본 발명은 포장용 열 수축 필름에 관한 것으로 더 상세하게는 육가공 제품을 포장하는 열 수축 필름이 포장 중 두 겹의 필름이 잘 떨어져 포장이 용이하고, 포장 시 포장된 외관을 향상시킬 수 있도록 발명된 것이다.The present invention relates to a heat shrinkable film for packaging, and more particularly, a heat shrinkable film for packaging a meat product is invented so that two layers of film are well separated from each other during packaging, so that the packaging is easy and the packaged appearance can be improved. .

일반적으로 식품포장에 사용되는 포장재는 피포장물의 변패를 방지하고 선도 저하를 최소화하기 위하여 가스 및 수분 차단성이 우수해야한다.In general, the packaging materials used for food packaging should have excellent gas and water barrier properties to prevent deterioration of packaged products and to minimize freshness degradation.

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 아세트이트(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 it shrinks easily even at low temperature, and the heat processed by heat applied to shrink the heat shrinkable film. Prevent damage to the product.

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.

그러나 종래의 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.However, since the conventional heat shrinkable film for packaging a meat product is manufactured, two layers of films are in close contact with each other, so that the meat products to be packaged with the friction force between the two layers are difficult to insert.

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 발명의 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.
An object of the present invention is to provide a powder layer on the inner surface of the film that is heat-shrinked at a sub-heat temperature to minimize 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. It is to provide a heat shrinkable film for packaging that can be easily peeled off appearance and packaging during packaging.

이러한 본 발명의 목적은 미열의 가열에도 열 수축되는 재질로 제조되며, 양 측이 길이 방향으로 이어져 두 겹을 이루는 필름부재(1)로 형성된 것에 있어서, The object of the present invention is made of a material that is heat shrink even in the heating of the mild heat, both sides are formed in the film member (1) formed in two layers extending in the longitudinal direction,

상기 필름부재(1)는 미열의 가열에도 열 수축되도록 연신처리되어 가열 시 수축되어 그 내부를 실링시키는 미온실링수지층(10)과;The film member (1) is stretched so that the heat shrink even in the heating of the mild heat is shrunk during heating to seal the inside of the lukewarm sealing resin layer (10);

상기 미온실링수지층(10)의 내측면에 미세한 분말이 전면에 고르게 뿌려져 형성되는 파우더층(20)으로 구성된다.It is composed of a powder layer 20 is formed by spraying the fine powder evenly on the inner surface of the lukewarm sealing resin layer 10.

즉, 상기 파우더층(20)이 두 겹을 이루는 필름부재(1)의 미온실링수지층(10) 사이의 마찰을 감소시켜 미온실링수지층(10)의 사이를 용이하게 벌려 포장하고자 하는 육가공 제품을 삽입하여 간단히 포장할 수 있는 것이다.That is, the powder layer 20 is to reduce the friction between the luke-sealing resin layer 10 of the film member (1) forming a double layer to easily open the meat products to wrap between the luke-sealing resin layer (10) It can be simply inserted and packed.

본 발명의 바람직한 실시 예를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.When described in detail with reference to the accompanying drawings a preferred embodiment of the present invention.

도 1 은 본 발명인 포장용 열 수축 필름의 기본 형상을 도시한 사시도로서, 필름부재의 양 측 단이 접혀져 밀폐되고, 내측면에는 미세한 분말이 뿌려져 파우더층이 형성된 것을 나타내고 있다.1 is a perspective view showing the basic shape of the heat shrink film for packaging according to the present invention, both ends of the film member is folded and sealed, and the inner surface is sprinkled with fine powder to form a powder layer.

도 2 는 본 발명인 포장용 열 수축 필름의 요부확대 단면도로서, 미온실링수지층의 외측으로 가스차단수지층과, 방수수지층이 형성된 것을 나타내고 있다.Fig. 2 is an enlarged cross-sectional view of the main portion of the packaging heat shrinkable film of the present invention, showing that a gas barrier resin layer and a waterproof resin layer are formed outside the lukewarm sealing resin layer.

이하, 도 1에서 도시한 바와 같이 본 발명인 포장용 열 수축필름은 두께가 얇은 필름부재(1)가 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.Hereinafter, as shown in FIG. 1, the present invention packaging heat shrinkable film has a thin film member (1) overlapped in two layers so that both side ends are extended in the lengthwise 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.

상기 필름부재(1)는 미열의 온도로 가열해도 쉽게 열 수축되도록 연신처리되어 있는 미온실링수지층(10)과, 이 미온실링수지층(10)의 내측면에 미세한 분말이 전면에 골고루 뿌려져 형성되는 파우더층(20)으로 구성된다.The film member (1) is formed by spreading the fine powder on the inner surface of the luke-sealing resin layer (10) and the inner surface of the luke-sealing resin layer (10), which is stretched so as to easily heat shrink even when heated to a temperature of mild heat. It consists of a powder layer 20 to be.

