친환경 보냉팩{ECO-FRIENDLY COOLING AND KEEPING PACK}Eco-friendly cold pack {ECO-FRIENDLY COOLING AND KEEPING PACK}

본 고안은 친환경 보냉팩에 관한 것으로, 특히 분리수거시 종이로 분류되어질 수 있으면서도 인쇄의 다양성은 물론 보냉포장시 발생되는 표면결로 발생을 방지토록 한 것이다.The present invention relates to an eco-friendly cold storage pack, and in particular, it is designed to prevent the occurrence of surface condensation that occurs during cold packaging as well as diversity of printing while being classified as paper during separate collection.

현재 일반적인 보냉팩은 비닐지로 이루어지는 다층의 적층구조로 이루어지고 특히 통상 표면은 이면인쇄가 가능한 PET필름과 상기 인쇄층이 잘보이도록 하면서 외부에서 조사되는 빛을 차단하기 위한 은박층과 상기 은박층의 이면에는 단열을 위한 발포시트층과 보냉팩에 수용되어 보관되는 내용물의 위생적인 부분과 보냉팩을 구현하기 위하여 파우치형태로 접착할 경우에 접착성을 제공하기 위하여 PE층으로 이루어지게 되는 것이다.Currently, a general cold storage pack is made of a multi-layered laminate structure made of vinyl paper, and in particular, a PET film capable of back printing on the surface, a silver foil layer for blocking light irradiated from the outside while making the printed layer visible, and the silver foil layer On the back side, it is made of a foam sheet layer for insulation and a PE layer to provide adhesiveness when attached in a pouch form to implement a sanitary part of the contents accommodated and stored in the cold pack and the cold pack.

그러나 이러한 비닐지로 사용되는 파우치 형태의 보냉팩의 사용은 최근에 친환경적이지 않다고 하여 사용을 제한하고 있는 점과 또한 분리수거시 상기와 같이 합지된 상태에서도 비닐지로 분류되어 폐기할 경우에 많은 불편함이 존재하게 되는 것이다.However, the use of the pouch-type cooling pack used in such plastic paper has recently been restricted because it is not eco-friendly, and there is a lot of inconvenience when it is classified as plastic paper and discarded even in the laminated state during separate collection. will come into existence

특히 이러한 파우치 형태의 보냉팩은 물품의 포장시에는 포장된 파우치 내부의 온도와 외부의 온도차이로 인하여 파우치 형태의 보냉팩의 표면으로 결로현상에 의하여 물기가 발생되면서 이러한 보냉팩을 가방등에 다른 물품과 동시에 휴대할 경우에 가방등에 수납되어진 다른 물품에 피해를 주게 되면서 휴대할 경우에 불편함을 야기토록 한다는 것이고, 이러한 물기로 인하여 이러한 보냉팩의 휴대시 불편함을 야기하게 되는 것이다.In particular, in the case of such a pouch-type cold storage pack, moisture is generated by dew condensation on the surface of the pouch-type cold storage pack due to the temperature difference between the inside temperature and the outside temperature of the packaged pouch, and the cold storage pack is placed on the bag, etc. When carrying at the same time, it causes damage to other items stored in a bag, etc., and causes inconvenience when carrying, and this moisture causes inconvenience when carrying such an insulated pack.

따라서 본 고안은 이러한 결로 발생의 문제점과 분리수거시의 문제점을 해소하기 위한 것이다.Therefore, the present invention is to solve the problem of the occurrence of dew condensation and the problem of separate collection.

이를 위하여 본 고안에서는 합지된 상태에서 내측으로부터 내용물의 보호와 발포시트층의 보호를 위한 PE층과 PE층의 상층으로는 단열을 위한 발포시트층과 상기 발포시트층의 상층으로는 발포시트층의 보호와 종이시트와의 접착을 위한 접착층을 구비토록 하고 상기 접착층의 상층으로는 종이시트를 합지토록 한 것이다.To this end, in the present invention, in the laminated state, a PE layer for protection of the contents and protection of the foam sheet layer from the inside, a foam sheet layer for insulation as an upper layer of the PE layer, and a foam sheet layer as an upper layer of the foam sheet layer An adhesive layer for protection and adhesion to the paper sheet is provided, and a paper sheet is laminated as an upper layer of the adhesive layer.

또한 상기 발포시트층의 상층으로 이면에 은박층이 구비되는 필름층을 접착층을 이용하여 합지토록 하고, 상기 필름층의 상층으로는 종이시트를 접착층을 사용하여 합지토록 하는 것이다. In addition, a film layer having a silver foil layer on the back surface as an upper layer of the foam sheet layer is laminated using an adhesive layer, and a paper sheet is laminated using an adhesive layer as an upper layer of the film layer.

