이하, 첨부된 도면을 참조하여 본 발명에 따른 통기성 비닐봉지에 대하여 더욱 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in more detail with respect to the breathable plastic bag according to the present invention.

도 1은 본 발명에 따른 통기성 비닐봉지의 전개도 이다.1 is a developed view of a breathable plastic bag according to the present invention.

도 2는 본 발명에 따른 통기성 비닐봉지를 도시한 도면이다.2 is a view showing a breathable plastic bag according to the present invention.

본 발명에 따른 통기성 비닐봉지는 직사각형의 비닐(100) 및 통기부(200)를 포함한다.The breathable plastic bag according to the present invention includes a rectangular vinyl 100 and the vent 200.

도 1에 도시된 바와 같이 비닐(100)은 폴리프로필렌(OPP:Oriented Poly Prophylene)층(110)과 폴리에틸렌(PE:Poly Ethylene)층(130)이 그 사이에 적층되는 접착층(120)에 의해 접착되어 구성된다.As shown in FIG. 1, the vinyl 100 is adhered by an adhesive layer 120 in which an polypropylene (OPP: Oriented Poly Propylene) layer 110 and a polyethylene (PE) layer 130 are laminated therebetween. It is configured.

상술한 바와 같이, 폴리프로필렌(OPP:Oriented Poly Prophylene)층(110), 폴리에틸렌(PE:polyethylene)층(130) 및 그 사이의 접착층(120)이 적층되어 형성된 비닐(100)에는 도 1에 도시된 바와 같이 접철가능 하도록 하는 제 1접철부(140)와 제 2접철부(150)가 대칭적으로 형성되어 있다. As described above, the vinyl 100 formed by laminating the polypropylene (OPP) layer 110, the polyethylene layer (PE) 130, and the adhesive layer 120 therebetween is illustrated in FIG. 1. As described above, the first folding portion 140 and the second folding portion 150 are symmetrically formed to be foldable.

도 2에 도시된 바와 같이 본 발명에 따른 통기성 비닐봉지는 직사각형의 비닐(100)이 상술한 접철부(140, 150)를 중심으로 접철된 후, 소정의 간격(D)만큼 이격된 양단(AB, CD)사이에 통기성의 미세구멍이 형성된 통기부(200)가 중앙에 부착된 후, 통기부(200)가 부착되는 방향과 수직인 방향으로 일단이 열접착 되어 형성된다.As shown in FIG. 2, the air-permeable plastic bag according to the present invention has a rectangular vinyl 100 folded around the folding portions 140 and 150, and then spaced apart from each other by a predetermined distance D. After the vent part 200 having a breathable micro-hole formed between the CD) is attached to the center, one end is thermally bonded in a direction perpendicular to the direction in which the vent part 200 is attached.

통기부(200)는 비닐(100)의 내부로 접착되어 결합되는데, 그러한 이유는 통기부(200)가 외부환경에 의해 비닐(100)로부터 탈착되는 것을 방지하기 위함이다.The vent 200 is bonded to the inside of the vinyl 100 and bonded, for this reason, to prevent the vent 200 from being detached from the vinyl 100 by an external environment.

상술한 외부환경이란 내용물이 담긴 복수의 통기성 비닐이 적층되어 이동되거나 하는 과정에서 발생하는 마찰력등이 있을 수 있다.The external environment described above may include frictional forces generated in the process of stacking and moving a plurality of breathable vinyls containing contents.

통기부(200)와 비닐(100)과의 결합은 길이방향으로 통기부(200)의 양단이 소정의 간격(d)만큼 비닐(100)의 양단(AB,CD)과 중첩된 후 소정의 열이 가해짐에 따라 열접착 되어 이루어진다.Coupling of the vent 200 and the vinyl 100 is a predetermined row after both ends of the vent 200 in the longitudinal direction overlap the both ends (AB, CD) of the vinyl 100 by a predetermined distance (d) As it is added, it is thermally bonded.

비닐(100)은 폴리프로필렌층(110)이 외부에 위치하고, 폴리에틸렌층(130)이 내부에 위치되도록 접철되는데, 상술한 바와 같이 폴리에틸렌층(130)이 내부로 위치하는 이유는 소정온도의 열이 가해질 때, 용이한 열접착이 이루어지도록 하기 위함이다.The vinyl 100 is folded so that the polypropylene layer 110 is located outside and the polyethylene layer 130 is located inside. As described above, the reason why the polyethylene layer 130 is located inside is that the heat of a predetermined temperature When applied, it is for easy thermal bonding.

