본 발명은 포장용박스를 제조하는데 사용되는 제오라이트층을 갖는 골판지에 관한 것으로, 좀더 상세하게는 과일, 야채, 꽃, 식품 등의 운송 및 보관시에 신선도를 유지할 수 있는 기능을 갖춘 골판지의 제조방법에 관한 것이다.The present invention relates to a cardboard having a zeolite layer used to manufacture a packaging box, and more particularly to a method for producing a cardboard having a function to maintain the freshness during transportation and storage of fruits, vegetables, flowers, foods, etc. It is about.
이와같은 상자의 제조용으로 사용되는 골판지는 제1(a)도에 도시된 바와 같은 구조를 하고 있는 것으로 하대지(1)층 및 상대지(2)층과 전기 하대지(1)층과 상대지(2)층의 사이에서 교호로 접착되어 공간을 형성하는 중간지(3)층으로 구성되어 있으며, 제1(b)도에 도시되어 있는 바와 같은 공정에 의하여 제조되는 것으로 그 제조공정을 살펴보면 다음과 같다.Corrugated cardboard used for the manufacture of such a box has the structure as shown in Fig. 1 (a), and the lower ground (1) layer, the upper ground layer (2) layer, and the electrical lower ground layer (1) layer and the outer ground. (2) is composed of a layer of intermediate paper (3) which is alternately bonded between layers to form a space, and is manufactured by a process as shown in FIG. 1 (b). Same as
원지롤(A)로부터 풀려나오는 중간지(3)을 성형롤(10,10´)의 사이로 통과시켜 주름지의 형태로 변형한 다음 접착제통(11,11´)로 부터 공급되는 접착제(13)이 묻어 있는 접착제도포롤(12,12´)의 사이로 통과시켜 중간지(3)의 상하로 돌출된 표면에 접착제(13)을 도포한 후, 상·하 대지공급롤(B,C)로부터 공급되는 하대지(1) 및 상대지(2)와 함께 압착롤(14,14´)의 사이를 통과시켜 중간지(3)과 하대지(1) 및 상대지(2)를 눌러서 접착시킨 후, 가열건조장치(15,15´)를 통과시켜서 제조된다.The intermediate paper (3) released from the paper roll (A) is passed through the forming rolls (10, 10 ') to be deformed into the form of wrinkled paper, and then the adhesive (13) supplied from the adhesive containers (11, 11') is The
상기와 같은 방법에 의하여 제조되는 골판지를 규정된 전개도의 형상으로 절단 및 조립하여 종래로 부터 사용되는 골판지상자를 제조하였으며, 이와 같은 골판지는 다양한 용도로 이용되었고, 특히 과일, 채소, 건어물 등의 용기로서 많이 이용되어 왔다.By cutting and assembling the corrugated cardboard manufactured by the above method in the shape of the prescribed development view, a corrugated cardboard box used in the related art was manufactured, and such corrugated cardboard was used for various purposes, in particular, containers such as fruits, vegetables, dried fish, etc. It has been used a lot as.
그런데, 과일 및 채소는 생물 그 자체로 보관되고, 생물은 보관되는 기간동안 호흡과 증산작용이 이루어지는 관계로 맑은 공기와 적정량의 수분을 필요로 하게 되나 상기와 같은 종래의 골판지는 종이 자체가 지니는 수분의 흡습성과 배출성에 의하여 약간의 수분조절의 기능을 갖기는 하나, 포장상자 외부의 공기습도 상태에 의하여 그 변화가 심할 뿐만 아니라, 과일등이 호흡을 하는데 필요한 적정량의 맑은 공기를 공급하지 못하여, 심하게 건조되거나, 부패되어버리는 문제가 있었다.By the way, fruits and vegetables are stored in the organism itself, and the living organisms need clean air and an appropriate amount of water due to the respiration and transpiration effect, but the conventional corrugated paper as described above has the moisture of the paper itself. It has a function of controlling moisture due to its hygroscopicity and exhaustability, but it is not only severely changed due to the air humidity condition outside the box, but also can not supply the proper amount of clear air necessary for the fruit to breathe. There was a problem of drying out or decay.
