본 발명은 액체 스프 포대에 관계되는 것으로서, 특히 나일론 필름에 LLDPE 필름을 적층시킨 적층 필름으로 구성된 개봉이 용이한 액체 스프 포장용 필름으로 구성된 액체 스프 포대에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid soup bag, and more particularly, to a liquid soup bag composed of an easy-opening liquid soup packaging film composed of a laminated film in which an LLDPE film is laminated on a nylon film.

종래에는 액체 스프를 포장하기 위하여 포장 필름 속에 일정량의 스프를 주입한 후에 접착시키는 방법으로 포장하였으므로 포장 시간이 오래 걸리는 문제점이 있었다. 특히 종래의 방법에 의하면 포장 봉투의 용량에 비하여 소량만의 액체 스프가 주입되도록 되었으며, 가열 압착하여 밀봉되는 부분에 액체 스프가 소량 묻어 있는 경우에는 협착 부분이 완전히 밀봉되도록 밀착되지 않는 문제점이 나타났다.In the related art, packaging is made by injecting a certain amount of soup into a packaging film and then bonding the liquid soup to package the liquid soup, thereby causing a long packaging time. Particularly, according to the conventional method, only a small amount of liquid soup is injected as compared to a capacity of a packaging bag, and when a small amount of liquid soup is buried in a portion sealed by heat pressing, a problem in that the constriction part is not completely sealed appears.

이러한 종래의 문제점을 개선하기 위하여 최근에는 나일론 필름과 LLDPE 필름으로 구성된 적층 필름을 사용하는 포장 방법이 개발되었다. Recently, a packaging method using a laminated film composed of a nylon film and an LLDPE film has been developed to improve this conventional problem.

최근에 개발된 방법에 따르면, 액체 스프 포장은 80∼90℃로 가열된 액체 스프를 포장 필름 속으로 흘려보내면서 일정한 용량이 충전되면 필름의 중간 부분에서 가열 압착하여 액체 스프를 포장하는 방법으로 포장하고 있다.According to a recently developed method, liquid soup packaging is a method of packaging liquid soup by heating and compressing the liquid soup heated to 80-90 ° C. into a packaging film, and then compressing the liquid soup by heating and compressing it in the middle portion of the film. Doing.

이러한 액체 스프 포대는 최소한 50kg의 정압에서도 봉투가 파손되지 않아야 함은 물론이고 액체 스프가 묻어 있는 부분에서도 가열 압착에 의하여 밀봉 압착되어야 한다. 이러한 조건은 연질의 나일론/LLDPE 적층 필름을 사용하면 해결되는 것으로 알려져 있어서 대부분의 액체 스프 포장에는 나일론/LLDPE 적층 필름을 사용하고 있다.Such liquid soup sacks should be sealed and compressed by hot pressing in the liquid soup part as well as the bag not to be broken at a static pressure of at least 50 kg. This condition is known to be solved by using a soft nylon / LLDPE laminated film, and most liquid soup packaging uses a nylon / LLDPE laminated film.

그러나 이러한 나일론/LLDPE 적층 필름을 사용하는데도 문제점이 나타났다. 나일론/LLDPE 필름은 개봉할 때 필름의 개봉 부위에서 잘 찢어지지 않는 문제점이 있다. 특히 액체 스프 포장시에는 액체 스프가 거의 봉투에 충만 된 상태로 포장하므로 찢을 때 잘못 찢으면 액체 스프가 옆으로 튀어나와서 봉투를 찢는 사람의 의복을 오염시키는 경우가 나타났다.However, problems have also been shown in using such nylon / LLDPE laminated films. Nylon / LLDPE film has a problem that it does not tear easily at the opening of the film when opening. In particular, when packing liquid soups, liquid soups are almost filled in bags, so if they are torn incorrectly, the liquid soup pops out to the side and contaminates the clothing of the person who tears the bags.

