본 발명은 과실, 야채등의 청과물의 포장에 사용하는 필름에 관한 것으로서, 특히 에틸렌 기체를 유착하여 청과물의 선도유지에 우수한 효과를 갖는 포장용 필름에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film used for packaging fruits and vegetables such as fruits and vegetables, and more particularly relates to a packaging film having an excellent effect on adhering ethylene gas to freshness of fruits and vegetables.
종래에는 과실이나 야채등의 청과물을 저장하는 경우 그 보존성능이 청과물 자체가 발생하는 에틸렌 가스의 생성량에 관계하여 저장고내의 에틸렌 기체를 제거함으로써 청과물의 선도유지가 가능한 시간을 비약적으로 연장시킬 수 있다는 것으로 알려져있다.Conventionally, when storing fruits and vegetables such as fruits and vegetables, the preservation performance of the fruits and vegetables itself can be significantly increased by removing the ethylene gas in the storage room in relation to the amount of ethylene gas generated. Known.
청과물은 그자체 에틸렌을 생성하여 성숙하는 것으로 밀폐된 저장고내에서는 청과물 자체가 생성하는 에틸렌의 농도가 높아져 그 결과 성숙이 촉진되어 청과물의 선도가 급격히 저하한다.Fruits and vegetables themselves produce and mature ethylene. In an enclosed cellar, the concentration of ethylene produced by the fruits and vegetables itself increases, resulting in accelerated maturation, leading to a sharp decline in freshness.
따라서 청과물의 선도를 유지 하기위해서는 청과물로부터의 에틸렌의 발생을 억제하고, 발생한 에틸렌을 제거하는 것이 중요한 문제가 된다.Therefore, in order to maintain the freshness of fruits and vegetables, it is important to suppress the generation of ethylene from the fruits and vegetables and to remove the generated ethylene.
에틸렌기체를 제거하여 청과물의 선도유지를 이루기 위하여 청과물 보조용 선도유지재로서는 수 옹그스트롱의 세공을 갖는 탄소에 취소를 흡착시킨것이 예를 들면 일본 특허공고 55-5045호 공보등에 알려져 있다.It is known, for example, in Japanese Patent Publication No. 55-5045, etc., to remove ethylene gas and to adsorb fresh fruit to carbon having water pores of water-long-strength as a fresh oil retaining material for auxiliary fruits and vegetables.
그러나 상기 공보에 나타나 있는 것같은 선도유지재는 저장고내에 설치하여 저장고내 전체의 에틸렌을 제거하고자 하는 것이어서 대량의 선도유지재를 필요로 하고 더욱이 완전히 에틸렌을 제거하기는 곤란하다.However, the lead holding material as shown in the above publication is to be installed in the storage to remove the entire ethylene in the storage, so it requires a large amount of leading holding material and it is more difficult to completely remove the ethylene.
특히 각각의 청과물의 표면에는 가성 고농도의 에틸렌이 잔존체류하고 있어 이것을 완전히 제거하기란 매우 어렵다.In particular, caustic high concentration of ethylene remains on the surface of each fruit and vegetable, and it is very difficult to completely remove it.
따라서 장시간에 걸쳐서 청과물의 선도를 유지하는 것은 매우 곤란하였다.Therefore, it was very difficult to maintain the freshness of fruits and vegetables for a long time.
또 소량의 청과물을 보존 하는 경우에라도 그때그때 선도유지재를 저장고내에 넣어야만 하고 일손이 많이 필요하며 번잡하여서 저장코스트가 높아지게 된다는 문제가 있었다.In addition, even in the case of preserving a small amount of fruits and vegetables, there was a problem that the lead holding material must be put in the storage at that time, the labor cost is high, and the storage cost is high.
본 발명자등은 상기한 목적을 달성하기 위하여 예의 검토한 결과 에틸렌 흡착능을 갖는 필름으로 포장하는 것을 고안하여 본 발명에 도달하였다.MEANS TO SOLVE THE PROBLEM As a result of earnestly examining in order to achieve the said objective, the present inventors devised to package it into the film which has ethylene adsorption capacity, and reached | attained this invention.
즉, 본 발명은 에틸렌 흡착능을 갖는 것을 특징으로 하는 선도유지용 필름이다.That is, the present invention is a film for freshness holding having an ethylene adsorption capacity.
