Description of the invention [Technical field to which the invention belongs] The present invention relates to a display bar, which is used for fixing and vertically arranging a plurality of bags containing goods for display. [Prior art] Generally, products such as snacks are sealed and sold using a pillow packing method (such as a vertical pillow type and a horizontal pillow type). In most cases, these bags containing merchandise are lined up and sold on store shelves. However, 'this method must manually place each bag on the display rack. The disadvantage of this method is that these bags can only be displayed on a specific display rack, so the position to be displayed is limited. A display and sales method that does not require a display rack is known, which is called a strip bag display method. As shown in FIG. 1, in the display state of the strip bag display method, many products are stuck on a tape member having a specific width, which is called a display strip, and hangs from each other. This display status makes it possible to display and sell goods everywhere-such as the side of a store checkout counter or the side of a restaurant counter-without the need for display racks. As for the conventional display strip, for example, an arrangement method is used in which a perforation process is performed on a tape made of paper or resin, and an adhesive tape is stuck on the back surface thereof, so that a bag containing a product is adhered to the adhesive tape through the perforation. In addition to this arrangement method, for example, other arrangement methods may be used in which a hook made of resin is affixed in advance to a predetermined position of a tape made of paper or resin, and a perforation is formed in the bag containing the commodity, In this way -4- (2) 200417466 hang the product in a relative position and stick it on it. However, these forms of display strips are difficult to automate the process of sticking bags containing merchandise to the display strips. Therefore, the strip bag display method is not widely used.
此處,已提出一種展示條,其中在一面上形成熱密封 層,如此可以直接熱密封裝有商品的袋子,並黏合於其上 。此種展示條之應用使得可以輕易地自動化進行將該裝有 商品的袋子黏貼於展示條,以及連續將商品包裝於該袋子 內之過程。Here, a display strip has been proposed in which a heat-sealing layer is formed on one side, so that a bag containing a product can be directly heat-sealed and adhered thereto. The application of such a display strip makes it easy to automate the process of attaching the bag containing the product to the display strip and continuously packaging the product in the bag.
將該裝有商品的袋子黏貼於此展示條過程必須以充分 密封強度進行,因此可以避免該袋子在商店展示期間因其 重力而自然掉落,或是避免輸送期間脫落。不過,若使用 高度密封強度將該裝有商品的袋子黏貼於該展示條,自該 展示條拆除該袋子時,該袋子的表層可能受損,傷及其印 刷囬’造成茼品外觀變差,而最糟的情況係,此種剝離現 象可能到達至密封部分以外之處,導致該用以維持商品品 質之袋子形成裂痕或是孔。 【發明內容】 本發明目的之一係提出一種展示條,其可以促使自動 化將該袋子黏貼於其上之過程,而且其可以在不損及外觀 之下拆除該裝有商品的袋子。 本發明有關一種展示條,其係用以固定並垂直排列許 多裝有商品的袋子,以供展示,其包含至少一層基材層與 -5- (3) (3)200417466 一層密封層,該密封層含有一種乙烯-醋酸乙烯酯共聚物 與一種促進黏著性膠黏劑。 在本發明展示條中,該表面可以藉由熱密封黏合於該 密封層,而且分開該密封層與藉由熱密封黏合之袋子表面 時,該剝離作用係在該密封層與該袋子表面間之界面發生 爲佳,施加低於該袋子表層抗斷強度極限之初始負重開始 該剝離作用,而且需要持續或間歇地施加相當於該初始負 重之負重,直到剝離作用完成爲佳。 上述乙烯-醋酸乙烯酯共聚物的醋酸乙烯酯含量係8 至42重量%爲佳。上述促進黏著性膠黏劑宜係至少一種 選自松香樹脂、萜烯樹脂、脂族烴樹脂、脂環烴樹脂與芳 族烴樹脂之樹脂。 上述密封層包括7 0至9 5重量%之乙烯-醋酸乙烯酯共 聚物與5至3 0重量%之促進黏著性膠黏劑爲佳。此外, 上述密封層在大致整體表面上形成爲佳。 上述基材層包括一種雙軸定向聚丙烯、雙軸定向聚對 苯二甲酸乙二酯、一種金屬箔、紙或其層壓製件爲佳。 設計本發明展示條,另外在該基材層與該密封層間形 成一層聚乙烯層爲佳。此種情況下,在一層包含乙烯-醋 酸乙烯酯共聚物與促進黏著性膠黏劑之膜以及一層雙軸定 向聚對苯二甲酸乙二酯膜之間擠出聚乙烯,進行層壓爲佳 ’或是將一層雙軸定向聚對苯二甲酸乙二酯膜層壓在該經 層壓膜(其包括一層含有乙烯-醋酸乙烯酯共聚物與促進黏 著性膠黏劑與一層聚乙烯層)的聚乙烯層上爲佳。 -6- (4) (4)200417466 該袋子最好包括至少一層密封層與一層基材層,該密 封層最好包括一層可熱密封雙軸定向聚丙烯膜。該密封層 與該基材層係經由膠黏劑層壓爲佳。該密封層與該基材層 係經由一層中間層層壓,而且該密封層與該中間層係經由 膠黏劑層壓。 本發明中亦包括一*種產品之展不法,其中藉由熱密封 黏貼本發明展示條與產品密封袋。 較佳體系 下列說明將詳細探討本發明。 本發明展示條包括至少一層基材層與一層密封層。 上述密封層包含一種乙烯-醋酸乙烯酯共聚物與一種 促進黏著性膠黏劑。上述乙烯-醋酸乙烯酯共聚物係一種 具有優良熱密封性質的樹脂,因此裝有商品的袋子表面可 以_囱熱密封處理黏合於該密封層。此外,由於該熱密封 處理係在約7 0至1 5 0 °C之較低溫下進行,所以可輕易地 加速該熱密封處理,即使該基材層厚度增加時,亦可以充 分進行該熱密封處理。藉由增加該基材層厚度,可以使整 體展示條更具彈性,即使藉由穿孔裝置等形成懸掛用之孔 時,仍然可以提高每個孔周圍的強度。 此外,由於上述乙烯-醋酸乙烯酯共聚物係一種彈性 彈性體,即使分開藉由熱密封處理黏合的袋子時,由於上 述密封層失效,故該袋子不會受損。 在習用展示條情況下,自該展示條移除藉由熱密封處 (5) (5)200417466 理黏貼於該展示條之裝有商品的袋子時,即使因爲該袋子 表面發生的黏合力失效時的衝擊造成該袋子的印刷層等受 損’因而使該袋子的印刷表面受損,該損傷可能到達密封 邰分以外的部分。反之,本發明展示條具有一種佈置,其 中該展示條側之密封層係由一種含有乙烯—醋酸乙烯酯共 聚物之材料形成;因此上述密封層比該袋子表面更容易撕 破’因此如圖2所示,當分開時,該剝離作用一定是在該 密封層與該袋子表面間之界面發生,拉伸並撕破該展示條 一側之密封層;因此,可以自該展示條移除該裝有商品的 袋子,並會使其外觀受損。 本發明展示條中,分開該袋子表面與該密封層時,施 加低於該袋子表層抗斷強度極限之初始負重開始該剝離作 用,而且直到該剝離作用完成爲止,需要連續或間歇地施 加與初始負重相當之負重爲佳。 本發明之發明人已分析藉由熱密封黏合於習用展示條 之袋子於剝離時受損的情況。然後發現,在許多袋子受損 實例中,測量於剝離該展示條與藉由熱密封黏合於其上之 袋子時所施加之負重,並將求得之値與介於該展示條與該 袋子間之距離(介於夾釺器間之距離)繪製成圖表,獲得具 有如圖5 a所示形狀之圖。