본 발명은 숯이 함유된 플라스틱 포장백 및 이의 제조방법에 관한 것으로, 더욱 상세하게는 음식물을 보관하는 포장백에 숯에 의한 항균, 살균, 탈취, 중금속 제거, 원적외선 방출 등과 같은 다양한 기능을 수행하면서 성형이 가능한 숯이 함유된 플라스틱 포장백 및 이의 제조방법에 관한 것이다.The present invention relates to a plastic packaging bag containing a charcoal and a method of manufacturing the same, and more particularly, to perform various functions such as antibacterial, sterilization, deodorization, heavy metal removal, far-infrared emission by charcoal in a packaging bag for storing food. The present invention relates to a plastic packaging bag containing a charcoal and a method for manufacturing the same.

일반적인 숯의 작용으로는 부패균의 발생을 억제하고 오염입자와 냄새를 흡착하며, 원적외선을 방사하고, 음이온이 많이 발생하여 쾌적한 환경을 제공하게 된다. 이는 숯으로부터 발생되는 원적외선과 음이온 그리고 재질과 조직의 특성 등에 의하여 나타나는 효능이다.In general, the action of charcoal suppresses the generation of decayed bacteria, adsorbs pollutants and odors, emits far infrared rays, and generates a lot of negative ions to provide a pleasant environment. This is due to the far-infrared rays and anions generated from charcoal and the properties of materials and tissues.

일반적으로 포장백이란 입구측에 암,수 결합부로 이루어진 지퍼가 구비된 지퍼백 형태 또는 오픈된 위생백 형태의 포장백을 말하는 것으로, 그 내측에 물품을 수납하고 밀봉함으로써 기밀을 유지하여 내용물을 외부환경으로부터 효과적으로 보호할 수 있도록 한 생활용품이며, 특히 신선함과 청결함을 요하는 음식물 등의 보 관이나, 누출되기 쉬운 액상의 물질을 보관하는데 매우 유용한 장점이 있다.In general, the packaging bag refers to a zipper bag or an open sanitary bag with a zipper composed of a male and female coupling part at the inlet side. The bag is kept inside and sealed to keep the contents in an external environment. It is a household goods that can be effectively protected from, and particularly has the advantage that is very useful for storage of liquids, such as storage of food and food that require freshness and cleanliness.

기존에 사용되던 포장백은 일반 플라스틱 수지를 사용하기 때문에 장기간 용액 및 음식물을 보관할 경우 플라스틱 수지에 사용되는 첨가제등이 용출되거나, 플라스틱에서 발생하는 심한 악취도 발생한다. Conventional packaging bags use ordinary plastic resins, so if the solution and food are stored for a long time, additives used in the plastic resins are eluted, or severe odors generated from plastics are generated.

본 발명은 상기한 종래의 문제점을 해소하기 위하여 안출된 것으로, 본 발명의 목적은 음식물을 보관하기 위한 포장백에 숯의 효능인 항균, 살균, 탈취, 중금속제거, 원적외선 방출 등과 같은 다양한 기능을 발휘하면서 플라스틱 포장백의 성형이 가능한 숯이 함유된 플라스틱 포장백 및 이의 제조방법을 제공하는데 있다.The present invention has been made in order to solve the above problems, the object of the present invention is to exhibit a variety of functions such as antibacterial, sterilization, deodorization, heavy metal removal, far-infrared radiation and the like of the efficacy of charcoal packaging bag for storing food While providing a plastic packaging bag containing a charcoal capable of molding the plastic packaging bag and its manufacturing method.

