Description

보온보냉파우치{COOLING AND KEEPING WARM POUCH}Thermal insulation pouch {COOLING AND KEEPING WARM POUCH}

본 발명은 보온보냉파우치에 관한 것으로, 특히 분리수거시 종이로 분류되어질 수 있으면서도 인쇄의 다양성은 물론 보냉시 발생되는 결로 등을 방지할 수 있도록 한 것이다.The present invention relates to a thermal insulation pouch, and in particular, it is possible to prevent condensation generated during cold storage as well as diversity of printing while being classified as paper during separate collection.

현재 보온보냉파우치는 비닐지로 이루어지는 다층의 적층구조로 이루어지고 특히 표면은 이면인쇄가 가능한 PET필름과 상기 인쇄층이 잘보이도록 하면서 외부에서 조사되는 빛을 차단하기 위한 은박층과 은박층의 이면에는 단열을 위한 발포시트층과 파우치에 보관되는 내용물의 위생적인 부분과 파우치로서의 구현을 위한 접착성등을 위하여 PE층으로 이루어지게 되는 것이다.Currently, the thermal insulation pouch is made of a multi-layered laminated structure made of vinyl paper, and in particular, the surface is a PET film that can be printed on the back side, and the silver foil layer and the back side of the silver foil layer to block light from outside while making the printing layer visible. It is made of a foam sheet layer for insulation and a PE layer for hygienic parts of the contents stored in the pouch and adhesion for realization as a pouch.

그러나 이러한 파우치의 단점은 친환경적인 부분을 구려하여 현재 포장재로서 비닐지의 사용을 제한하고 있는 점과 또한 분리수거시 비닐지로 분류되어 폐기할 경우에 많은 불편함이 존재하게 되는 것이다.However, the disadvantages of these pouches are that the use of vinyl paper as a packaging material is currently restricted in consideration of eco-friendly parts, and there is a lot of inconvenience when it is classified as plastic paper and disposed of during separate collection.

특히 보냉을 위한 물품의 포장시에는 포장된 파우치 내부의 온도와 외부의 온도차이로 인하여 파우치의 표면으로 결로현상에 의하여 물기가 발생되면서 이러한 포장상태로 가방등에 휴대할 경우에 가방등에 수납되어진 또 다른 물건에 피해를 주게 되면서 휴대할 경우에 불편함을 야기토록 한다는 것이고, 이러한 물기로 인하여 휴대시 불편함을 야기하게 되는 것이다.In particular, when packing items for cold insulation, moisture is generated by condensation on the surface of the pouch due to the difference between the temperature inside the packaged pouch and the outside temperature. It damages the object and causes discomfort when carrying it, and this moisture causes discomfort when carrying it.

따라서 본 발명은 이러한 문제점을 해소하기 위한 것이다.Therefore, the present invention is to solve this problem.

이를 위하여 본 발명에서는 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, and a foam sheet layer for insulation as an upper layer of the foam sheet layer, and a foam sheet layer as an upper layer of the foam sheet layer. An adhesive layer for protection and adhesion to a 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, as the upper layer of the foam sheet layer, a film layer having a silver foil layer on the back surface is laminated using an adhesive layer, and a paper sheet is laminated using an adhesive layer as the 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 also can be classified as paper during separate collection to facilitate separate collection. In particular, because of the paper sheet, condensation does not occur outside even when packaging for cold storage. There is this.

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

도1에 도시된 바와 같이 본 발명의 구성은 제1실시예로서 파우치로서의 구현을 위하여 다층으로 합지된 상태에서 내측으로부터 포장되는 내용물의 위생적인 보호와 발포시트층의 보호를 위한 PE층(10)과 상기 PE층의 상층으로는 단열을 위한 발포시트층(20)이 PE층과 열에 의하여 합지토록 되고, 이때 발포시트층(20)도 PE로 발포성형되어진 것을 사용하게 되는 것이다.As shown in Fig. 1, the configuration of the present invention is a first embodiment, a PE layer 10 for hygienic protection of the contents packaged from the inside and protection of the foam sheet layer in a state of being laminated in multiple layers for implementation as a pouch. And as the upper layer of the PE layer, the foam sheet layer 20 for insulation is laminated by heat with the PE layer, and at this time, the foam sheet layer 20 is also foam-molded of PE.

