Description

混合熱熔膠及蠟以封合側邊之紙板 Mix hot melt adhesive and wax to seal the side cardboard

本創作係一種混合熱熔膠及蠟以封合側邊之紙板,尤指在紙板之間隔空間中,由內而外依序填充一黏合材料及一密封材料,以形成具防水性之一封邊結構,該黏合材料及密封材料皆由熱熔膠及蠟混合而成,但該黏合材料之黏性係大於該密封材料,能形成具複數個孔隙之黏合層,該密封材料則能填滿該黏合層上的孔隙,以形成水密效果,防止水氣浸濕該紙板。 This creation is a kind of mixed hot melt adhesive and wax to seal the side of the cardboard, especially in the space of the cardboard, sequentially filling an adhesive material and a sealing material from the inside to the outside to form a waterproof one. The edge structure, the adhesive material and the sealing material are all mixed by a hot melt adhesive and a wax, but the adhesive material has a viscosity greater than the sealing material, and can form an adhesive layer having a plurality of pores, and the sealing material can be filled. The pores on the adhesive layer form a watertight effect to prevent moisture from wetting the paperboard.

按,瓦楞紙(Corrugated Fiberboard,又稱瓦通紙、紙皮)係一種應用極為廣泛之紙材,其結構係在兩層平面的「面材」(多為牛皮紙)間,設置一層波浪狀之「芯材」,由於整體結構中有60%~70%的體積為中空,故具有良好的減震性能,十分適合應用於製作紙箱。此外,瓦楞紙箱(Corrugated box)尚具有低成本、易加工、便於印刷、可回收、空箱重量輕等優良特點,因此,已成為目前貨運中紙箱的主要材料。 Corrugated Fiberboard (also known as corrugated paper, paper) is an extremely widely used paper. Its structure is in a two-layer "face" (mostly kraft paper) with a wavy pattern. The core material has a good shock absorption performance because it has a hollow volume of 60% to 70% in the overall structure, and is very suitable for use in making cartons. In addition, Corrugated box has the characteristics of low cost, easy processing, easy printing, recyclable, and light weight of the empty box. Therefore, it has become the main material of the carton in the current freight.

雖然瓦楞紙箱具有上述眾多優點,但亦存在有應用上的缺陷,即缺乏「抗濕性」,一旦瓦楞紙箱吸附到水氣,其結構強度將會快速降低,而很容易破裂。由於,在運送海鮮或生鮮食品等貨物時,貨物表面或多或少會存有水漬或水氣,且一般的瓦楞紙箱保溫性不高,在運送時間較 長時,海鮮更會因為逐漸回溫,或因為紙箱內外的溫度差,而在紙箱的內外表面凝結出更多水滴,致使瓦楞紙箱在送達目的地後,貨運人員一移動該瓦楞紙箱,瓦楞紙箱即容易因為結構強度已大幅降低,而在搬運過程中破裂(collapse),致使內部貨物散落而出。 Although corrugated boxes have many of the above advantages, there are also application defects, namely lack of "wet resistance". Once the corrugated box is adsorbed to moisture, its structural strength will rapidly decrease and it will easily break. Because when transporting goods such as seafood or fresh food, the surface of the goods will have more or less water or moisture, and the general corrugated box is not high in heat preservation. For a long time, seafood will gradually condense more water on the inner and outer surfaces of the carton because of the gradual warming, or because of the temperature difference between the inside and outside of the carton. After the corrugated carton is delivered to the destination, the freighter moves the corrugated box and corrugated box. That is, it is easy to collapse due to the structural strength, and the internal cargo is scattered.

