Description

재활용이 가능한 리필팩Recyclable Refill Pack

본 발명은 사용후 회수하여 재활용할 수 있는 리필팩에 관한 것이다.The present invention relates to a refill pack that can be recovered and used after use.

최근 자원의 고갈과 쓰레기 증가에 의한 환경 오염으로 리필팩(Refill pack)이 많이 사용되고 있다.Recently, refill packs have been widely used due to depletion of resources and pollution due to increased waste.

리필팩은 예를 들면 화장품이나 샴푸 등의 경우 플라스틱 용기나 유리 용기에 담아서 사용하기 때문에 이들 용기들을 한 번 사용 후 버리게 되는 경우 귀중한 자원의 낭비를 가져오고 제품의 원가 부담을 가져올 뿐 아니라 쓰레기로 배출되는 경우 부피가 크고 썩지도 않아서 환경 오염을 유발하기 때문에 최근에는 비닐용기(리필팩)에 별도로 내용물을 담아서 판매하므로서 이들 용기를 버리지 않고 반복 사용할 수 있도록 하고 있다.For example, refill packs are used in plastic or glass containers in the case of cosmetics or shampoos. If these containers are thrown away after being used once, they are not only a waste of valuable resources but also a cost burden of the product and are discharged as garbage. If it is bulky and does not rot, causing environmental pollution, in recent years, by selling the contents in a plastic container (refill pack) separately, so that these containers can be used over and over again.

일반적으로 사용되는 종래 리필팩(20)의 구조를 도 3과 도 4에 도시하였다.3 and 4 illustrate the structure of a conventional refill pack 20 that is generally used.

종래 리필팩(20)은 바깥층에 폴리에스텔필름층(21,PET필름)이 위치하고 그의 안쪽으로 나일론 필름층(22)을 접착하고 안쪽에는 다시 LLDPE 필름층(23 : Low density poly ethylene)을 접착한 다층 접합 원지를 사용하여 용기의 테두리(24)를 형성하는 가장자리를 가열 압착처리하므로써 내측으로 상호 접하는 LLDPE필름층(23 )을 용착시켜 용기를 형성하고 있다.Conventional refill pack 20 is a polyester film layer (21, PET film) is located on the outer layer and the nylon film layer 22 is bonded to the inside thereof and the LLDPE film layer (23: low density poly ethylene) to the inside again The edge which forms the edge 24 of a container is heat-compression-processed using multilayer bonding paper, and the LLDPE film layer 23 which mutually contacts inward is welded, and the container is formed.

그런데 재료의 가격상 LLDPE가 가장 유리함에도 불구하고 상기와 같이 복잡하게 여러 가지 재질을 적층 접합시킨 원지필름을 사용하여 리필팩을 제조하는 이유는 LLDPE의 단일 재질을 사용할 경우 내면이 열 용착되기 위해서는 그의 외면에 융점보다 높은 온도로 압착하여야 하므로 LLDPE 필름 외표면이 열에 의해 변형되어지게 되므로써 품질 불량을 유발하고 또한 접착선이 끊어지는 문제점 및 LLDPE 자체는 강도가 약하여 내용물을 봉입시 봉투가 서있는 상태를 유지하는 힘이 부족하기 때문이다.However, although LLDPE is the most advantageous in terms of the price of materials, the reason for manufacturing a refill pack using a base film in which various materials are laminated and bonded as described above is that when a single material of LLDPE is used, the inner surface is heat-welded to Since the outer surface of the LLDPE film is deformed by heat because it must be pressed to a temperature higher than the melting point on the outer surface, it causes quality defects and breaks the adhesive line, and the strength of the LLDPE itself is weak so that the envelope remains standing when the contents are sealed. Because of lack of power.

이에따라 값은 비싸나 뻣뻣하여 형태 유지성이 좋고 또한 인쇄성이 좋은 폴리에스텔필름층(21)을 바깥으로 붙여 LLDPE재질의 단점을 보완하고 있으며, 이로써 열을 가하여 테두리 접착시 융점이 높은 폴리에스텔필름층(21)이 손상되지 아니하고 융점이 낮은 내측의 LLDPE필름층(23)만을 녹여 쉽게 접착할 수 있게 된 것이다.Accordingly, the value of the polyester film layer 21 is expensive and stiff to maintain the shape and the printability of the polyester film layer 21 to the outside to compensate for the disadvantages of the LLDPE material. 21) is not damaged and only the LLDPE film layer 23 of the inner melting point is easily melted to be able to adhere.

