가스차단성 저온 씰링 열수축필름{low temperature sealing heat constriction film having gas barrier disposition}Low temperature sealing heat constriction film having gas barrier disposition}

본 발명은 가스차단성 저온 씰링 열수축필름에 관한 것으로, 더 상세하게는 가스 차단율과 차단 시간을 연장하고, 열수축 포장시 찢어지는 현상에 대한 내충격성을 향상시킬 수 있도록 발명된 것이다.The present invention relates to a gas barrier low temperature sealing heat shrink film, and more particularly, to extend gas blocking rate and breaking time, and to improve impact resistance against tearing during heat shrink packaging.

일반적으로, 식품포장에 사용되는 포장재는 피포장물의 변패를 방지하고 선도저하를 최소화하기 위하여 가스 및 수분 차단성이 우수해야한다.In general, packaging materials used for food packaging should have excellent gas and moisture barrier properties in order to prevent deterioration of the package and to minimize freshness.

특히 육류 제품과 육류로 가공된 육가공식품의 경우에는 다량의 수분을 함유하고 주변 온도에 의해 쉽게 변질되는 문제점이 있어 냉장보관을 요하고, 유동 과정 중에 신선도가 쉽게 저하되는 폐단이 있는 것이다.In particular, meat products and processed meat processed meat is a problem that contains a large amount of moisture and easily deteriorated by the ambient temperature requires refrigeration storage, there is a closed end that freshness is easily reduced during the flow process.

따라서 근래에는 육가공 제품을 포장하는 포장재로써 열에 의해 수축되는 열 수축필름을 사용하고 있는 실정이다.Therefore, in recent years, the use of heat shrinkable film shrinkage by heat as a packaging material for packaging meat products.

즉, 열 수축 필름에 육가공 제품을 넣은 다음 열을 가하면 제조 시 설정된 수축율로 그 폭 방향과 길이방향으로 수축하면서 내부의 공기를 외부로 배출하면서 내부를 진공상태로 간편히 밀폐시키고 포장할 수 있게 되는 것이다.In other words, if the meat product is placed in a heat shrinkable film and then heat is applied, the shrinkage in the width direction and the lengthwise direction at the shrinkage rate set at the time of manufacture allows the inside to be easily sealed and packed in a vacuum while the air is discharged to the outside. .

이러한 육가공 제품 포장용 열 수축 필름은 미열의 온도에서도 쉽게 수축되도록 에틸렌 비닐 아세테이트(이후 EVA로 칭함 ; Ethylene Vinyl Acetate)와 같은 미온실링수지로 제조되어 이 열 수축 필름을 수축시키기 위해 가해지는 열에 의한 육가공 제품의 손상을 방지한다.The heat shrinkable film for packaging meat products is made of luke-sealing resins such as ethylene vinyl acetate (hereinafter referred to as EVA; Ethylene Vinyl Acetate) so that the shrinkable film shrinks easily even at a low temperature, and the heat processed meat product is applied to shrink the heat shrinkable film. To prevent damage.

또한, 육가공 제품 포장용 열 수축 필름은 통상의 열 수축 필름의 제조장치와 동일하게 합성수지 원료를 용융시켜 압출하는 압출기와, 이 압출기에서 압출된 원료를 두겹의 필름형상으로 형성하면서 미연신 상태의 필름을 필요로 하는 수축률을 가지도록 연신시키는 연신기와, 이 연신기를 통해서 제조된 필름을 이송하여 권취하는 이송권취기로 구성된다.In addition, the heat shrink film for packaging meat products is an extruder that melts and extrudes a synthetic resin raw material in the same manner as a conventional apparatus for producing a heat shrink film, and forms an unstretched film while forming the raw material extruded by the extruder in a double film form. It consists of the drawer which draws | stretches so that it has a required shrinkage | contraction rate, and the transfer winder which conveys and winds up the film manufactured through this drawer.

한편 근래에는 열 수축필름이 내부에 육가공제품을 삽입한 후 수축되어 밀폐된 상태에서 외부의 공기 및 물의 침입을 방지하여 육가공제품의 신선도를 장기간 유지할 수 있도록 다층 구조로 제조되고 있는 실정이다.On the other hand, in recent years, the heat shrink film is manufactured in a multi-layer structure so as to maintain the freshness of the processed meat products by inserting the processed meat products therein to prevent the intrusion of outside air and water in a sealed state.

