Description
본 발명은 진공 포장용 필름에 관한 것으로 더 상세하게는 식품을 진공상태로 밀봉하여 포장하는 필름의 일면에 공기통로를 형성하여 식품을 진공상태로 포장할 경우 필름의 하부측에 존재하는 공기가 배출되지 않고 잔존하는 것을 방지할 수 있도록 발명된 것이다.The present invention relates to a film for vacuum packaging, and more particularly, to form an air passage on one surface of a film for sealing food in a vacuum state and packaging the food in a vacuum state, the air present in the lower side of the film is not discharged. It is invented to prevent the remaining without.
일반적으로 미국을 비롯한 각국에서는 장기간 보관을 필요로 하는 육류나 육류 가공품을 포함하는 식품류의 경우 공기에 의한 변질을 방지하기 위하여 진공 포장용 필름 내에 식품류를 삽입한 후 이 진공 포장용 필름 내부를 에어펌프 또는 기타 진공장치등을 이용하여 진공처리한 후 입구를 밀봉하여 보관하였다.In general, in the United States and other countries, foods containing meat or processed meat products that require long-term storage are inserted with foods in a vacuum packaging film to prevent air deterioration, and then the inside of the vacuum packaging film is air pump or other. After vacuuming using a vacuum apparatus or the like, the inlet was sealed and stored.
그리고, 특히 미국등과 같이 주택가와 상가가 멀리 떨어져 한번에 다량의 식품류를 구입하여 장기간 보관하는 나라의 가정에서는 상기한 바와 같이 진공 포장용 필름을 사용하여 식품류를 진공포장하는 것이 일반화되어 있는 실정이다.In addition, especially in the United States, such as the United States, where the residential area and the shopping mall is far away from buy a large amount of food at a time and stored for a long time as described above it is common to vacuum packaging foods using a vacuum packaging film as described above.
한편, 통상적으로 사용되는 진공 포장용 필름은 도 1에서 도시한 바와 같이 두겹의 필름부재(10')로 형성되어 양측단이 열압착으로 밀봉되어 있으며, 포장에 필요한 길이로 절단하여 그 하단을 열압착으로 밀봉한 후 상단에 형성된 개구부(20')를 통하여 식품류를 삽입하도록 되어있다.On the other hand, a vacuum packaging film that is commonly used is formed of a two-layer film member (10 ') as shown in Figure 1, both ends are sealed by thermocompression, cut to the length required for packaging and the lower end of the thermocompression bonding After the sealing, food is inserted through the opening 20 'formed at the top.
그리고, 상기한 진공 포장용 필름(1') 내부에 개구부(20')를 통해 보관하고자 하는 식품류를 삽입한 후 에어펌프나 기타 진공장치를 이용하여 진공 포장용 필름(1') 내부의 공기를 배출시켜 진공처리한 후에 상기 개구부(20')를 일정온도 이상의 열을 가하여 열압착하여 밀봉시켜 보관하는 것이다.Then, after inserting foods to be stored through the opening 20 'into the vacuum packaging film 1', the air inside the vacuum packaging film 1 'is discharged using an air pump or other vacuum apparatus. After the vacuum treatment, the opening 20 'is sealed by thermal compression by applying heat above a predetermined temperature.
그러나, 상기한 종래의 진공 포장용 필름(1')은 식료품을 삽입하고, 진공장치를 이용하여 그 내부의 공기를 빼낼 경우 진공장치 부근의 공기가 일시에 빠져 나가면서 두 겹의 필름부재(10')가 서로 밀착하게 되어 이 밀착된 하부에 존재하는 공기가 배출되지 않고 잔존하게 되는 문제점이 있었던 것이다.However, in the conventional vacuum packaging film 1 ', when the food is inserted and the air inside thereof is drawn out using the vacuum apparatus, the air in the vicinity of the vacuum apparatus escapes at once, and the double layer film member 10' ) Are in close contact with each other, so that the air existing in the lower part is not discharged and remains.
또한, 상기 문제점을 해결하기 위하여 미국 특허번호 Re. 34,929호에서는 진공 포장용 필름을 형성하는 두 겹의 필름부재 중 하나의 필름부재를 엠보싱 처리하여 와풀패턴을 가지는 복수의 돌출부를 형성하여, 이 돌출부 사이로 공기가 통과하는 유로를 형성한 것이 제안된 바 있다.In addition, US Patent No. Re. In 34,929, it has been proposed to form a plurality of protrusions having a waffle pattern by embossing one of the two film members forming the vacuum packaging film to form a flow path through which air passes between the protrusions. .
