Description

직선형 절취특성을 갖는 파우치 및 제조방법 그리고 그 파우치 제조장치{POUCH HAVING THE LINETYPE CUTING FEATURE AND MANUFACTURING METHOD AND POUCH MANUFACTURING DEVICE}Pouch with manufacturing method and manufacturing method of the pouch having a straight cut feature {POUCH HAVING THE LINETYPE CUTING FEATURE AND MANUFACTURING METHOD AND POUCH MANUFACTURING DEVICE}

본 발명은 습기나 산소로부터 장기적인 보존성이 요구되는 내용물 포장을 위한 파우치에 관한 것으로, 상세하게는 항상 규정된 직선형 절취라인을 따라 매끄러운 절취가 이루어질 수 있도록 절취라인를 형성한 직선형 절취특성을 갖는 파우치 및 제조방법 그리고 그 파우치 제조장치에 관한 것이다.
The present invention relates to a pouch for packaging the contents requiring long-term preservation from moisture or oxygen, and in particular, a pouch having a straight line cutting property and a straight line cutting property to form a smooth cutting line along a prescribed straight line cutting line. Method and a pouch manufacturing apparatus.

포장의 가장 중요한 목적은 내용물 보호와 보존이다. 특히, 습기나 산소에 의해 보존성이 좌우되는 제품에 대해서는 수증기 및 가스 배리어성이 우수한 포장 재료를 사용하고, 용기를 밀봉, 봉합하기 위해 확실한 씰을 할 필요가 있다. The primary purpose of packaging is to protect and preserve the contents. In particular, for products whose storage properties are influenced by moisture and oxygen, it is necessary to use a packaging material which is excellent in water vapor and gas barrier properties, and to ensure a reliable seal to seal and seal the container.

하지만 보호기능과 함께 내용물을 꺼낼 때의 간편성, 즉 개봉 용이성(Easy opening)도 매우 중요한 포장의 기능이며, 이 밀봉성과 개봉성의 상반하는 두 가지 요소를 양립시켜야 비로서 우수한 포장이라 할 수 있다.However, in addition to the protection function, the simplicity of taking out the contents, that is, easy opening, is also a very important function of the packaging.

플라스틱 필름을 주체로 한 라미네이트 포장재를 이용한 식품/의약품용 파우치나 필로우파우치, 또는 스틱 포장 파우치 등의 히트씰 연포장 파우치는 상품이 필요한 여러 가지 포장 기능을 발휘할 수 있어서 포장분야에서 널리 이용되고 있다. Heat seal soft packaging pouches such as food / pharmaceutical pouches, pillow pouches, or stick packaging pouches using laminate packaging mainly composed of plastic films are widely used in the packaging field because they can exhibit various packaging functions required for a product.

라미네이트 필름은 기본적으로 베이스 필름, 배리어층 및 실란트 필름으로 구성되고, 포장공정에 따라서 제대, 충진 봉합되지만 일반적으로 제대 및 봉합은 히트씰로 행해진다.The laminate film is basically composed of a base film, a barrier layer and a sealant film, and is umbilized and filled sealed according to the packaging process, but in general, the umbilical film and the sealing are performed by heat seals.

히트씰 연포장 파우치의 밀봉에는 전술한 것과 같이 내용물의 보호가 충분히 유지될 수 있도록 균일하고, 확실한 씰이 필요하지만, 자칫하면 내용물을 꺼낼 때 톱 씰을 간단히 벗겨내기 어려운 경향이 있다. 이 때문에 대부분의 연포장 파우치에서는 개구수단으로써 이지커트(Easy cut) 기능이 필요하다.The sealing of the heat seal soft packaging pouch requires a uniform and reliable seal so that the protection of the contents can be sufficiently maintained as described above, but it tends to be difficult to simply peel off the top seal when taking out the contents. For this reason, an easy cut function is required as an opening means in most soft packaging pouches.

히트씰 연포장 파우치의 개봉 용이 수단으로써 일반적으로 행해지는 것은 개구 위치에 찢김 개시점(notch)을 나타내는 칼자국을 넣는 방법이다. 이처럼 찢김 개시점 즉, 노치를 형성하면 노치로 인해 커트의 개시는 용이하지만, 파우치를 구성하는 기재 즉, 필름의 특성에 따라 인열 방향(찢겨지는 방향)이 불규칙한 경우라면, 커트성이 나쁘고 방향성도 불규칙하여 매끄럽지 못한 패턴으로 찢겨져 버리는 문제가 있다.What is generally done as an easy opening means of a heat seal soft packaging pouch is a method of inserting a cut indicative of a tear start point (notch) at an opening position. When the tear initiation point, that is, the notch is formed, the cut is easy to start due to the notch. There is a problem of being torn into irregular and unsatisfactory patterns.

