Description
【発明の詳細な説明】 〔産業上の利用分野〕 この発明は、果実や蔬菜、花卉等の鮮度を良好に保ちな
がら貯蔵や運送等の取り扱いが可能な段ボール製包装箱
に関する。TECHNICAL FIELD The present invention relates to a corrugated cardboard packaging box that can be handled for storage and transportation while maintaining good freshness of fruits, vegetables, flowers, and the like.
青果物の鮮度を保つため、呼吸作用の結果発生するエチ
レンを除去する目的で、エチレン吸着剤を袋に入れて包
装箱内に投入しておくことが良く知られている。It is well known that an ethylene adsorbent is put in a bag and put in a packaging box for the purpose of removing ethylene generated as a result of a respiratory action in order to maintain the freshness of fruits and vegetables.
ところが、このようなエチレン吸着剤入りの袋を青果物
と共に包装箱に投入するのは、手間がかかり、かつ包装
箱内全体に吸着効果を及ぼすためには多数の吸着剤入り
袋を満遍なく投入する必要がある。また、外部からのエ
チレンの浸入を阻止することもできない。However, it is troublesome to put such a bag containing an ethylene adsorbent in a packaging box together with fruits and vegetables, and in order to exert an adsorption effect on the entire packaging box, it is necessary to put a large number of bags containing the adsorbent evenly. There is. Further, it is not possible to prevent the infiltration of ethylene from the outside.
さらに、呼吸作用によって青果物内の炭水化物や他の栄
養成分を分解することになるので、鮮度保持のために
は、この呼吸作用自体を抑制することも大切である。Furthermore, since the respiratory action decomposes carbohydrates and other nutrients in fruits and vegetables, it is important to suppress the respiratory action itself in order to maintain freshness.
そこで、この発明の課題は、エチレン吸着効果に優れ、
同時に呼吸作用も抑制して、青果物の鮮度を極めて有効
に保持することができる包装箱を提供することである。Then, the subject of this invention is excellent in ethylene adsorption effect,
At the same time, it is an object of the present invention to provide a packaging box that can suppress the breathing action and keep the freshness of fruits and vegetables extremely effectively.
上記の課題を解決するため、この発明においては、段ボ
ールに酸素の透過性（ml／m2・１気圧・24時間）が1000
〜35000，炭酸ガスの透過性が1000〜110000の合成樹脂
層を設け、裏ライナの外面に、平方メートル当り1000μ
ｌ以上のエチレンを完全吸着できるエチレン吸着剤塗膜
を設けたウェブによって舗装箱を形成したのである。In order to solve the above-mentioned problems, in the present invention, the corrugated cardboard has an oxygen permeability (ml / m 2 · 1 atmospheric pressure · 24 hours) of 1000.
~ 35,000, carbon dioxide permeability 1000 ~ 110,000 synthetic resin layer is provided, 1000μ per square meter on the outer surface of the back liner
A pavement box was formed by a web provided with an ethylene adsorbent coating film capable of completely adsorbing 1 or more ethylene.
前記合成樹脂層によって酸素と炭酸ガスの透過性を一定
の範囲に制限したので、包装箱に収納した青果物の呼吸
によって、合成樹脂層を介して外気とのガス交換がなさ
れ、一定濃度に達すると包装箱の内外にガスの平衡が生
ずる。呼吸作用を抑制できる好ましい平衡濃度は、酸素
３〜１２％、炭酸ガス３〜１２％であり、前記合成樹脂
の透過性を前記の範囲内で適宜コントロールすることに
よって、平衡濃度を調整すると、呼吸作用が抑制される
ため、代謝機能が低下し、鮮度が保持される。Since the permeability of oxygen and carbon dioxide gas was limited to a certain range by the synthetic resin layer, when the fruits and vegetables stored in the packaging box breathed, gas exchange with the outside air was performed through the synthetic resin layer, and when a certain concentration was reached. Gas equilibrium occurs inside and outside the packaging box. A preferable equilibrium concentration capable of suppressing the respiratory action is oxygen 3 to 12% and carbon dioxide gas 3 to 12%. When the equilibrium concentration is adjusted by appropriately controlling the permeability of the synthetic resin within the above range, respiration Since the action is suppressed, metabolic function is lowered and freshness is maintained.
それに加えて、包装箱内面の少くとも周壁又はほゞ前面
にわたってエチレン吸着剤塗膜が設けられているので、
エチレンが速やかにかつ効率よく吸着され、前記の代謝
機能低下によるエチレンの発生低下とあいまってほゞ完
全にエチレンが除去されるので、鮮度保持効果が相乗的
に高められる。In addition to that, since the ethylene adsorbent coating film is provided on at least the peripheral wall or the front surface of the inner surface of the packaging box,
Ethylene is adsorbed quickly and efficiently, and the ethylene is almost completely removed together with the above-mentioned decrease in the generation of ethylene due to the decrease in metabolic function, so that the freshness-retaining effect is synergistically enhanced.
以下、この発明の実施例を添付図面に基づいて説明す
る。Embodiments of the present invention will be described below with reference to the accompanying drawings.
まず、包装箱を形成するウェブについて説明する。First, the web forming the packaging box will be described.
第１図に示すように、ウエブ１は、段ボール２の表ライ