상기한 목적을 달성하기 위하여 본 발명은 숯을 함유한 포장백을 제조함에 있어 합성수지에 입자크기가 300㎛ 이하인 숯 분말을 0.1~15%의 무게비율로 혼합시키고 압출기형 컴파운딩기 내에서 가열·혼련·압출하여 펠렛 형태의 칩으로 만들고, 이 칩을 원료 또는 마스터배치로 하여 압출성형방법으로 제조하거나 압출기에 합성수지와 입자크기가 300㎛ 이하인 숯 분말을 0.1~15%의 무게비율로 직접 투입하고 가열·혼련·압출하여 제조하는 것으로, 포장백에 숯이 갖는 항균, 살균, 탈취, 원적외선 방출, 중금속 제거 등의 기능을 갖으면서 압출 블로우 성형이 가능한 숯 함유 플라스틱을 이용한 포장백의 제조방법을 제공한다.In order to achieve the above object, the present invention is to prepare a charcoal-packed bag containing a charcoal powder having a particle size of 300㎛ or less in a proportion of 0.1 to 15% by weight and heated in an extruder-type compounding machine Kneaded and extruded into chips of pellet form and manufactured by extrusion molding method using these chips as raw materials or masterbatch, or directly putting synthetic resin and charcoal powder having a particle size of 300 μm or less into the extruder at a weight ratio of 0.1 to 15%. The present invention provides a method for manufacturing a bag using charcoal-containing plastic that can be extruded and blow-molded while being heated, kneaded, and extruded, and having functions such as antibacterial, sterilization, deodorization, far infrared emission, and heavy metal removal. .

본 발명에 의한 숯이 함유된 플라스틱 포장백은 기존의 포장백에 천연소재인 숯의 기능을 갖도록 하여 항균, 살균, 탈취 및 원적외선 방출, 중금속 제거 등의 기능을 갖게 한 것으로, 기존의 항균 포장백과는 달리 천연소재를 사용함으로써 인체에 전혀 무해하면서 숯의 효과를 발휘하는 포장백을 기존의 성형기로 제조가 가능하게 하였다.The plastic packaging bag containing the charcoal according to the present invention has the function of charcoal, which is a natural material, in the existing packaging bag, which has functions such as antibacterial, sterilization, deodorization and far infrared emission, and removal of heavy metals. Unlike the use of natural materials, it is possible to manufacture a packaging bag with a conventional molding machine that is harmless to the human body and exerts the effect of charcoal.

본 발명은 숯을 함유한 플라스틱 포장백에 관한 것으로, 더욱 상세하게는 열가소성 합성수지에 적정량의 숯 분말을 함유시켜서 압출 블로우 성형에 의해 포장백을 제조하는 것이다.The present invention relates to a plastic packaging bag containing charcoal, and more particularly, to include a suitable amount of charcoal powder in a thermoplastic synthetic resin to prepare a packaging bag by extrusion blow molding.

숯을 함유한 플라스틱 제품은 범용 수지에 숯이 포함됨으로써 발생하는 수지의 기계적 물성 저하 및 성형성 저하를 최소화시키면서 숯이 가진 기능을 최대한 발휘할 수 있는 것이다.Plastic products containing charcoal can maximize the function of charcoal while minimizing the deterioration of the mechanical properties and moldability of the resin caused by the inclusion of charcoal in the general-purpose resin.

숯은 겉보기 비중이 낮고 내부가 다공성 구조로 되어 있는 친수성 물질이지만 합성수지는 비중이 높고 용융 상태에서 높은 점도를 갖는 소수성 물질이므로 숯과 플라스틱 수지의 혼화성은 그다지 좋지 않다.Charcoal is a hydrophilic material with a low apparent specific gravity and a porous structure inside, but synthetic resin has a high specific gravity and a hydrophobic material having a high viscosity in a molten state, so the compatibility of charcoal and plastic resin is not very good.

따라서 이와 같은 두 물질을 단순히 혼합 시켜주는 방법으로는 숯 분말을 합성수지에 균일하게 분산시켜 줄 수 없게 된다. 즉, 숯 분말이 균일하게 분산되어 있지 않은 합성수지를 원료로 하여 포장백을 성형하게 되면 압출 불로성형시 숯 입자와 고분자 수지사이의 계면에서 찢어짐이 자주 발생하여 성형의 불량이 발생하거나 용융수지의 유동성을 떨어뜨리고 숯 분말이 특정부위에 집중되어 포장백의 품질 저하 및 불량의 원인이 된다.Therefore, it is impossible to uniformly disperse the charcoal powder in the synthetic resin by simply mixing these two materials. In other words, when the packaging bag is molded from synthetic resin that is not evenly dispersed in charcoal powder, tearing occurs frequently at the interface between the char particles and the polymer resin during extrusion blow molding, resulting in poor molding or fluidity of the molten resin. The charcoal powder is concentrated in a specific area, which causes deterioration of quality and defects of the bag.