이에 대한 개선책으로, 레이져 가공을 통해 절취선(切取線)을 따라 미세한 구멍을 일정한 간격으로 내어 개봉 시 절취부위가 매끄럽고 반듯하게 절취될 수 있도록 한 방법도 이용되고는 있으나, 이 경우 천공된 구멍들로 인하여 작은 충격이나 눌림과 같은 조그만 외압에도 파우치가 쉽게 터질 수 있어서, 일회용 커피, 조미료와 같이 분말제품을 포장하는 소형 파우치에 국한되어 주로 사용되고 있는 실정이다.
As a remedy for this, a method of cutting a hole at a predetermined interval along the cutting line through laser processing to cut the cutting part smoothly and smoothly when opening is used, but in this case, due to the perforated holes Pouches can easily be broken even in small external pressures such as small impacts and squeezing, and are used mainly for small pouches for packing powder products such as disposable coffee and seasonings.

본 발명이 해결하고자 하는 기술적 과제는, 파우치를 구성하는 기재 즉, 필름의 특성에 따라 인열 방향이 불규칙한 경우라도 용이한 커트성을 보장할 수 있는 직선형 절취특성을 갖는 파우치 및 제조방법 그리고 그 파우치 제조장치를 제공하는 데에 있다.The technical problem to be solved by the present invention is a pouch and manufacturing method having a straight cut property that can ensure easy cutability even when the tear direction is irregular according to the characteristics of the substrate, that is, the film constituting the pouch, and the pouch manufacture It is to provide a device.

본 발명이 해결하고자 하는 다른 기술적 과제는, 커트가 시작되는 시점에서의 힘이 방향성이 지정된 방향으로부터 어긋나게 작용하더라도 절취에 있어서는 항상 규정된 직선형 절취라인을 따라 매끄러운 절취가 이루어질 수 있는 파우치 및 제조방법 그리고 그 파우치 제조장치를 제공하는 데에 있다.
Another technical problem to be solved by the present invention is a pouch and a manufacturing method which can be smoothly cut along a defined straight cutting line even when the force at the point of the cut starts to act out of the direction specified. The present invention provides a pouch manufacturing apparatus.

상기한 과제를 해결하기 위한 기술적인 수단으로서 본 발명은, 습기나 산소로부터 장기적인 보존성이 요구되는 내용물 포장을 위한 포장재로서, 전면시트와 후면시트 2매의 합성수지시트를 기반으로 하며, 개구 위치에 찢김 개시점을 나타내는 노치를 갖고, 노치로부터 개구 위치를 따라 직선상으로 연속되는 다수의 절취홈이 일정한 간격으로 이격형성된 절취라인을 갖는 직선형 절취특성을 갖는 파우치를 제공한다.As a technical means for solving the above problems, the present invention is a packaging material for packaging contents requiring long-term preservation from moisture or oxygen, based on a synthetic resin sheet of the front sheet and the back sheet of two sheets, tearing in the opening position Provided is a pouch having a notch indicative of a starting point, and having a straight cut feature, with a plurality of cutout grooves extending straight along the opening position from the notch, with cutout lines spaced at regular intervals.

여기서 상기 전면시트 및 후면시트는, 보강층과 열접착수지층으로 이루어진 기재필름 상에 표면보호층이 적층형성된 구성을 갖고, 상기 절취홈은 표면보호층과 접합하는 방향의 기재필름 일면에 형성되는 것을 특징으로 한다.Here, the front sheet and the rear sheet, the surface protective layer is laminated on the base film consisting of a reinforcing layer and a heat-adhesive resin layer, the cut groove is formed on one surface of the base film in the direction of bonding with the surface protective layer It features.