따라서 종이시트에 의하여 인쇄의 우수성의 제공은 물론 분리수거시 종이로 분류되어 분리수거가 용이토록 될 수 있고 특히 종이시트로 인하여 보냉을 위한 물품의 포장시에도 결로현상이 외부로 발생되지 않게 되는 장점이 있는 것이다.Therefore, the paper sheet not only provides the superiority of printing, but it is also classified as paper and can be easily separated and collected during separate collection. there will be

이하 첨부도면에 의거 본 고안을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail based on the accompanying drawings.

도1은 본 고안의 제1실시예를 나타내는 것으로, 그 구성은 파우치형으로 보냉팩의 구현을 위하여 다층으로 합지된 상태로 이루어지고 그 층의 구조는 내측으로부터 순차적으로, 포장되는 내용물의 위생적인 보호와 그 상층에 위치되는 발포시트층(20)의 보호를 위한 PE층(10)과 상기 PE층(10)의 상층으로는 단열을 위하여 발포시트층(20)이 PE층(10)과 열에 의하여 합지토록 되고, 이때 발포시트층(20)은 반드시 동일한 재질인 PE로 발포성형되어진 것을 사용하게 되는 것이다.Figure 1 shows a first embodiment of the present invention, the configuration of which is made in a state of being laminated in multiple layers for the implementation of a pouch-type cold storage pack, and the structure of the layers is sequentially from the inside, hygienic of the packaged contents. The PE layer 10 for protection and protection of the foam sheet layer 20 positioned on the upper layer and the foam sheet layer 20 for thermal insulation as an upper layer of the PE layer 10 are the PE layer 10 and heat. The foam sheet layer 20 is necessarily foamed with PE, which is the same material, to be used.

또한 상기 발포시트층(20)의 상층으로는 발포시트층(20)의 보호와 종이시트(30)와의 접착을 위한 접착층(1)을 구비토록 하고 상기 접착층(1)의 상층으로는 종이시트(30)를 가 위치되어지는 것이다.In addition, as an upper layer of the foam sheet layer 20, an adhesive layer 1 for protection of the foam sheet layer 20 and adhesion to the paper sheet 30 is provided, and as an upper layer of the adhesive layer 1, a paper sheet ( 30) will be located.

이때 PE층(10)은 필름을 사용하여 발포시트층(20)과 열로 가압하여 합지할 수 있지만 합지시 PE층(10)을 구성하는 필름의 일측면과 대응되는 발포시트층을 열에 의하여 용융토록 해야 발포시트층(20)과 열접착이 가능하게 되는데 이때 이러한 PE층(10)을 구성하는 필름이나 발포시트층(20)의 일측면을 용융토록 한다는 것이 장소적인 조건과 기온적인 조건에 따라서 달라지게 되어 가공상의 어려움이 있어 제조원가가 상승되는 문제점이 있다.At this time, the PE layer 10 can be laminated by pressing the foam sheet layer 20 with heat using a film, but when laminating, the foam sheet layer corresponding to one side of the film constituting the PE layer 10 is melted by heat. Heat bonding with the foam sheet layer 20 is possible only when the film constituting the PE layer 10 or one side of the foam sheet layer 20 is melted depending on location and temperature conditions. There is a problem in that the manufacturing cost is increased due to the difficulty in processing.

따라서 본 고안에서는 제조원가의 절감은 물론 생산성의 향상을 위하여 PE층(10)을 발포시트층(20)에 티다이(T-Die)방식으로 가열하여 용융된 상태에서 코팅처리할 경우에는 저렴하면서 제조의 용이성을 제공할 수 있게 되는 것이다.Therefore, in the present invention, in order to reduce manufacturing cost as well as improve productivity, when the PE layer 10 is heated to the foam sheet layer 20 in a T-die method and coated in a molten state, it is manufactured at a low cost. It will be possible to provide the ease of

또한 상기 발포시트층(20)의 상층으로 종이시트(30)를 합지할 경우에는 종이시트(30)에 티다이(T-Die)방식으로 PE를 코팅하여 접착층(1)을 형성하면서 발포시트층(20)과 합지하게 되는 것이다.In addition, when the paper sheet 30 is laminated as the upper layer of the foam sheet layer 20, PE is coated on the paper sheet 30 in a T-Die method to form the adhesive layer 1 while forming the foam sheet layer. It will be combined with (20).

