The present invention is to provide a packaging container that does not contaminate packaged food while maintaining properties such as sterilization, deodorization, and hygroscopicity. According to one aspect of the present invention, a food packaging container, in which food is packaged, comprises: an inner layer which is in contact with the food and in which a powder composite of charcoal powder and red clay powder attached to each other on the surface by a binder is dispersed in a first polymer resin; an outer layer provided on the outside of the inner layer, wherein the powder composite is dispersed in a second polymer resin; and an intermediate layer provided between the inner layer and the outer layer, wherein the charcoal powder and the red clay powder are each dispersed in a third polymer resin.
본 발명의 일 측면에 따른 식품 포장용기는, 내부에 식품이 포장되는 용기로서, 상기 식품과 접촉되며, 숯분말과 황토분말이 바인더에 의해 표면에서 서로 부착된 분말복합체가 제1고분자수지에 분산되는 내층; 상기 내층의 바깥측에 구비되며, 상기 분말복합체가 제2고분자수지에 분산되는 외층; 및 상기 내층과 상기 외층의 사이에 구비되며, 상기 숯분말 및 상기 황토분말이 각각 제3고분자수지에 분산되는 중간층; 을 포함하는 것을 특징으로 한다.