종래 육가공 제품 포장용 열 수축 필름은 제조된 후 두 겹의 필름이 밀착되어 있어, 그 마찰력에 의해 두 겹의 사이를 벌려 포장하고자 하는 육가공 제품을 삽입하기 어려운 문제점이 있었던 것이다.The heat shrink film for packaging conventional meat products has been a problem that it is difficult to insert the meat products to be packaged to open the two layers by the friction force after the two-layer film is in close contact with each other.

따라서 육가공 제품이 포장 시 외부에서 노출되는 시간이 길어지고, 이로 인해 신선도가 저하되는 폐단이 있으며, 포장작업의 작업효율이 저하되는 문제점이 있었던 것이다.Therefore, the time is exposed to the outside during the packaging of the processed meat products, there is a closed end is reduced due to the freshness, there was a problem that the work efficiency of the packaging operation is reduced.

또한, 육가공 제품 포장용 열 수축 필름 내부에 육가공 제품을 삽입한 후 수축할 경우 필름과 육가공 제품이 밀착되어 소비자가 포장된 육가공 제품을 조리하기 위하여 포장을 벗길 경우 필름 내측면에 육가공 제품이 들러붙어 떨어지게 되는 문제점이 있었으며, 과도하게 수축될 경우 그 수축에 의해 육가공 제품이 가압되어 그 형상이 변해 외관미를 저하시키는 폐단이 있었던 것이다.In addition, when the meat product is inserted into the heat shrink film for packaging the meat product and then contracted, the film and the meat product are in close contact with each other, so that the meat product sticks to the inner side of the film when the consumer peels off the package to cook the packaged meat product. There was a problem that, when excessively contracted, the meat products are pressed by the contraction, the shape is changed, there was a closed end to reduce the appearance beauty.

본 고안의 목적은 미열의 온도로 열 수축되는 필름의 내측면에 파우더층이 구비되어 이 파우더층에 의해 두 겹의 필름이 달라붙는 마찰력을 최소화하여 포장 시 두 겹의 필름이 잘 떨어지게 함으로써 포장이 용이하고, 포장 시 외관미와 포장을 쉽게 벗겨 낼 수 있는 포장용 열 수축 필름을 제공하는 데 있다 The purpose of the present invention is to provide a powder layer on the inner surface of the film heat-shrinked at a sub-heat temperature, thereby minimizing the frictional force of the two layers of film adhered by the powder layer so that the two layers of the film fall off during packaging. To provide a heat shrink film for packaging that is easy and can easily peel off appearance and packaging during packaging.

도 1은 본 발명의 단면구조를 보인 단면도이다.1 is a cross-sectional view showing a cross-sectional structure of the present invention.

도 2는 도 1의 일부 확대 단면도이다.2 is a partially enlarged cross-sectional view of FIG. 1.

본 발명의 목적은 미열의 가열에도 열 수축되는 재질로 다중겹의 튜브형상으로 제조된다.An object of the present invention is made of a multi-ply tube shape made of a material that is heat-shrinkable even under mild heating.

즉, 도 1에서 도시한 바와 같이 열 수축필름은 다중겹으로 성형되면서도 전체 두께가 얇은 필름부재가 두 겹으로 겹쳐져 양 측단이 각각 길이 방향으로 이어져 두 겹의 필름을 벌여 그 사이로 육가공 제품을 삽입하여 포장할 수 있고, 삽입되어 포장되는 육가공 제품의 크기에 맞게 그 길이를 절단하여 사용할 수 있도록 제조된다.That is, as shown in Figure 1, the heat shrinkable film is molded in multiple layers, but the entire thickness of the thin film member is overlapped in two layers, so that both ends are extended in the longitudinal direction, thereby earning two layers of film and inserting the processed meat product therebetween. It can be packaged and manufactured so that its length can be cut to fit the size of the meat product to be inserted and packaged.

