Abstract
Description
본 발명은 과일 포장재의 제조방법에 관한 것으로, 특히 과일을 개별 포장하기 위한 펄프를 주재로 하는 포장재에 관한 것이다.The present invention relates to a method for producing a fruit packaging material, and more particularly to a packaging material mainly containing pulp for individually packaging the fruit.
종래, 개별적으로 포장하는 포장재로는 주로 발포 폴리에틸렌이나 발포 폴리스티렌 재료가 사용되고 있으며, 그 형태는 도 1에 도시된 형태로 구성되어 있다. 개별형 과일 포장재는 본체(1)와, 포장 본체(1) 하단 외주연으로는 연속 연결되는 형태로 다수개의 밀착편(12)이 형성되어 있다.Conventionally, foamed polyethylene or foamed polystyrene materials are mainly used as packaging materials to be individually packaged, and their forms are configured in the form shown in FIG. The individual fruit packaging material is formed of a plurality of close contact pieces 12 in a form that is connected to the main body 1 and the outer periphery of the lower end of the packaging body 1 continuously.
이때, 상기 포장커버 본체(1)는 도 1 및 도 2의 A-A선 단면도로 도시된 바와 같이 대략 밀짚모자 형상을 취하는 것으로, 본체(1) 중앙은 반구 형태의 융기부로서, 밀착면(13)으로서 과일 포장시 과일을 본체(1) 내부로 수용시키며 과일 외부면에 밀착하여 과일을 포장,보호하는 기능을 하게되는 것이다.At this time, the packaging cover body (1) has a straw hat shape as shown in the cross-sectional view AA line of Figures 1 and 2, the center of the body (1) is a hemispherical ridge, the contact surface 13 As a fruit packaging when the fruit is accommodated in the main body (1) and close to the outer surface of the fruit to function to package, protect the fruit.
또한, 상기 다수개로 구성된 밀착편(12)은 대략 만개(滿開)한 코스모스 꽃잎 형상을 취하는 것으로, 이와 같은 밀착편(12)은 전술한 밀착면(13)과 동일한 기능으로서 과일을 본체(1) 내부로 수용하며 포장하는 기능을 함과 동시에 과일이 포장되어질 때 대략 꽃이 피어나기 직전의 꽃 봉오리 형상으로 수축(收縮)되며 과일이 포장커버 본체(1)내에 포장된 후 포장커버(1)와 쉽게 분리되지 않도록 과일 외부면을 조여주며 밀착된다.In addition, the contact piece 12 composed of a plurality of pieces has a cosmos petal shape of approximately full bloom, and the contact piece 12 has the same function as that of the contact face 13 described above. ) At the same time, when the fruit is packaged, it shrinks into a bud shape just before the flower blooms, and after the fruit is packed in the packing cover body (1), the packing cover (1) and Tighten the outer surface of the fruit so it does not separate easily.
즉, 도 3에 도시한 바와 같이, 과일이 본체(1)중앙에 올려지게 되면 밀착면(13)은 과일 자체하중에 의해 눌려지게 되어 본체(1)가 밀짚모자 또는 만개한 코스모스 형상에서 피어나기전의 꽃 봉오리형상으로 뒤집혀 수축하게 된다.That is, as shown in Fig. 3, when the fruit is placed in the center of the main body 1, the contact surface 13 is pressed by the fruit self-load so that the main body 1 before the main body 1 blooms in a straw hat or cosmos shape in full bloom. It is turned into a bud and contracted.
그러나, 이러한 종래의 포장재는 합성수지로 제작되어 있어 과일에서 발산되는 가스(에틸렌가스)를 흡착하지 못하고, 공기가 통하지 않아 과일이 밀착되는 하단부에서 발산가스에 의해 과일이 부패되고 짓무르는 등 형태의 변화나, 당도의 변화 등이 있어 과일을 장기간 보관하는 데는 문제점이 많았다.However, such a conventional packaging material is made of synthetic resin, so that the fruit does not adsorb gas (ethylene gas) emitted from the fruit, and the fruit is decayed and crushed by the emanating gas at the lower end where the fruit is in close contact with the air. There have been many problems in storing fruits for a long time due to changes and changes in sugar content.
따라서, 본 발명의 목적은 장기간 과일을 신선하게 보관할 수 있는 과일 포장재의 제조방법을 제공하는 것이다.Accordingly, it is an object of the present invention to provide a method for producing a fruit packaging material which can keep fresh fruit for a long time.
도 1은 종래 과일 트래이의 사시도1 is a perspective view of a conventional fruit tray
도 2는 종래 과일 트래이의 단면도2 is a cross-sectional view of a conventional fruit tray
도 3은 종래 과일 트래이의 사용상태도3 is a state diagram used in the conventional fruit tray
상기 본 발명의 목적은 폐지를 펄핑탱크에서 펄프화작업을 하고, 교반기를 사용하여 기계적처리를 하는 고해작업을 한 다음, 은, 산화티탄 및 제올라이트로 구성되는 그룹으로부터 선택된 하나 이상의 첨가제를 부가한 다음 진공성형기에서 1차 성형하여 형태를 완성한 다음, 핫 프레스(Hot Press)에서 200-250℃로 3차에 걸쳐 수분제거 및 살균을 하는 것으로 구성되는 과일 포장재의 제조방법에 의해서 달성된다.The object of the present invention is to pulp the waste paper in the pulping tank, perform the beating work by mechanical treatment using a stirrer, and then add one or more additives selected from the group consisting of silver, titanium oxide and zeolite It is achieved by a method of manufacturing a fruit packaging material, which is primarily formed in a vacuum molding machine to complete the form, followed by three times of water removal and sterilization at 200-250 ° C. in a hot press.
본 발명의 공정에 첨가되는 은, 산화티탄, 제올라이트 등은 항균력이 있어 과일이 병균에 감염되는 것을 방지해 주고, 공기를 청정하게 하는 효과가 있어 과일의 선도 유지에 도움이 된다. 이러한 첨가제는 주원료가 되는 폐지 무게의 0.5-7%의 양으로 첨가되는 것이 바람직하다. 그 이하의 양으로 첨가되는 항균효과가 제대로 나타나지 않으며, 그 이상의 양으로 첨가되는 경우 비용이 증가하고, 트래이의 무게가 너무 무거워지는 경향이 있다.Silver, titanium oxide, zeolite and the like added to the process of the present invention have an antimicrobial effect to prevent the fruit from infecting germs and to clean the air to help maintain the freshness of the fruit. Such additives are preferably added in an amount of 0.5-7% of the weight of the waste paper used as the main raw material. Antimicrobial effects added in amounts below that do not appear properly, and when added in amounts higher than that, the cost increases and the weight of the tray tends to be too heavy.
이하 본 발명을 실시예를 통해 더욱 상세하게 설명한다.Hereinafter, the present invention will be described in more detail with reference to Examples.
