The present invention relates to a recyclable packaging container. More specifically, the present invention relates to the packaging container having a structure in which a material of the same class are laminated to enable recycling and formed to reinforce structural robustness of a plastic wrapper. The packaging container in which polyethylene-based sheets are laminated according to the present invention comprises: a body unit in which edges of a front surface sheet layer and a rear surface sheet layer adhere to contain a product; and a glued rim unit. Each of the front surface sheet layer and the rear surface sheet layer may be laminated as an inner layer made of Polyethylene (PE), an outer layer made of High Density Polyethylene (HDPE), and an intermediate layer of a woven structure made of the PE and interposed between the inner layer and the outer layer. 본 발명은 재활용 가능한 포장용기에 관한 것으로서, 더욱 상세하게는 재활용이 가능하도록 동일류 재질을 적층한 구조를 가지며, 비닐 포장지의 구조적 견고함을 보강할 수 있도록 형성된 포장용기에 관한 것이다. 본 발명에 따른 폴리에틸렌 계열 시트를 적층한 포장용기는, 전면 시트층과 후면 시트층의 테두리가 접착되어 제품을 담는 몸체부와 접착된 테두리부로 이루어지고, 상기 전면 시트층과 후면 시트층 각각은 PE(Polyethylene) 재질의 내층, HDPE(High Density Polyethylene) 재질의 외층, 및 상기 내층과 외층 사이에 매개되고 PE 재질의 직조 구조의 중간 매개층으로 적층될 수 있다.