상기 미온실링수지층(10)은 미열의 온도에도 열 수축이 용이한 에틸렌 비닐 아세트이트(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 연신처리되어 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 of the heat shrink film manufacturing apparatus (not shown) After being extruded in an extruder, it is stretched and manufactured to shrink at a shrinkage rate for packaging a product even at a low temperature in the drawing machine.

그리고 상기 파우더층(20)은 상기 미온실링수지층(10)이 연신기에서 연신처리 되는 중에 파우더공급기에 의해 미세한 분말을 필름부재(1) 내부로 골고루 뿌려져 형성되는 것이다.In addition, the powder layer 20 is formed by evenly spraying fine powder into the film member 1 by the powder feeder while the lukewarm sealing resin layer 10 is stretched in the stretching machine.

이 분말은 식용 시 인체에 무해하고 육가공 제품의 맛과 선도에 영향을 주지 않는 고구마 전분 등과 같은 식물성 전분을 사용한다.The powder uses vegetable starch, such as sweet potato starch, which is harmless to humans when eaten and does not affect the taste and freshness of meat products.

또 미온실링수지층(10)은 두께가 얇은 원통형의 튜브형상으로 제조된 후 롤러에 의해 압착되어 양 측단이 접혀지면서 두 겹으로 겹쳐져 형성되는 것이다.In addition, the lukewarm sealing resin layer 10 is made of a thin cylindrical tube shape is pressed by a roller is formed by overlapping in two layers while being folded at both ends.

즉, 상기한 바와 같이 두 겹으로 겹쳐진 미온실링수지층(10)의 내부에 미세한 분말들이 전면에 걸쳐 고르게 뿌려져 얇은 파우더층(20)이 형성되어 롤러에 의해 압착되어 맞붙는 미온실링수지층(10) 간의 접촉을 방지하게 되는 것이다.That is, as described above, the fine powder is evenly sprayed over the entire surface of the lukewarm sealing resin layer 10, which is overlapped in two layers, so that a thin powder layer 20 is formed and pressed and joined by the roller. It will prevent contact between them.

따라서 상기 미온실링수지층(10)이 압착되어 겹쳐져 두 겹으로 형성되어도 포장 시 그 사이를 벌리기 용이하여, 종래에 미온실링수지층(10) 간이 서로 밀착됨으로써 포장할 경우 그 사이를 벌리기 어려운 문제점을 해결할 수 있는 것이다.Therefore, even when the lukewarm sealing resin layer 10 is formed by overlapping and overlapping two layers, it is easy to open the gaps during packaging, and in the past, when the lukewarm sealing resin layers 10 are packed in close contact with each other, it is difficult to open them. It can be solved.

또한 상기 미온실링수지층(10)은 미열의 온도를 가열해도 필요한 수축율을 얻을 수 있는 EVA수지로 형성되어 포장 시 필름부재(1)를 수축시키기 위해 가열되는 온도에 의해 육가공 제품의 변질을 방지하고 신선도를 유지할 수 있게 되는 것이다.In addition, the lukewarm sealing resin layer 10 is formed of an EVA resin that can obtain the required shrinkage rate even when heated to a low temperature to prevent deterioration of the processed meat products by the temperature that is heated to shrink the film member (1) during packaging It will be able to maintain freshness.

또 파우더층(20)이 포장된 후 육가공제품이 미온실링수지층(10)에 달라붙는 것을 방지하여 소비자가 포장된 필름부재(1)를 깨끗하게 제거할 수 있으며, 포장되기 전 육가공 제품의 형태를 포장 제거 후에도 온전히 유지할 수 있게 되는 것이다.In addition, after the powder layer 20 is packaged, the processed meat product is prevented from sticking to the lukewarm resin layer 10 so that the consumer can remove the packaged film member 1 cleanly, and the form of the processed meat product before packing. You will be able to keep it intact after removing the package.

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)은 외측에 접착성이 있는 접착제로 형성되는 접착제층(30)과, 가스 차단성이 우수한 가스차단수지로 형성되어 상기 접착제층(30)의 외측에 접착되는 가스차단수지층(40)과, 이 가스차단수지층(40)의 외측으로 물에 강하고, 방수성이 우수한 방수수지로 형성된 방수수지층(50)이 순차적으로 적층되어 형성된다.In order to solve this problem, the lukewarm sealing resin layer 10 is formed of an adhesive layer 30 formed of an adhesive with an adhesive on the outside and a gas barrier resin having excellent gas barrier property, so that the adhesive layer 30 The gas barrier resin layer 40 adhered to the outside and the waterproof resin layer 50 formed of a waterproof resin that is resistant to water and excellent in water resistance to the outside of the gas barrier resin layer 40 are sequentially formed.