도 1 내지 도 3을 참조하여 본 발명의 실시예에 따른 파우치에 대해 먼저 살펴보면, 상기 파우치는 습기나 산소로부터 장기적인 보존성이 요구되는 내용물 포장을 위한 포장재로서, 전면시트와 후면시트 2매의 합성수지시트를 기반으로 하며, 개구 위치에 찢김 개시점을 나타내는 노치(5)를 갖고, 이 노치(5)로부터 개구 위치를 따라 직선상으로 연속되는 다수의 절취홈(40)이 일정한 간격으로 이격되어 형성된 절취라인(4)을 갖는 구성으로 이루어진다.Looking at the pouch according to an embodiment of the present invention with reference to Figures 1 to 3, the pouch is a packaging material for the contents packaging that requires long-term storage from moisture or oxygen, the front sheet and the back sheet two sheets of synthetic resin sheet A cutout formed in the opening position, having a notch 5 indicating a tear start point at the opening position, wherein a plurality of cutting grooves 40 continuous in a straight line along the opening position are spaced at regular intervals from the notch 5. It consists of a configuration having a line (4).

본 발명에서 상기 전면시트 및 후면시트는, 보강층(20)과 열접착수지층(30)으로 이루어진 기재필름(25) 상에 표면보호층(10)이 적층형성된 구성을 가지며, 표면보호층(10), 보강층(20), 열접착수지층(30)은 접착제 도포를 통한 라미네이팅(Laminating)을 통해 그 사이에 접착층이 존재하는 형태로 상호 접착이 이루어진다.In the present invention, the front sheet and the rear sheet has a configuration in which the surface protective layer 10 is laminated on the base film 25 including the reinforcing layer 20 and the heat adhesive resin layer 30, and the surface protective layer 10. ), The reinforcing layer 20 and the heat-adhesive resin layer 30 are mutually bonded in the form of an adhesive layer therebetween through laminating through the application of adhesive.

상기 표면보호층(10)은 수분침투나 산소투과와 같은 것으로부터 내용물을 보호하기 위한 배리어(Barrier)기능을 수행하며, 상기 열접착수지층(30)은 포장 내용물의 위생성 확보를 위한 것이다. 그리고 상기 보강층(20)은 파우치가 포장재로서 역할을 수행함에 있어서의 파단강성 확보 및 내열성, 내한성 등의 특성을 부여하며, 특히 파우치의 찢김이 개시된 시점에서의 용이한 커트성을 부여한다.The surface protective layer 10 performs a barrier function to protect the contents from moisture penetration and oxygen permeation, and the thermal adhesive resin layer 30 is for ensuring hygiene of the package contents. In addition, the reinforcing layer 20 imparts characteristics such as securing fracture strength and heat resistance and cold resistance when the pouch serves as a packaging material, and particularly, provides easy cutability at the time when the pouch is torn.

상기 표면보호층(10)으로는 포장(Packaging)과 증착(Metallizing)에 적합한 투명성, 내열성, 고장력, 뛰어난 치수안정성, 비투과성, 내습성, 내수성, 내화학성이 우수한 폴리에스터 필름(PET FILM 'PET 필름'이라 한다)이 적합하며, 열접착수지층(30)은 두께가 균일하며 매우 위생적인 필름으로 식품포장 등 유연포장의 소재로서 폭넓게 이용되는 무연신 필름 또는 폴리에틸렌 필름(PE film)이 소재로 이용될 수 있다.The surface protective layer 10 is a polyester film (PET FILM 'PET) having excellent transparency, heat resistance, high tensile strength, excellent dimensional stability, impermeability, moisture resistance, water resistance, and chemical resistance suitable for packaging and metallization. Film is suitable), and the heat-adhesive resin layer 30 is a uniform and very hygienic film, which is a non-stretched film or polyethylene film (PE film) widely used as a material for flexible packaging such as food packaging. Can be used.

상기 보강층(20)은 도 2의 실시예와 같이 내열 및 내한성 및 파대강도가 우수하면서 파우치를 개봉함에 있어 찢김 방향성 및 용이한 커트성을 부여하기에 적합한 나일론을 단독으로 한 소재 또는, 도 3의 다른 실시예에서와 같이 나일론(Nylon) 표면에 알루미늄 박판이 증착된 합성필름이 소재로 이용될 수 있다. The reinforcing layer 20 is a material made of nylon alone or suitable for providing tear direction and easy cutability in opening the pouch while excellent in heat resistance, cold resistance, and breaking strength, as in the embodiment of FIG. As in other embodiments, a synthetic film having aluminum thin films deposited on a nylon surface may be used as a material.