또 건어물등의 경우에 있어서도 상자로 포장하는 단계에서 건어물과 함께 포장이 이루어지는 공기에 부유하는 미생물의 작용에 의하여 적정한 습도로 유지되는 건어물의 경우는 부패를 일으키는 문제가 있으며, 또, 외부공기의 습도변화에 대응하여 내부습도의 민감한 변화를 일으켜 적정의 습도를 유지하기 어려운 문제점이 있었다.Also, in the case of dried fish, dried fish, which are maintained at an appropriate humidity by the action of microorganisms floating in the air that is packaged together with the dried fish in the step of packing in a box, may cause decay, and also the humidity of the outside air. In response to the change caused a sensitive change in the internal humidity there was a problem that it is difficult to maintain the proper humidity.
본 발명은 포장상자 내부의 습도와 외부의 습도를 차단하여 외기에 의한 건조등을 방지함과 동시에 내부공기의 청정을 유지하여 보관되는 과일, 채소, 건어물 등과 같은 식품의 신선도를 유지할 수 있는 제오라이트 층을 갖는 상자용 골판지를 제공함과 동시에 제오라이트 층을 갖는 골판지의 제조방법을 제공하고자 하는 것이다.The present invention is a zeolite layer that can maintain the freshness of the food, such as fruits, vegetables, dried fish, etc. to keep the cleanness of the internal air at the same time to prevent the drying and the like by blocking the humidity inside the packaging box and the outside humidity It is to provide a cardboard for box having a and at the same time to provide a method for producing a cardboard having a zeolite layer.

제2(b)도는 본 발명의 골판지를 제조하는데 적용되는 제조공정도.Figure 2 (b) is a manufacturing process chart applied to manufacture the cardboard of the present invention.
상기와 같은 문제점을 해결하기 위한 본 발명의 제오라이트층을 갖는 골판지는 제2(a)도에 도시되어 있는 바와 같이 골판지의 외면을 형성하는 하대지(1)층 및 상대지(2)층과 전기 하대지(1)층과 상대지(2)층의 사이에서 교호로 접착되어 공간을 형성하는 중간지(3)층, 중간지(3)층과 상대지(2)층의 사이의 공간에 충진되어 있는 제오라이트(4)층로 구성된다.Corrugated paper having a zeolite layer of the present invention for solving the above problems as shown in Figure 2 (a) and the bottom plate (1) layer and the counterpart (2) layer forming the outer surface of the corrugated cardboard and electrical Filled in the space between the intermediate paper (3) layer and the intermediate paper (3) layer and the counterpart (2) layer, which are alternately bonded between the lower ground (1) layer and the counterpart (2) layer to form a space. It consists of a
또, 하대지(1)층과 상대지(2)층의 사이에 중간지(3)층이 이중으로 형성되고 각 중간지(3)층의 상부에 제오라이트(4)의 층을 갖도록 구성될 수 있다.In addition, the intermediate paper (3) layer may be formed in duplicate between the lower base (1) layer and the counterpart (2) layer, and may be configured to have a layer of zeolite (4) on top of each intermediate paper (3) layer. have.
제오라이트는 일반적으로 알루민산나트륨과 규산나트륨의 반응에 의하여 생성되는 화합물로서 자연계에서는 나트륨의 일부가 칼슘등에 의하여 치환된 형태로 존재하기도 하며, 그 자체가 지니는 미세한 기공에 의하여 흡착 및 정제하는 작용을 하여 분자체로서 사용되기도 하고, 화합물에 존재하는 양이온에 의한 치환능력으로 인하여 가스등을 흡착하는 성질등의 다양한 성질을 지니고 있어, 토양개량제, 수분제거제, 수처리제 및 각종의 첨가제로서 다양한 용도로 사용되는 화합물이다.Zeolite is generally a compound produced by the reaction of sodium aluminate and sodium silicate. In nature, some of sodium exists in the form of substitution by calcium, etc., and it adsorbs and purifies by its own fine pores. It is used as a molecular sieve and has various properties such as adsorption of gas due to the substitution ability by cations present in the compound, and is used for various purposes as soil improving agent, water removing agent, water treatment agent and various additives. .
