Abstract

In recent years, there has been a growing concern about the environmental impact of plastics due to the rapid growth of packaging and disposable products. Among them, food packaging films are mostly made of synthetic polymers, which can be accumulated in natural environments and exacerbate environmental pollution. In this study, an eco-friendly food packaging film was prepared using poly(3-hydroxybutyrate-co-3-hydroxyvalerate) copolymer, a biodegradable aliphatic polyester produced from microorganisms. The film was fabricated using a simple hot-press process and dip-coated with tannic acid to provide antioxidant and antimicrobial properties that can prevent the food spoilage. The potential of the film to be used as a functional food packaging film was confirmed by packaging actual food products.


최근, 포장용기 및 일회용품의 급증으로 인해 플라스틱에 의한 환경오염의 우려가 커지고 있다. 식품 포장용 필름은 대부분 합성고분자로 제조되어 자연환경에 축적됨으로써 환경오염을 더욱 악화시킬 수 있다. 본 연구에서는 미생물로부터 생산되는 생분해성 지방족 폴리에스터인 poly(3-hydroxybutyrate-co-3-hydroxyvalerate) 공중합체를 사용하여 환경친화적인 식품 포장용 필름을 제조하였다. 필름은 간단한 핫프레스 공정을 통해 제조되었으며, 식품 부패 방지에 도움이 될 수 있는 항산화 및 항균 특성 부여를 위해 탄닌산(tannic acid)의 딥 코팅을 수행하였다. 또한, 제조된 필름을 통해 실제 식품에 대한 포장을 진행함으로써 기능성 식품 포장용 필름으로 사용될 수 있는 잠재력을 확인하였다.