한편, 폴리에스텔이나 LLDPE재질은 인장 강도가 약하므로 강도를 보강 하기 위하여 사이에 얇은 나일론 필름층(22)을 개재시켜 적층하고 있다.On the other hand, polyester or LLDPE material has a weak tensile strength, and is laminated with a thin nylon film layer 22 therebetween to reinforce the strength.

또한 최근에는 폴리에스텔필름층(21)을 생략하고 두께를 키운 나일론 필름층(22)과 LLDPE 필름층(23)의 2중 구조로 적층된 것도 있으나 나일론이 폴리에스텔에 비하여 단가가 훨씬 비싸기 때문에 3중 구조에 비하여 가격상 불리하다.In addition, in recent years, the polyester film layer 21 is omitted, but the laminated structure of the thicker nylon film layer 22 and the LLDPE film layer 23 has been laminated in a double structure, but since the unit cost is much higher than that of polyester 3 It is disadvantageous in price compared with the heavy structure.

이와같이 서로 다른 재질의 적층 필름을 사용하게 된 이유는 폴리에스텔이나 나일론을 단독사용하게 될 경우 열 접착성이 나빠 봉투의 형성이 곤란하기 때문에 부득이 융착성이 좋은 LLDPE를 함께 사용할 수 밖에 없는데 기인한 것이며, LLDPE 재질의 단독 사용도 앞서 설명한 것과 같이 융착 과정에 품질 불량을 유발하는 문제점이 있기 때문에 어느 경우나 단일 재질의 사용은 곤란한 것으로서 당업계에 인식되어져 오고 있다.The reason why the laminated films of different materials are used is that the use of polyester or nylon alone results in poor thermal adhesion, which makes it difficult to form an envelope. As described above, the use of LLDPE material alone has a problem of causing quality defects in the welding process, and thus, the use of a single material has been recognized in the art as difficult.

그러나 상기와 같이 서로 다른 재질을 적층시켜 형성한 원지필름을 사용하여 리필팩을 제조하게 되므로써 한 번 사용된 리필팩은 재생이 불가능하여 쓰레기로 매립 처리되거나 소각 처리되면서 유독물질을 방출하여 환경오염을 유발하고 자원 낭비를 초래하게 되는 문제점이 있게 되어 환경보호상 등장하게 된 리필팩의 의미를 반감시키고 있다.However, since the refill pack is manufactured by using the original film formed by stacking different materials as described above, the refill pack once used cannot be recycled and is disposed of as trash or incinerated, thereby releasing toxic substances to prevent environmental pollution. There is a problem that causes a waste of resources and causes half the meaning of the refill pack appeared in the environmental protection.

본 발명은 상기와 같은 문제점을 감안하여 제안된 것으로서 그의 목적으로 하는 것은 사용후 회수하여 재활용 처리가 가능한 재질의 리필팩을 제공하는 데 있다.The present invention has been proposed in view of the above problems, and its object is to provide a refill pack of a material that can be recovered after use and recycled.

이하 본 발명의 구성과 작용에 대하여 설명한다.Hereinafter, the configuration and operation of the present invention will be described.

도 1은 본 발명에 의한 리필팩의 단면구조를 나타내는 도면으로 리필팩(1)의 원지는 2매의 필름이 적층된 2중 구조체로서 용기의 바깥에는 내열성의 외층필름(2 )이 위치하며 공간(3)내에 충진되는 내용물에 접하는 내측에는 저온 실링성의 내층필름(4)이 위치한다.1 is a view showing the cross-sectional structure of the refill pack according to the present invention. The base of the refill pack 1 is a double structure in which two films are stacked, and the outer layer of the heat-resistant outer film 2 is located outside the container. The inner-layer film 4 of low temperature sealing property is located in contact with the contents filled in (3).

상기 외층필름(2)과 내층필름(4)은 다같이 에틸렌 계통의 수지로서 그 성분 함량에 따라 양측 필름(2)(4)의 용융점이 다르다.The outer layer film 2 and the inner layer film 4 are all ethylene-based resins, and the melting points of both films 2 and 4 are different according to the component content thereof.

상기 외층필름(2)의 바깥면에는 미세한 엠보싱을 주어 인쇄가 용이하도록 코로나처리(5)가 되어 있다.The outer surface of the outer layer film 2 is corona treated (5) to give fine embossing to facilitate printing.