為了解決前述「抗濕性」之問題,傳統的解決方法,係在瓦楞紙箱的內側面上塗佈一層蠟液(wax),以形成防水層、增加抗濕性,但此一作法並不完善,請參閱第1圖所示,係一瓦楞紙板1的結構示意圖(瓦楞紙板1可透過摺合,形成紙箱,故在此僅以局部示意圖,說明瓦楞紙板1的結構),該瓦楞紙板1包括二面材11、12及一芯材13,其中一面材11之外側面上可塗佈有蠟液,形成防水層14,以在該瓦楞紙板1被折合成紙箱後,該防水層14能防止水漬或水氣浸濕該瓦楞紙板1。 In order to solve the aforementioned problem of "moisture resistance", the conventional solution is to apply a wax on the inner side of the corrugated box to form a waterproof layer and increase moisture resistance, but this method is not perfect. Please refer to FIG. 1 , which is a structural diagram of a corrugated cardboard 1 (corrugated cardboard 1 can be folded to form a carton, so the structure of the corrugated cardboard 1 is only partially shown here), and the corrugated cardboard 1 includes two The surface materials 11, 12 and a core material 13, wherein the outer side of the one side material 11 can be coated with a wax liquid to form a waterproof layer 14 for preventing water after the corrugated cardboard 1 is folded into a carton. The corrugated cardboard 1 is wetted by water stains or moisture.

然而,由於該瓦楞紙板1中的芯材13並未被蠟液保護,因此,在該瓦楞紙箱位於一高濕度環境(high moisture environments)中時,水氣仍會從該瓦楞紙板1之側邊滲入芯材13或面材11、12之內側面,破壞該瓦楞紙板1之結構強度。請參閱第1圖所示,該瓦楞紙板1上平行於其楞向(即,芯材13波浪狀的延伸方向)之一側邊形成有一側邊開口101(又稱橫面cross section),而該瓦楞紙板1上垂直於其楞向之另一側邊則形成有一楞向開口102(又稱縱面longitudinal section),由圖式可清楚看出,該側邊開口101內並未具備一平面(而是被芯材13之波浪狀所隔開的空隙組成),因此,根本不可能塗佈蠟液,以形成防水層14。 However, since the core material 13 in the corrugated cardboard 1 is not protected by the wax liquid, the moisture will still be from the side of the corrugated cardboard 1 when the corrugated cardboard box is placed in a high humidity environment. The inner side of the core material 13 or the face materials 11, 12 is infiltrated to destroy the structural strength of the corrugated cardboard 1. Referring to FIG. 1 , a side opening 101 (also referred to as a cross section) is formed on one side of the corrugated cardboard 1 parallel to its twist direction (ie, the direction in which the core material 13 is wavy). The corrugated cardboard 1 has a lateral opening 102 (also referred to as a longitudinal section) perpendicular to the other side of the slanting direction. As can be clearly seen from the drawing, the side opening 101 does not have a plane. (But it is composed of voids separated by the wavy shape of the core material 13), and therefore, it is impossible to apply the wax liquid at all to form the waterproof layer 14.

此外,由於該芯材13尚會吸附蠟液,因此,就算業者勉強在該側邊開口101上塗佈蠟液,蠟液亦會滲入該芯材13內,而無法在側邊開口 101上形成防水層,意即,「側邊開口101會形成防水漏洞」的問題,並無法單純地透過「塗佈蠟液」的方式來解決。目前,若業者有生產高耐濕性之瓦楞紙箱的需求,則業者必須將整塊瓦楞紙板1浸入(submerge)蠟液中,使該瓦楞紙板1吸附足夠的蠟液,始能確保水氣不會由側邊開口101,浸濕瓦楞紙板1。然而,如此一來,不僅會大幅增加瓦楞紙箱的生產成本(至少增加兩倍),且重量亦會大幅上升(約增加50%),並不符合業者的需求。 In addition, since the core material 13 still adsorbs the wax liquid, even if the operator barely applies the wax liquid to the side opening 101, the wax liquid will penetrate into the core material 13 and cannot be opened at the side. A waterproof layer is formed on the 101, which means that the "side opening 101 forms a waterproof leak" and cannot be solved simply by "coating the wax liquid". At present, if the manufacturer has a demand for a corrugated box that produces high moisture resistance, the manufacturer must immerse the entire corrugated cardboard 1 in the wax liquid, so that the corrugated cardboard 1 adsorbs enough wax liquid to ensure the moisture is not obtained. The corrugated cardboard 1 is wetted by the side opening 101. However, this will not only significantly increase the production cost of corrugated boxes (at least two times), but also increase the weight (about 50%), which does not meet the needs of the industry.

