Zusammenfassung:	The present invention relates to a light shielding packaging film containing a natural photosensitizer. More specifically, the film comprises riboflavin, chlorophyll, or myoglobin as the photosensitizer. The film blocks ultraviolet rays and visible rays, and has a significant antibacterial activity. Therefore, the light shielding packaging film can be usefully used as a light shielding packaging material that can keep instinct quality of foods for a long period of time without changes in the quality of the foods, such as destroy of nutrition, acidification, and off-flavor of the foods. 본 발명은 천연 광감제(photosensitizer)를 함유하는 광 차단용 포장 필름에 관한 것으로, 구체적으로 광감제(photosensitizer)인 리보플라빈(riboflavin), 클로로필(Chlorophyll) 또는 미오글로빈(Myoglobin)을 포함하는 필름은 자외선과 가시광선을 차단할 뿐만 아니라, 유의적인 항균활성을 나타내므로, 식품의 영양소 파괴, 산패, 이취 등 식품의 품질 변화없이, 식품 고유의 품질을 오랫동안 유지할 수 있는 광 차단용 식품 포장재로 유용하게 사용될 수 있다.