본 발명의 가장 내측에는 미열의 가열에도 열 수축되도록 연신처리되어 가열 시 수축되어 그 내부를 실링시키는 미온실링수지층(10)이 위치된다.At the innermost side of the present invention, the lukewarm sealing resin layer 10 is stretched so as to heat shrink even when heated under heat, and shrinks when heated to seal the inside thereof.

상기 미온실링수지층(10)은 미열의 온도에도 열 수축이 용이한 에틸렌 비닐 아세테이트(이후 EVA로 칭함 ; Ethylene Vinyl Acetate)로 형성되며, 이 EVA수지는 열 수축 필름 제조장치(미도시)의 압출기에서 압출된 후 연신기에서 미열의 온도에도 제품의 포장을 위한 수축율로 수축되도록 연신 처리되어 제조된다.The mil sealing resin layer 10 is formed of ethylene vinyl acetate (hereinafter referred to as EVA; Ethylene Vinyl Acetate) which is easy to heat shrink even at a low temperature, the EVA resin is an extruder of a heat shrink film manufacturing apparatus (not shown) After being extruded in the drawing machine is drawn and drawn to shrink at a shrinkage rate for the packaging of the product even at the temperature of the mild heat.

또 미온실링수지층(10)은 두께가 얇은 원통형의 튜브형상으로 제조된 후 롤러에 의해 양 측단이 접혀지면서 두겹으로 겹쳐져 형성되는 것이다.In addition, the lukewarm sealing resin layer 10 is formed in a thin cylindrical tube shape and then formed by overlapping two sides while being folded at both sides by a roller.

이때, 두 겹으로 겹쳐진 미온실링수지층(10)의 내부에 미세한 인체에 무해한 파우더를 전면에 걸쳐 고르게 뿌려져 롤러에 의해 압착되어 맞붙는 미온실링수지층(10) 간의 접촉을 방지할 수도 있다.At this time, evenly spread the powder harmless to the human body finely in the inside of the two layers of the luke-sealing resin layer 10 overlapped by the roller may be prevented contact between the luke-sealing resin layer (10).

여기서 미온실링수지층(10)은 미열의 온도를 가열해도 필요한 수축율을 얻을 수 있는 EVA수지로 형성되어 포장 시 필름부재를 수축시키기 위해 가열되는 온도에 의해 육가공 제품의 변질을 방지하고 신선도를 유지할 수 있게 되는 것이다.The lukewarm sealing resin layer 10 is formed of an EVA resin that can obtain the required shrinkage rate even when the temperature of the heat is heated to prevent deterioration of the processed meat product and maintain freshness by the temperature heated to shrink the film member during packaging. Will be.

한편, 상기 미온실링수지층(10)은 미열의 고온에도 필요한 수축율을 얻을 수 있는 장점이 있으나, 가스 투과율이 높아 포장 후 장기간 보관 시 미세한 틈으로 외부의 공기가 유입되어 포장된 육가공 제품의 선도를 저하시키는 문제점이 있는 것이다.On the other hand, the lukewarm sealing resin layer 10 has the advantage of obtaining the required shrinkage even at high temperatures of the low heat, but the gas permeability is high, the long-term storage after packaging, the outside air flows into the fine gap to lead the packaged meat products There is a problem to degrade.

이러한 문제점을 해결하기 위하여 상기 미온실링수지층(10)의 외측에 접착성이 있는 접착제로 형성되는 접착제층(3)으로 제1나이론층(20)과 가스 차단성이 우수한 가스차단수지층(40) 및 이 가스차단수지층(40)의 외측으로 물에 강하고, 방수성이 우수한 제2나이론층(50)이 순차적으로 적층하게 된다.In order to solve this problem, the first nylon layer 20 and the gas barrier resin layer 40 having excellent gas barrier properties as an adhesive layer 3 formed of an adhesive with an adhesive on the outside of the meso sealing resin layer 10. And the second nylon layer 50 which is resistant to water and excellent in water resistance to the outside of the gas barrier resin layer 40 are sequentially stacked.

그리고, 제2나이론층(50)의 외부로 접착제층(60)을 이용해 마감수지층(70)을 더 형성하게 된다.Then, the finishing resin layer 70 is further formed by using the adhesive layer 60 to the outside of the second nylon layer 50.

