Description

냉각수단을 갖는 페트병의 열 수축성 필름 피복방법 및 그에 따른 냉각수단Method for coating heat shrinkable film of PET bottle with cooling means and cooling means accordingly
본 발명은 주로 페트병의 외면에 제품의 출처표시, 품질표시 등을 목적으로 부착하는 열 수축성 필름 라벨지(이하,'라벨지'라 함.)의 피복 방법에 관한 것으로, 더욱 구체적으로는 라벨지를 페트병 주면에 열융착 시킴에 있어서 페트병 자체에 순간 고열에 의한 형태변형 등 일체의 악영향을 미치지 않도록 하면서 라벨지의 열융착 공정이 매우 능률적으로 이루어지도록 한 냉각수단을 갖는 페트병의 열 수축성 필름 피복방법 및 그에 따른 냉각수단에 관한 것이다.The present invention relates to a method of coating a heat shrinkable film label paper (hereinafter referred to as "label") mainly attached to the outer surface of the PET bottle for the purpose of indicating the source of the product, quality labeling, etc. More specifically, the label paper main surface Method for coating heat shrinkable film of PET bottle with cooling means which makes the heat fusion process of label paper very efficient while avoiding any adverse effects such as shape deformation due to instantaneous high temperature in PET bottle itself during heat fusion It is about means.
일반적으로 페트병(PET bottle)은 열가소성 폴리에스테르수지를 블로우몰딩(blow molding) 공법으로 제조하여, 주로 탄산음료, 알콜음료, 과즙음료, 간장, 소스 등 액체 음료나 식품용기로 널리 사용되고 있고, 특히 페트병의 재질특성은 투명도가 우수하고 내구성, 내약품성 및 탄력 강도가 양호하여 액체 식품이나 화학제품의 용기로서 그 활용도가 점차 높아지고 있다.In general, PET bottles are manufactured by blow molding method of thermoplastic polyester resin, and are mainly used for liquid drinks or food containers such as carbonated beverages, alcoholic beverages, fruit drinks, soy sauce, sauces, and especially PET bottles. Its material properties are excellent in transparency, durability, chemical resistance and elastic strength is good, and its utilization as a container of liquid food or chemical products is gradually increasing.
이와 같은 페트병의 사용에 있어서는 외면에 제품의 출처표시나 품질표시를 위하여 라벨지(종이라벨지 또는 필름라벨지를 포함한다.)를 부착하게 되는데 종래의 라벨표시방법으로서는 직접인쇄식, 스티커부착식, OPP필름접착식 등이 실시되고 있다.In the use of such PET bottles, a label (including paper label or film label) is attached to the outer surface to indicate the origin of the product or the quality of the product. Conventional labeling methods include direct printing, sticker attachment, and OPP film. Adhesive type etc. are performed.
그러나 상기 표시방법은 다음과 같은 문제점이 있어왔다.However, the display method has the following problems.
페트병에 라벨표시(제조업체 및 품질표시)를 직접인쇄하여 표기하는 방식은 페트병의 사용 후 재활용단계 즉, 회수된 페트병의 분쇄 공정에서 인쇄잉크가 분쇄수지에 혼합되어 재활용수지 색상의 투명도를 크게 저하시키므로 불리하고,The method of directly printing label marking (manufacturer and quality marking) on PET bottles is because the printing ink is mixed with the crushing resin in the recycling stage after the use of PET bottles, that is, the crushing process of the recovered PET bottles, which greatly reduces the transparency of recycled resin color. Disadvantageous,
스티커부착식 라벨표시방법은 스티커 자체가 대부분 지류(紙類)이므로 이 역시 재활용을 위한 분쇄과정에서 스티커 분쇄물이 이물질화되어 불리하며,The sticker labeling method is disadvantageous because the sticker itself is mostly a paper feeder, which is also a foreign matter in the grinding process for recycling.
OPP필름접착방식은 OPP필름(oriented polyoropulene film)에 사용하는 접착제가 환경호르몬을 함유한 고분자 화학접착제 이므로, 이 역시 재활용을 위한 가공 과정에서 환경 호르몬의 배출로 인한 보건위생상 문제점이 야기되었다.OPP film adhesion method is because the adhesive used for OPP film (oriented polyoropulene film) is a high-molecular chemical adhesive containing environmental hormones, this also caused a health hygiene problem due to the release of environmental hormones in the process for recycling.