상기 외층필름(2)은 LLDPE(Low density poly ethylene, 융점 약 102℃) 23∼27%, HDPE(High density poly ethylene, 융점 약 126℃)70∼73%, 에틸렌계열 수지인 내열제 0.1∼0.3%, 색상을 내기 위한 유백색 마스타 뱃취 2∼4%의 성분으로 구성되며 융점은 대략 150℃ 이상을 나타내어 순수한 LLDPE보다 내열성이 높고 HDPE의 다량 함유로 강도도 높아져 형상 유지성이 좋아진다.The outer layer film 2 is LLDPE (low density poly ethylene, melting point of about 102 ℃) 23-27%, HDPE (High density poly ethylene, melting point of about 126 ℃) 70-73%, heat-resistant 0.1-0.3 ethylene-based resin It consists of 2 ~ 4% of milky master batch for color, and has a melting point of about 150 ℃ or more. It has higher heat resistance than pure LLDPE and high strength due to the large amount of HDPE, which improves shape retention.

상기 저온 실링성 내층필름(4)은 LLDPE 70∼76%, EVA(Ethylene vinyl acetate 융점 약 80℃) 22-28%, 색상을 내기 위한 유백색 마스타 뱃취 1∼3%의 성분으로 구성되며 EVA의 함유로 융점은 약 90℃로 낮다.The low-temperature sealing inner film 4 is composed of 70 to 76% LLDPE, 22-28% EVA (Ethylene vinyl acetate melting point about 80 ℃), milky master batch 1 to 3% to give a color and contains EVA The melting point is as low as about 90 ° C.

이와같은 본 발명은 리필팩(1, 봉투)을 제조하기 위하여 먼저 원지필름을 제조하게 되는 데 종래와 같이 2매의 필름을 접착제를 사용하여 접착시키는 것이 아니라 도 2에 도시하는 것과 같이 외층필름(2)을 구성하는 조성성분의 용융액을 일측호퍼(6)에 수용하고 격벽(7)으로 구획하는 타측호퍼(8)에는 내층필름(4)을 형성하는 조성성분의 용융액을 넣어 노즐(9)을 통해 방사하여 얇은 필름으로 뽑아낼 때 용액이 층류를 이루면서 유동하는 동안 굳게되면서 자연스럽게 경계부에서 융착되어져 한쪽은 내열성의 외층필름(2)을 형성하고 타측은 저온 실링성의 내층필름(4)을 형성하게 되는 것이다.In the present invention, to prepare a refill pack (1, an envelope), first, a paper film is prepared. Instead of bonding two films using an adhesive as in the related art, as shown in FIG. 2) The melt of the composition component forming the inner layer film 4 is placed in the other hopper 8 which receives the melt of the composition constituting the composition in one side hopper 6 and partitions it into the partition wall 7. When spun through and pulled out into a thin film, the solution hardens while flowing in a laminar flow, and is naturally fused at the boundary, so that one side forms a heat resistant outer layer film 2 and the other side forms a low temperature sealing inner layer film 4. will be.

이와같이 하여 적층 처리된 원지필름(10)을 내층필름(4)끼리 접하도록 포개어 놓은 상태에서 용기를 형성토록 테두리를 따라 열압착기구등으로 열을 가하여 눌러 붙이면 접착경계면(11)이 형성되어지게 되는 것이다.In this way, the laminated film 11 is stacked so that the inner layer films 4 are in contact with each other, and the adhesive boundary surface 11 is formed by applying heat and pressing with a thermocompression mechanism along the edge to form a container. will be.

[실시예]EXAMPLE

LLDPE 25%, HDPE 71.8%, 내열제 0.2%, 마스타뱃취 3%를 혼합한 용액과 LLDPE 73%, EVA 25%, 마스타뱃취 2%를 혼합한 용액을 각각 호퍼(6)(8)에 넣고 공유 노즐(9)을 통하여 일측면은 융점 152℃이고 타측면은 융점이 93℃인 원지필름(10)을 얻었다. 이때 원지필름(10)의 외층필름(2)의 두께는 95μm이고 내층필름(4)의 두께는 75μm이 되도록 적층 두께를 설정하였으며 이를 이용하여 도 3에 도시하는 것과 같이 밑면이 원형을 이루는 형태의 리필팩(1)을 제조하였다.A mixture of 25% LLDPE, 71.8% HDPE, 0.2% heat resistant, and 3% master batch, and a solution containing 73% LLDPE, 25% EVA and 2% master batch were placed in a hopper (6) (8), respectively. Through the nozzles 9, a base film 10 having a melting point of 152 ° C and a melting point of 93 ° C on the other side thereof was obtained. At this time, the thickness of the outer layer film 2 of the base film 10 is set to a thickness of 95μm and the thickness of the inner layer film 4 is 75μm and by using this as shown in FIG. Refill pack (1) was prepared.