여기서 에틸렌 흡착능이란 에틸렌을 흡착하는 성질로서 1시간, 1m2마다 0.005ppm이상의 에틸렌을 흡착하는 능력을 갖는 것이 바람직하다.Here, the ethylene adsorption capacity is a property of adsorbing ethylene, and preferably has an ability to adsorb 0.005 ppm or more of ethylene every 1 m 2 for 1 hour.
이러한 에틸렌흡착능을 갖는 필름은 세다공질 재료를 필름에 첨가하는 것에 의하여 얻을 수 있다.Such a film having ethylene adsorption capacity can be obtained by adding a microporous material to the film.
세다공질재료라 함은 2-2800옹그스트롱의 세공을 갖는 다수개 갖는 무기재료이며, 오오야석, 제오라이트, 활성탄, 크리스트버라이트, 크리노푸티로라이트등을 예시할 수가 있다.The microporous material is an inorganic material having a plurality of pores of 2-2800 angstroms, and examples thereof include an oya stone, zeolite, activated carbon, cristerite, and cryoputirolite.
다시 이러한 세다공절재료를 분쇄하고 미량의 금속 산화물을 첨가하여 혼련소결한 것이라도 좋다. 세다공질재료를 필름에 첨가하는데는 세다공질재료를 분쇄하여 미분말로 해서 통상의 방법에 필름용 폴리머중에 첨가혼합하여 막으로 만들면 좋다. 이 세다공질재료 미분말의 입도는 200메쉬 이상이 좋고, 또 필름중에 함유량은 1중량% 이상이 바람직하다.The fine porous material may be pulverized again and kneaded and sintered by adding a small amount of metal oxide. In order to add the microporous material to the film, the microporous material may be pulverized into fine powder, and then mixed with the usual method in the polymer for film to form a film. The fine particle size of the fine porous material is preferably 200 mesh or more, and the content of the fine porous material is preferably 1% by weight or more.
더욱이, 세다공질재료에 전자파 또는 오존을 작용시켜 산소처리를 행하여 놓으면 에틸렌 흡착능이 향상하여 적당하다.Furthermore, when oxygen treatment is performed by applying electromagnetic waves or ozone to the microporous material, the adsorption capacity of ethylene is improved, which is suitable.
본원 발명에서 무기질 세다공재료에 대한 산소처리는 산화제인 오존을 이용하여 산소처리하는 방법으로서 산화촉매로 하여 오존을 충진한 다음 파이프를 통해 오존을 10cc/sec의 유량으로 통과시키면 세다공재료가 산소처리된다.Oxygen treatment for the inorganic porous material in the present invention is a method of oxygen treatment using ozone which is an oxidizing agent. After filling the ozone with an oxidation catalyst and passing the ozone at a flow rate of 10 cc / sec through a pipe, the microporous material becomes oxygen Is processed.
또 전자파 처리는 파이프속을 통하여 전자파가 나오도록 구성된 장치를 이용하며 이때 전자파의 처리는 세다공재료에 1849-2537A
또한, 세다공질재료를 첨가하는 필름은 에틸렌 흡착능을 지닐뿐만아니라 산소, 탄소 기체, 질소, 에틸렌, 수증기등의 기체투과성에도 우수하며, 에틸렌기체를 포장필름 밖으로 배출하여 포장 필름의 내측을 적당한 습도로 유지할 수가 있기 때문에 청과물의 선도를 유지하는 효과가 한층 향상한다.In addition, the film containing the microporous material not only has the ability to adsorb ethylene, but also has excellent gas permeability such as oxygen, carbon gas, nitrogen, ethylene, water vapor, etc. Since it can hold | maintain, the effect of maintaining the freshness of a fruit or vegetable further improves.