상기 접착제층(30)은 상기 가스차단수지층(40)이 미온실링수지층(10)에 쉽게 접착되지 못하므로 그 사이에 미온실링수지층(10)과 가스차단수지층(40) 사이에 구비되어 미온실링수지층(10)의 외측에 가스차단수지층(40)이 완전히 접착되어 고정 되도록 하는 것이다.Since the gas barrier resin layer 40 is not easily adhered to the lukewarm sealing resin layer 10, the adhesive layer 30 is provided between the lukewarm sealing resin layer 10 and the gas barrier resin layer 40 therebetween. The gas barrier resin layer 40 is completely adhered to and fixed to the outside of the lukewarm sealing resin layer 10.

또 방수수지층(50)은 상기 가스차단수지층(40)이 가스를 차단성은 우수하나 물에 약해 쉽게 물을 투과시키고, 물에 의해 그 가스 차단성이 저하되는 문제점이 발생되므로 물로 부터 상기 가스차단수지층(40)과 미온실링수지층(10)을 보호하는 역할을 하는 것이다.In addition, the waterproof resin layer 50 has excellent gas barrier property, but the gas barrier resin layer 40 is weak against water, so that water is easily penetrated, and the gas barrier property is degraded 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 차단성이 우수한 가스차단수지층(40)과 물에 약한 가스차단수지층(40)을 물로부터 보호하는 방수수지층(50)이 형성되어 육가공 제품의 포장 후 장기간 보관 할 경우 외부의 공기와 습기가 미온실링수지층(10) 내부로 유입되는 것을 방지하여 포장된 육가공 제품의 신선도를 유지할 수 있는 것이다.That is, the water-resistant resin layer 50 which protects the gas barrier resin layer 40 having excellent gas barrier property and the gas barrier resin layer 40 which is weak to water is formed on the outside of the lukewarm sealing resin layer 10. When the meat products are stored for a long time after packaging, the outside air and moisture may be prevented from flowing into the lukewarm resin layer 10 to maintain the freshness of the packaged meat products.

한편, 상기 가스차단수지층(40)은 가스차단성이 우수한 에틸렌 비닐알코올(EVOH; Ethylene Vinyl Alcohol)로 형성되고, 상기 방수수지층(50)은 방수성이 우수하고 물에 강한 나일론수지로 형성하며, 이 외 외부로 부터의 가스유입과 물을 차단할 수 있는 어떠한 수지도 사용할 수 있으며 이는 본 발명의 구성에 포함됨을 밝혀둔다.On the other hand, the gas barrier resin layer 40 is formed of ethylene vinyl alcohol (EVOH; Ethylene Vinyl Alcohol) excellent gas barrier properties, the waterproof resin layer 50 is formed of a nylon resin excellent in water resistance and strong water, In addition, any resin that can block gas inflow and water from the outside can be used, which is included in the configuration of the present invention.

상기한 본 발명의 구성에 의하면, 포장용 필름의 미온실링수지층 내부에 파우더층이 형성되어 두 겹의 미온실링수지층 사이의 마찰을 최소화하여 육가공 포장용 필름의 내부로 육가공 제품을 삽입하여 포장할 경우 쉽게 필름부재를 벌려 포장 작업할 수 있게 되는 것이다.According to the configuration of the present invention, when the powder layer is formed inside the lukewarm resin layer of the packaging film to minimize the friction between the two layers of lukewarm resin layer to insert the meat products into the packaging of the meat packaging film packaging The film member can be easily opened to work on packaging.

또한 포장용 필름이 열 수축되어 육가공 제품을 포장한 상태에서 파우더에 의해 포장된 상태에서 미온실링수지층과 육가공제품 사이의 직접적인 접촉을 최소화하여 장기간 보관 중 필름에 육가공 제품이 눌러 붙지 않고 이로 인해 육가공 제품의 형상을 그대로 유지한 상태로 쉽고 깨끗하게 포장을 벗겨 낼 수 있는 것이다.In addition, the packaging film is heat-shrinkable to minimize the direct contact between the lukewarm resin layer and the processed meat product in the state of packing the processed meat product, so that the processed meat product does not stick to the film during long-term storage. You can peel off the packaging easily and cleanly while keeping the shape of the intact.

포장 시 열 수축 필름이 과도하게 수축되어 포장되는 유가공 제품의 형상을 변형시키는 것을 방지하고 포장 후 외관미를 증대시킬 수 있는 것이다.It is possible to prevent the heat shrink film from being excessively shrunk during packaging to deform the shape of the packaged dairy product and increase the appearance after packaging.

따라서 포장 작업의 편의성을 증대시킴은 물론 소비자의 구매욕구를 증대시키고 구매 후 소비자의 만족도를 향상시키는 매우 유용한 발명인 것이다.

Therefore, it is a very useful invention that not only increases the convenience of the packaging operation but also increases the consumer's desire to purchase and improves the customer's satisfaction after purchase.