이때 내층필름(4)을 열 용착시키기 위하여 95℃의 실링바(통상적 가열 접착 기구로 도시 생략)를 이용하여 테두리(12)를 압착하였으며 실링바의 열은 외층필름(2)을 타고 내층필름(4)에 전하여져 내층필름(4)이 서로 융착되었으며, 외층필름(2)은 열에 의해 쭈글쭈글하게 변형되는 현상이 전혀 관찰되지 아니하고 매끈하게 처리되었다.At this time, in order to heat-weld the inner film 4, the edge 12 was pressed using a 95 ° C. sealing bar (not shown as a general heat-adhesive device), and the heat of the sealing bar was taken by the inner film (2). 4, the inner layer films 4 were fused to each other, and the outer layer film 2 was smoothly processed without any phenomenon of zigzag deformation due to heat.

리필팩의 전체 용량은 800㎖, 1100㎖, 1500㎖, 2500㎖ 네종류로 만들었으며 각기 650㎖, 900㎖, 1300㎖, 2200㎖의 샴푸액을 충진하였다. 내용물을 충진한 상태에서 리필팩 용기의 원형 바닥을 지면에 위치시켜 세워놓았다.The total volume of the refill pack was made into four types of 800ml, 1100ml, 1500ml and 2500ml and filled with 650ml, 900ml, 1300ml and 2200ml, respectively. With the contents filled, the circular bottom of the refill pack container was placed upright on the ground.

이때 800㎖, 1100㎖, 1500㎖의 세 용기는 정상적으로 서 있는 상태를 유지하였으나 2500㎖의 용기는 내용물의 하중을 이기지 못하고 무너졌다.At this time, three vessels of 800 ml, 1100 ml, and 1500 ml remained in a normal standing state, but the vessel of 2500 ml failed to overcome the load of the contents.

이와같은 사실로 미루어 형태 유지성이 우수한 즉 뻣뻣한 성질이 강한 폴리에스텔이나 나일론 필름을 사용할 때 보다는 강도가 약하여 많은 내용물을 담는데에는 다소 문제가 있으나 2000㎖ 이하의 소용량의 내용물을 담는데는 무리가 없음을 확인할 수 있다.This fact suggests that the strength is weaker than the case of using polyester or nylon film having excellent shape retention, that is, the stiffness property, and thus it is somewhat problematic to contain a lot of contents, but there is no problem in storing small contents of less than 2000ml. Can be.

다음에 종래의 리필팩과 본원 발명의 리필팩의 물성을 시험한 결과를 표 1에 나타내었다.Next, Table 1 shows the results of testing the physical properties of the conventional refill pack and the refill pack of the present invention.

Figure kpo00001

이상과 같은 본 발명의 리필팩은 외층은 융점이 높아 열에 강한 에틸렌 계열의 수지를 사용하고 내층은 융점이 낮은 동일 계열의 수지를 사용하되 제조 과정에서 내외층이 용착되어 하나의 원지필름을 형성한 것을 이용하여 제작되므로써 인쇄가 행하여지는 외층필름 표면의 열변형이 없이 내층필름을 손쉽게 열부착시키는 것이 가능하여 봉투 제작이 쉽고 값싼 재료의 사용으로 원가 절감이 가능하다.As described above, the refill pack of the present invention uses an ethylene-based resin resistant to heat due to its high melting point and an inner layer using the same series of resin having a low melting point, but the inner and outer layers are welded in the manufacturing process to form one base film. Since the inner layer film can be easily heat-bonded without thermal deformation of the outer layer film to be printed by using the material, it is easy to manufacture an envelope and the cost can be reduced by using cheap materials.

그러나 무엇보다 같은 계통의 재질만을 사용하게 되므로써 한 번 사용후 쓰레기 처리하지 아니하고 회수하여 다시 리필팩 제조의 원료나 타제품 제조의 원료로 사용할 수 있어 재활용이 가능하여 자원의 낭비를 막고 환경 오염을 방지하는 효과가 있게 된다.Most of all, however, only the materials of the same system are used, so they can be recovered and used again as raw materials for refill packs or other products for recycling without waste disposal, and can be recycled to prevent waste and prevent environmental pollution. It will work.
