage of oxygen. As a result, the radically polymerizable composition (main agent) does not gel during storage, and the packaging bag 1 can ensure long-term stability of the radically polymerizable composition. The effect of the amount of air is 1% or more with respect to the capacity of the charged radically polymerizable composition. However, if it exceeds 50%, the volume of the packaging bag 1 itself increases, which is not suitable because it is not suitable for packing. In addition, it is difficult to manage an air amount of several%. When the radically polymerizable composition is flowed into the storage chamber A! (Or A 2) from the injection port 6 of the self-packing bag 1, the air volume ranges from 5% to 30%. As described above, the packaging bag 1 for a curable composition of the present invention can take out a plurality of liquids at a predetermined ratio by a single extrusion operation. Moreover, the subsequent mixing can also be performed very smoothly by consistent operation. In addition, the packaging bag 1 of the present invention is excellent in light-shielding properties and anti-gassing properties, and can ensure long-term stability of the hardening composition, and at the same time, can ensure Safety and quality during transportation. In addition, because the packaging bag 1 can be folded into a small size when it is discarded after use, the volume is not large, and environmental protection is also considered. Because the packaging bag 1 has an overlapping sheet member S And it is formed by heat sealing, so it can be easily discharged by flattening. That is, 'the amount remaining in the storage room A !, A2, A3 is very small, so it is most suitable as a resist ink or adhesive, paint, Packaging bags for hardening compositions such as printing inks. In particular, when a multi-liquid mixing type hardening composition is accommodated in accordance with the mixing ratio, it is possible to provide content that does not cause errors in the mixing ratio. -17- (14) (14) 200404719