그러나, 상기한 바와 같이 종래의 진공 포장용 필름은 진공장치를 이용하여 진공처리할 경우 공기가 급격히 빠져 나가면서 두 겹의 필름부재가 서로 밀착하게 되어 이 밀착된 하부에 존재하는 공기가 배출되지 않고 잔존하게 되어 내부에 삽입된 식품류를 장기간 보관할 경우 쉽게 상하는 폐단이 발생하였던 것이다.However, as described above, the conventional vacuum packaging film has two layers of film members closely adhered to each other while the air is rapidly released when vacuuming using a vacuum apparatus, so that the air existing in the lower portion is not discharged and remains. The long term storage of foods inserted therein would easily result in spoiled lungs.
그리고, 상기한 문제점을 해결하기 위한 미국 특허번호 Re. 34,929호에서 제안된 진공 포장용 필름은 두 겹의 필름부재 중 하나의 필름부재를 암, 수 형상을가지는 엠보형태의 무늬가 형성된 열간롤러를 사용하여 와플패턴을 가지는 복수의 돌출부를 형성하고, 이 돌출부 사이에 유로를 형성하므로, 일정두께를 가지는 필름부재가 유로와 돌출부 사이에 연신되어 이 연신된 부분의 필름두께가 얇아지는 문제점이 있었던 것이다.And US Patent No. Re. The vacuum packaging film proposed in No. 34,929 forms a plurality of protrusions having a waffle pattern using a hot roller having an embossed pattern having a female and male shape in one of the two film members. Since the flow path is formed therebetween, the film member having a predetermined thickness is stretched between the flow path and the protrusion, so that the film thickness of the stretched portion becomes thin.
따라서, 제조과정 중에 필름표면에 와플패턴의 엠보싱을 형성하는 중에 손상이 발생되어 필름이 찢어지거나, 사용중에 진공장치로 공기를 흡입할 경우 필름부재가 재연신되어 필름표면에 구멍이 발생되는 등의 폐단이 있었던 것이다.Therefore, during the manufacturing process, damage occurs during the formation of the embossing of the waffle pattern on the film surface, or the film is torn, or when the air is sucked into the vacuum device during use, the film member is re-stretched and holes are formed in the film surface. There was a dissolution.
본 발명의 목적은 진공 포장용 필름의 필름부재를 굴곡시켜, 공기통로를 형성하므로서, 제조과정과 사용 중에 발생되는 필름부재의 손상을 방지할 수 있는 진공 포장용 필름을 제공하는 데 있다.An object of the present invention is to provide a vacuum packaging film that can be bent by the film member of the vacuum packaging film to form an air passage, thereby preventing damage to the film member generated during the manufacturing process and use.
본 발명의 다른 목적은 진공 포장용 필름의 필름부재에 공기통로가 형성되어 진공장치로 내부의 공기를 배출시켜 진공처리 할 경우 내부에 공기가 남지않고 완전히 진공처리 될 수 있도록 한 진공 포장용 필름을 제공하는 데 있다.Another object of the present invention is to provide a vacuum packaging film which is formed in the film member of the vacuum packaging film to discharge the air inside the vacuum apparatus to be vacuumed completely without leaving the air inside when vacuuming There is.

도 4 (a) ∼ (c)는 본 발명인 진공 포장용 필름이 제조되는 순서를 도시한 개략도이다.Fig.4 (a)-(c) is a schematic diagram which shows the procedure by which the film for vacuum packaging of this invention is manufactured.
도 5 는 본 발명의 일실시예로서 진공 포장용 필름의 주름부가 형성된 필름부재를 확대도시한 요부확대도로서, 필름부재의 외측면에 얇은 합성수지층을 밀착하여 코팅처리한 상태를 나타내고 있다.FIG. 5 is an enlarged view of a main part of an enlarged film member in which a wrinkled part of a vacuum packaging film is formed as an embodiment of the present invention, and shows a state in which a thin synthetic resin layer is closely adhered to the outer surface of the film member and coated.