상기한 소재를 주체로 한 전, 후면 시트에 절취홈(40)을 형성시킴에 있어 상기 절취홈(40)은, 보강층(20)을 형성하는 나일론 필름 또는 나일론 합성필름에 열접착수지층(30)을 형성하는 무연신 필름이 접합되어 이루어진 기재필름(25)에 형성시키는 것이 바람직하다. 구체적으로는, 표면보호층(10)과 접속하는 방향에 위치한 기재필름(20)의 보강층(20) 일면에 형성시키는 것이 좋다.In forming the cutting grooves 40 in the front and rear sheets mainly composed of the above-mentioned materials, the cutting grooves 40 may be formed of a heat-adhesive resin layer 30 on a nylon film or a nylon composite film forming the reinforcing layer 20. It is preferable to form in the base film 25 which the unstretched film which forms () is joined. Specifically, it is good to form on one surface of the reinforcing layer 20 of the base film 20 located in the direction connecting with the surface protection layer 10.

표면보호층(10), 보강층(20), 열접착수지층(30)을 접합시켜 시트를 완성시킨 상태에서 절취홈(40)을 성형하는 것과 같이 표면가공을 수행하면, 상기 표면보호층(10)을 구성하는 PET 필름의 막이 손상될 수 있기 때문이다.If the surface protection layer 10, the reinforcing layer 20, the heat-adhesive resin layer 30 is bonded to the surface protective layer 10 by forming the cut groove 40 in the state of completing the sheet, the surface protection layer 10 This is because the film of the PET film composing the) may be damaged.

다시 말해, PET 필름의 경우 실리카(SILICA), 알루미나(ALUMINA)를 필름에 증착시켜 수분 및 산소투과를 억제시킴으로써 내용물(주로, 식품 또는 의약품)을 장기 보존할 수 있게 한 것이어서, 절취홈(40)을 성형하는 것과 같은 장력/충격 등의 외압을 받게 되면, 실리카(SILICA)와 알루미나(ALUMINA)에 의한 증착층의 막이 손상되며, 결과적으로는 내수성, 차단성이 떨어져 포장재로서 기능을 잃게 된다.In other words, in the case of PET film, silica (SILICA) and alumina (ALUMINA) are deposited on the film to inhibit moisture and oxygen permeation so that the contents (mainly food or medicine) can be stored for a long time, thus cutting groove 40 When an external pressure such as tension / shock such as molding is applied, the film of the deposition layer by silica (SILICA) and alumina (ALUMINA) is damaged, and as a result, water resistance and barrier property are lost, and the function as a packaging material is lost.

위와 같은 이유로서 상기 기재필름(25)에 절취홈(40)을 형성함에 있어서도, 상기 절취홈(40)은 적어도 2개 이상이 상하방향으로 일정한 간격으로 형성되도록 하는 것이 바람직하다. 이는 절취 과정 중 파우치를 찢는 힘의 방향성이 일정치 않아 최초 찢김이 개시된 절취홈(40)으로부터 다소 벗어나더라도 인접해 있는 다른 절취홈(40)에 의해서 직선에 가까운 절취패턴을 유지할 수 있도록 하기 위함이며, 이를 위한 절취홈(40)의 간격은 0.1mm ~ 2mm 정도가 적당하다.Even when forming the cutout groove 40 in the base film 25 for the same reason, it is preferable that at least two cutout grooves 40 are formed at regular intervals in the vertical direction. This is because the direction of the tearing force of the pouch during the cutting process is not constant, so that even if the first tear is slightly deviated from the starting cutting groove 40, the cutting pattern close to the straight line can be maintained by another adjacent cutting groove 40. , The interval of the cutting groove 40 for this is suitable about 0.1mm ~ 2mm.

상기한 본 발명의 파우치에 의하면, 파우치의 개구 위치를 따라 직선상으로 연속되는 다수의 절취홈(40)이 일정한 간격으로 이격형성되어 절취라인(4)을 형성함으로써, 파우치를 구성하는 기재 즉, 필름의 특성에 따라 인열 방향이 불규칙한 경우라도 용이한 커트성이 보장되고, 커트가 시작되는 시점에서의 힘이 방향성이 지정된 방향으로부터 어긋나게 작용하더라도 절취에 있어서는 도 4에 도시한 바와 같이 항상 규정된 직선형 절취라인(4)을 따라 매끄러운 절취가 이루어질 수 있다.
According to the pouch of the present invention, a plurality of cutting grooves 40 continuous in a straight line along the opening position of the pouch are formed at regular intervals to form a cutting line 4, that is, the substrate constituting the pouch, According to the characteristics of the film, even if the tear direction is irregular, easy cutability is ensured, and even if the force at the point of starting the cut acts out of the specified direction, the cut is always defined as shown in FIG. Smooth cutting along the cutting line 4 can be achieved.