본 발명의 선도유지용 필름소재에는 통상 포장용에 사용되고 있는 폴리에틸렌, 폴리프로필렌, 폴리부타디엔, 포리초산비닐, 폴리에스테르, 폴리아미드등을 사용할 수 있으나 폴리염화비닐, 폴리염화비닐리텐과 같이 염소원자를 포함하는 또는 가소제를 포함하는 것이 충분한 에틸렌흡착능의 발휘할 수 없게 될 염려가 있어서 피하는 것이 좋을 것이다.In the lead-retaining film material of the present invention, polyethylene, polypropylene, polybutadiene, vinyl polyacetate, polyester, polyamide, and the like, which are usually used for packaging, may be used, but include chlorine atoms such as polyvinyl chloride and polyvinylidene chloride. Or including a plasticizer may be prevented from exhibiting sufficient ethylene adsorption capacity.
이하 실시예에 의해 본 발명을 다시 상세하게 설명한다.Hereinafter, the present invention will be described in detail with reference to the following Examples.
[실시예 1]Example 1
오오야석에 오존을 100cc/sec의 유량으로 작용시켜 산소처리를 행하고 여기서 얻어진 산소처리된 오오야석을 200메쉬 이상의 입도로 분쇄하여 폴리에틸렌중에 5중량%첨가혼합하여 두께 40μ의 필름으로 만들었다.Oxygen treatment was performed by applying ozone to a flow rate of 100 cc / sec, and the oxygenated Oya stone thus obtained was pulverized to a particle size of 200 mesh or more, mixed with 5% by weight in polyethylene to give a film having a thickness of 40 µ.
한편, 수확직후의 시름치(품종, 1대잡종 다레드)중 건전한 5주를 3조 선정해서 어느것이나 수지제 원통형 용기에 수직으로 세우고, 그중 1조를 상기한 FILM으로 밀봉포장하여 저장고내에 15
또, 비교를 위해 나머지 2조의 한편을 시판하는 폴리에틸렌 필름으로 밀봉포장하여 다른것을 무포장한 그대로 15
각 견본에 대해서 저장개시 적후로부터 3일간에 걸쳐 시금치 표면에 존재하는 에틸렌 농도를 측정하였다.For each specimen, the concentration of ethylene on the spinach surface was measured over three days from the start of storage.
그 결과는 제 1 도에 나타나는 것과 같다.The result is as shown in FIG.
제 1 도는 결과에도 명확하듯이 본 발명의 필름을 사용한 경우(곡선A)에는 생성 에틸렌이 필름에 흡착되어 시금치 표면에 잔존한 에틸렌양이 적어졌지만 폴리에틸렌필름을 사용한 경우(곡선 B)및 무포장의 경우 (곡선C)에는 시금치 표면에 잔존한 에틸렌양이 많았다.As shown in FIG. 1, the results of the film of the present invention (curve A) resulted in adsorption of ethylene on the film and the amount of ethylene remaining on the spinach surface was reduced. In the case (curve C), the amount of ethylene remaining on the spinach surface was large.
저장개시 3일후의 각 시금치 샘플의 상태를 관찰하니까 클로로필 분해에 의해 황색으로 변색한 잎의 수가 본 발명의 필름을 사용한 것에는 단지 2매이었던것에 비하면, 폴리에틸렌필름을 사용한것에서는 7매, 무포장인 것에서는 4매이었다.Observing the state of each spinach sample three days after the start of storage, the number of leaves which turned yellow by chlorophyll decomposition was only 2 sheets using the film of the present invention, compared to 7 sheets using the polyethylene film and no packing. It was four in thing.
또, 본 발명의 필름을 사용한 것에서는 시금치를 포장한 필림의 내측이 적당한 습도로 보존되었지만, 폴리에틸렌필름을 사용한 것은 포장필름의 내측이 물러지게 되고 무포장인 것에서는 시금치가 약간 변하였다.In addition, in the case of using the film of the present invention, the inside of the film packaged with the spinach was preserved at an appropriate humidity, but in the case of using the polyethylene film, the inside of the packaging film was receded and the spinach was slightly changed in the unpacked case.
[실시예 2]Example 2
크리스트버라이트분말에 소량의 석여과 TiO2, Al2O3, Fe2O3, CaO, Na2O를 첨가하여 혼련하여 점토를 만들고, 이것을 조립시켜 100℃전후의 온도로 예비건조시킨 후 700℃에서 소결한 것에 1849-2537옹그스트롱(A°)의 영역내의 전자파를 조사하여 산소처리를 하였다.A small amount of filtration, such as TiO 2 , Al 2 O 3 , Fe 2 O 3 , CaO, Na 2 O, is kneaded to make a clay, and then granulated and pre-dried at a temperature of around 100 ° C. Oxygen treatment was carried out by irradiation with electromagnetic waves in the region of 1849-2537 Angstrom (A °).