즉, 도 2 ∼ 도 3에서 도시한 바와 같이 본 발명인 진공 포장용 필름(1)은 소저의 길이를 가지는 두 겹의 필름부재(10)의 양측단 및 하단부를 열압착하여 밀봉하고, 상부는 개구부(20)로 형성할 수 도 있으며, 두겹의 필름부재(10)의 양측단만을 열압착하여 밀봉한 상태로 소정길이를 가지도록 형성하여 사용자가 포장에 필요한 길이만큼 절단한 후 하단부를 열압착 밀봉하여 사용할 수 도 있다.That is, as shown in Figs. 2 to 3, the vacuum packaging film 1 of the present invention is thermocompression-sealed and sealed at both ends and lower ends of the two-ply film member 10 having the length of the bottom. 20) can also be formed, and formed to have a predetermined length in a state in which only the both ends of the double-layered film member 10 is sealed by heat compression, the user cuts to the length required for packaging, Can also be used.
그리고, 상기 필름부재(10)는 폴리에틸렌, 폴리프로필렌, 나일론등과 같이 재활용이 가능하고, 인체에 무해한 열가소성수지를 사용하는 것이 바람직하다.In addition, the film member 10 may be recycled, such as polyethylene, polypropylene, nylon, etc., and it is preferable to use a thermoplastic resin that is harmless to a human body.
또한, 상기 필름부재(10)는 두 겹중 어느 한측의 일면이 산(12)과 골(13)을 가지도록 굴곡형성된 주름부(11)가 일정간격으로 다수개 형성되며, 이 주름부(11)의 산(12) 내측에는 공기통로(14)가 형성된다.In addition, the film member 10 is formed with a plurality of wrinkles 11 formed at a predetermined interval bent so that one surface of either side of the two sides 12 and the valleys 13, the wrinkles 11 An air passage 14 is formed inside the mountain 12.
즉, 소정의 길이를 가지고, 양측단이 열압착된 두겹의 필름부재(10)로 형성된 진공 포장용 필름(1)을 포장에 필요한 길이로 절단한 후 하단부를 열압착으로 밀봉하고, 상부에 형성되는 개구부(20)를 통하여 식품류나 기타 진공포장될 물품을 삽입한 후 에어펌프나 기타 진공장치를 이용하여 진공 포장용 필름(1) 내부의 공기를 배출시켜 진공처리한 후에 상기 개구부(20)를 일정온도 이상의 열을 가하여 열압착하여 밀봉시켜 보관하는 것이다.That is, after cutting the vacuum packaging film (1) formed of a double-layered film member 10 having a predetermined length and both ends are thermally compressed to a length necessary for packaging, the lower end is sealed by thermocompression, and formed on the upper portion. After inserting foodstuffs or other items to be vacuum packed through the opening 20, the air inside the vacuum packaging film 1 is discharged using an air pump or other vacuum device to evacuate the vacuum, and then the opening 20 is kept at a predetermined temperature. The above-mentioned heat is applied, thermocompression-sealed, and stored.
그리고, 진공 포장용 필름(1)의 필름부재(10) 중 일면에 내측에 공기통로(14)가 형성된 주름부(11)가 형성되어, 상기한 바와 같이 진공장치로 급격히 진공 포장용 필름(1) 내부의 공기를 빼낼 경우 중간부분이 밀착되어 하부에 잔존하게 되는 공기가 상기 주름부(11)의 공기통로(14)를 통하여 배출되게 되는 것이다.In addition, a pleat 11 having an air passage 14 formed therein is formed on one surface of the film member 10 of the film 1 for vacuum packaging, and as described above, the inside of the film 1 for vacuum packaging rapidly. When the air is removed, the middle portion is in close contact with the air remaining in the lower portion is to be discharged through the air passage 14 of the wrinkle portion (11).
따라서, 진공 포장용 필름(1)의 내부공기를 완전히 빼내어 식품류포장 및 산업포장에 활용할 수 있으며, 특히 식품류를 포장할 경우 식품에 포함된 습기등에 의해 필름부재(10)가 밀착되어 발생되는 잔존공기를 완전히 제거할 수 있어, 식품류를 신선하게 장기간 보관할 수 있게 되는 것이다.Therefore, the internal air of the vacuum packaging film 1 can be completely taken out and utilized for food packaging and industrial packaging. In particular, when packaging foods, the remaining air generated by the film member 10 is in close contact with moisture, etc. contained in the food. It can be removed completely, keeping foods fresh for a long time.