이러한 불편한 점을 해소하기 위하여 스프 포장용 합성수지 포대를 찢는 부분인 용착 부분에 절개부를 형성하여 용이하게 찢어지도록 하는 방법이 시도되고 있다. 이 방법은 찢는 부분의 용착 부위에 포대 내부로부터 2mm 정도의 여분을 남겨놓고 칼로 절개부를 형성하는 것으로서 현재까지는 가장 많이 사용되는 방법이라 할 수 있다. 그러나 이 방법에 의하면 절개부를 형성한 부분까지는 용이하게 찢어지지만 절개부가 형성되지 않은 부분에 도달하면 쉽게 찢어지지 않게 되는 문제점이 나타나게 된다. 특히 액체 스프는 소량의 고형분을 포함하고 있고 스프를 포장할 때 포대 내부로 액체 스프를 흘려보내면서 가로방향으로 용착하므로 용착 부분에 미량의 고형분이 존재하는 경우 포대의 강도가 약하여지게 되어 요구하는 강도를 얻을 수 없게 된다는 문제점이 나타났다. In order to alleviate this inconvenience, a method of making an incision in the welded portion which tears the synthetic resin bag for soup packaging is easily tried. This method is the most widely used method to form the incision with a knife leaving a spare of about 2mm from the inside of the bag at the welding portion of the tearing portion. However, according to this method, even if the incision is easily torn to the part where the incision is formed, the problem of not being easily torn when reaching the part where the incision is not formed appears. In particular, liquid soups contain a small amount of solids, and when they are packed, the liquid soup is welded in the horizontal direction while flowing the liquid soup into the bag. Therefore, when there is a small amount of solids in the welded portion, the strength of the bag becomes weak. The problem is that it can not be obtained.

이러한 불편한 점을 해소하고 나일론/LLPDE 적층 필름으로 구성된 봉투가 방향성을 갖고 일정한 방향으로 용이하게 찢어지도록 하기 위하여 나일론 필름 층에 레이저를 이용하여 미세한 구멍을 형성함으로서 봉투가 용이하게 찢어지도록 하는 방법이 연구되었다. 이러한 방법에 의하면 봉투가 용이하게 찢어지는 이점은 있으나 나일론 필름의 다공화에 의하여 나일론 필름 층의 강도가 약화되므로 운송 도중 모서리 부분이 쉽게 파손되는 문제점이 나타남을 알게 되었다. 특히 레이저를 이용하여 나일론 필름 층을 다공성으로 형성하는 방법은 LLDPE 필름에 의하여 밀폐 효과가 나타나도록 하는 것이므로 시간이 경과하여 LLPDE 필름 층이 노화되는 경우 LLPDE 필름 층의 기밀성이 약화되어 포대의 완전한 밀봉을 기대하기 어려워서 식용유 성분을 갖는 스프의 경우 포장된 내용물이 산패될 위험성이 나타나게 된다. In order to solve this inconvenience and to make the envelope composed of nylon / LLPDE laminated film to be directional and easily torn in a certain direction, a method of making the envelope easily tear by forming minute holes using a laser in the nylon film layer is studied. It became. According to this method, there is an advantage that the envelope is easily torn, but the strength of the nylon film layer is weakened by the porosity of the nylon film, so that the corner portion is easily broken during transportation. In particular, the method of forming the nylon film layer porous by using laser is such that the sealing effect is exhibited by the LLDPE film. Therefore, if the LLPDE film layer ages over time, the airtightness of the LLPDE film layer is weakened, so that the bag is completely sealed. Unexpectedly, soups with cooking oils present a risk of rancidity of the packaged contents.

따라서 필름 자체의 물성에 변화를 주지 않으면서 용이하게 찢어지는 나일론 필름/LLDPE 필름 적층 필름으로 구성된 개봉이 용이한 액체 스프 포대가 요구되고 있는 실정이다.Therefore, there is a demand for an easy opening liquid soup bag composed of a nylon film / LLDPE film laminated film that is easily torn without changing the physical properties of the film itself.

본 발명은 액체 스프 포대를 제조하기 위한 나일론 필름/LLDPE 필름으로 구성된 액체 스프 포대에 있어서, 방향성을 갖고 용이하게 찢어지는 개봉이 용이한 액체 스프 포대를 얻기 위한 것이다.The present invention is to obtain a liquid soup bag that is directional and easily torn in a liquid soup bag composed of a nylon film / LLDPE film for producing a liquid soup bag.

전술한 본 발명의 목적은 나일론 필름/LLDPE 필름으로 구성된 액체 스프 포대에 있어서, 나일론 필름의 표면 또는 이면에 파열 수지층이 형성되고 나일론 필름에 드라이 라미네이션 방법에 의하여 LLDPE 필름이 적층 된 적층 필름으로 구성된 본 발명의 개봉이 용이한 액체 스프 포대에 의하여 달성된다.The above object of the present invention is a liquid soup bag composed of a nylon film / LLDPE film, wherein a rupture resin layer is formed on the surface or the back of the nylon film and the LLDPE film is laminated on the nylon film by a dry lamination method. The opening of the present invention is accomplished by an easy liquid soup bag.