如圖5 b所示,於剝離作用開始 階段(介於夾釺器間之距離:A ’),達到特定負重時,該袋 子上之表層最外面發生龜裂(此處該表層係指該袋子由2 至5層層壓膜所形成之外表面上之一層,藉由可熱密封雙 軸定向聚丙烯形成該袋子外表面情況下,不僅指最外表面 -8- (6) (6)200417466 上之可熱密封層,亦指該可熱密封雙軸定向聚丙烯層), 而且該破裂係自此點朝該表層裡面部分進行;因此被認爲 負重迅速降低,而且藉由非常微弱負重即可完成該剝離作 用(介於夾釺器間之距離:B1)。 反之,在本發明展示條之較佳模式中,測量於剝離該 展示條與藉由熱密封黏合於其上之袋子時所施加之負重時 ’並將形成之値與介於該展示條與該袋子間之距離(介於 夾釺器間之距離)繪製成圖表,可以獲得例如圖4a或4a, 所示形狀之圖。圖4b或圖4b’中顯示此時之剝離狀態的示 意圖。 換言之,由於該密封層包含該乙烯-醋酸乙烯酯共聚 物,以低於該袋子表層抗斷強度極限之初始負重開始剝離 (介於夾釺器間之距離:A),其中拉伸該密封層。藉由此 種佈置,由於該袋子側之表層沒有破損,因此可以移除該 裝有商品的袋子,不會使外觀受損。其次,最好提供一種 佈置,其中該剝離作用開始之後,連續或間歇地施加與初 始負重相當之負重,直到該剝離作周完成爲止(介於夾釺 器間之距離:B) 〇 爲了容易自該展示條移除商品,必須即使以較弱力道 駐能開始該剝離作用;不過,在習用展示條情況中,一旦 該剝離作用開始之後,該剝離作用所需之負重劇降,即使 於運送或展示該商品期間,瞬間於其上施加某一不強的負 重,該商品也很容易掉落。在本發明展示條之較佳模式中 ,由於必須自剝離作用開始直到完成期間連續或間歇地施 冬 (7) (7)200417466 加與初始負重相當之負重,所以可以避免商品意外脫落。 例如,可以藉由使本發明展示條之密封層包含一種乙 烯-醋酸乙烯酯共聚物,使得剝離作用在該袋子表面與該 密封層間之界面處發生,或是在損傷該袋子表面之前,該 密封層中發生黏合力失效;或者,當該密封層係由數層構 成時,提高該中間層黏合強度,如此不會發生中間層破裂 ,或者即使發生中間層破裂,除非施加相當大的負重,否 則該中間層破裂不會持續進行,達成上述佈置。 此處,該方法中,連續施加相當於初始負重之負重係 指於施加初始負重之後,完成該剝離作用所需之負重與初 始負重程度相同;不過,餘非猝然發生,否則可以容許該 負重比初始負重略增或略降。此處,連續施加在初始負重 ± 5 0%範圍內之負重爲佳。此外,使施加初始負重後,使 完成該剝離作用所需之負重隨夾釺器間之距離增加而提高 爲佳(圖4 a)。 此外,間歇性施加相當於初始負重之負重的方法係指 ,即使施加初始負重之後該負重大幅降低,可以大幅提高 完成該剝離作用爲止需要再次提高的負重,可以出現一尖 峰,其表示施加在初始負重± 5 0 %範圍內之負重(圖4 a ’)。 該乙烯-醋酸乙烯酯共聚物中之醋酸乙烯酯含量並無 特定限制,不過其設定在8至4 2重量%範圍內爲佳。該 含量低於8重量%,可能使得黏著性質不足,該含量超過 4 2重量%可能使該膜的模製性不足。 此外,至於該乙烯-醋酸乙烯酯共聚物,亦可使用其 - 10- 200417466 中一部分醋酸乙烯酯組份已進行皂化之此等共聚物。此外 ’至於該乙烯-醋酸乙烯酯共聚物,亦可使用其中一部分 經羧基改良之此等共聚物。 至於該乙烯-醋酸乙烯酯共聚物,可使用單一共聚物 ’或是可以混合方式使用兩種或以上具有不同醋酸乙烯酯 含量之此等共聚物。 至於上述促進黏著性膠黏劑,雖然其無特定限制,但 是例如使用選自松香樹脂、萜烯樹脂、脂族烴樹脂、脂環 烴樹脂與芳族烴樹脂其中至少一種樹脂爲佳。 至於上述松香樹脂,並無特定限制,其實例包括松香 、一種松香衍生物、松香酯、松香、木松香、妥爾油松香 、經蒸餾松香、經氫化松香、二聚物松香、聚合松香、天 然松杳之甘油酯、經改良松香之甘油酯、天然松香之季戊 四醇酯、經改良松香之季戊四醇酯、減色木松香之甘油酯 、經氫化松香之甘油酯、聚合松香之甘油酯、經氫化松香 之季戊四醇酯、松香之酚式改良季戊四醇酯。 至於上述萜烯樹脂,雖然無特定限制,但其實例包括 萜烯、酚萜烯、經改良萜烯與以―蒎烯共聚物_蒎烯共 聚物、雙戊烯聚合物與萜烯-酚共聚物。 至於上述脂族烴樹脂,雖然無特定限制,但其實例包 括:主要由具有4或 共聚 4或5個碳原子之單烯烴或二烯烴組成的The process of attaching the bag containing the product to the display strip must be performed with sufficient sealing strength, so that the bag can be prevented from falling naturally due to its gravity during display in the store or falling off during transportation. However, if the bag containing the product is adhered to the display strip using a high degree of sealing strength, the surface layer of the bag may be damaged when the bag is removed from the display strip, which will damage its printing and cause the appearance of the fake to deteriorate, In the worst case, this peeling phenomenon may reach beyond the sealed portion, causing cracks or holes in the bag used to maintain the quality of the product. [Summary of the Invention] One of the objects of the present invention is to provide a display strip that can promote the process of automatically attaching the bag to it, and it can remove the bag containing the commodity without compromising the appearance. The present invention relates to a display strip, which is used for fixing and vertically arranging a plurality of bags containing goods for display, and comprises at least one base material layer and a sealing layer of -5- (3) (3) 200417466, the seal The layer contains an ethylene-vinyl acetate copolymer and an adhesion promoting adhesive. In the display strip of the present invention, the surface can be bonded to the sealing layer by heat sealing, and when the sealing layer is separated from the surface of the bag bonded by heat sealing, the peeling effect is between the sealing layer and the surface of the bag. The interface is better. The initial load applied below the breaking strength limit of the surface layer of the bag starts the peeling effect, and it is necessary to continuously or intermittently apply a load equivalent to the initial load until the peeling effect is completed. The ethylene-vinyl acetate copolymer preferably has a vinyl acetate content of 8 to 42% by weight. The above-mentioned adhesion promoting adhesive is preferably at least one resin selected from the group consisting of rosin resin, terpene resin, aliphatic hydrocarbon resin, alicyclic hydrocarbon resin and aromatic hydrocarbon resin. The above-mentioned sealing layer preferably comprises 70 to 95% by weight of an ethylene-vinyl acetate copolymer and 5 to 30% by weight of an adhesion promoting adhesive. The sealing layer is preferably formed on the substantially entire surface. Preferably, the substrate layer includes a biaxially oriented polypropylene, a biaxially oriented polyethylene terephthalate, a metal foil, paper, or a laminate thereof. The display strip of the present invention is designed, and it is also preferable to form a polyethylene layer between the base material layer and the sealing layer. In this case, it is better to extrude polyethylene between a film containing an ethylene-vinyl acetate copolymer and an adhesion-promoting adhesive, and a biaxially oriented polyethylene terephthalate film, and laminate it. 