한편, 상기 주름부(11)는 소정의 각도를 가지고 일측으로 경사지도록 하여 그 형상을 고정하여 형성하는 것이 바람직하다.On the other hand, the wrinkle portion 11 is preferably inclined to one side at a predetermined angle to form a fixed shape.
즉, 상기 주름부(11)가 수직으로 돌출될 경우 진공처리중 필름부재(10)가 밀착하면서 주름부(11)가 펴져 이 주름부(11) 내측에 형성되는 공기통로(14)가 막힐 수 있으므로, 상기 주름부(11)를 소정의 각도로 기울여 그 형상을 고정시켜 이를 방지하는 것이다.That is, when the wrinkle part 11 protrudes vertically, the film member 10 comes into close contact with the film member 10 during the vacuum treatment, so that the air passage 14 formed inside the wrinkle part 11 may be blocked. Therefore, the wrinkle part 11 is inclined at a predetermined angle to fix the shape to prevent this.
그리고, 주름부(11)가 수직으로 돌출되어 형성된 것에 비하여 크기가 줄어 냉장고나 창고등에 보관시 공간을 적게 차지하고, 사용중 돌출된 산(12)이 접촉에 의해 손상되는 것을 방지할 수 있는 것이다.In addition, the size of the corrugated portion 11 is formed to protrude vertically, so that the size is reduced and occupies less space when stored in a refrigerator or a warehouse, and the protruding acid 12 during use can be prevented from being damaged by contact.
한편, 본 발명인 진공 포장용 필름(1)의 주름부(11)를 형성하는 과정은 도 4 (a)에서 도시한 바와 같이 일정두께를 가지는 필름부재(10)를 산(12)과 골(13)모양이 형성된 암수금형(30)을 사이로 통과시키면서 필름이 변형될 수 있는 열과 주변환경을 충족시켜 산(12)이 수직으로 돌출된 주름부(11)를 형성하는 1 차 변형공정이 이루어진다.On the other hand, the process of forming the wrinkles 11 of the vacuum packaging film 1 of the present invention, as shown in Fig. 4 (a), the film member 10 having a constant thickness 12 and the valleys 13 While passing through the shape-shaped female mold 30, the primary deformation process is performed to satisfy the heat and the surrounding environment in which the film can be deformed to form the wrinkles 11 protruding vertically.
또, 이 경우 주름부(11)의 간격이나 산(12)의 높이는 필요에 따라 다양한 형상의 암수금형(30)을 사용하여 변형이 가능하다.In addition, in this case, the space | interval of the wrinkle part 11, and the height of the peak 12 can be deform | transformed using the female mold 30 of various shapes as needed.
그리고, 상기한 1 차변형공정이 이루어진 필름부재(10)는 도 4 (b)에서 도시한 바와 같이 산(12)이 소정의 각도로 기울어진 형상을 가지는 제 2 암수금형(40)을 통과시키면서 필름부재(10)의 탄력을 제로화하면서, 주름부(11)의 산(12)을 소정의 각도로 눕히는 2 차 변형공정을 거치고, 이 2 차 변형공정을 거친 필름부재(10)는 도 4 (c)에서 도시한 바와 같이 한쌍의 압축롤러(50) 사이를 통과하면서 열과 압을 받아 그 형상이 고정되는 마무리공정을 거치므로서 형성된다.In addition, the film member 10 having the primary deformation process described above passes through the second female mold 40 having a shape in which the peak 12 is inclined at a predetermined angle, as shown in FIG. While the elasticity of the film member 10 is zeroed, the film member 10 undergoes the secondary deformation process of laying the peak 12 of the wrinkle portion 11 at a predetermined angle. As shown in c) is formed through a finishing process of receiving the heat and pressure while passing between a pair of compression roller 50 is fixed in its shape.