또한, 숯은 내부에 수많은 기공이 형성되어 있으므로 합성수지와 혼합하여 성형하는 과정에서 온도가 상승됨에 따라 숯 내부의 기공으로부터 공기가 방출되게 되는데, 숯 분말 입자의 크기가 300㎛ 이상의 크기가 되면 공기의 방출량이 크게 되어 성형시 기공이나 핀홀과 같은 불량의 원인이 된다. 따라서 숯을 함유하는 플라스틱 포장백을 제조함에 있어서, 입자크기가 300㎛이하의 미세한 숯 분말을 사용하고 플라스틱과 숯 분말을 내부가 진공상태로 유지된 압출기 형태의 컴파운딩기계를 이용하여 펠렛 형태(pellet type)의 플라스틱 칩(chip)을 만들어 주고, 이 칩을 원료 또는 마스터배치로 하여 포장백을 압출 블로우 성형함으로써 성형과정에서 발생할 수 있는 기공이나 핀홀, 숯 뭉침 현상 등을 제거하여 숯의 기능을 가지면서 품질이 우수한 포장백을 제조할 수 있다.In addition, since the charcoal has a number of pores formed therein, the air is released from the pores inside the char as the temperature is increased during the molding process by mixing with the synthetic resin. The discharge amount is large, which causes defects such as pores and pinholes during molding. Therefore, in the manufacture of plastic packaging bags containing charcoal, pellet form using a fine charcoal powder having a particle size of 300 μm or less and using an extruder-type compounding machine in which the plastic and the charcoal powder are kept in a vacuum state. It is made of pellet type plastic chips, and by extrusion blow molding the bag as a raw material or masterbatch, it removes pores, pinholes and coal agglomeration which may occur during the molding process. It is possible to manufacture a packaging bag having high quality.

또한, 합성수지와 숯 분말을 내부가 진공상태로 유지된 컴파운딩이 가능한 포장백 압출용 압출기에 직접 투입하여 압출기 내에서 가열 혼련과정을 거쳐 압출 성형 방법으로 숯을 함유하는 포장백을 제조하면 제품의 생산성을 향상시킬 수 있다.In addition, the synthetic resin and charcoal powder is directly put into the compounding bag extrusion extruder capable of maintaining the vacuum inside, and the packaging bag containing charcoal is manufactured by the extrusion molding method through a heat kneading process in the extruder. Productivity can be improved.

본 발명에서 제시된 것처럼 입자의 크기가 아주 미세한 숯 분말을 사용하고, 컴파운딩기나 컴파운딩이 가능한 압출기 내부에 진공 상태를 유지시켜 줌으로써 충분한 혼련이 가능하도록 하여 숯과 플라스틱의 물성 차이로 인한 나쁜 혼합성을 극복할 수 있게 된다.As shown in the present invention, the fine particle size of the charcoal powder is used, and by maintaining the vacuum inside the compounding machine or the compounding extruder, sufficient kneading is possible, so that the poor mixing properties due to the difference between the physical properties of the charcoal and plastic To overcome.

이와 같은 방법에 의해 제조된 숯을 함유하는 포장백의 기계적인 물성은 일반 포장백과 큰 차이가 나지 않으며 숯이 갖는 살균 및 항균 작용에 의해 포장백 내부에 세균의 번식을 억제하고, 중금속 흡착작용으로 내용물에 포함된 중금속 및 유해 물질을 제거하며, 숯의 탈취작용에 의해 내용물에서 나는 악취를 제거하는 기능을 갖는다.The mechanical properties of the packaging bags containing charcoal produced by this method do not differ significantly from those of general packaging bags, and they inhibit the propagation of bacteria inside the packaging bags by the sterilization and antibacterial action of the charcoal, and the adsorption of heavy metals. Removes heavy metals and harmful substances contained in, and has the function of removing odor from the contents by the deodorizing action of charcoal.

