a Schematic illustration showing the preparation process of thick paperboard from multiple thin paper plastic sheets by hot pressing and the photographs of multiple paper plastic boards. b Schematic illustration of the plastic bag preparation process using paper plastic. A large number of bags are made of paper plastic. c Compression stress–strain curve of paperboard. d Comparison of Charpy impact toughness of paper plastic with other widely used polymer-based materials. e The oxygen transmission rate of different plastics and paper plastic at 23 °C/90% RH. HDPE high density polyethylene, PP polypropylene, PET polyethylene terephthalate, PVC polyvinyl chloride, PA polyamide, PC polycarbonate, ABS acrylonitrile butadiene styrene. f In vitro cytotoxicity test of paper plastic, including cell morphology and cell viability ratios of 25, 50, 75, and 100% sample extracts. Error bars in d, e, f indicate ± SDs from three measurements. g Skin irritation test of paper plastic. h Skin sensitization test of paper plastic. Source data are provided as a Source Data file.