'Or a biaxially oriented polyethylene terephthalate film is laminated on the laminated film (which includes a layer containing an ethylene-vinyl acetate copolymer and an adhesion promoting adhesive and a polyethylene layer) Polyethylene layer is preferred. -6- (4) (4) 200417466 The bag preferably includes at least one sealing layer and a substrate layer, and the sealing layer preferably includes a heat-sealable biaxially oriented polypropylene film. The sealing layer and the substrate layer are preferably laminated via an adhesive. The sealing layer and the substrate layer are laminated via an intermediate layer, and the sealing layer and the intermediate layer are laminated via an adhesive. The present invention also includes one of the most unsuccessful products, wherein the display strip and the product sealing bag of the present invention are adhered by heat sealing. Preferred System The following description will discuss the present invention in detail. The display strip of the present invention includes at least one substrate layer and a sealing layer. The sealing layer includes an ethylene-vinyl acetate copolymer and an adhesion-promoting adhesive. The above ethylene-vinyl acetate copolymer is a resin having excellent heat-sealing properties, so that the surface of a bag containing a product can be bonded to the sealing layer by a heat-sealing treatment. In addition, since the heat-sealing treatment is performed at a relatively low temperature of about 70 to 150 ° C, the heat-sealing treatment can be easily accelerated, and the heat-sealing can be sufficiently performed even when the thickness of the substrate layer is increased. deal with. By increasing the thickness of the substrate layer, the overall display strip can be made more flexible, and even when holes for hanging are formed by perforating devices, etc., the strength around each hole can still be increased. In addition, since the above ethylene-vinyl acetate copolymer is an elastic elastomer, even when the bonded bags are separated by heat-sealing, the bag is not damaged because the above-mentioned sealing layer fails. In the case of a conventional display strip, when removing a product-filled bag adhered to the display strip by heat sealing (5) (5) 200417466 from the display strip, even when the adhesive force on the surface of the bag fails The impact of the printed layer caused damage to the printed layer of the bag, and thus the printed surface of the bag was damaged, and the damage may reach parts other than the seal. In contrast, the display strip of the present invention has an arrangement in which the sealing layer on the side of the display strip is formed of a material containing an ethylene-vinyl acetate copolymer; therefore, the above-mentioned sealing layer is more easily torn than the surface of the bag. As shown, when separated, the peeling effect must occur at the interface between the sealing layer and the surface of the bag, stretching and tearing the sealing layer on one side of the display strip; therefore, the device can be removed from the display strip There are bags of merchandise that will damage its appearance. In the display strip of the present invention, when separating the surface of the bag from the sealing layer, an initial load below the breaking strength limit of the surface layer of the bag is applied to start the peeling effect, and until the peeling effect is completed, continuous or intermittent application and initial It is better to carry the equivalent weight. The inventor of the present invention has analyzed a case where a bag adhered to a conventional display strip by heat sealing is damaged when peeled off. It was then found that, in many examples of bag damage, the load applied when the display strip was peeled off and the bag adhered thereto by heat sealing was measured, and the calculated sum was between the display strip and the bag. The distance (the distance between the clamps) is