본 발명에서는 제오라이트가 갖는 성질중의 하나인 수분의 흡수와 배출능력을 이용하여 과일, 채소등의 보관시에 일어나는 증산작용에 의하여 발생하는 수분의 흡착 및 정제된 수분을 적정하게 공급함과 아울러 생물의 호흡작용에 의하여 발생되는 가스로 부터 탄산가스등을 흡착하여 맑은 공기를 계속하여 공급할 수 있는 기능을 이용한 것이다.In the present invention, by using the ability to absorb and discharge moisture, which is one of the properties of zeolites, it is possible to adequately supply the adsorption and purified water of moisture generated by the transpiration effect that occurs during storage of fruits and vegetables. By using carbon dioxide gas from the gas generated by the respiratory action to continue to supply clean air.
따라서 본 발명에서 사용되는 제오라이트는 비교적 많은 기공을 갖는 입자일수록 유리하며, 그 입도에 있어서는 주름지와의 부착성등을 고려하면 대략 평균직경이 0.1mm~0.5mm 정도의 것이 적당하다.Therefore, the zeolite used in the present invention is advantageous as the particle having a relatively large number of pores, and in the particle size, it is appropriate that the average diameter is about 0.1 mm to 0.5 mm in consideration of adhesion to wrinkle paper.
상기와 같은 구성을 갖는 본 발명의 골판지는 다양한 방법에 의하여 제조될 수 있는 것으로 예를들면, 접착제와 제오라이트를 미리 혼합하여 두고 중간지(3)와 상대지(2)의 접착 직전에 중간지(3)의 골 부분에 채워 넣는 방법이 있을 수 있으나, 이 경우는 건조후 제오라이트의 표면에 과도한 접착제의 막이 형성되어 제오라이트의 기공을 막아주는 결과를 초래하므로 원활한 수분의 공급 및 흡착성능이 다소 떨어지게되는 결점을 지니게 된다.Corrugated cardboard of the present invention having the configuration as described above can be produced by a variety of methods, for example, the adhesive and zeolite is mixed in advance, the intermediate paper (3) and the intermediate paper just before the adhesion (2) There may be a method of filling in the bone part of 3), but in this case, since the excessive adhesive film is formed on the surface of the zeolite after drying, the pore of the zeolite is prevented, so that the smooth supply and adsorption performance of the water is slightly decreased. You have a drawback.
본 발명의 제조방법은 접착제가 제오라이트의 표면에 극히 부분적으로 처리되어 충분한 기공을 확보할 수 있도록 한 것으로 본 발명의 제오라이트층을 갖는 골판지는 그 일실시예로서 제2(b)도에 도시되어 있는 바와 같은 공정에 의하여 제조되므로 제2(b)도에 도시되어 있는 공정에 의하여 설명하기로 한다.According to the manufacturing method of the present invention, the adhesive is extremely partially treated on the surface of the zeolite to secure sufficient pores. The corrugated paper having the zeolite layer of the present invention is shown in FIG. Since it is manufactured by the process as described above will be described by the process shown in Figure 2 (b).
원자롤(A)로 부터 풀려나오는 중간지(3)을 성형롤(10,10´)의 사이로 통과시켜 주름지의 형태로 변형한 다음 접착제통(11,11´)로 부터 공급되는 접착제(13)이 묻어 있는 접착제도포롤(12,12´)의 사이로 통과시키되 상부의 접착제도포롤(12)를 중간지의 진행방향에 대항되게 회전시켜 접착제(13)이 중간지(3)의 하부 돌출면과 상부돌출면에 도포되면서, 상부면은 형성된 골을 향하여 흘러들어가도록 한 다음, 제오라이트(4)를 제오라이트 공급노즐(16)을 통하여 공기공급라인(18)을 통하여 들어오는 가압공기와 함께 분사시켜, 상부돌출면 및 골에 도포되어 있는 접착제에 의하여 부착이 되게 하고 이어서 스크레이퍼(17)을 통과하면서 상부돌출면에 부착되어 있는 제오라이트를 뒤따라 들어오는 골에 밀어넣고 상·하 대지공급롤(B,C)로부터 공급되는 하대지(1) 및 상대지(2)와 함께 압착롤(14,14´)의 사이를 통과시켜 중간지(3)과 하대지(1) 및 상대지(2)를 눌러서 접착시킨 후, 가열건조장치(15,15´)를 통과시켜서 제조된다.The intermediate paper (3) released from the atomic roll (A) is passed through the forming rolls (10, 10 ') to be deformed into the form of wrinkled paper, and then the adhesive (13) supplied from the adhesive containers (11, 11'). The