즉, 상기한 바와 같이 본 발명은 일정두께의 필름부재(10)를 굴곡성형하여, 그 형상을 고정시켜 형성되므로, 제조공정 중 필름부재(10)의 일정부분이 연신되어 얇아져 손상되는 것을 방지할 수 있으며, 사용중에도 외부환경에 의하여 쉽게 손상되는 것을 방지할 수 있는 것이다.That is, as described above, the present invention is formed by bending the film member 10 having a predetermined thickness and fixing the shape thereof, thereby preventing a certain portion of the film member 10 from being stretched and thinned and damaged during the manufacturing process. It can be prevented from being easily damaged by the external environment during use.
한편, 상기와 같이 제조된 주름부(11)가 형성된 필름부재(10)의 외측면은 도 5에서 도시한 바와 같이 합성수지층(60)을 밀착하여 코팅처리한다.On the other hand, the outer surface of the film member 10 having the wrinkles 11 formed as described above is a coating process by close contact with the synthetic resin layer 60 as shown in FIG.
즉, 본 발명인 진공 포장용 필름(1)을 사용하여 진공처리할 경우 진공장치의 강한 흡입력에 의해 상기 주름부(11)가 펴지면서, 이 주름부(11) 내측에 형성되는 공기통로(14)를 막을 수 있으므로, 코팅처리된 합성수지층(60)이 주름부(11)의 형상을 견고히 고정하므로서, 강한 흡입력에도 주름부(11)가 펴지는 것을 방지할 수 있는 것이다.That is, when the vacuum treatment using the vacuum packaging film (1) of the present invention, the air passage (14) formed inside the wrinkle portion 11 while the wrinkle portion 11 is unfolded by the strong suction force of the vacuum apparatus. Since it can be prevented, the coated synthetic resin layer 60 is firmly fixed to the shape of the wrinkle portion 11, it is possible to prevent the wrinkle portion 11 from being unfolded even with a strong suction force.
또한, 필름부재(10)의 외측면이 코팅처리되므로서, 외관미가 증대되고, 외부접촉에 의한 손상도 함께 방지할 수 있는 것이다.In addition, since the outer surface of the film member 10 is coated, the appearance is increased, and damage due to external contact can be prevented together.
그리고, 상기 합성수지층(60)은 폴리에스테르, 폴리아미드, EVOH등의 재질로 형성하여, 진공처리 후 본 발명인 필름부재(10)가 열압착되어 밀봉할 경우에 기계적 물성이 유지되도록 하는 것이 바람직하다.In addition, the synthetic resin layer 60 is formed of a material such as polyester, polyamide, EVOH, it is preferable to maintain the mechanical properties when the film member 10 of the present invention is thermally compressed and sealed after vacuum treatment. .
상기한 본 발명의 구성에 의하면, 필름부재의 일면에 공기통로가 내측으로 형성되도록 주름부를 일정간격으로 형성하여, 두겹의 필름부재가 진공처리중 밀착되더라도, 상기 주름부의 공기통로를 통하여 진공 포장용 필름 내의 공기를 완전히 배출시켜, 용이하게 진공포장할 수 있게 되는 것이다.According to the configuration of the present invention, by forming a wrinkle portion at a predetermined interval so that the air passage is formed inward on one surface of the film member, even if the two-ply film member is in close contact during the vacuum treatment, the film for vacuum packaging through the air passage of the wrinkle portion The air inside is completely discharged, so that it can be easily vacuum packed.
또한, 일정두께의 필름부재가 굴곡 변형되어 내측에 공기통로가 형성된 주름부가 일정간격으로 반복되어 형성되므로, 필름부재의 일부분이 연신되어 얇아지므로서 발생되는 손상을 방지하고, 장기간 안전하게 사용할 수 있는 것이다.In addition, since the film member of a certain thickness is bent and deformed, and the wrinkles formed in the air passage inside are repeatedly formed at a predetermined interval, it is possible to prevent damage caused by the thinning of a portion of the film member and to use it safely for a long time. .
따라서, 식품류나 기타 물품을 완전한 진공상태로 용이하게 보관할 수 있어 식품류의 신선도를 유지할 수 있고, 내구성이 우수하여 장기간 안전하게 사용이 가능하므로 상품성이 획기적으로 증대되는 매우 유용한 발명인 것이다.Therefore, foods and other items can be easily stored in a complete vacuum state to maintain the freshness of foods, it is a very useful invention that the marketability is significantly increased because the durability is excellent and can be used safely for a long time.