由前述說明可知,時下的瓦楞紙箱,難以同時兼顧「抗濕性」及「材料成本」,若欲完善的在紙箱上形成防水層,則需要使用過多的蠟,且會增加重量,並非一適合的解決手段。此外,創作人尚發現,即便透過蠟液形成防水層,但由於蠟液不具「保溫性」,因此,在運輸貨物時,仍有著保溫上的問題。例如:在長途運送時,海鮮、生鮮食品(如:肉類、奶製品)會因為溫度上升而腐敗(即,保冷性不足)、而若是紅酒、花卉或藥品等貨物,無論是溫度過高或過低,皆會產生負面影響(即,缺乏恆溫效果)。 As can be seen from the above description, it is difficult to simultaneously consider both "moisture resistance" and "material cost" in a corrugated box. If a waterproof layer is formed on a carton, it is necessary to use too much wax and increase the weight. The right solution. In addition, the creator has found that even if the water-repellent layer is formed by the wax liquid, since the wax liquid does not have "insulation", there is still a problem of heat preservation when transporting the goods. For example, in long-distance transportation, seafood, fresh foods (such as meat, dairy products) will be corrupted due to rising temperatures (ie, insufficient cold retention), and if the goods are red wine, flowers or medicines, whether the temperature is too high or too Low, both have a negative impact (ie, lack of constant temperature effect).

因此,如何針對習知之瓦楞紙板1進行改良,設計出一種易於實施及能控制原料成本的方式,封閉住該瓦楞紙板1的側邊開口101,以有效提昇其抗濕性,同時,尚能同時提昇瓦楞紙板1的保溫性、甚至是改善隔音、耐衝擊等功能,即成為本創作在此亟欲解決的重要課題。 Therefore, how to improve the corrugated cardboard 1 of the prior art, design a method that is easy to implement and can control the cost of the raw material, and close the side opening 101 of the corrugated cardboard 1 to effectively improve the moisture resistance thereof, and at the same time, simultaneously Enhancing the thermal insulation of corrugated cardboard 1 and even improving the functions of sound insulation and impact resistance have become an important issue that this creation is intended to solve.

有鑑於習知瓦楞紙板作成紙箱後,由於其側邊開口無法透過蠟形成防水層,致使業者必須將整塊瓦楞紙板浸泡至蠟液中,以較高成本始能生產出防水瓦楞紙的問題,創作人憑藉多年來的實務經驗,經過多次 的研究、測試與實做後,終於設計出本創作之一種混合熱熔膠及蠟以封合側邊之紙板,期能有效解決習知技術之缺憾。 In view of the fact that corrugated cardboard is used as a carton, the side opening cannot pass through the wax to form a waterproof layer, so that the manufacturer must soak the whole corrugated cardboard into the wax liquid to produce the waterproof corrugated paper at a relatively high cost. People have relied on years of practical experience and many times After research, testing and implementation, I finally designed a hybrid hot melt adhesive and wax to seal the sideboard, which can effectively solve the shortcomings of the prior art.