drawn into a chart to obtain a figure with the shape shown in Figure 5a. As shown in Figure 5b, at the beginning of the peeling effect (the distance between the clamps: A '), when the specific load is reached, the outermost surface of the bag is cracked (here the surface layer refers to the bag) One layer on the outer surface formed by 2 to 5 layers of laminated film. When the outer surface of the bag is formed by heat-sealable biaxially oriented polypropylene, not only the outermost surface. -8- (6) (6) 200417466 The heat-sealable layer above also refers to the heat-sealable biaxially oriented polypropylene layer), and the cracking is from this point to the inner part of the surface layer; therefore, it is considered that the load is rapidly reduced, and by very weak load, that is, This peeling effect can be accomplished (distance between clamps: B1). Conversely, in a preferred mode of the display strip of the present invention, the load applied when peeling off the display strip and the bag adhered thereto by heat sealing is measured ', and the formed ridges are interposed between the display strip and the The distance between the bags (the distance between the clamps) is plotted as a graph, and a shape such as that shown in Fig. 4a or 4a can be obtained. The schematic diagram of the peeling state at this time is shown in Fig. 4b or Fig. 4b '. In other words, since the sealing layer contains the ethylene-vinyl acetate copolymer, peeling starts at an initial load below the breaking strength limit of the surface layer of the bag (the distance between the grippers: A), in which the sealing layer is stretched . With this arrangement, since the surface layer on the side of the bag is not damaged, the bag containing the product can be removed without damaging the appearance. Secondly, it is preferable to provide an arrangement in which a load equivalent to the initial load is continuously or intermittently applied after the peeling action is started, until the peeling week is completed (the distance between the clamps: B). The product removed by the display strip must start the stripping effect even with a weaker force; however, in the case of a conventional display strip, once the stripping effect starts, the load required for the stripping effect drops sharply, even during transportation or During the display of the product, a weak load is immediately applied to the product, and the product is also easily dropped. In a preferred mode of the display bar of the present invention, since the winter must be applied continuously or intermittently from the beginning of the peeling effect to the completion period (7) (7) 200417466 plus a load equivalent to the initial load, it is possible to prevent the product from falling off unexpectedly. For example, by making the sealing layer of the display strip of the present invention include an ethylene-vinyl acetate copolymer, peeling occurs at the interface between the surface of the bag and the sealing layer, or before the surface of the bag is damaged, the sealing Adhesion failure occurs in the layer; or, when the sealing layer is composed of several layers, the adhesive strength of the intermediate layer is increased so that the intermediate layer does not break, or even if the intermediate layer breaks, unless a considerable load is applied, otherwise This intermediate layer cracking does not continue, achieving the above arrangement. Here, in this method, the continuous application of a load equivalent to the initial load means that after the initial load is applied, the load required to complete the stripping effect is the same as the initial load; however, Yu Non suddenly occurs, otherwise the load ratio can be allowed. The initial load slightly increased or decreased slightly. Here, it is preferable to continuously apply a load within a range of ± 50% of the initial load. In addition, after the initial load is applied, it is better to increase the load required to complete the peeling effect as the distance between the clamps increases (Fig. 4a). In addition, the method of intermittently applying a load corresponding to the initial load means that even if the load is greatly reduced after the initial load is applied, the load that needs to be increased again before the completion of the peeling action can be greatly increased, and a spike can appear, which indicates that the load is applied at the initial time. Loads