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 합지토록 한 것이다.In addition, the upper layer of the foam sheet layer 20 is provided with an adhesive layer 1 for protecting the foam sheet layer 20 and for adhesion to the paper sheet 30, and the upper layer of the adhesive layer 1 is a paper sheet ( 30).

이때 PE층(10)은 필름을 사용하여 발포시트층(20)과 합지할 수 있지만 합지시 PE층(10)을 구성하는 필름의 일측면을 열에 의하여 용융토록 해야 발포시트층(20)과 열접착이 가능하게 되는데 이때 이러한 PE층(10)을 구성하는 필름의 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 with the foam sheet layer 20 using a film, but when laminating, one side of the film constituting the PE layer 10 must be melted by heat. Bonding is possible. At this time, melting one side of the film constituting the PE layer 10 varies according to local conditions and temperature conditions, and there is a problem in that manufacturing cost increases due to difficulty in processing.

따라서 제조원가의 절감은 물론 생산성의 향상을 위하여 PE층(10)을 발포시트층(20)에 티다이(T_Die)방식으로 코팅처리할 경우에는 저렴하면서 제조의 용이성을 제공할 수 있게 되는 것이다.Therefore, in the case of coating the PE layer 10 on the foam sheet layer 20 in a T_Die method in order to reduce manufacturing cost and improve productivity, it is possible to provide ease of manufacture while being inexpensive.

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 합지하거나, PE필름형태의 접착층(1)을 이용하여 종이시트(30)와 발포시트층(20)을 합지할 수 있는 것이다.In addition, in the case of laminating the paper sheet 30 as the upper layer of the foam sheet layer 20, the foam sheet layer is formed by coating PE on the paper sheet 30 in a T-Die method to form an adhesive layer (1). The paper sheet 30 and the foam sheet layer 20 can be laminated together with (20) or by using the adhesive layer (1) in the form of a PE film.

그러나, 접착층(1)을 티다이(T-Die)방식으로 형성할 경에는 통기가 가능하여 단열효과가 떨어지게 되는 문제점이 야기될 수 있어 접착층(1)의 두께를 좀더 두껍게 코팅토록 함으로서 단열효과를 증대토록 할 수 있는 것이다.However, when the adhesive layer 1 is formed in a T-Die method, ventilation may be possible, resulting in a problem that the thermal insulation effect is deteriorated. Therefore, the insulation effect is achieved by making the adhesive layer 1 more thickly coated. It can be increased.

그러나 가장 우수한 단열효과로는 도2에서 예시하는 바와 같이 또 다른 실시예로 할 경우에 가장 우수함을 확인할 수 있었고 저렴한 제조가 가능토록 할 수 있는 것이다.However, as illustrated in FIG. 2, as the most excellent heat insulation effect, it was possible to confirm the best in the case of another embodiment and to enable inexpensive manufacturing.

상기 제2실시예에서와 같이 파우치(100)로서의 구현을 위하여 다층으로 합지된 상태에서 내측으로부터 포장되는 내용물의 위생적인 보호와 발포시트층의 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.As in the second embodiment, a foam sheet for insulating the PE layer 10 for hygienic protection of the contents packaged from the inside and for the protection of the foam sheet layer in a multi-layer laminated state for implementation as a pouch 100 The layer 20 is coated with a T-Die method to reduce manufacturing cost as well as improve productivity, and a film layer provided with a silver foil layer 41 on the back surface as an upper layer of the foam sheet layer 20 ( 40) is laminated using another adhesive layer 2, and a paper sheet 30 is laminated using the adhesive layer 1 as an upper layer of the film layer 40.

이때 은박층이 구비되는 필름층(40)은 내인장성이 우수한 PET 필름을 사용하는 것이 좋고, 은박층은 은박호일을 합지할 수 있지만 원가가 상승되는 문제점으로 은박도포를 한 후 건조토록 하는 것이다.At this time, it is preferable to use a PET film having excellent tensile resistance for the film layer 40 provided with the silver foil layer, and the silver foil layer can be laminated with silver foil, but as a problem of increasing the cost, the silver foil is applied and then dried.

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 silver foil layer 41 is laminated with the paper sheet 30 while coating the adhesive layer 1 on the upper surface of the silver foil foil by a T-die method, condensation occurs while excellent tensile resistance. It will not work.

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 the adhesive layer 1 is coated by a T-die method as described above. It is to provide ease of manufacture.

또한 본 발명에서의 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 condensation when using kraft paper having excellent stretchability than general wrapping paper or wet paper (also referred to as noruji).

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