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.