Loads in the range of ± 50% (Figure 4a '). The vinyl acetate content in the ethylene-vinyl acetate copolymer is not particularly limited, but it is preferably set in the range of 8 to 42% by weight. The content of less than 8% by weight may cause insufficient adhesive properties, and the content of more than 42% by weight may cause insufficient moldability of the film. In addition, as for the ethylene-vinyl acetate copolymer, those copolymers in which a part of the vinyl acetate component in -10-200417466 has been saponified can also be used. In addition, as for the ethylene-vinyl acetate copolymer, those copolymers in which a part of them are modified by a carboxyl group can also be used. As for the ethylene-vinyl acetate copolymer, a single copolymer 'may be used or two or more of these copolymers having different vinyl acetate contents may be used in a mixed manner. As for the above-mentioned adhesion-promoting adhesive, although it is not particularly limited, for example, at least one resin selected from the group consisting of rosin resin, terpene resin, aliphatic hydrocarbon resin, alicyclic hydrocarbon resin and aromatic hydrocarbon resin is preferably used. As for the above-mentioned rosin resin, there is no specific limitation, and examples thereof include rosin, a rosin derivative, rosin ester, rosin, wood rosin, tall oil rosin, distilled rosin, hydrogenated rosin, dimer rosin, polymerized rosin, natural Glycerol esters of turpentine, glycerides of modified rosin, pentaerythritol esters of natural rosin, pentaerythritol esters of modified rosin, glycerides of reduced wood rosin, glycerides of hydrogenated rosin, glycerides of polymerized rosin, glycerides of polymerized rosin, Pentaerythritol ester and phenolic modified pentaerythritol ester of rosin.

a resin made by polymerizing cyclic monomers such as cyclopentadiene, hydrogenated dicyclopentadiene resin, and hydrogenated petroleum resin. As for the above-mentioned aromatic hydrocarbon resin ', there is no particular limitation, and examples thereof include styrene, indene, a styrene copolymer and an? -Methylstyrene copolymer. As the above-mentioned adhesion-promoting adhesive, for example, a commercially available resin such as that disclosed in U S P No. 6 1 794 5 can be used. The above-mentioned sealing layer preferably includes 70 to 95% by weight of an ethylene-vinyl acetate copolymer and 5 to 30% by weight of an adhesion promoting adhesive. When the content of the above-mentioned adhesion-promoting adhesive is less than 5% by weight, the adhesiveness of the sealing layer during melting may be insufficient, and when it exceeds 30% by weight, its moldability may be insufficient. The above-mentioned sealing layer may contain a wax to improve the applicability of processing, and adjust the adhesive strength and the like. The amidine is not particularly limited, and for example, various amidines may be used, such as an olefin as a base wax, a paraffin as a base wax, an aliphatic ester as a base wax, a deoxy carnauba wax, a saturated aliphatic acid Is a base wax, an unsaturated aliphatic acid is a base wax, a saturated alcohol is a base wax, an aliphatic alcohol is a base wax, a polyol is a base wax, and a saturated fatty acid ammonium is a base wax 1. A saturated fatty acid bisphosphonium amine is used as a base wax, an unsaturated acid phosphonium amine is used as a base wax and an aromatic bisphosphonium is used as a base wax. If necessary, the above-mentioned sealing layer may contain common additives such as an anti-ultraviolet agent , Antioxidants, plasticizers, lubricants, pigments and dyes. -12- (10) (10) 200417466 The above-mentioned sealing layer may be formed substantially on the entire surface of the display strip of the present invention, which may form a stripe pattern, or may be formed only at a predetermined position where products are to be pasted. When the sealing layer is formed substantially on the entire surface of the display strip of the present invention, the product can be adhered to a desired position of the display strip, thereby providing a desired arrangement. In this case, the term "approximately" on the entire surface means a state that does not include the perforation processing position of the non-adhesive product and the surrounding parts. Although there is no specific limitation, because of the number of products attached to it and hanging, the above substrate