일반적으로 은나노는 은이 분쇄되어 나노크기로 미립자화된 것으로 원적외선을 발생시키고, 살균 및 항균작용을 수행하는데 탁월한 기능을 발휘함에 따라 다양한 분야에 적용되어 사용되고 있다.In general, silver nano-particles are pulverized into nano-sized particles to generate far-infrared rays, and have excellent functions in performing sterilization and antibacterial effects.

상기와 같은 기능을 가진 은나노는 위생상 청결유지와 부패 및 세균침투방지가 중요한 식품포장에도 적용되어 사용되는데, 포장지를 제조하는데 사용되는 필름에 상기 은나노를 첨가시켜 사용하고 있다.Silver nano having the same function is used in food packaging, which is important for hygienic cleanliness maintenance and prevention of decay and bacterial penetration, is used by adding the silver nano to the film used to manufacture the wrapping paper.

상기 은나노가 첨가된 포장용 필름으로는 합성수지로 된 필름의 일측 표면에 은나노가 일정두께로 코팅된 것과, 합성수지와 은나노가 혼합된 후 일체형의 필름으로 성형된 것이 있다.The silver nano-packaged packaging film may be formed by coating silver nano with a predetermined thickness on one surface of a film made of synthetic resin, and then forming a monolithic film after mixing synthetic resin and silver nano.

그러나, 은나노가 코팅된 포장용 필름은 합성수지로 된 필름에 은나노를 코팅하기 위한 접착물질이 사용되는데, 이러한 접착물질은 은나노의 함량을 떨어뜨리게 하는 문제점이 있다. 즉, 은나노의 함량이 많으면 수지층에 접착이 불량하여 사용중에 은나노 코팅이 쉽게 떨어지는 문제점이 있고, 은나노 코팅의 접착력을 높이기 위하여 접착제의 함량을 높이게 되는데 경우는 은나노의 함량이 적어져 식품의 보존성을 떨어뜨리는 문제점이 있게 된다.However, the silver nano-coated packaging film is used for the adhesive material for coating the silver nano film on the film made of synthetic resin, this adhesive material has a problem of lowering the content of silver nano. In other words, if the content of silver nano is high, there is a problem that the silver nano coating is easily dropped during use due to poor adhesion to the resin layer, and the content of the adhesive is increased to increase the adhesive strength of the silver nano coating. There is a problem of dropping.

그리고 합성수지와 은나노가 혼합 성형된 포장용 필름은 필름 전체에 걸쳐 은나노가 분포하게 되는데, 은나노는 실제 포장물품과 접촉하여 기능을 수행하게 되므로, 은나노가 기능을 수행하지 못하는 부분에까지 분포되어 실제적인 기능수행이 저하한 문제가 있었다.In the packaging film in which the synthetic resin and the silver nano are mixed and formed, silver nano is distributed throughout the film. Since silver nano is in contact with the actual packaged product, the silver film is distributed to a portion where the silver nano does not perform a function. There was a problem that was degraded.

본 발명의 목적은 상기와 같은 문제점을 해결하기 위한 것으로 은나노와 합성수지가 혼합된 은나노수지층과, 합성수지만으로 형성된 다수개의 합성수지층이 적층되되 은나노수지층이 최외곽층이 되도록 하여 필름으로 열융착됨으써 식품과 접촉되는 층이 은나노가 다량으로 함유되어 세균이나 곰팡이 등과 접촉하여 항균, 살균, 탈취작용의 기능이 극대화될 뿐만 아니라, 은나노수지층과 합성수지층이 적층되어 열융착으로 일체로 형성됨으로써 접합된 층 사이에 작용하는 장력에 의해 포장용 필름의 강도가 높아진 고밀도 은나노 표면층을 가진 포장용 필름 및 그 제조방법을 제공함에 있다.An object of the present invention is to solve the above problems, the silver nano resin layer mixed with silver nano and synthetic resin, and a plurality of synthetic resin layers formed of only synthetic resin is laminated so that the nano nano resin layer is the outermost layer is heat-sealed into the film As the layer in contact with food contains a large amount of silver nano, it is in contact with bacteria or mold to maximize the function of antibacterial, sterilization and deodorization, and the silver nano resin layer and synthetic resin layer are laminated and formed integrally by heat fusion. The present invention provides a packaging film having a high-density silver nano surface layer whose strength of the packaging film is increased by the tension acting between the layers.

이하 본 발명을 첨부도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 발명의 고밀도 은나노 표면층을 가진 포장용 필름은 최외곽의 내측에 위치된 은나노수지층(1)과, 상기 은나노수지층(1)에 순차적으로 적층된 다수개의 합성수지층(2)이 열융착으로 하나의 필름으로 일체로 형성됨을 특징으로 한다.Packaging film having a high-density silver nano surface layer of the present invention is a silver nano resin layer (1) located on the innermost outermost side, and a plurality of synthetic resin layers (2) sequentially laminated on the silver nano resin layer (1) by heat fusion It is characterized in that it is formed integrally with the film.

