도 1에 도시한 바와 같이 본 발명의 일실시예에 의한 식품 포장용 방수포장재(10)는 포장용 종이(12)와, 상기 포장용 종이(12)의 안쪽면에 저밀도 폴리에틸렌과 고밀도 폴리에틸렌을 4:3으로 혼합한 용융 혼합물이 융착된 방수층(14)으로 구성되어 있다. As shown in FIG. 1, the waterproof packaging material 10 for food packaging according to an embodiment of the present invention has a low density polyethylene and a high density polyethylene at 4: 3 on the inner side of the packaging paper 12 and the packaging paper 12. The mixed melt mixture is composed of a waterproof layer 14 that is fused.

다음에, 이와 같이 구성된 본 발명의 일실시예에 의한 식품 포장용 방수포장재의 작용 및 효과에 대하여 설명한다.Next, the operation and effects of the food packaging waterproof packaging material according to one embodiment of the present invention configured as described above will be described.

본 발명의 식품 포장용 방수포장재(10)는 접착력을 낮추기 위하여 저밀도 폴리에틸렌과 고밀도 폴리에틸렌을 4:3으로 혼합한 폴리에틸렌 혼합물을 폴리에틸렌의 용융온도(320℃) 보다 현저히 낮은 260℃ 내지 270℃의 온도에서 용융시킨 용융 물을 상기 포장용 종이(12)의 안쪽면에 융착시켜서 방수층(14)을 적층시킨 구조이므로, 상기 포장용 종이(12)와 상기 방수층(14)이 견고하게 부착되어 있지 않아 본 발명의 식품 포장용 방수포장재를 폐기시킬 경우에 방수포장재의 한쪼 코너부를 일정 간격을 두고 손으로 잡고 비비면 상기 방수층(14)이 포장용 종이(12)로부터 박리된다.Waterproof packaging material 10 for food packaging of the present invention is melted at a temperature of 260 ℃ to 270 ℃ a polyethylene mixture of a mixture of low density polyethylene and high density polyethylene in 4: 3 to lower the adhesive strength significantly lower than the melting temperature of the polyethylene (320 ℃) Since the melted melt is fused to the inner surface of the packaging paper 12 to laminate the waterproof layer 14, the packaging paper 12 and the waterproof layer 14 are not firmly adhered to each other. When the waterproof packaging material is discarded, the waterproof layer 14 is peeled off from the wrapping paper 12 when the handful of corners of the waterproof packaging material are rubbed by hand at regular intervals.

이때, 상기 방수층(14)과 상기 포장용 종이(12)의 서로 대향하는 부분을 양쪽 손으로 잡고 서로 멀어지는 방향으로 잡아당기면, 상기 방수층(14)과 상기 포장용 종이(12)가 용이하게 분리된다.At this time, by holding the opposite parts of the waterproof layer 14 and the wrapping paper 12 with both hands and pulling in a direction away from each other, the waterproof layer 14 and the wrapping paper 12 are easily separated.

다시 말하면, 본 발명의 식품 포장용 방수포장재(10)를 가로 ㅧ 세로가 20cm ㅧ 20cm 크기의 사이즈로 시험편을 10개 제작하여 이들 시험편의 코너부로부터 일정 거리 떨어져서 양측 손으로 각각 잡고, 시험편을 5회 비빈 결과, 모든 시험편의 상기 방수층(14)이 포장용 종이(12)로부터 박리되었고, 상기 방수층(14)과 상기 포장용 종이(12)의 서로 대향하는 부분을 양쪽 손으로 잡고 서로 멀어지는 방향으로 잡아당겼더니 상기 방수층(14)과 상기 포장용 종이(12)가 용이하게 분리되었다.In other words, the watertight packaging 10 for food packaging 10 of the present invention is made of 10 test pieces in a size of 20cm ㅧ 20cm in width and length by holding each with both hands at a distance from the corners of these test pieces, and holding the test pieces five times. As a result of the emptying, the waterproof layer 14 of all the test pieces was peeled off from the wrapping paper 12, and both sides of the waterproof layer 14 and the wrapping paper 12 were held with both hands and pulled in a direction away from each other. The waterproof layer 14 and the packaging paper 12 were easily separated.

그리고, 본 발명의 식품 포장용 방수포장재(10)는 상기 포장용 종이(12) 상에 저밀도 폴리에틸렌 입자와 고밀도 폴리에틸렌 입자를 4 : 3의 비율로 혼합돤 저밀도/고밀도 폴리에틸렌 혼합물의 용융물을 융착시켜서 방수층(14)을 부착하므로, 인체에 유해한 가스가 배출되지 않으므로, 식품을 포장하는데 아무런 문제가 없다.In addition, the waterproof packaging material 10 of the present invention is to mix the low-density polyethylene particles and high-density polyethylene particles in the ratio of 4: 3 on the packaging paper 12 by fusing the melt of the low-density / high-density polyethylene mixture waterproof layer 14 ), There is no problem in packaging food because no harmful gas is emitted.

(melting step).

다음에, 상기 용융공정 후에 포장용 종이(12)가 감겨있는 종이롤(22)로부터 포장용 종이(12)를 압동롤러(23)와 냉각롤러(24) 사이에 공급하고(포장용 종이 공급 공정), 상기 포장용 종이 공급 공정에서 압동롤러(23)와 냉각롤러(24) 사이에 공급되는 상기 포장용 종이(12) 상에 상기 압출다이스(21)에서 용융된 저밀도/고밀도 폴리에틸렌 혼합물의 용융물을 일정 두께로 압출하여 상기 포장용 종이(12) 상의 용융물을 압동롤러(23)로 융착시키면서 냉각롤러(24)에 의해 냉각시켜서 포장용 종이(12)에 방수층(14)을 융착시키고(방수층 융착공정), 상기 방수층 융착공정에서 상기 포장용 종이(12) 상에 융착된 상기 포장용 종이(12)와 방수층(14)에 오존 분출기(25)에서 오존을 분출하여 소독하여(소독공정), 본 발명의 식품 포장용 방수포장재(10)를 제조한다.Next, after the melting step, the wrapping paper 12 is supplied between the pressing roller 23 and the cooling roller 24 from the paper roll 22 on which the wrapping paper 12 is wound (packaging paper supply step). In the packaging paper supply process, the melt of the low density / high density polyethylene mixture melted in the extrusion die 21 is extruded to a predetermined thickness on the packaging paper 12 supplied between the pressing roller 23 and the cooling roller 24. The melt on the packaging paper 12 is cooled by the cooling roller 24 while fusion bonding with the pressure roller 23 to fuse the waterproof layer 14 to the packaging paper 12 (waterproof layer fusion process), and in the waterproof layer fusion process. The ozone is ejected and disinfected by the ozone ejector 25 to the packaging paper 12 and the waterproof layer 14 fused onto the packaging paper 12 (disinfection step), and the waterproof packaging material 10 for food packaging of the present invention. To prepare.