本創作之一目的,係提供一種混合熱熔膠及蠟以封合側邊之紙板(如:瓦楞紙),該紙板至少包括一第一層面材、一第二層面材及一中間芯材,該中間芯材係設於該等面材之間,且其頂面及底面與該等面材間能分別形成至少一間隔空間,該等面材之對應側緣間分別形成有一側邊開口,該側邊開口係與該間隔空間相連通,該紙板之特徵在於,該間隔空間內設有一封邊結構,該封邊結構能密封(seal)該側邊開口,包括一黏合材料及一密封材料,該黏合材料係由熱熔膠及蠟混合而成,其中熱熔膠之重量百分比係佔該黏合材料之10%~65%之間;該黏合材料係填充於該間隔空間內,以將該等面材及中間芯材黏結成一體,該黏合材料能在固化後形成一具複數個孔隙之黏合層;該密封材料係由熱熔膠(可由多種不同熱熔膠混合)及蠟混合而成,其中熱熔膠之重量百分比係佔該密封材料之5%~40%之間,且該密封材料中熱熔膠的重量百分比係小於該黏合材料中熱熔膠的重量百分比,使該密封材料之黏性小於該黏合材料之黏性;該密封材料係填充至該黏合層上,以能填滿該黏合層上對應該側邊開口之該等孔隙,形成一防水的密封層。如此,藉由該熱熔膠「黏性」及「不被中間芯材吸收」的特性,該黏合材料即能在該側邊開口內形成一支撐用之黏合層,供塗佈該密封材料,以密封住該側邊開口,令業者無須使用大量地蠟液浸泡紙板,亦能有效提昇該紙板之抗濕性。 One of the purposes of the present invention is to provide a mixed hot melt adhesive and wax to seal the side of the paperboard (eg, corrugated paper), the paperboard comprising at least a first layer material, a second layer material and an intermediate core material. The intermediate core material is disposed between the surface materials, and at least one space is formed between the top surface and the bottom surface and the surface materials, and a side opening is formed between the corresponding side edges of the surface materials. The side opening is in communication with the space. The paperboard is characterized in that the space is provided with a side structure, and the edge structure can seal the side opening, including an adhesive material and a sealing material. The adhesive material is a mixture of hot melt adhesive and wax, wherein the weight percentage of the hot melt adhesive is between 10% and 65% of the adhesive material; the adhesive material is filled in the space to be The surface material and the intermediate core material are bonded together, and the bonding material can form an adhesive layer with a plurality of pores after curing; the sealing material is formed by mixing hot melt adhesive (mixed by a plurality of different hot melt adhesives) and wax. Among them, the weight percentage of hot melt adhesive is Between 5% and 40% of the sealing material, and the weight percentage of the hot melt adhesive in the sealing material is less than the weight percentage of the hot melt adhesive in the adhesive material, so that the adhesiveness of the sealing material is less than the viscosity of the adhesive material; The sealing material is filled onto the adhesive layer to fill the pores of the adhesive layer corresponding to the side openings to form a waterproof sealing layer. Thus, the adhesive material can form a supporting adhesive layer for coating the sealing material in the side opening by the characteristics of the "adhesive" and "not absorbed by the intermediate core material". In order to seal the side opening, the manufacturer can effectively improve the moisture resistance of the paperboard without using a large amount of wax liquid to soak the paperboard.

本創作係一種混合熱熔膠及蠟以封合側邊之紙板,請參閱第2及3A圖所示,係本創作之第一較佳實施例,該紙板2至少包括一第一層面材21(如:牛皮紙)、一第二層面材22及至少一中間芯材23,該中間芯材23係設於該等面材21、22之間,且呈彎折或彎曲狀(以瓦楞紙為例,中間芯材23可由一~三層的波浪紙材疊加構成),使其頂面及底面與該等面材21、22間能分別形成至少一間隔空間20,該等面材21、22之對應側緣間分別形成有一側邊開口201,該間隔空間20係與該側邊開口201相連通。 The present invention is a combination of a hot melt adhesive and a wax to seal the side of the paperboard. Referring to Figures 2 and 3A, in a first preferred embodiment of the present invention, the paperboard 2 includes at least a first layer 21 (eg kraft paper), a second layer material 22 and at least one intermediate core material 23, the intermediate core material 23 being disposed between the surface materials 21, 22 and being bent or curved (taking corrugated paper as an example) The intermediate core material 23 may be formed by stacking one to three layers of wavy paper, so that at least one space 20 can be formed between the top surface and the bottom surface and the surface materials 21 and 22, and the surface materials 21 and 22 are respectively formed. A side opening 201 is formed between the corresponding side edges, and the space 20 is in communication with the side opening 201.

