상기와 같이 중층에서만 항균 작용을 하는 폴리스틸렌 필름은 항균성이 외층과 내층 모두로 영향이 미치기 때문에 식품을 직접 감싸 포장하는 포장지 및 식품포장 용기의 바닥면에 접착하여 사용을 하게 된다.As described above, the polystyrene film having an antimicrobial effect only in the middle layer has an antimicrobial effect on both the outer layer and the inner layer, so that the polystyrene film is adhered to the bottom surface of the wrapping paper and the food packaging container for wrapping the food directly.

따라서, 상기 폴리스틸렌 필름의 중층에 본발명의 항균성 마스터벳치를 혼합하여 성형하여도 세균들의 번식을 막을 수 있게 된다.Therefore, even if the antimicrobial master beets of the present invention are mixed and molded into the middle layer of the polystyrene film, it is possible to prevent the growth of bacteria.

한편, 상기 폴리스틸렌 필름을 외층과 중층 그리고 내층으로 적층하여 3중 구조의 필름으로 성형시 외층에 항균성 마스터 벳치 분말을 첨가 혼합하여 내층에서만 항균작용이 유발되도록 할수도 있다.Meanwhile, the polystyrene film may be laminated in an outer layer, a middle layer and an inner layer to add and mix an antimicrobial master batch powder to the outer layer when forming a triple-structured film so that the antimicrobial action may be induced only in the inner layer.

즉, 상기 폴리스틸렌 필름의 내층은 폴리스틸렌(Polystyrene) 70-85중량%와, 스틸렌-부타디엔 공중합체(Styrene-Butadiene Copolymer) 10-20중량%와, 고강도 폴리스틸렌(High Impact Polystyrene) 1-5중량%와, 항균성 마스터벳치(Anti-Bacteria Master Batch)5-15중량%의 비율로 혼합시킨다.That is, the inner layer of the polystyrene film is 70-85% by weight of polystyrene, 10-20% by weight of styrene-butadiene copolymer, 1-5% by weight of high impact polystyrene, , Anti-Bacteria Master Batch (Anti-Bacteria Master Batch) 5-15% by weight of the mixture is mixed.

그리고, 상기의 비율로 혼합된 내층을 통상적인 중층 및 내층과 함께 용융, 압출방사시키면 항균성을 가진 3중구조의 폴리스틸렌 필름을 얻을 수 있게 된다.In addition, when the inner layer mixed at the above ratio is melted and extruded together with the conventional middle layer and the inner layer, it is possible to obtain a polystyrene film having a triple structure having antimicrobial properties.

상기와 같이 내층에서만 항균작용을 하는 폴리스틸렌 필름은 식품포장 용기의 바닥면에 접착하여 사용을 하게 된다.As described above, the polystyrene film having an antibacterial effect only on the inner layer is used by bonding to the bottom surface of the food packaging container.

즉, 상기 3중구조의 폴리스틸렌 필름의 외층은 용기의 바닥면과 접촉하면서 접착되도록 하고 항균성이 있는 내층을 포장되는 내용물과 접촉하도록 함으로서 세균들의 번식을 막을 수 있게 된다.That is, the outer layer of the triple structure of the polystyrene film is in contact with the bottom surface of the container to be adhered, and the antimicrobial inner layer to be in contact with the packaged contents to prevent the growth of bacteria.

또한, 상기 폴리스틸렌 필름을 외층과 내층으로 적층하여 2중 구조의 필름으로 성형시 외층 및 내층에 항균성 마스터 벳치 분말을 첨가 혼합하여 내,외층에서 모두에서 항균작용이 유발되도록 할수도 있다.In addition, the polystyrene film may be laminated in an outer layer and an inner layer to add and mix an antimicrobial master beech powder in the outer layer and the inner layer when forming a double-structured film, so that the antimicrobial action may be induced in both the inner and outer layers.

즉, 상기 2중 구조의 폴리스틸렌 필름의 외층은 폴리스틸렌(Polystyrene) 70-85중량%와, 스틸렌-부타디엔 공중합체(Styrene-Butadiene Copolymer)10-20중량%와, 고강도 폴리스틸렌(High Impact Polystyrene) 1-5중량%와, 항균성 마스터 벳치(Anti-Bacteria Master Batch)3-15중량%의 비율로 혼합시킨다.That is, the outer layer of the polystyrene film of the double structure is 70-85% by weight of polystyrene, 10-20% by weight of styrene-butadiene copolymer, and high-strength polystyrene (High Impact Polystyrene) 1- 5 wt% and 3-15 wt% Anti-Bacteria Master Batch are mixed.

그리고, 상기 2중 구조의 폴리스틸렌 필름의 내층도 폴리스틸렌(Polystyrene)70-85중량%와, 스틸렌-부타디엔 공중합체(Styrene-Butadiene Copolymer)10-20중량%와, 고강도 폴리스틸렌(High Impact Polystyrene) 1-5중량%와, 항균성 마스터벳치(Anti-Bacteria Master Batch)3-15중량%의 비율로 혼합시킨다.In addition, the inner layer of the double structured polystyrene film is also 70-85 wt% of polystyrene, 10-20 wt% of styrene-butadiene copolymer, and high-strength polystyrene 1- 5% by weight and 3-15% by weight of Anti-Bacteria Master Batch (Anti-Bacteria Master Batch) is mixed.

그리고, 상기의 비율로 혼합된 외층 및 내층을 용융, 압출방사시키면 항균성을 가진 2중구조의 폴리스틸렌 필름을 얻을 수 있게 된다.Then, by melting and extruding the outer layer and the inner layer mixed at the above ratio, it is possible to obtain a polystyrene film having a double structure having antimicrobial properties.

상기와 같이 내,외층에서 모두에서 항균작용을 하는 폴리스틸렌 필름은 항균성이 외층과 내층 모두에서 발생하기 때문에 식품을 직접 감싸 포장하는 포장지 및 식품포장 용기의 바닥면에 접착하여 사용을 하게 된다.As described above, the polystyrene film having an antimicrobial action in both the inner and outer layers is used to adhere to the bottom surface of a wrapping paper and a food packaging container that directly wraps the food because the antimicrobial activity occurs in both the outer and inner layers.

따라서, 상기 2중으로된 폴리스틸렌 필름에 본발명의 항균성 마스터 벳치를 혼합하여 성형하여도 세균들의 번식을 막을 수 있게 된다.Therefore, even when molded by mixing the antimicrobial master batch of the present invention to the double polystyrene film it is possible to prevent the growth of bacteria.

이와같이된 본발명은 폴리스틸렌의 용융액에 향균성을 가진 항균 마스터벳치 분말을 첨가 혼합하여 폴리스틸렌 필름을 성형함으로서, 폴리스틸렌 필름의 표면 및 이면으로 세균,곰팡이,기타 바이러스 등이 증식되는 것을 방지하여 폴리스틸렌 필름으로 포장된 식품이 변질되는 것을 막는 동시에 악취의 발생을 막아 위생적인 유통이 가능하도록 하고 식품의 유통기간을 늘릴 수 있는 유용한 효과를 갖는다.Thus, the present invention forms a polystyrene film by adding and mixing an antimicrobial masterbatch powder having antimicrobial effect to the melt of the polystyrene, thereby preventing the growth of bacteria, mold, and other viruses on the surface and the back of the polystyrene film to form a polystyrene film. It prevents the packaged foods from being deteriorated and at the same time prevents the occurrence of odors, thus enabling hygienic distribution and extending the shelf life of the foods.