본 발명은 입구가 지퍼 형태로 구성된 지퍼백, 개방된 위생백, 롤 형태로 이루어진 롤백 등과 같은 포장백의 형태 뿐만 아니라 필름형태의 포장용 랩, 위생장갑 등에도 본 발명을 응용하는 것이 가능하다.The present invention can be applied to the present invention not only in the form of a packaging bag such as a zipper bag, an open sanitary bag, a roll bag made of a roll shape, etc., in the form of a zipper, but also a wrapping wrap, a sanitary glove, etc. in the form of a film.

본 발명은 이하에 기재되는 실시 예에 한정되는 것은 아니고, 본 발명의 사상 및 범주를 벗어나지 않고 다양하게 수정 및 변형할 수 있음은 이 기술의 분야에서 통상의 지식을 가진 자에게 자명하다.The present invention is not limited to the embodiments described below, and it is apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the present invention.

도 1은 본 발명에서 제시된 방법으로 제조된 포장백의 일 예로써, 그에 대한 조직 상태를 부분 확대도로 예시한 것이다.1 is an example of a packaging bag manufactured by the method presented in the present invention, illustrating a tissue state thereof in a partial enlarged view.

본 발명에 따른 플라스틱 포장백(1)은 몸통이 통형으로서 숯 분말(3)을 함유하고 일면이 지퍼(2)로 개방되도록 성형되며, 내부면에 함유된 숯이 포장백 내부의 내용물(4)과 접촉되게 하여 살균, 항균, 탈취 및 중금속 제거효과를 나타내는 것이다.Plastic packaging bag (1) according to the present invention is a cylindrical body containing a charcoal powder (3) and one side is molded to open with a zipper (2), the charcoal contained in the inner contents (4) It is in contact with the bactericidal, antibacterial, deodorant and heavy metal removal effect.

도 2는 본 발명에 따른 숯이 함유된 포장백과 일반 포장백의 살균 성능을 비교한 그래프이다. 일반 포장백과 숯이 함유된 포장백에 일정량의 대장균을 넣어 25℃ 온도에서 하루 동안 유지한 후 대장균 수를 파악하여 일반 포장백과 숯이 함유 된 포장백의 살균 및 항균 성능을 비교하였다. 검사결과, 일반 포장백의 대장균 수를 100%로 할 때 숯이 함유된 포장백의 대장균 수는 28%로 약 72%의 살균 효과가 있음을 알 수 있었다.Figure 2 is a graph comparing the sterilization performance of the charcoal-packing bag and the general packaging bag according to the present invention. After putting a certain amount of Escherichia coli into a normal bag and a bag containing charcoal and maintaining it at a temperature of 25 ° C. for one day, the number of Escherichia coli was determined to compare the sterilization and antibacterial performance of the bag and the bag containing charcoal. As a result of the test, when the number of E. coli in the general packaging bag is 100%, the number of E. coli in the charcoal packaging bag is 28%, which indicates that the bactericidal effect is about 72%.

도 3은 본 발명에 따른 숯이 함유된 포장백과 일반 포장백의 중금속제거 효과를 비교한 그래프이다.Figure 3 is a graph comparing the heavy metal removal effect of the charcoal-packed bag and the normal packaging bag according to the present invention.

숯이 함유된 포장백의 중금속 제거효과를 측정하기 위해 일반 포장백과 숯이 함유된 포장백에 1ppm의 카드뮴 중금속을 넣고 상온에서 7일 동안 보관한 후 1CP-AES(유도플라즈마-원자 발광 분광법)으로 중금속 함유량을 측정하였다.To determine the effect of removing heavy metals from charcoal bags, 1 ppm cadmium heavy metal was placed in normal and charcoal bags and stored at room temperature for 7 days, followed by 1CP-AES (Inductive Plasma-Atomic Emission Spectroscopy). The content was measured.