따라서 페트병의 라벨지로서는 재활용 회수시 박리 제거가 극히 용이한 열 수축성 필름을 이용한 라벨표시방법이 가장 합리적인 방법으로 인식되기에 이르렀다.Therefore, the labeling method using a heat shrinkable film, which is extremely easy to remove and remove during recycling and recovery, has been recognized as the most rational method for PET bottle labels.
다시 말하면, 페트병의 라벨표시방법('라벨포장'을 포함한다.)은 앞으로 국가환경정책상, 자원재활용관계상, 열 수축성 필름에 의한 코팅(피복)방법 이외에는 다른 대안이 없다고 해도 과언이 아니다.In other words, the labeling method of PET bottles (including 'label packaging') is no exaggeration to say that there is no alternative other than the national environmental policy, resource recycling, and coating by heat shrinkable film.
일반적으로 열 수축성 필름은 폴리비닐계(PVC), 폴리에치렌계(PE필름), 폴리프로필렌계(PP필름) 필름을 융점에 가까운 온도에서 일방향 또는 양방향 연신하여 제조하게 되며, 이를 포장재 등으로 사용할 시 외부에서 열을 가하면 필름 전체가 급속히 수축하여 포장기능이나 코팅기능 등을 발휘하게 된다.In general, heat shrinkable film is produced by stretching polyvinyl (PVC), polyethylene (PE film), polypropylene (PP film) film in one or two directions at a temperature close to the melting point, and use it as a packaging material. When heat is applied from outside of the city, the whole film is rapidly contracted to exhibit a packaging function or a coating function.
종래의 경우, 열 수축성 필름에 의한 라벨표시방법은 상기한 필름 자체의 수축기능을 이용하는 것으로, 페트병의 주면에 튜브를 둘러씌운 후 히팅쳄버(3)를 통과시키면 순간 고열에 의해 열 수축성 필름이 스스로 수축되어 페트병의 둘레를 피복하게 되므로, 이때 전가되는 순간 고열온도가 페트병의 융점에 거의 근접하는 관계상, 얇은 페트병 재질의 경우는 상기 순간 가열로 인해 페트병 자체가 부분적으로 변형되는 일이 잦아 페트병 재질을 가급적 두꺼운 재질로 제조하여야 함으로 이로인해 페트병의 제조단가가 높아지고 필요 이상의 초가 중량이 환경부의 친환경정책과도 반대되는 문제점이 따라왔다.In the conventional case, the labeling method using the heat shrinkable film uses the shrinkage function of the film itself. When the heat shrinking film 3 passes through the heating chamber 3 after the tube is covered on the main surface of the PET bottle, the heat shrinkable film itself becomes instantaneous by high heat. Since it shrinks and covers the circumference of the PET bottle, at this time, since the high temperature is almost close to the melting point of the PET bottle when it is transferred, the PET bottle itself is often partially deformed due to the instantaneous heating. As a result, the production cost of PET bottles has increased because of the thick material, and the excess weight more than necessary is contrary to the environmental policy of the Ministry of Environment.
본 발명은 이와 같은 종래의 문제점에 착안하여 페트병 주면에 열 수축성 필름을 씌워 라벨포장을 할 경우, 순간 고열이 미치더라도 페트병 자체에는 아무런 영향을 미치지 않도록 하여 얇은 두께 재질의 페트병일지라도 열 수축성 라벨지의 부착이 매우 용이하게 이루어질 수 있도록 한 새로운 방법을 제안하게 된 것이다.The present invention focuses on such a conventional problem when the label is wrapped with a heat-shrinkable film on the main surface of the PET bottle, even if the instantaneous high temperature does not affect the PET bottle itself so that even if a thin bottle of PET bottle heat-shrinkable labeling A new method was proposed to make this very easy.