剤の塗膜６を設けたものである。As shown in FIG. 1, the web 1 comprises a corrugated cardboard 2 having a front liner 3 provided with a synthetic resin layer 4 and a back liner 5 provided with an ethylene adsorbent coating 6 on the outer surface thereof.
前記合成樹脂層４は、表ライナ３の内面に設けてもよく
（図示せず）、或は第２図に示すように、２層の表ライ
ナ３、３′の間に設けてもよく、さらには中芯７や裏ラ
イナ５に設けてもよい。The synthetic resin layer 4 may be provided on the inner surface of the front liner 3 (not shown), or as shown in FIG. 2, between the two-layer front liners 3, 3 '. Further, it may be provided on the center core 7 or the back liner 5.
また、合成樹脂層４に用いる樹脂としては、エチレン−
酢酸ビニル共重合体（ＥＶＡ）、ポリビニルアルコール
（ＰＶＡ）、低密度ポリエチレン（ＬＤＰＥ）、高密度
ポリエチレン（ＨＤＰＥ）、ポリプロピレン（ＰＰ）な
どが用いられる。これらの合成樹脂層４の形成方法は、
フィルムの貼り合せ、コーティング、押し出し等、いず
れでもよい。さらに、適当なフイラー、例えば炭酸カル
シウム、燐酸カルシウム、ケイ酸アルミニウム粉等を添
加したり、金属蒸着層を設けておくことができる。Further, as the resin used for the synthetic resin layer 4, ethylene-
Vinyl acetate copolymer (EVA), polyvinyl alcohol (PVA), low density polyethylene (LDPE), high density polyethylene (HDPE), polypropylene (PP) and the like are used. The method for forming these synthetic resin layers 4 is as follows.
Any of film laminating, coating, extrusion and the like may be used. Further, a suitable filler such as calcium carbonate, calcium phosphate, aluminum silicate powder or the like can be added, or a metal vapor deposition layer can be provided.
上記合成樹脂層４は、ガス透過性をコントロールするも
のであって、単位をml／m2・１気圧・24時間で表したと
き、酸素に対しては1000〜35000、炭酸ガスに対しては1
000〜110000の範囲である。いずれも下限値以下である
と、青果物の呼吸作用による包装箱内のガス濃度の変化
と外気とのガス交換が短時間で行なわれず、酸素の欠乏
及び炭酸ガスの過多が生じ、包装箱内の雰囲気を最適条
件に近づけるのが困難になるため、保存効果をあげるこ
とができない。一方上限値を超えると、ガスの流通が大
き過ぎてガス濃度の平衡を保つことが出来ない。The synthetic resin layer 4 controls the gas permeability, and when the unit is expressed in ml / m 2 · 1 atmospheric pressure · 24 hours, it is 1000 to 35000 for oxygen, and for carbon dioxide gas. 1
It is in the range of 000 to 110,000. If both are lower than the lower limit, changes in gas concentration in the packaging box due to the breathing action of fruits and vegetables and gas exchange with the outside air are not performed in a short time, oxygen deficiency and carbon dioxide excess occur, and Since it becomes difficult to bring the atmosphere close to the optimum conditions, the preservation effect cannot be improved. On the other hand, when the amount exceeds the upper limit, the flow of gas is too large to keep the gas concentration in equilibrium.
次に、前記エチレン吸着剤としては、臭素やパラジウ

チレンの吸着量としては充分であるからである。Next, as the ethylene adsorbent, activated carbon or zeolite impregnated with bromine, palladium, potassium permanganate or the like is used. Further, ordinary activated carbon or the like may be mixed with these. Such ethylene adsorbent as the binder for the coating line, such as styrene butadiene rubber, ethylene - vinyl acetate copolymer is preferably an acrylic resin, the coating amount is 1g / m 2 ~100g / m 2 about is there. In short, the coating should be carried out so that the complete adsorption amount of ethylene is 1000 µl / m 2 or more. Here, the complete adsorption amount refers to the adsorption amount when the equilibrium concentration is zero in the ethylene adsorption isotherm. The reason why the adsorption amount is 1000 μl / m 2 or more is that the storage period in a cardboard box is several days. This is because when it is added, the amount of adsorbed ethylene is sufficient.

できる。According to the present invention, as described above, the liner or the core of the corrugated board is provided with the synthetic resin layer having a certain gas permeability,
Since the packaging box is made of a web that has a coating film that can adsorb ethylene over a certain amount on the back liner, there is no need to put in an ethylene adsorbent, and the atmosphere inside the packaging box changed due to the breathing action of fruits and vegetables. Gas exchange with the outside air is performed through the synthetic resin layer, and it is possible to reduce the breathing action to a gas concentration, which can reduce metabolic function and ethylene production. The amount of the agent used can be reduced, and the combination of the suppression of metabolism and the removal of generated ethylene can prevent aging of fruits and vegetables and maintain good freshness.