이어서 이 처리물을 200메쉬 이상의 입도로 분쇄하여 폴리에틸렌중에 5중량%첨가혼합하여 두께 40μ의 필름으로 만들었다.Subsequently, the treated material was ground to a particle size of 200 mesh or more, and mixed with 5% by weight in polyethylene to give a film having a thickness of 40 mu.
다시 산소처리에 의해 얻어진 것의 화학조성(%)은 하기와 같았다.The chemical composition (%) of what was obtained by oxygen treatment again was as follows.

실시예 4에 사용한 산소처리 제오라이트를 폴리프로필렌중에 7중량%첨가혼합하여 두께 40μ의 필름으로 만들었다.Oxygenated zeolite used in Example 4 was mixed with 7% by weight in polypropylene to give a film having a thickness of 40 mu.
한편 수확직후의 브로커리(품종, 녹색)중에서 비교적 생체중이 정돈된 건전한 것 6개를 전 생체중이 될수 있을만큼 정돈하여 3조로 나누어 그중의 1조를 상기 본 발명의 필름으로 밀봉포장하여 저장고내에 15°-25℃로 저장하였다.On the other hand, six healthy things of relatively fresh weight in brokerages (variety, green) immediately after harvesting are arranged to be full weight, divided into three sets, and one set of them is sealed with the film of the present invention and placed in a reservoir at 15 °. Store at -25 ° C.
또 비교를 위하여 나머지 2조의 한편을 시판의 포장용 폴리프로필렌 필름으로 포장하고 다른 것은 무포장의 상태로 저장고내에 15°-25℃로 저장하였다.For comparison, one of the remaining two sets was packed with a commercially available packaging polypropylene film and the other was stored at 15 ° -25 ° C. in the store without packaging.
각 샘플에 대하여 저장개시 직후로 부터 5일간에 걸쳐 브로커리 표면에 존재하는 에틸렌 농도를 측정하였다.For each sample, the concentration of ethylene on the surface of the brokerage was measured over five days immediately after the start of storage.
그 결과는 제 5 도에 나타나는 것과 같았다.The result was as shown in FIG.
제 5 도의 결과에서도 확실한 것같이 본 발명의 필름을 사용한 경우(곡선 A)에는 생성에틸렌이 필름에 흡착되어 브로커리의 표면에 잔존하는 에틸렌양이 매우 적게 되었으나 폴리프로필렌 필름을 사용한 경우(곡선 B) 및 무포장의 경우(곡선 C)에는 브로커리 표면에 잔존한 에틸렌양이 많았다.As is clear from the results of FIG. 5, when the film of the present invention was used (curve A), the produced ethylene was adsorbed onto the film, and the amount of ethylene remaining on the surface of the brokerage was very small, but a polypropylene film was used (curve B) and In the case of no packaging (curve C), there was a large amount of ethylene remaining on the surface of the brokerage.
저장개시 5일후의 각 샘플의 상태를 관찰하였더니 본 발명의 필름을 사용한것에서도 거의 변색되지 않았고, 속도 거의 부풀지 않았지만 폴리프로필렌필름을 사용한 것에서는 갈색의 변색이 나타나기 시작해 속도 크게 되고 무포장의 것에서는 브로커리가 황화하여 속도 크게 되었다. 또, 본 발명의 필름을 사용한 것에서는 브로커리의 포장 내측이 적당한 습도로 유지되었지만 폴리프로필렌필름을 사용한 것에서는 포장필름 내측이 뭉그러져서 무포장의 것에서는 브로커리가 약간 상해져 있었다.The state of each sample was observed 5 days after the start of storage. When the film of the present invention was used, the color of the sample was almost discolored, and the rate of change was almost indistinct. In this case, the brokerage was sulfided and the speed increased. In addition, in the case of using the film of the present invention, the inside of the packaging was kept at an appropriate humidity, but in the case of using the polypropylene film, the inside of the packaging film was crushed, and in the unpacked, the brokerage was slightly damaged.