또한, 폴리프로필렌층(110)과 폴리에틸렌층(130) 사이에는 자외선 차단 필름층(160)이 개재되어 비닐봉지 내부에 수용된 내용물이 자외선에 의해 변색되거나 변질되는 것을 방지한다.In addition, the UV block film layer 160 is interposed between the polypropylene layer 110 and the polyethylene layer 130 to prevent the contents contained in the plastic bag from being discolored or altered by ultraviolet rays.

상술한 바와 같이 통기부(200)가 비닐(100)의 중앙에 부착되는 경우 내용물이 담긴 복수의 통기성 비닐봉지(300)가 적층되어 통기부(200)가 막히는 상황이 발생하게 되는데, 이러한 상황을 해결하기 위해 도 3에 도시된 바와 같이 비닐(100)의 측면부에 보조 통기부(200a)가 형성될 수도 있다.As described above, when the vent 200 is attached to the center of the vinyl 100, a plurality of breathable plastic bags 300 containing the contents are stacked to block the vent 200. In order to solve this, as shown in FIG. 3, an auxiliary vent 200a may be formed at the side surface of the vinyl 100.

그리고, 도 5에 도시된 바와 같이 비닐(100)에 형성되는 접철부(140, 150)가 비대칭으로 형성되고, 그에 따라 통기부(200)의 위치도 비닐봉지(300)의 중앙이 아닌 일측면에 치우치게 형성될 수도 있다.And, as shown in FIG. 5, the folding portions 140 and 150 formed in the vinyl 100 are asymmetrically formed, and accordingly, the position of the vent 200 is not one side of the plastic bag 300. It may be formed to be biased.

상술한 구성을 가진 통기성 비닐봉지의 제조방법에 대하여 도 4를 참조하여 상세히 설명한다.A method of manufacturing a breathable plastic bag having the above-described configuration will be described in detail with reference to FIG. 4.

폴리프로필렌층(110)과 폴리에틸렌층(130)이 부착되도록 접착층(120)을 사이에 두고 폴리프로필렌층(110)과 폴리에틸렌층(130)을 적층시켜 비닐을 제조하는 단계가 이루어진다(S100).The polypropylene layer 110 and the polyethylene layer 130 is attached so that the adhesive layer 120 with the polypropylene layer 110 and the polyethylene layer 130 laminated to make a step (S100).

`S100` 단계에서 비닐봉지 내부에 수용된 내용물이 자외선에 의해 변색되거나 변질되는 것을 방지하도록, 폴리프로필렌층(110)과 폴리 에틸렌층(130) 사이에 자외선 차단 필름층(160)이 개재되어 적층되는 단계가 더 이루어지는 것이 바람직하다.The UV blocking film layer 160 is interposed between the polypropylene layer 110 and the polyethylene layer 130 to prevent the contents contained in the plastic bag from being discolored or deteriorated by ultraviolet rays at step S100. It is preferred that further steps are taken.

`S100`단계에서 제조되어 담기는 내용물의 용량에 따라 상이한 크기로 절단된 직사각 형상의 비닐(100)에 접철부(140, 150)를 형성시키는 단계가 이루어진다(S200).The step of forming the folding parts (140, 150) in the rectangular shape of the vinyl 100 cut into different sizes according to the capacity of the contents produced and contained in the 'S100' step (S200).

후술되는 접철단계에서 접철이 이루어지는 경우, 비닐(100)의 양단(AB, CD)사이에 소정의 간격(D)만큼 이격될 수 있도록 `S200`단계에서 접철부(140, 150)을 형성시키는 것이 바람직 하다.When folding is performed in the folding step to be described later, it is to form the folding parts (140, 150) in the step 'S200' to be spaced apart by a predetermined distance (D) between both ends (AB, CD) of the vinyl 100 desirable.

`S200`단계에서 형성된 접철부(140, 150)를 중심으로 비닐(100)을 접철시키는 단계가 이루어진다(S300).A step of folding the vinyl 100 around the folding parts 140 and 150 formed in step S200 is performed (S300).