本創作係在該間隔空間20內設有一封邊結構3,以密封該側邊開口201,該封邊結構3包括一黏合材料31及一密封材料32,該黏合材料31係由熱熔膠及蠟混合而成,其中,熱熔膠可為低密度聚乙烯(LDPE,Low Density Polyethylene)、乙烯-醋酸乙烯共聚物(Ethylene Vinyl Acetate,EVA),但並不以此為限,且亦可混合多種熱熔膠;蠟則可為微晶軟蠟、全精煉蠟,同樣亦不以此為限。為便於分辨,在第2~3C圖中,係以斜線、格狀及點狀來區別不同之防水材料(即,三者內含的蠟液比例不同),本案的核心特點,係利用熱熔膠的「黏性」及「不被中間芯材23吸收」的特性,搭配具「防水性」之蠟液,形成該封邊結構3,故,熱熔膠及蠟的原料可依 業者需求任意調整。 The present invention is provided with a side structure 3 in the space 20 for sealing the side opening 201. The edge structure 3 includes an adhesive material 31 and a sealing material 32. The adhesive material 31 is made of hot melt adhesive and The wax is mixed, wherein the hot melt adhesive can be Low Density Polyethylene (LDPE) or Ethylene Vinyl Acetate (EVA), but not limited thereto, and can also be mixed. A variety of hot melt adhesives; waxes can be microcrystalline soft wax, fully refined wax, also not limited to this. In order to facilitate the resolution, in the 2nd ~ 3C figure, the different waterproof materials are distinguished by oblique lines, lattices and dots (that is, the ratio of the wax liquid contained in the three is different). The core feature of the case is the use of hot melt. The "stickiness" of the glue and the "not absorbed by the intermediate core material 23" are matched with the wax liquid having "water repellency" to form the edge sealing structure 3. Therefore, the raw materials of the hot melt adhesive and the wax can be The industry needs to adjust arbitrarily.

請參閱第2及3A~3C圖所示,茲說明該封邊結構3的細部特徵及佈設方式如下:在該黏合材料31中,熱熔膠之重量百分比係佔該黏合材料31之10%~65%之間(較佳比例為30%~65%),且熱熔膠與蠟加熱混合後,能透過噴塗方式,由該側邊開口201填充至該間隔空間20中,以黏著在該等面材21、22及中間芯材23之間,將該等面材21、22及中間芯材23黏結成一體。由於該黏合材料31具有較強之黏性,故在該黏合材料31分別附著到該等面材21、22之內側面後,該黏合材料31的中間部位將會因表面張力,形成複數個孔隙310,使該黏合材料31形成一多孔狀之黏合層,如第3B圖所示,根據該黏合材料31的多寡及該熱熔膠的比例,該黏合層可如同蛛網般之平面,或形成宛若棉花糖般之立體結構。 Referring to Figures 2 and 3A to 3C, the detailed features and layout of the edge-sealing structure 3 are as follows: In the adhesive material 31, the weight percentage of the hot-melt adhesive is 10% of the adhesive material 31. Between 65% (preferably 30%~65%), and after the hot melt adhesive is heated and mixed with the wax, it can be filled into the space 20 by the side opening 201 by spraying, so as to adhere thereto. Between the face materials 21 and 22 and the intermediate core member 23, the face materials 21 and 22 and the intermediate core member 23 are bonded together. Since the adhesive material 31 has a strong adhesive property, after the adhesive material 31 is attached to the inner side surfaces of the surface materials 21 and 22, the intermediate portion of the adhesive material 31 will form a plurality of pores due to surface tension. 310, the adhesive material 31 is formed into a porous adhesive layer, as shown in FIG. 3B, according to the ratio of the adhesive material 31 and the ratio of the hot melt adhesive, the adhesive layer can be planar like a spider web or formed. Like a cotton candy-like three-dimensional structure.