은나노수지층(1)은 은나노(3)와 합성수지입자(4)가 혼합성형된 것이고, 합성수지층(2)은 합성수지만으로 형성된 층이다.The silver nano resin layer 1 is a mixture of silver nano 3 and synthetic resin particles 4, and the synthetic resin layer 2 is a layer formed of only synthetic resin.

그리고 은나노수지층(1)을 형성하는 합성수지와 합성수지층(2)을 구성하는 합성수지는 동일한 재질이어야 함이 바람직하다. 즉 상기의 합성수지는 PE(폴리에틸렌), PP(폴리프로필렌), PS(폴리스틸렌), PVC(폴리염화비닐), EVA(에틸렌초산비닐), PET(폴리에틸렌 테레프탈레이트) 등에서 선택되되 동일한 하나의 재질만이 선택된다.In addition, the synthetic resin forming the silver nano resin layer 1 and the synthetic resin forming the synthetic resin layer 2 are preferably made of the same material. In other words, the synthetic resin is selected from PE (polyethylene), PP (polypropylene), PS (polystyrene), PVC (polyvinyl chloride), EVA (ethylene vinyl acetate), PET (polyethylene terephthalate), etc. Is selected.

또한 은나노수지층(1)은 상기의 합성수지에 은나노(3)가 10~100ppm의 농도로 분산 배합된 것이다.In the silver nano resin layer 1, silver nano 3 is dispersed and blended in the synthetic resin at a concentration of 10 to 100 ppm.

이와 같이 본 발명은 합성수지층(2)에 접착제로 은나노(3)가 코팅된 것이 아니라, 은나노(3)가 포함된 은나노수지층(1)이 다른 다수장의 합성수지층(2)과 열융착으로 하나의 필름으로 융착되어 형성됨으로써, 접착제의 기능저하로 은나노(3)가 떨어지는 것이 근원적으로 방지되고, 은나노(3)가 최외측에 밀집되게 형성됨으로써 항균 및 살균 등의 기능성이 향상된다.As described above, the present invention is not coated with silver nanoparticles (3) with an adhesive on the synthetic resin layer (2), but the silver nano resin layer (1) containing silver nanoparticles (3) is one of a plurality of synthetic resin layers (2) by thermal fusion. By fusion is formed by the film of the film, the fall of the silver nano (3) is fundamentally prevented by the deterioration of the adhesive, and the silver nano (3) is densely formed on the outermost side to improve the functionality such as antibacterial and sterilization.

그리고 본 발명은 은나노(3)가 고밀도로 집적된 얇은 은나노수지층(1)이 식품 포장용 필름(100)의 최내층을 형성하고 있으므로, 포장용 필름(100) 전체에 걸쳐 동일한 은나노(3)입자를 가지더라도 단위면적당의 은나노(3) 밀도는 현저히 저하되는 종래의 것에 비하여, 본원 발명의 포장용 필름(100)은 식품의 보존성과 살균 및 항균의 기능에 있어 뛰어는 효능을 가짐이 당연하게 된다.In the present invention, since the thin silver nano resin layer 1 in which the silver nano 3 is integrated at a high density forms the innermost layer of the film 100 for food packaging, the same silver nanoparticles 3 are used throughout the packaging film 100. Even if it has a silver nano (3) density per unit area, the packaging film 100 of the present invention is excellent in the preservation of food, sterilization and antimicrobial functions of the present invention is natural.

상기와 같이 구성 및 기능을 가진 본 발명의 포장용 필름(100)은 다음과 같은 단계로 제조된다. Packaging film 100 of the present invention having the configuration and function as described above is manufactured in the following steps.

PE, PP, PS, PVC, EVA, PET 등의 합성수지입자(4)에 은나노(3)가 10~100ppm의 농도로 분산 배합되게 혼합하여 은나노수지층(1)을 성형하는 단계와, 상기 은나노수지층(1)을 구성하는 소재와 동일한 합성수지입자(4)로 합성수지층(2)을 성형하는 단계와, 상기에서 성형된 은나노수지층(1)을 최외측의 내층이 되게 하고 그 위에 합성수지층(2)을 여러장 적층시키는 단계와, 적층된 은나노수지층(1)과 합성수지층(2)을 열롤러(5)를 이용하여 열융착하여 일체로 접합하는 단계를 거쳐 제조된다.The silver nano resin layer (1) is formed by mixing and dispersing the silver nanoparticles (3) in a concentration of 10 to 100 ppm to the synthetic resin particles (4) such as PE, PP, PS, PVC, EVA, PET, and the silver nano water. Molding the synthetic resin layer 2 with the same synthetic resin particles 4 as the material constituting the ground layer 1, and making the silver nano resin layer 1 formed above the outermost inner layer, 2) a plurality of layers and the laminated silver nano resin layer (1) and the synthetic resin layer (2) using the heat roller (5) by the step of thermally bonding and integrally produced.