layer is preferably designed to have sufficient strength and heat resistance so that it will not melt and deteriorate during heat sealing treatment; therefore, It is preferable to use, for example, a biaxially oriented polypropylene (OPP), a biaxially oriented polyethylene terephthalate, a metal foil, a laminate of paper and the like. Although there is no particular limitation, the thickness of the substrate layer is preferably set in a range of 30 to 2 00 pm. The thickness of less than 30 μm does not provide sufficient strength, which may cause damage to the bag when the bag containing the product is displayed or removed. However, the thickness of more than 200 μm may cause the substrate layer to become a thermal insulation material. Heat is not sufficiently transferred to the sealing layer during the sealing process. As mentioned above, because the ethylene-vinyl acetate copolymer contained in the sealing layer has better low-temperature heat-sealing properties, the thickness of the substrate layer can be increased within the range that does not interfere with the heat-sealing properties to improve the overall display strip. "Flexibility" Even when a hole for suspension is formed using a perforator or the like, the strength around each hole can be strengthened accordingly. In the display strip of the present invention, it is preferable that a polyethylene layer is additionally formed between the base material layer and the sealing layer. Because polyethylene has flexibility and high resistance to ductility, 'coating the polyethylene layer can improve the overall strength of the display strip of the present invention; because -13- (11) (11) 200417466 this' even if the suspension is formed by perforation treatment In the case of a hole in a display bar, when any display bar is removed, the corresponding position can withstand the load imposed on it. Here, the polyethylene layer can also be used as an adhesive material for bonding the base material layer and the sealing layer. When polyethylene is squeezed between the base material layer and the sealing layer, several layers of polyethylene can be laminated to perform the lamination treatment of polyethylene. In addition, in addition to polyethylene, an ethylene- (meth) acrylic acid copolymer or an ethylene- (meth) acrylic acid ionomer copolymer may be used. In addition, a conventional dry lamination method may be used to laminate these layers with an adhesive added between the above-mentioned substrate layer and the sealing layer, or a thermal lamination method may be used without using a solvent or an adhesive. These layers are laminated. Although not particularly limited, the thickness of the polyethylene layer is preferably set to 5 to 50 μm. The thickness of less than 5 μm may not provide sufficient strength, but the thickness of more than 50 fim will cause the thickness of the overall display strip to become thicker, and the heat sealing property will be deteriorated due to its thermal insulation effect. In the display strip of the present invention, the substrate layer and the sealing layer may further form other layers having other functions. As such a layer, for example, a printed layer can be proposed. In particular, when a polymer is used as the substrate layer, it is preferable to form the printed layer between the substrate layer and the sealing layer, and when paper is used as the substrate layer, the unlaminated surface of the paper is used. It is better to perform printing processing on it. The mode of the display bar of the present invention is not particularly limited, and examples thereof include a band shape and a sheet shape. In addition, perforation treatment can be performed, a hole can be formed on one end of the display bar, or the clip can be attached to the display bar, and the hole or clip can be put on a hook to hang and display the display bar with the product stuck. In particular, since this perforation process can be easily performed by an automated method, it is preferable to use this process -14- (12) (12) 200417466. However, in the case of opening a hole in the display strip and attaching a hook, excessive force may be applied to the hole portion to cause tearing, strengthen the substrate layer, or prepare a layer between the substrate layer and the sealing layer to form a polymer. The vinyl layer or the nylon layer is preferably arranged. As for the product-filled bag adhered to