該密封材料32亦由熱熔膠及蠟混合而成,其熱熔膠之重量百分比係佔該密封材料32之5%~40%(較佳比例為5%~30%)之間,且該密封材料32中熱熔膠的重量百分比係小於該黏合材料31中熱熔膠的重量百分比,使該密封材料32之黏性小於該黏合材料31之黏性,且較具流動性;該密封材料32亦能透過機台,噴塗至該黏合層(黏合材料31)上,以能至少填滿該黏合層(黏合材料31)上對應該側邊開口201之該等孔隙310(如第3B及3C圖所示),以形成一密封層,令該封邊結構3能水密地密封住該紙板2之側邊開口201。而在本創作之較佳實施例中,該密封材料32能完整覆蓋該黏合層(黏合材料31)上面對該側邊開口201之外側面(如第2圖所示),如同塗佈於該黏合層上之一防水結構。 The sealing material 32 is also made of a hot melt adhesive and a wax, and the weight percentage of the hot melt adhesive is between 5% and 40% (preferably 5% to 30%) of the sealing material 32, and the The weight percentage of the hot melt adhesive in the sealing material 32 is less than the weight percentage of the hot melt adhesive in the adhesive material 31, so that the adhesive material 32 has a viscosity lower than that of the adhesive material 31, and is more fluid; the sealing material 32 can also be sprayed onto the adhesive layer (adhesive material 31) through the machine to fill at least the pores 310 of the adhesive layer (adhesive material 31) corresponding to the side opening 201 (eg, 3B and 3C) The figure is shown to form a sealing layer that allows the edge-sealing structure 3 to hermetically seal the side opening 201 of the paperboard 2. In the preferred embodiment of the present invention, the sealing material 32 can completely cover the outer side of the side opening 201 (as shown in FIG. 2) on the adhesive layer (adhesive material 31), as applied to One of the waterproof structures on the adhesive layer.

如此,由於該黏合材料31之黏性較高,能緊密地黏附在該等 面材21、22之間,使其內含的蠟不至於被吸附至面材21、22中,故能在該間隔空間20中,形成多孔狀之黏合層,以供塗佈該密封材料32,解決傳統瓦楞紙板之側邊開口101內無法塗佈蠟液的問題(如第1圖所示)。此外,更因為該密封材料32的黏性相對較低,能均勻地被覆、滲入至該黏合層,以填滿該等孔隙310,使該黏合層(黏合材料31)、密封材料32能以「一內一外」的方式,形成一完善的水密防護層,防止水氣由該側邊開口201滲入至該等面材21、22或中間芯材23中,從而確保了該紙板2之耐濕性。 Thus, since the adhesive material 31 has high viscosity, it can be closely adhered thereto. Between the face materials 21 and 22, the wax contained therein is not adsorbed into the face materials 21 and 22, so that a porous adhesive layer can be formed in the space 20 for coating the sealing material 32. The problem of not being able to apply wax liquid in the side opening 101 of the conventional corrugated cardboard is solved (as shown in Fig. 1). In addition, because the adhesive material 32 has a relatively low viscosity, it can be uniformly coated and infiltrated into the adhesive layer to fill the pores 310, so that the adhesive layer (adhesive material 31) and the sealing material 32 can be " The inner and outer portions form a perfect watertight protective layer to prevent moisture from penetrating into the surface materials 21, 22 or the intermediate core material 23 from the side opening 201, thereby ensuring the moisture resistance of the paperboard 2 Sex.

透過封邊結構3,除了能提昇該紙板2之耐濕性外,尚能增加其保溫性及耐熱性,此外,該封邊結構3幾乎不會增加該紙板2的重量,因此易於運送,且能輕易摺合成各種款式或規格之紙箱,而其製程亦易於實施,業者僅需在輸送該紙板2的機台上,依序設置二噴嘴,以依序將該黏合材料31及密封材料32噴塗至該側邊開口201中,即可迅速地形成該封邊結構3。 Through the edge-sealing structure 3, in addition to improving the moisture resistance of the paperboard 2, the heat retention and heat resistance can be increased, and further, the edge-sealing structure 3 hardly increases the weight of the paperboard 2, and thus is easy to transport, and It can be easily folded into various styles or specifications of cartons, and the process is easy to implement. The manufacturer only needs to set two nozzles on the machine for conveying the cardboard 2 to sequentially spray the adhesive material 31 and the sealing material 32. The edge seal structure 3 can be quickly formed into the side opening 201.