그러나, 종이시트와 발포시트층을 합지할 경우에 접착층(1)을 티다이(T-Die)방식으로 형성할 경우에는 통기가 가능하여 보냉을 위한 단열효과가 떨어지게 되는 문제점이 야기될 수 있어 접착층(1)의 두께를 일반적인 티 다이방식으로 코팅할 경우의 코팅두께보다는 좀더 두껍게 코팅토록 함으로서 단열효과를 증대토록 할 수 있는 것이다.However, in the case of laminating the paper sheet and the foam sheet layer, if the adhesive layer 1 is formed in a T-die method, ventilation is possible, which may cause a problem in that the insulation effect for cooling is deteriorated. It is possible to increase the insulation effect by coating the thickness of (1) thicker than the coating thickness in the case of general T-die coating.

그러나 가장 우수한 단열효과로는 도2에서 예시하는 바와 같이 제2실시예로 할 경우에 가장 우수함을 확인할 수 있었고 저렴한 제조가 가능토록 할 수 있는 것이다.However, as the most excellent thermal insulation effect, as illustrated in FIG. 2 , it was confirmed that the second embodiment was the most excellent, and it was possible to manufacture inexpensively.

상기 제2실시예에서의 보냉팩으로서의 파우치(100)의 적층구조는 다층으로 합지된 상태에서 내측으로부터 포장되는 내용물의 위생적인 보호와 발포시트층(20)의 보호를 위한 PE층(10)을 단열을 위한 발포시트층(20)에 제조원가의 절감은 물론 생산성의 향상을 위하여 티다이(T-Die)방식으로 코팅처리하고, 상기 발포시트층(20)의 상층으로는 이면에 은박층(41)이 구비되는 필름층(40)을 또 다른 접착층(2)을 이용하여 합지토록 하고, 상기 필름층(40)의 상층으로는 종이시트(30)를 접착층(1)을 사용하여 합지토록 하는 것이다.The laminated structure of the pouch 100 as a cold pack in the second embodiment is a PE layer 10 for hygienic protection of the contents packaged from the inside in a multi-layer laminated state and protection of the foam sheet layer 20. The foam sheet layer 20 for thermal insulation is coated with a T-die method to reduce manufacturing cost as well as improve productivity, and the upper layer of the foam sheet layer 20 is a silver foil layer 41 on the back side. ) is to be laminated using another adhesive layer (2), and a paper sheet (30) is laminated using an adhesive layer (1) as an upper layer of the film layer (40). .

이때 은박층(41)이 구비되는 필름층(40)은 내인장성이 우수한 PET 필름을 사용하는 것이 좋고, 은박층(41)은 은박호일을 합지할 수 있지만 원가가 상승되는 문제점으로 은박도포를 한 후 건조토록 하는 것이다.At this time, the film layer 40 provided with the silver foil layer 41 is preferably a PET film with excellent tensile resistance, and the silver foil layer 41 can be laminated with silver foil foil, but silver foil is applied due to the problem of increasing the cost. After that, let it dry.

그러나 상기 은박층(41)을 은박호일을 사용한 후 상기 은박호일의 상면에 접착층(1)을 티다이방식으로 코팅하면서 종이시트(30)를 합지토록 할 경우에도 내 인장성이 우수하면서 결로가 발생되지 않게 되는 것이다.However, even when the paper sheet 30 is laminated while coating the adhesive layer 1 on the upper surface of the silver foil by T-die method after using the silver foil for the silver foil layer 41, the tensile resistance is excellent and condensation occurs. it will not happen

또한 상기 PET필름으로 이루어지는 필름층(40)의 상층으로 합지되는 종이시트(30)는 접착층(1)을 상술한 바와 같이 티다이방식으로 코팅 한 후 종이시트(30)와 합지할 경우에 저렴하면서도 제조의 용이성을 제공하게 되는 것이다.In addition, the paper sheet 30 laminated as an upper layer of the film layer 40 made of the PET film is inexpensive when laminated with the paper sheet 30 after coating the adhesive layer 1 in the T-die method as described above. This will provide ease of manufacture.

또한 본 고안에서의 종이시트(30)는 일반적인 포장지나 습자지(노루지라고도함) 보다는 신장성이 우수한 크라프트지를 사용할 경우에 결로현상이 발생되지 않는 것이다.In addition, the paper sheet 30 in the present invention does not cause dew condensation when using kraft paper with superior extensibility than general wrapping paper or writing paper (also called noroji).

또한 크라프트지를 사용할 경우에 신장성에 의하여 접혀짐이 없이 합지의 용이성도 제공할 수 있게 되는 것이다.In addition, when using kraft paper, it will be possible to provide the ease of lamination without folding due to extensibility.