상기에서 은나노수지층(1)과 합성수지층(2)을 압출성형하는 것은 동시에 행할 수도 있고, 별도로 행하여 적층시켜 열융착시킬 수도 있으나 제조상의 자동화와 생산성 향상을 위하여 동시에 성형하는 것이 바람직하고, 동시 성형의 경우는 합성수지층(2)이 여러장 적층되기 때문에 여러대의 장치가 필요함은 당연하다.The silver nano resin layer (1) and the synthetic resin layer (2) may be extruded at the same time, or may be separately carried out to be laminated and heat-sealed, but it is preferable to simultaneously mold for automation and productivity improvement in manufacturing. In the case of, since the synthetic resin layer 2 is laminated several sheets, it is natural that several devices are required.

여기서, 은나노수지층(1)과 합성수지층(2)의 성형은 압출기(6)를 이용할 수 있는데, 은나노수지층(1)의 경우는 은나노(3)와 합성수지입자(4)가 서로 혼합된 소재가 압출기(6)를 통과함으로써 미세두께로 성형되고, 합성수지층(2)의 경우는 합성수지입자(4)가 압출기(6)를 통과함으로써 미세두께로 성형된다.Here, the molding of the silver nano resin layer 1 and the synthetic resin layer 2 may use an extruder 6. In the case of the silver nano resin layer 1, the silver nano resin 3 and the synthetic resin particles 4 are mixed with each other. Is molded to a fine thickness by passing through the extruder 6, and in the case of the synthetic resin layer 2, the synthetic resin particles 4 are molded to a fine thickness by passing through the extruder 6.

그리고 적층하여 열융착시키는 단계는 서로 맞물리면서 일정속도로 회전하는 한쌍의 열롤러(5)로 통과시켜 상기 은나노수지층(1)과 합성수지층(2)이 열융착시되게 함으로써 다수층이 일체로 단단하게 접합되게 포장용 필름(100)을 제조하게 된다. 물론 상기 은나노수지층(1)과 합성수지층(2)은 동일한 합성수지 소재로 되어 있어 열융착에 의한 접합이 용이하게 이루어지고, 은나노수지층(1)과 합성수지층(2)은 열롤러(5)에 의해 융착되는 과정에서 일정부피가 압착되면서 접합됨에 따라 포장용 필름(100)의 강도가 더욱 증대되게 된다.And the step of laminating and heat fusion is passed through a pair of heat rollers 5 which rotate at a constant speed while interlocking with each other to allow the silver nano resin layer 1 and the synthetic resin layer 2 to be heat-sealed so that a plurality of layers are integrally united. The packaging film 100 is manufactured to be bonded. Of course, the silver nano resin layer 1 and the synthetic resin layer 2 are made of the same synthetic resin material, so that the bonding is easily performed by thermal fusion, and the silver nano resin layer 1 and the synthetic resin layer 2 are thermal rollers 5. As a certain volume is pressed while being bonded in the process of fusion, the strength of the packaging film 100 is further increased.

이와 같이 제조된 본 발명의 포장용 필름(100)은 부패되거나 세균에 의해 감염될 시 인체에 해로운 영향을 끼칠 수 있는 식품 등을 포장하는데 주로 사용되는 것으로 진공포장, 위생포장, 스텐딩파우치, 레트로트파우치 등 다양한 형태의 식품 포장지를 제작하는데 사용된다.The packaging film 100 of the present invention prepared as described above is mainly used to package foods that may have a harmful effect on the human body when rotted or infected by bacteria. Vacuum packaging, sanitary packaging, standing pouch, retro pouch It is used to make various types of food wrapping paper.

포장용 필름(100)은 도 1과 같이 은나노(3)와 합성수지입자(4)가 혼합된 은나노수지층(1)이 얇은 두께로 포장용 필름(100)의 내층을 이루도록 하여 포장물품과 접촉되는 면에 은나노(3)가 밀집됨으로써 세균이나 곰팡이 등과 접촉하여 항균, 살균, 탈취작용 등을 수행하는 은나노(3)의 기능이 극대화된 것이다.As shown in FIG. 1, the packaging film 100 has a silver nano resin layer 1 in which silver nano 3 and synthetic resin particles 4 are mixed to form an inner layer of the packaging film 100 in a thin thickness, so as to contact the packaged article. As the nano silver (3) is concentrated, the function of the silver nano (3) to perform antibacterial, sterilization, deodorization, etc. in contact with bacteria or fungi is maximized.