the display strip, any commonly used bag is suitable; it is preferable to use a bag including at least one sealing layer and a base material layer. The sealing layer on the surface of the bag is preferably formed of at least one compound selected from the group consisting of polypropylene, a copolymer of propylene and other olefins, a low-density polyethylene, and an ethylene-vinyl acetate copolymer. In addition, the sealing layer on the surface of the bag is preferably made of a heat-sealable biaxially oriented polypropylene (OPZ) film. The heat-sealable biaxially oriented polypropylene (ΟΡΗ) film generally refers to a film having a structure in which an extremely thin trimer layer is formed on the surface of the biaxially oriented polypropylene (OPP) to enhance the heat-sealing property. It is a material that has been widely used in Europe and the United States as a bag material, wherein the terpolymer layer is made of a resin having heat-sealing properties, such as a propylene-ethylene-butene terpolymer. Here, the sealing layer on the surface of the bag is preferably designed so as not to include the adhesive failure component. It is preferable that the sealing layer constituting the bag containing the commodity and the base material layer are laminated with an adhesive. Adhesive lamination provides a high degree of interlayer adhesion. Therefore, when the bag is removed from the display strip of the present invention, cracks will not occur between the layers of the bag, but the interface between the display strip and the bag or the inside of the display strip may be cracked. In addition, the sealing layer of the bag constituting the packaged product and the substrate layer may be laminated through an intermediate layer. In this case, it is preferable that the sealing layer and the intermediate layer are laminated through an adhesive. Laminating the sealing layer and the intermediate layer via an adhesive can provide a high degree of interlayer adhesion. Therefore, when the bag is removed from the display strip of the present invention, no breakage will occur between the layers of the bag, but the interface between the display strip and the bag or the inside of the display strip may rupture. A heat-sealing polymerization may be co-extruded And a polymer constituting the substrate layer, or a heat-sealable polymer (such as a hot-melt adhesive) is coated on the substrate layer to make the bag containing the product. As for the product-filled bag adhered to the display strip of the present invention, examples thereof include, for example, a material having a biaxially oriented polypropylene (0PP) layer / printing layer / adhesive layer / polyethylene (PE) layer / aluminum vapor deposited polyparaphenylene Ethylene diformate (1 > £) layer / polyethylene (PE) layer / cast polypropylene (CPP) layer structure; bag with biaxially oriented polypropylene (OPP) layer / printing layer / polyethylene ( PE) layer / aluminum vapor deposition polyethylene terephthalate (PET) layer / polyethylene (PE) layer / polypropylene (CPP) layer structure bag; with biaxially oriented polypropylene (〇pp) layer / Printed layer / aluminum vapor deposited cast polypropylene (CPP) layer structure bag; with biaxially oriented polypropylene (OPP) layer / printed layer / polyethylene (PE) layer / aluminum vapor deposited cast polypropylene (c PP) bag with layer structure; bag with transparent vapor deposition biaxially oriented polyethylene terephthalate (PET) layer / printed layer / cast polypropylene (CPP) layer structure; with heat-sealable biaxially oriented Polypropylene (〇pH) layer / printed layer / polyethylene (PE) layer / Ming vapor deposition heat-sealable biaxially oriented polypropylene (〇p pj) layer structure bag; Heat-sealed biaxially oriented polypropylene (0PH) layer / printed layer / polyethylene (PE) layer / aluminum vapor deposited cast polypropylene (cpp) layer structure 'and a bag having a heat-sealable biaxially oriented polypropylene (〇 p H) layer / printing layer / -16- (14) (14) 200417466 Adhesive layer / polyethylene (PE) layer / aluminum vapor deposition cast polypropylene (CPP) layer structured bag. There is no particular limitation on the method of manufacturing the display strip of the present invention, and a conventional method can be used. For example, a method is proposed in which a base material layer separately manufactured by an extrusion molding method or