摘要：
The present invention relates to a manufacturing method of an antibacterial polyethylene packaging film for improving storability of fruits and vegetables and a packaging film by the same, and more specifically, to a manufacturing method of an antibacterial polyethylene packaging film for improving storability of fruits and vegetables and an antibacterial polyethylene packaging film which is manufactured by melting a polyethylene resin (PE) mixed with bactericide-N at a concentration of 0.5% (w/w) and nylon at a high temperature to compress the polyethylene resin and the nylon to position the polyethylene resin on an inner surface thereof and position the nylon on an outer surface thereof. The antibacterial polyethylene packaging film suppresses proliferation of low-temperature microorganisms and contact with air more effectively than a case where a film is not used at all for packaging and a case where low-density polyethylene (LDPE) is used by bactericide-N, an antibacterial material, mixed in a polyethylene resin and nylon attached to the outside of the film to lower a decomposition rate of packaged fruits and vegetables, suppress softening, reduce hardness, water content, and weight preservation rates much more slowly, and continuously maintain excellent functions of color, taste, and texture to consequently increase storage time at least five times in comparison to a case where fruits and vegetables are not packaged by a film. Therefore, the present invention is very useful in the food storage industry.COPYRIGHT KIPO 2018본 발명은 과채류의 저장성 향상을 위한 항균성 폴리에틸렌 포장필름의 제조방법 및 그 포장필름에 관한 것으로, 더욱 상세하게는, 과채류 저장성 향상을 위한 항균성 폴리에틸렌 포장필름의 제조방법에 있어서, 박테사이드 엔(Bactecide-N)을0.5%(w/w) 농도로 혼합한 폴리에틸렌 수지(polyethylene resin: PE)가 그 내부면에, 나일론이 그 외부면에 위치하도록, 이들을 고온에서 녹여 압착하여 부착시켜 제조하는 것을 특징으로 하는 항균성 폴리에틸렌 포장필름에 관한 것이다.본 발명의 항균성 폴리에틸렌 포장필름은, 폴리에틸렌 수지에 혼합된 항균성 물질 박테사이드 엔(Bactecide N) 및 필름의 외부에 부착된 나일론에 의해, 필름으로 전혀 포장하지 않은 경우 및 일반 저밀도 폴리에틸렌(Low density polyethylene:LDPE) 필름을 사용한 경우보다 저온