`S300`단계에서 접철이 이루어질 때, 비닐(100)의 폴리프로필렌층(110)이 외부에 위치하고, 폴리에틸렌층(130)이 내부에 위치되도록 접철되는것이 바람직한데, 폴리에틸렌층(130)이 내부로 위치하는 이유는 소정온도의 열이 가해질 때, 마주보게 되는 폴리에틸렌층(130)간의 열접착이 폴리플로필렌층(110)보다 탁월하게 이루어지기 때문이다.When folding is made in the 'S300' step, it is preferable that the polypropylene layer 110 of the vinyl 100 is located outside, the folding is so that the polyethylene layer 130 is located inside, the polyethylene layer 130 is inside The reason for the location is that when the heat of a predetermined temperature is applied, thermal bonding between the polyethylene layers 130 facing each other is superior to that of the polyfloylene layer 110.

`S300`단계에서 접철이 이루어짐에 따라 이격되어 형성되는 소정의 간격사이에 통기부(200)를 형성시키는 단계가 이루어진다(S400).In step S300, as the folding is performed, a step of forming the ventilation unit 200 is formed between predetermined intervals that are formed to be spaced apart (S400).

통기부(200)는 미세한 구멍이 형성된 부직포로 이루어져 있으며, 통기부(200)의 길이방향으로 소정의 간격(d)만큼이 비닐(100)의 양단(AB, CD)과 중첩되어 부착되어 결합된다.Vent portion 200 is made of a non-woven fabric having a fine hole, overlapping and bonded to both ends (AB, CD) of the vinyl 100 by a predetermined distance (d) in the longitudinal direction of the vent portion (200) .

그리고, 통기부(200)가 비닐(100)의 양단(AB, CD) 사이의 이격된 간격(D)을 메우는 방식으로 비닐(100)과 통기부(200)의 결합이 이루어지는데, 이때, 비닐(100)과 통기부(200)의 결합은 비닐(100)과 통기부(200)가 소정의 간격(d)만큼 중첩된 상태에서 소정의 열이 가해져 열접착되어 이루어진다.In addition, the ventilation unit 200 is coupled to the vinyl 100 and the ventilation unit 200 in such a manner as to fill the spaced intervals D between both ends AB and CD of the vinyl 100. Coupling of the 100 and the vent 200 is made by applying a predetermined heat in a state in which the vinyl 100 and the vent 200 are overlapped by a predetermined interval (d).

한편, 상술한 통기부(200)가 비닐봉지(300)의 중앙에 형성됨에 따라 내용물이 담긴 복수의 통기성 비닐봉지(300)가 적층되어 통기부(200)가 막히는 상황이 발생하여 통기부(200)의 기능이 제대로 수행될 수 없는데, 이러한 상황을 해결하기 위해 도 3에 도시된 바와 같이 비닐(100)의 측면부에 별도의 보조 통기부(200a)가 형성될 수 도 있다.On the other hand, as the above-described ventilation unit 200 is formed in the center of the plastic bag 300, a plurality of breathable plastic bags 300 containing the contents are stacked to block the ventilation unit 200 occurs, the ventilation unit 200 ) Can not be performed properly, in order to solve this situation, as shown in FIG. 3, a separate auxiliary vent 200a may be formed on the side surface of the vinyl 100.

또 다른 방안으로, 도 5에 도시된 바와 같이 `S200`단계에서 비닐(100)에 대칭적으로 형성되는 접철부(150)를 비대칭적으로 형성시켜 통기부(200)의 형성위치가 중앙이 아닌 일측면으로 치우치도록 형성시킬 수 도 있다.As another method, as shown in FIG. 5, the asymmetrical formation of the folds 150 formed symmetrically on the vinyl 100 in step S200 may be performed asymmetrically so that the formation position of the vent 200 is not centered. It may be formed to be biased to one side.

`S400`단계에서 통기부(200)형성됨에 따라 비닐(100)은 관통하는 호스와 같은 구조를 갖게 되는데, 이때 형성된 통기부(200)와 수직인 방향으로 비닐의 일단을 열접착 시키고 폐쇄시켜 비닐봉지를 완성시키는 단계가 이루어진다(S500).As the vent part 200 is formed in the 'S400' step, the vinyl 100 has a structure such as a penetrating hose. At this time, one end of the vinyl is thermally bonded and closed in a direction perpendicular to the vent part 200 formed. A step of completing the bag is made (S500).