일반 포장백에서는 약 0.79ppm이 검출되었고 숯이 함유된 포장백에서는 0.14ppm의 중금속이 검출되어 숯이 함유된 포장백은 일반 포장백에 비하여 약 4배의 중금속 제거 효과를 나타내었다.About 0.79ppm was detected in the general packaging bag and 0.14ppm heavy metal was detected in the charcoal bag, and the charcoal bag was about 4 times more effective than the normal bag.

도 4는 본 발명에 따른 숯이 함유된 포장백과 일반 포장백의 경과시간에 따른 탈취 효과를 비교한 그래프이다. 숯이 함유된 포장백과 일반 포장백에 암모니아를 넣고 120분 후, 경과시간에 따른 탈취율을 KICM-FIR-1004방법에 의해 측정하였다. 검사 결과, 일반 포장백의 경우 120분 경과 후 농도가 440ppm 인데 비해 숯이 함유된 포장백의 경우 330ppm으로 약 25%의 탈취율이 증가하였다.Figure 4 is a graph comparing the deodorizing effect of the elapsed time of the charcoal-packed bag and the general packaging bag according to the present invention. 120 minutes after the ammonia was put into the charcoal bag and the normal bag, the deodorization rate according to the elapsed time was measured by the KICM-FIR-1004 method. As a result of the test, the concentration of 440ppm was increased after 120 minutes in the general bag, but the deodorization rate was increased to about 330ppm in the case of charcoal bag.

도 5는 숯이 함유된 포장백에서 숯의 함유량에 따른 살균 능력을 비교한 것 으로 가압밀착법을 이용하여 세균 감소율을 측정하였다. 시험균액을 25℃에서 24시간 정치 배양 후 균주를 측정하였으며, 시료 면적은 60㎠로 하였고 사용 공시균주는 에리시치아 콜리(Escherichia coli) ATCC 25922이었다. 숯의 함유량이 증가함에 따라서 세균 감소율은 증가하였다. 그러나 숯의 함량이 무게비로 15% 이상일 때에는 제품의 성형성이 급격히 저하되어 제품의 품질 저하와 불량 발생률이 높아짐을 고려하면 숯의 함량이 무게비로 0.1～15%인 범위에서 제작하는 것이 적절하다.Figure 5 is a comparison of the sterilization capacity according to the content of the charcoal in the bag containing charcoal was measured by reducing the bacteria using a pressure bonding method. The strain was measured after incubation at 25 ° C. for 24 hours, and the sample area was 60 cm 2, and the used strain was Escherichia coli ATCC 25922. As the char content increased, the bacterial reduction rate increased. However, when the content of charcoal is more than 15% by weight, the moldability of the product is sharply deteriorated, so that the deterioration of product quality and the incidence of defects are high. Therefore, it is appropriate to manufacture the char content in the range of 0.1 to 15% by weight.

도 6은 숯의 함유량에 따른 성형 불량률을 나타낸 것으로, 15% 이상의 함량에서는 불량률이 급격히 높아짐을 알 수 있다.Figure 6 shows the molding failure rate according to the content of the charcoal, it can be seen that the failure rate is rapidly increased at a content of 15% or more.

도 7은 숯 분말의 입자의 크기에 따른 물성치(인장강도)를 나타낸 것으로 300㎛ 이상의 크기에서 급격한 물성 저하를 나타내고 있다. 숯 분말의 크기가 300㎛ 이상의 크기가 되면 숯 분말에서 공기의 방출량이 커져 성형시 기공이나 핀홀과 같은 불량이 발생하여 포장백의 물성이 저하되는 원인이 되므로 300㎛ 이하의 미세한 숯 분말을 사용하여 제작하는 것이 바람직하다.Figure 7 shows the physical properties (tensile strength) according to the size of the particles of the charcoal powder showing a sharp drop in physical properties in the size of 300㎛ or more. When the size of charcoal powder is larger than 300㎛, the discharge of air from charcoal powder increases, which causes defects such as pores and pinholes during molding, which may cause deterioration of the properties of packaging bags. It is desirable to.