그리고 본 발명의 포장용 필름(100)은 상기 은나노수지층(1)에 한개 이상의 합성수지층(2)이 접합되어 다수층으로 구성됨으로써 서로 접합된 층 사이에 작용하는 장력에 의해 포장용 필름(100)의 강도가 높아진다.And the packaging film 100 of the present invention is composed of a plurality of layers by bonding one or more synthetic resin layer (2) to the silver nano resin layer (1) of the packaging film 100 by the tension acting between the layers bonded to each other Strength is increased.

또한 은나노수지층(1)은 은나노(3)가 내마모성의 PE, PP, PS, PVC, EVA, PET 등과 같은 합성수지입자(4)에 분산 배합되어 있음에 따라, 은나노수지층(1)과 포장물품이 직접 접촉하여 마찰하더라도 은나노수지층(1)이 쉽게 마모되지 않아 은나노(3)가 지속적으로 보호되면서 기능을 수행하게 된다.In addition, the silver nano resin layer 1 is a silver nano resin layer (1) and the packaged article as the silver nano (3) is dispersed and blended in the synthetic resin particles (4), such as wear-resistant PE, PP, PS, PVC, EVA, PET, etc. The silver nano resin layer (1) is not easily worn even when the friction is in direct contact with the silver nano resin (3) to perform a function while being continuously protected.

그리고 은나노수지층(1)은 얇은 두께로 성형됨에 따라 포장용 필름(100)의 강도를 높이기 위해 상기 은나노수지층(1)의 상면에 일정두께의 합성수지층(2)이 층합되는데, 상기 합성수지층(2)은 은나노수지층(1)을 구성하는 합성수지와 동일한 소재로 되어 있어 은나노수지층(1)과 열융착시 용이하게 일체로 접합된다.And the silver nano resin layer (1) is molded in a thin thickness in order to increase the strength of the packaging film 100, the synthetic resin layer (2) of a predetermined thickness is laminated on the upper surface of the silver nano resin layer (1), the synthetic resin layer ( 2) is made of the same material as that of the synthetic resin constituting the silver nano resin layer 1 and is easily integrally bonded to the silver nano resin layer 1 during thermal fusion.

본 발명에 일실시예가 도시된 도 1과 도 2에서는 은나노수지층(1)에 두개의 합성수지층(2)이 적층되어 접합되어 있으나, 그 적층의 갯수는 필요에 따라 선택된다.1 and 2 show an embodiment of the present invention, two synthetic resin layers 2 are laminated and bonded to the silver nano resin layer 1, but the number of the stacks is selected as necessary.

상기와 같이 본 발명의 포장용 필름(100)은 다수층이 일체로 접합됨으로써 은나노수지층(1)과 합성수지층(2) 사이의 접합면에 서로를 당기는 장력이 발생하게 되는데, 상기 장력이 포장용 필름(100)을 구성하는 각 층을 서로 당겨줌으로써 포장용 필름(100)의 강도가 높아지게 되어, 포장물품을 포장한 후 장시간 운반하더라도 포장지를 이루는 포장용 필름(100)이 포장물품의 무게에 의해 찢어지거나, 변형되어 손상되는 일이 방지된다.As described above, in the packaging film 100 of the present invention, a plurality of layers are integrally bonded to each other to generate a tension pulling each other on the bonding surface between the silver nano resin layer 1 and the synthetic resin layer 2, wherein the tension is a packaging film. By pulling each layer constituting the (100) with each other, the strength of the packaging film 100 is increased, even if the packaging is transported for a long time after packaging the packaging film 100 forming the packaging is torn by the weight of the packaging article, It is prevented from being deformed and damaged.

이와 같이 된 본 발명은, 은나노(3)가 식품 포장용 필름(100)의 내측면에 고밀도로 위치하도록 은나노(3)가 고밀도로 집적된 은나노수지층(1)을 별도로 제조하여 합성수지층(2)에 열융착시킴으로써 항균, 살균, 탈취작용 등을 수행하는 은나노(3)의 기능이 극대화되고, 상기 은나노수지층(1)에 다수개의 합성수지층(2)이 접합되어 포장용 필름(100)을 형성함으로써 서로 접합된 층 사이에 작용하는 장력에 의해 포장용 필름의 강도가 높아져 내구성이 증대되는 효과가 있다.In the present invention as described above, the silver nano resin layer 3 is a high density integrated silver nano resin layer (1) so that the silver nano 3 is located on the inner surface of the food packaging film 100 in a high density, the synthetic resin layer (2) By heat-sealing to maximize the function of the silver nano (3) to perform antibacterial, sterilization, deodorization, etc., a plurality of synthetic resin layer (2) is bonded to the silver nano resin layer (1) to form a packaging film (100) The strength of the packaging film is increased by the tension acting between the layers bonded to each other, thereby increasing durability.