the like and the sealing layer are adhered to each other by an adhesive. In addition, the above-mentioned sealing layer may be formed using a coating method. The method of forming the sealing layer by a coating method is not particularly limited, and for example, a method of laminating a hot-melt adhesive containing an ethylene-vinyl acetate copolymer and an adhesion-promoting adhesive on the substrate layer can be used. . Here, when a biaxially oriented polyethylene terephthalate film, a biaxially oriented polypropylene film, or the like suitable for coating treatment is used as a substrate layer, it is better to perform two types of pretreatment, such as corona treatment and coating It is better to undercoat, or to pre-laminate a polyethylene layer on the substrate layer. In addition, when forming the above polyethylene layer, it is best to use a layer containing an ethylene-vinyl acetate copolymer A method for forming polyethylene with biaxially oriented polyethylene terephthalate film and extruding between these films, and a multilayer film made from an ethylene-vinyl acetate copolymer and a polyethylene layer Method for laminating biaxially oriented polyethylene terephthalate salt on a polyethylene layer. In addition, when the above-mentioned sealing layer is made of several layers including a release layer and a heat-sealing layer, a co-extrusion die can be used. This method forms this layer. As for the method of attaching a bag containing a product to the display strip of the present invention, although there is no particular limitation, it is preferable to use a sequence of the adhesive treatment such as that shown in FIG. In this method, 'the surface side of the bag containing the goods is first brought into contact with the display strip of -17- (15) (15) 200417466, and the upper part of the bag is heat-sealed to make it adhere to the display strip (Figure 6 a). After a predetermined number of bags containing goods are bonded to the display bar, the heat-sealed portion is used as an axis, and each bag containing the goods is turned upside down, so that the surface of each bag faces away from the display bar (Figure 6b) . In this state, one end of the display bar is put on a hook, etc., and the bag is hung from the hook to display the bag; thus, the adhesive part between the bag and the display bar is in the state shown in FIG. 6c. Therefore, even if The bag containing the product can also be easily pulled from the display bar with a small amount of force. The sealing strength between the bag and the display strip is not particularly limited, but it is preferably 1 to 50 N / 3 0 mm. If the strength is less than 1 N / 30 mm, the bag containing the product will fall due to the gravity of the weight of the product. If the strength is greater than 50 N / 3 0 mm, even if the bag is suspended It is difficult to drop the bag when it is pulled down. More preferably, the seal strength is from 5 to 30 N / 30 hi m. Disadvantages, the sealed state and the separated state between the bag and the display strip may vary greatly depending on the sealing conditions. In addition to the temperature, sealing pressure, and replacement of the sealing jig during sealing, the sealing conditions will also change depending on the shape of the sealing jig. As for the shape of the sealing jig, the shape shown in Fig. 7 can be used, for example. Therefore, it is better that the adhesive component forming the sealing layer and the material of the surface layer of the bag of the display strip of the present invention are optimally and selectively sealed. As for the sealing clamp I ^ ', it is determined according to the required width of the containing surface between the display strip and the surface of the bag. When the bag is removed from the display strip, the length substantially determines # 7 _ away from the action to the peeling The distance the effect is completed. -18- (16) 200417466 By applying the display strip of the present invention, the bag containing goods can be fixed by heat sealing, and a large number of goods can be easily and automatically adhered thereto. In addition, when the bag containing the goods is separated from the display, the peeling effect occurs at the interface between the sealing layer and the surface of the bag, and the sealing layer on one side of the display strip is stretched and torn; Therefore, no damage is caused to the appearance of the bag.