다음은 상기한 구성으로 이루어진 본 발명의 실시예에 따른 파우치 제조방법에 대해 설명하기로 한다.Next, a pouch manufacturing method according to an embodiment of the present invention having the above configuration will be described.

상기 파우치를 제조하기 위한 과정은 도 5에 도시한 바와 같이, 기재필름 제작, 표면보호층에 접착제 도포 및 건조, 절취홈 가공, 기재필름과 표면보호층 접합, 대면적 시트 씰링 및, 씰링 처리된 대면적 시트 재단 및 노치 형성 등 크게, 6 단계로 구성된 공정으로 구성된다.The process for manufacturing the pouch, as shown in Figure 5, manufacturing the base film, applying and drying the adhesive on the surface protective layer, cut groove processing, bonding the base film and the surface protective layer, sealing a large area sheet, and the sealing treatment It consists of a six-step process, such as large area sheet cutting and notch formation.

단계별로는 먼저, 보강층(20)과 열접착수지층(30)을 접합시켜 기재필름(25)을 제작하는 단계로서, 상기 보강층(20)으로는 앞서 설명한 바와 같이 내열 및 내한성이 우수하면서 파우치를 개봉함에 있어 찢김 방향성 및 용이한 커트성을 부여하기에 적합한 나일론을 단독으로 한 소재 또는, 나일론 표면에 알루미늄 박판이 증착된 합성필름이 소재로 이용되며, 열접착수지층(30)으로는 유연포장의 소재로서 폭넓게 이용되며 매우 위생적인 무연신 또는 폴리에틸렌 필름을 소재로 한다.Step by step, first, the step of manufacturing the base film 25 by bonding the reinforcing layer 20 and the heat-adhesive resin layer 30, the reinforcing layer 20 as described above, while having excellent heat resistance and cold resistance as described above In opening, a material made of nylon alone or a synthetic film in which aluminum thin films are deposited on the surface of nylon is used as a material, and the heat-sealing resin layer 30 is a flexible packaging material. It is widely used as a material and is made of very hygienic unstretched or polyethylene film.

위와 같은 과정에서 보강층(20)과 열접착수지층(30)의 접합은, 보강층(20) 또는 열접착수지층(30)에 접착제를 도포하고 건조시켜 접착층(15)을 형성시킨 상태에서, 상기 보강층(20)과 열접착수지층(30)을 맞댄 상태로 압착 로울러를 통과시켜 층간 접촉을 구현하는 라미네이트(LAMINATE) 가공으로 접합을 구현할 수 있으나, 열융착 테이프를 이용하는 것과 같이 보강층(20)과 열접착수지층(30)을 손상시키지 않으면서 접합을 구현할 수 있다면 특정한 접합방법에 구애됨이 없이 적용 가능하다.Bonding of the reinforcement layer 20 and the heat-adhesive resin layer 30 in the above process, in the state in which the adhesive layer 15 is formed by applying and drying the adhesive to the reinforcement layer 20 or the heat-adhesive resin layer 30, Bonding may be implemented by laminating (LAMINATE) processing to pass the crimping roller in a state where the reinforcing layer 20 and the heat-adhesive resin layer 30 are brought back together, thereby implementing interlayer contact. If the bonding can be implemented without damaging the thermal bonding resin layer 30 can be applied without being bound to a specific bonding method.

기재필름(25)에 접합시켜 대면적 시트를 형성하기 위한 표면보호층(10)은, 그 표면에 내용물 정보(로고, 내용물 사진, 조리방법...등등)를 인쇄처리한 후 그 이면에 접착제를 도포하고 건조 챔버(30)를 이용하여 열풍 건조시켜 형성시킨다. The surface protective layer 10 for bonding to the base film 25 to form a large area sheet is printed on the surface of the contents information (logo, contents photograph, cooking method, etc.) and then adhesive is applied to the back surface thereof. Is applied and formed by hot air drying using the drying chamber 30.

It is preferable to make an application in general, and the adhesive drying continuously passes the surface protection layer 10 through the chamber 300 having the inlet 302 and the outlet 304 and the hot air is injected therein. It is good to make it dry.