본 발명은 나일론 필름/LLDPE 필름을 적층시켜서 된 액체 스프 포대에 있어서, 나일론 필름의 표면 또는 이면에 고형 분산제가 함유된 파열 수지층이 형성되고 나일론 필름과 LLDPE 필름을 드라이 라미네이션 방법으로 적층시켜서 된 적층 필름으로 형성된 액체 스프 포대로 구성된다.The present invention relates to a liquid soup bag obtained by laminating a nylon film / LLDPE film, wherein a burst resin layer containing a solid dispersant is formed on the surface or the back of the nylon film, and the nylon film and the LLDPE film are laminated by a dry lamination method. Consists of a liquid soup bag formed into a film.

본 발명에 따르면, 파열 수지층은 고형 분산제를 포함하는 합성수지를 그래비아 인쇄와 같은 통상적인 인쇄방법으로 인쇄하여 형성하는바, 고형 분산제로는 산화티타늄을 사용하는 것이 가장 바람직하다. 그러나 고형 분산제로 티타늄 외에 카본불랙이나 활석 분말도 사용할 수 있다. 바람직한 인쇄 잉크로는 산화티탄 5∼30중량%, 바람직하게는 10∼30중량%를 포함하는 합성수지계통의 백색 잉크가 바람직하다. 카본블랙을 포함하는 흑색 잉크의 경우는 카본블랙을 최소한 3∼15중량% 포함하는 것이 바람직한 것으로 나타났다. 그러나 경우에 따라서는 무색 분말상 분산제를 포함하는 잉크도 사용할 수 있다. 전술한 파열 수지층은 유색 인쇄층의 형태로 형성될 수도 있고 무색 합성수지층으로 형성할 수도 있다.According to the present invention, the bursting resin layer is formed by printing a synthetic resin including a solid dispersant by a conventional printing method such as gravure printing, and it is most preferable to use titanium oxide as the solid dispersant. However, in addition to titanium, carbon black or talc powder may be used as the solid dispersant. The preferred printing ink is a synthetic resin-based white ink containing 5 to 30% by weight of titanium oxide, preferably 10 to 30% by weight. In the case of black ink containing carbon black, it has been found to contain at least 3 to 15% by weight of carbon black. However, in some cases, an ink containing a colorless powdery dispersant may also be used. The above-mentioned bursting resin layer may be formed in the form of a colored printing layer or may be formed of a colorless synthetic resin layer.

본 발명자의 판단에 의하면 파열 수지층에 함유된 고체 분말상 분산제가 포대가 잘 찢어지도록 돕는 것으로 판단된다. 따라서 파열 수지층에는 고형 분말상 충전제가 함유되는 것이 필수적이다.According to the judgment of the present inventors, it is judged that the solid powdery dispersant contained in the bursting resin layer helps the bag to be torn off well. Therefore, it is essential that the bursting resin layer contains a solid powdery filler.

파열 수지층은 나일론 필름의 내면, LLDPE 필름과 나일론 필름 층 사이에 형성하는 것이 바람직하다.The bursting resin layer is preferably formed between the inner surface of the nylon film and the LLDPE film and the nylon film layer.

본 발명에 의하면 나일론 필름은 12∼25㎛의 두께를 갖는 것을 사용하고, LLDPE 필름은 35∼70㎛의 두께를 갖는 것을 사용한다. 파열 수지층은 0.25∼5.0㎛의 두께를 갖도록 도포한다. 전술한 파열 수지층은 나일론 필름의 내면에 100gf/15mm 이상의 접착 강도를 갖도록 도포한다. According to the present invention, a nylon film having a thickness of 12 to 25 µm is used, and an LLDPE film having a thickness of 35 to 70 µm is used. The bursting resin layer is applied to have a thickness of 0.25 to 5.0 µm. The ruptured resin layer described above is applied to the inner surface of the nylon film to have an adhesive strength of 100 gf / 15 mm or more.

파열 수지층은 나일론 필름의 전면에 도포할 수도 있으나, 바람직한 것은 개봉 부위에만 도포하는 것이 경제적으로 유리하다.Although the bursting resin layer may be applied to the entire surface of the nylon film, it is economically advantageous to apply only to the unsealed portion.

이하 본 발명을 도면에 의하여 상세하게 설명한다.Hereinafter, the present invention will be described in detail with reference to the drawings.
