(発明の技術分野)
本発明は無数の微小孔を有する包装用プラスチックフィ
ルムに関する。DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to a packaging plastic film having numerous micropores.
(従来技術とその問題点)
非親水性のプラスチックフィルム、たとえば、ポリエチ
レン系フイルム、塩化ビニリデン系フイルム、塩化ビニ
ル系フイルムは良く知られており、包装用、特に食品包
装用として広く使用されている。これらのフイルムで食
品、特に生鮮食品を包装封閉(以後包装容器と称する)
すると、保存中に短時間で鮮度が悪化する欠点がある。(Prior art and its problems) Non-hydrophilic plastic films, such as polyethylene films, vinylidene chloride films, and vinyl chloride films, are well known and widely used for packaging, especially for food packaging. . These films are used to package and seal foods, especially fresh foods (hereinafter referred to as packaging containers).
This has the disadvantage that freshness deteriorates within a short period of time during storage.
これは包装容器内で生鮮食品が少し変質して、エチレン
ガス、アンモニアガスが発生し、包装容器内に次第に蓄
積し、このガスが変質を更に大きくし、発生ガスは加速
的に増大して包装容器内に充満するため、食品の鮮度が
短時間で著しく悪化するものと思れる。This is because the fresh food deteriorates a little inside the packaging container, generating ethylene gas and ammonia gas, which gradually accumulate inside the packaging container.This gas further increases the deterioration, and the generated gas increases at an accelerated pace. The freshness of the food is likely to deteriorate significantly in a short period of time as the container is filled with water.
(問題点を解決するための手段)
本発明はこの問題を解決するために、食品、特に生鮮食

エチレンガス、アンモニアガス等は包装容器外に排除す

即ち、本発明は非親水性のプラスチックフィルムに無数

小孔に形成された水膜を通して引き続き外部に逸散して
蓄積することがなく、水分は水膜に遮ぎられて包装容器
外に逸散することが殆どなくなる。In the present invention, a conventional non-hydrophilic plastic film is provided with countless micropores, so when food, especially fresh food, is wrapped and sealed with this film, ethylene gas, ammonia gas, moisture, etc. generated from the food are removed from the packaging. It escapes to the outside through numerous micropores in the container. However, since the countless micropores are extremely small, a water film is immediately formed in the micropores. After that, ethylene gas and ammonia gas will continue to escape to the outside through the water film formed in the micropores and will not accumulate, and the water will be blocked by the water film and will not escape outside the packaging container. Almost disappears.
このため、包装容器内の食品の水分は減少することが殆
どなく乾燥することがない。しかも、包装容器内には、
発生したエチレンガス、アンモニアガスが殆ど存在しな
いため、食品特に生鮮食品の保存性は著しく大になる
プラスチックフィルムに6〜14ミクロンの波長の遠赤

る場合は、この遠赤外線が絶えず食品に放射しており、
食品の外部と内部に均一に同時に浸透し、食品内部の水
分を活性化して、食品を殺菌すると共に熟成して美味に
なる。Therefore, the moisture content of the food in the packaging container hardly decreases and the food does not dry out. Moreover, inside the packaging container,
Since there is almost no generated ethylene gas or ammonia gas, the shelf life of food, especially fresh food, is significantly increased.When fine ceramic powder, which easily emits far infrared rays with a wavelength of 6 to 14 microns, is added to the plastic film. This far infrared rays are constantly emitted to food,
It permeates both the outside and the inside of food at the same time, activating the moisture inside the food, sterilizing the food, and ripening it to make it more delicious.
しかも、前記のようにプラスチックフィルムに無数の微
小孔が設けられているため、発生したエチレンガス、ア

ず、保存性は更に著しく大になる。Moreover, as mentioned above, the plastic film has countless micropores, so the generated ethylene gas and ammonia gas escape outside the packaging container, and aging hardly progresses, resulting in significantly longer shelf life. Become.
次に前記セラミックス微粉末の代りにゼオライト微粉末