상기한 본 발명의 배경기술에 착안하여 본 발명은 페트병의 주면에 열 수축성 필름의 라벨지를 씌워 순간 가열에 의해 열융착시킬 시, 페트병 자체에 고열 온도가 전도되더라도 직접적인 악영향이 미치지 않도록 페트병 내부에 냉각공기를 분사 공급하여 상기한 순간가열에 의한 페트병 자체가 변형됨을 효과적으로 방지할 수 있도록 한 냉각수단을 갖는 페트병의 열 수축성 필름 피복방법 및 그에 따른 냉각수단을 제공하는 데 그 목적이 있다.Focusing on the background of the present invention described above, the present invention covers the inner surface of the PET bottle with a heat-shrinkable film and heats it by instantaneous heating, cooling the inside of the PET bottle so that there is no direct adverse effect even when the high temperature is conducted to the PET bottle itself. It is an object of the present invention to provide a heat shrinkable film coating method of a PET bottle having a cooling means having a cooling means capable of spraying and supplying air to effectively prevent deformation of the PET bottle itself by the instantaneous heating.
본 발명은 상기한 해결과제를 보다 합리적으로 해결하기 위하여 페트병에 열 수축성 필름 라벨지를 씌워서 순간 가열에 의한 라벨지 피복작업을 이행할 시, 페트병 내부에 별도의 냉각 공급 시스템에 의한 냉각공기를 동시에 공급함으로써 라벨지가 상기 순간 가열에 의해 페트병에 수축 피복될 시 페트병 쪽으로는 고열이 직접 전달되지 않도록 하여 페트병 자체의 변형을 효과적으로 방지할 수 있도록 한 것이다.In order to solve the above-mentioned problems more rationally, the present invention is to cover the PET bottle with heat shrinkable film label paper and to simultaneously supply the cooling air by a separate cooling supply system to the inside of the PET bottle when performing the label coating work by instant heating. When the label is shrink-coated to the PET bottle by the instantaneous heating, the high heat is not directly transmitted to the PET bottle so that the deformation of the PET bottle itself can be effectively prevented.
페트병의 라벨지를 열 수축성 라벨지로 피복 할 경우, 페트병을 1차 사용 후 회수하여 재활용하게 될 시 라벨지가 매우 용이하게 박리될 수 있는 장점이 있으므로 열 수축성 필름에 의한 라벨지의 부착방법이 가장 바람직한 방법으로 인식되고 있는바, 본 발명은 이와 같은 열 수축성 필름을 사용한 라벨지 코팅작업시 페트병 내부에 별도의 냉각공기공급시스템에 의한 냉각공기를 동시에 공급할 수 있도록 함으로써, 외부에서 열 수축성 필름의 응축 작업을 위한 고열이 복사열로 전달될 시, 이 열기는 열 수축성 필름의 수축 기능에만 영향을 미치게 하고, 페트병 자체에는 아무런 영향을 미치지 않도록 하여 라벨 코팅 공정 중에 페트병 자체의 변형 등으로 인한 불량품이 발생하지 않도록 한 것이다.When labeling PET bottle labels with heat-shrinkable labels, the label can be easily peeled off when the PET bottle is recovered and recycled after the first use. It is recognized that the present invention is to provide a cooling air by a separate cooling air supply system at the same time inside the PET bottle during the label coating work using such a heat shrinkable film, high heat for the condensation of the heat shrinkable film from the outside When transferred to this radiant heat, this heat only affects the shrinkage function of the heat shrinkable film and does not affect the PET bottle itself so that no defectives are caused by the deformation of the PET bottle itself during the label coating process.
상기한 효과에 의해 페트병의 두께를 얇게 제조하더라도 라벨지의 피복작업과정에서 발생되는 고열이 페트병에 아무런 영향이 미치지 않으므로 특히 1회용 페트병의 공급에 따른 수지재료 절감에 크게 기여할 수 있고, 자원재활용 및 환경 보전에도 크게 일조할 수 있는 등 여러가지 산업적인 효과가 따른다.Even if the thickness of the PET bottle is manufactured by the above effects, the high heat generated during the coating process of the label does not affect the PET bottle, and in particular, it can greatly contribute to the reduction of the resin material according to the supply of the disposable PET bottle. There are various industrial effects that can greatly contribute to conservation.

도 1은 본 발명의 구체적인 기술적 방법을 설명하기 위하여 종래의 수축 라벨지의 열융착 과정을 보인 예시도를 나타낸 것이다.Figure 1 shows an exemplary view showing the heat-sealing process of the conventional shrink label in order to explain the specific technical method of the present invention.