在此要特別一提者,雖然本創作的主要實施例中,該紙板2係一瓦楞紙板上,即,該中間芯材23之構形係呈波浪彎折狀,但實際上,只要是多層紙材形成的紙板結構、且側邊具有孔隙者,皆可應用該封邊結構3,形成水密保護層。此外,該紙板2在形成該封邊結構3後,可透過人工或機器翻摺,形成紙箱。由於「在紙板上設置不同的凹痕,以翻摺成紙箱」為業界之公知技術,故在此即不另行贅述。 In particular, in the main embodiment of the present invention, the cardboard 2 is formed on a corrugated cardboard, that is, the configuration of the intermediate core 23 is wavy, but in practice, as long as it is multi-layered The paperboard structure formed by the paper material and having the side edges may be applied to the edge sealing structure 3 to form a watertight protective layer. In addition, after forming the edge-sealing structure 3, the paperboard 2 can be folded by hand or machine to form a carton. Since "there are different dents on the paperboard to fold into a carton" is a well-known technique in the industry, it will not be described here.

另,復請參閱第2圖所示,在本創作之較佳實施例中,該紙板2之頂面(即,該第一層面材21之外側面)上尚可塗佈蠟液,以形成一防水層24,且在該紙板2摺合成紙箱後,該防水層24將會位於該紙箱的外側, 以防止紙箱被水漬或水氣所浸濕。 In addition, as shown in FIG. 2, in the preferred embodiment of the present invention, the top surface of the paperboard 2 (ie, the outer side of the first layer material 21) may be coated with a wax liquid to form a waterproof layer 24, and after the cardboard 2 is folded into a carton, the waterproof layer 24 will be located outside the carton. To prevent the carton from being wet by water or moisture.

又,在該紙板2之頂面塗佈蠟液,並固化形成防水層24後,業者尚能在該該第二層面材22之外側面上設置(如:透過液態膠水或熱熔膠黏貼)一緩衝層25,在該瓦楞紙板2被翻摺成紙箱後,該緩衝層25將位於該紙箱之內側(即,面對貨物),且其材質可為發泡材料,如:發泡性聚乙烯(Expandable Polyethylene,又稱EPE、珍珠棉),且能形成一墊體,發泡性聚乙烯具有抗靜電、耐衝撞、防震、不變形、可回收再生等特性,能提昇紙板2(或紙箱)之保溫、絕緣及隔音效果。 Moreover, after the wax liquid is applied to the top surface of the paperboard 2 and solidified to form the waterproof layer 24, the manufacturer can still be disposed on the outer side surface of the second layer material 22 (for example, by liquid glue or hot melt adhesive). a buffer layer 25, after the corrugated cardboard 2 is folded into a carton, the buffer layer 25 will be located inside the carton (ie, facing the goods), and the material thereof may be a foaming material, such as: foaming poly Expandable Polyethylene (also known as EPE, EPE), and can form a cushion body. The foaming polyethylene has antistatic, impact, shockproof, non-deformable, recyclable and other characteristics, and can improve the cardboard 2 (or carton). ) insulation, insulation and sound insulation.

為了提昇該瓦楞紙板2之防撞性,該緩衝層25可由多層發泡材料構成,例如:依據發泡材料的密度,在該第二層面材22上依序黏合高密度、中密度及低密度的發泡材料(珍珠棉),該緩衝層25之厚度可介於2釐米~6釐米,能大幅提昇該瓦楞紙板2的結構強度與承壓力(亦能同時增加保溫性及隔音性),使該瓦楞紙板2形成之紙箱受到外力撞擊時,不易變形、撕裂或破損。 In order to improve the crashworthiness of the corrugated cardboard 2, the buffer layer 25 may be composed of a plurality of layers of foamed material, for example, high density, medium density and low density are sequentially adhered to the second layer 22 according to the density of the foamed material. Foaming material (EPE), the thickness of the buffer layer 25 can be between 2 cm and 6 cm, which can greatly increase the structural strength and bearing pressure of the corrugated cardboard 2 (and also increase the heat preservation and sound insulation). When the carton formed by the corrugated cardboard 2 is impacted by an external force, it is not easily deformed, torn or broken.