상기 가스차단수지층(40)이 미온실링수지층(10)에 쉽게 접착되지 못하므로 접작체층(30)을 이용해 미온실링수지층(10)과 가스차단수지층(40) 사이에 제1나이론층(20)을 개재하여 미온실링수지층(10)의 외측에서 완전히 접착되어 고정되도록 하는 것이다.Since the gas barrier resin layer 40 is not easily adhered to the lukewarm sealing resin layer 10, the first nylon layer is formed between the lukewarm sealing resin layer 10 and the gas barrier resin layer 40 using the graft layer 30. It is to be completely adhered to and fixed to the outside of the lukewarm sealing resin layer 10 through the (20).

제1나이론층(20)은 상기 가스차단수지층(40)이 가스를 차단성은 우수하나 물에 약해 쉽게 물을 투과시키고, 물에 의해 그 가스 차단성이 저하되는 문제점이 발생되므로 물로부터 상기 가스차단수지층(40)과 미온실링수지층(10)을 보호하는 역할을 하는 것이다.The first nylon layer 20 has a problem that the gas barrier resin layer 40 is excellent in blocking gas, but weak in water, so that water is easily penetrated and the gas barrier property is deteriorated by water. It will serve to protect the blocking resin layer 40 and the lukewarm sealing resin layer (10).

즉, 상기 미온실링수지층(10)의 외측에 가스 차단성은 우수한 반면 물에 약한 가스차단수지층(40)을 제1나이론층(20)에 의해 육가공 제품의 포장 후 장기간 보관 할 경우 외부의 공기와 습기가 미온실링수지층(10) 내부로 유입되는 것을 방 지하게 되는 것이다.That is, when the gas barrier resin layer 40 having excellent gas barrier property on the outside of the lukewarm sealing resin layer 10 is stored for a long time after packaging the processed meat product by the first nylon layer 20 by external air, And it is to prevent the moisture from entering the inside of the lukewarm sealing resin layer (10).

따라서 포장된 육가공 제품의 신선도를 유지할 수 있는 것이다.Therefore, it is possible to maintain the freshness of the packaged meat products.

한편, 상기 가스차단수지층(40)은 가스차단성이 우수한 에틸렌 비닐알코올(EVOH; Ethylene Vinyl Alcohol) 또는 염화 비닐덴 수지(PVDC:Poly Vinyl Dene Chloride) 중에 어느 하나의 성분을 선택하여 제조하게 된다.On the other hand, the gas barrier resin layer 40 is prepared by selecting any one component of ethylene vinyl alcohol (EVOH; Ethylene Vinyl Alcohol) excellent gas barrier properties (PVDC: Poly Vinyl Dene Chloride).

또, 제1나이론층(20)과 제2나이론층(50)은 방수성이 우수하고 강도를 증가시켜 가스차단 효과와 아울러 물에 대해 강한 나일론수지로 제조된다.In addition, the first nylon layer 20 and the second nylon layer 50 are excellent in water resistance and increase in strength, and are made of a nylon resin resistant to water as well as a gas barrier effect.

그리고, 제2나이론층(50)의 외부에서 접착제층(60)에 의해 일체로 접착되는 마감수지층(70)은 가스차단성 저온 씰링 열수축필름 전체를 충격과 인장으로 인해 변형되는 것을 보호하게 된다.In addition, the finishing resin layer 70 which is integrally bonded by the adhesive layer 60 on the outside of the second nylon layer 50 protects the entire gas barrier low temperature sealing heat shrink film from being deformed due to impact and tension.

마감수지층(70)은 폴리프로필렌(PP: Poly Propylene)이 적합하다.The finishing resin layer 70 is suitable for polypropylene (PP).

상기 접착제층(30)(60)은 나이론이나 폴리플로필렌과 같은 타 수지필름을 일체로 접합시킬 수 있는 수지계 접착 성분이면 만족한다.The adhesive layers 30 and 60 are satisfactory as long as they are a resin adhesive component capable of integrally bonding other resin films such as nylon and polyflofilene.