종래의 방법은 페트병(1)의 주면에 제품의 출처표시, 품질표시 등이 인쇄된 튜브형의 열 수축성 필름 즉, 라벨지(2)를 피복 코팅시킴에 있어서, 1차 공정에서 페트병(1) 주면에 라벨지(2)를 둘러씌운 다음 히팅쳄버(heating chamber)(3)을 통과시키는 2차 공정에서 라벨지(2)의 주면에 고열의 열풍을 가하여 상기 라벨지(2)가 페트병(1) 주면에서 수축되면서 열융착이 자연스럽게 이루어지도록 하는 것이다.The conventional method is to coat and coat a tubular heat shrinkable film, that is, a label 2, on which the main surface of the PET bottle 1 is labeled with a product source mark, a quality mark, etc., on the main surface of the PET bottle 1 in the first step. In the secondary process of enclosing the label paper (2) and passing the heating chamber (3), a high-temperature hot air is applied to the main surface of the label paper (2) so that the label paper (2) shrinks on the main surface of the PET bottle (1). The thermal fusion is to be made naturally.
그런데 상기한 공정은 수축 라벨지(2)의 히팅 과정에서 페트병(1) 자체도 일정온도 고열의 영향을 받게 되므로 얇은 페트병(1) 재질의 경우는 불규칙하게 페트병(1)의 자체변형이 일어나는 요인과, 라벨지가 열수축되는 과정에서 발생되는 수축압에 의해 페트병(1)에 변형이 일어나므로 페트병(1)의 재질두께가 두꺼운 경우에만 수축 라벨지(2)의 피복이 가능하였다.However, in the above process, since the PET bottle 1 itself is also affected by a constant temperature and high temperature during heating of the shrink label 2, in the case of a thin PET bottle 1, irregular deformation of the PET bottle 1 occurs and Since the deformation occurs in the PET bottle 1 due to the shrinkage pressure generated in the process of the heat shrinkage of the label, it is possible to coat the shrink label 2 only when the material thickness of the PET bottle 1 is thick.
본 발명은 상기한 종래 방법에 착안하여 페트병(1)에 수축 라벨지(2)를 둘러씌워 히팅쳄버(3)을 통과하는 시점에 맞추어 페트병(1) 내부에 상기 히팅 열기에 대응하도록 냉각공기를 페트병(1) 내부에 동시 공급함으로써 수축 라벨지의 히팅 온도가 페트병(1) 자체에는 아무런 영향을 미치지 못하도록 한 것이다.The present invention focuses on the above-described conventional method to cover the shrink label (2) on the PET bottle (1) to match the heating heat inside the PET bottle (1) in accordance with the time passing through the heating chamber (3) PET bottle (1) By simultaneously supplying the inside, the heating temperature of the shrink label does not affect the PET bottle 1 itself.
또한, 페트병(1) 내부에 냉각공기를 일정량만큼 주입하게 되면, 페트병(1)내에 냉각공기에 의한 공기압이 형성되어 페트병(1)의 형태를 잡아주게 됨으로써, 수축 라벨지의 열 수축시 발생되는 수축압이 페트병(1) 자체에 아무런 영향을 미치지 못하도록 한 것이다.In addition, when a predetermined amount of cooling air is injected into the PET bottle 1, air pressure is formed by the cooling air in the PET bottle 1, thereby holding the shape of the PET bottle 1, and thus the shrinkage pressure generated during thermal shrinkage of the shrink label paper. The PET bottle (1) is to have no effect on itself.

또한, 재질두께가 많이 얇은 패트병(1)의 경우 냉각공기를 주입하여 수축 라벨지(2)의 열처리시에 냉각공기공급관(5)을 통해 냉각공기를 패트병(1) 내부에 일정량 공급하여 패트병 내부에서 냉각공기압을 형성하여 패트병의 형태를 잡아주도록 함으로써 라벨지의 열수축 과정에서 발생되는 수축압이 패트병의 형상 변형시킬 수 있는 요인을 효과적으로 방지하게 된다.In addition, in the case of a plastic bottle (1) having a very thin material thickness, cooling air is injected into the plastic bottle (1) to supply a predetermined amount of cooling air through the cooling air supply pipe (5) during heat treatment of the shrink label (2). By forming the cooling air pressure to hold the shape of the plastic bottle, the shrinkage pressure generated during the heat shrinkage process of the label paper can effectively prevent the factor that can deform the shape of the plastic bottle.