此外,復請參閱第2圖所示,該中間芯材23之波浪狀的延伸方向稱為瓦楞紙之「楞向」,該紙板2上平行於其楞向的一側邊設有該側邊開口201,該紙板2上垂直於其楞向之另一側邊則形成有一楞向開口202,該側邊開口201及楞向開口202皆會與該間隔空間20相連通。在本創作之較佳實施例中,因為該側邊開口201之開放性較高,較易受水氣浸濕,故該封邊結構3應優先設於該側邊開口201中,惟,為實現更完整的水密效果,該間隔空間20內鄰近該楞向開口202之部位亦透過相同方式,設置另一封邊結構3。在該瓦楞紙板2的周邊皆被該封邊結構3所密封後,由於該瓦楞紙板2的 內部空氣將無法直接對外流通,故能更進一步提昇其保溫效果,以利於運送海鮮、生鮮食品、酒、花卉等需要保溫運送之貨物。 In addition, as shown in FIG. 2, the wavy extending direction of the intermediate core material 23 is referred to as the "direction" of the corrugated paper, and the side opening of the cardboard 2 is parallel to the side of the slanting direction. 201, a lateral opening 202 is formed on the other side of the cardboard 2 perpendicular to the lateral direction thereof, and the side opening 201 and the opening opening 202 are communicated with the spacing space 20. In the preferred embodiment of the present invention, since the side opening 201 has a high openness and is relatively wetted by moisture, the edge-sealing structure 3 should be preferentially disposed in the side opening 201, however, A more complete watertight effect is achieved, and another edge seal structure 3 is disposed in the same manner in the space adjacent to the opening 202 in the space 20. After the corrugated cardboard 2 is sealed by the edge sealing structure 3, due to the corrugated cardboard 2 The internal air will not be directly circulated outside, so it can further enhance its insulation effect, so as to facilitate the transportation of seafood, fresh food, wine, flowers and other goods that need to be insulated.

承上,根據創作人實際測試,以本創作之技術形成之封邊結構3,其厚度約介於1~5釐米之間(如:黏合材料31之厚度D1及密封材料32之厚度D2分別為1~2釐米),即可形成完善的水密防護層,可見其需使用的熱熔膠及蠟並不多,相對於以往將紙板整個浸泡至蠟液中的作法,本創作能大幅降低所需成本,讓瓦楞紙板製成之紙箱能以較低的成本,達成相同甚至更佳之耐濕性。 According to the actual test of the creator, the edge-sealing structure 3 formed by the technique of the present invention has a thickness of about 1 to 5 cm (for example, the thickness D1 of the adhesive material 31 and the thickness D2 of the sealing material 32 are respectively 1~2 cm), a perfect watertight protective layer can be formed. It can be seen that there are not many hot melt adhesives and waxes to be used. Compared with the previous method of immersing the whole cardboard into the wax liquid, the creation can greatly reduce the required The cost allows the carton made of corrugated cardboard to achieve the same or even better moisture resistance at a lower cost.

本創作之瓦楞紙板2,除了能被翻折成紙箱,以作為貨運裝箱之用途外,尚能應用於建築材料(building material),透過該封邊結構3、防水層24及緩衝層25,該瓦楞紙板2將能具備良好的防水、隔熱、隔音、防撞及承壓效果,且能維持輕量化,能令建築材料的配置更具彈性(如:使建築牆面具保溫及防潮效果)。 The corrugated cardboard 2 of the present invention can be applied to a building material in addition to being folded into a carton for use as a shipping container, through the edge sealing structure 3, the waterproof layer 24 and the buffer layer 25, The corrugated cardboard 2 will have good waterproof, heat insulation, sound insulation, anti-collision and pressure-receiving effects, and can maintain light weight, which can make the configuration of building materials more flexible (such as: making the building wall mask heat preservation and moisture-proof effect) ).