チックフィルムに無数の微小孔が設けられているため、
相乗効果を表し、前記のように発生したエチレンガス、
アンモニアガスは包装容器外に更に逸散させて排除し、
保存性は更に著しく大になる。Next, when using zeolite fine powder instead of the ceramic fine powder, zeolite fine powder has bactericidal, gas-absorbing, hygroscopic, and ion-exchanging properties, so ethylene is generated from foods during storage. Gas and ammonia gas are adsorbed by zeolite and have a long shelf life. Moreover, because the plastic film has countless micropores,
Representing a synergistic effect, the ethylene gas generated as described above,
Ammonia gas is further dissipated outside the packaging container and eliminated.
Preservability is also significantly increased.
又前記セラミックスとゼオライト微粉末を併用すると、
更に大きな効果が現れる。Also, when the ceramics and zeolite fine powder are used together,
An even greater effect will appear.
非水性のプラスチックフィルムは、ポリオレフィン系、
塩化ビニリデン系、塩化ビニル系のレジンが普通である
が、生産的にも、経済的にも、効果の面からもポリオレ
フィン系、特にポリエチレンが最も好しい。Non-aqueous plastic films are polyolefin-based,
Vinylidene chloride-based and vinyl chloride-based resins are common, but polyolefin-based resins, particularly polyethylene, are most preferred from the viewpoints of production, economy, and effectiveness.
無数の微小孔は小さくなければならない。大きくなると
、微小孔に水膜が形成されにくくなり、水分も発生した
エチレンガス、アンモニアガスと共に包装容器外に逸散
してしまい、本発明の目的を達成することが難しくなる
からである。The countless micropores must be small. This is because if the size of the pores becomes large, it becomes difficult to form a water film in the micropores, and moisture also escapes to the outside of the packaging container together with the generated ethylene gas and ammonia gas, making it difficult to achieve the object of the present invention.
プラスチックフィルムに無数の微小孔を設ける方法は、
本発明の目的を達成することができる方法ならば任意で
あるが、たとえば、無数の微細な針を有するロール又は
板で押すことによって設けるのが普通である。The method of creating countless micropores in a plastic film is as follows.
Although any method can be used as long as the object of the present invention can be achieved, it is usually provided by pressing with a roll or plate having numerous fine needles, for example.
遠赤外線を放射しやすいセラミックス微粉末は天然又は
合成のものが普通であり、多孔質のものはより好しい。Ceramic fine powders that easily emit far-infrared rays are usually natural or synthetic, and porous ones are more preferable.

Products from Shinsei Bio Co., Ltd. and Nippon Serum Co., Ltd. are common.
6ミクロン未満でも、14ミクロンを超える波長のもの
でも本効果が小さくなる。This effect becomes small even if the wavelength is less than 6 microns or exceeds 14 microns.

強い。The fine zeolite powder is suitably natural or synthetic zeolite, Oya stone, or its analogues. A product obtained by adsorbing and ion-exchanging ions of divalent or higher-valent metals, such as Ni, Co, Ag, Ca, Zn, Zr, and Au, has strong sterilizing properties.
セラミックス又は(および)ゼオライト微粉末をプラス
チックフィルムに含有する方法はプラスチック粉末と混
合又は加熱混合して常法により作るのが普通である。The method for incorporating ceramics or (and) zeolite fine powder into a plastic film is usually to mix it with plastic powder or to mix it with heat, using a conventional method.
その量はレジンフイルムに対して、0.5%以上が適当
である。The amount thereof is suitably 0.5% or more based on the resin film.
実施例
ポリエチレンを常法によりポリエチレンフイルムにする

ポリエチレンに合成ゼオライト微粉末3%、8〜12ミ
クロンの波長の遠赤外線を放射しやすいセラミックス微
粉末2%を加えて常法によりポリエチレンフイルムにす

次にこれらを夫々無数の微細針を植えつけたロールに通
過させてフイルムに無数の微小孔を造る。Next, each film is passed through rolls in which countless fine needles are planted, creating countless micropores in the film.
この微小孔は極めて小さく、フイルムの片面に水を加え
たが、水は漏れなかった。The micropores were so small that water did not leak out even when water was added to one side of the film.
次に、生野菜を無数の微小孔を有するAとBのフイルム
で夫々包装封閉した。Next, the raw vegetables were wrapped and sealed with films A and B each having numerous micropores.
比較のため、無数の微小孔を有しないAフイルムで生野
菜を同様に包装封閉した。For comparison, raw vegetables were similarly wrapped and sealed with A film that did not have numerous micropores.
次にこれらを室温で保存した。These were then stored at room temperature.
このテストを5回繰り返した。This test was repeated five times.
この結果、無数の微小孔を有しない従来のAフイルムの
鮮度保持性を1とすると、無数の微小孔を有するAフイ
ルムは、2即ち、2倍と大になり、無数の微小孔を有す

ていた。As a result, if the freshness retention of the conventional A film, which does not have countless micropores, is 1, then the A film, which has countless micropores, is 2 times larger, and the B film, which has countless micropores, is twice as large. The film increased by 3, or 3 times, and was clearly superior.
