A biodegradable and antibacterial composite paper (SP/CFPLA-6%) was prepared using cellulose, polylactic acid non-woven fabric, and antibacterial short fiber as raw materials through wet papermaking process. Compared with traditional cellulose paper, SP/CFPLA-6% exhibited a decrease of 84.2% in water vapor transmittance, indicating significant hydrophobicity. The tensile strength of SP/CFPLA-6% reached 95.8 MPa, which is more than 70 MPa higher than that of ordinary cellulose paper, demonstrating promising antibacterial activity against Escherichia coli and Staphylococcus aureus. Furthermore, SP/CFPLA-6% showed excellent biodegradability in biodegradation experiments, making it a suitable substitute for traditional non-degradable plastic packaging materials.
Traditional cellulose wrapping paper existing many problems, such as poor barrier, easy water absorption, etc. Herein, cellulose, polylactic acid non-woven fabric and antibacterial short fiber as raw materials, via wet papermaking process, prepared a biodegradable and antibacterial composite paper (SP/CFPLA-6%). Compared with the traditional cellulose paper, the water vapor transmittance of SP/CFPLA-6% decreased by 84.2%, showing obvious hydrophobicity. The tensile strength of SP/CFPLA-6% can reach 95.8 MPa, which is more than 70 MPa higher than that of ordinary cellulose paper, displaying promising antibacterial activity against Escherichia coli and Staphylococcus aureus. Meanwhile, SP/CFPLA-6% shows excellent biodegradability in biodegradation experiments. SP/CFPLA-6% offsets the shortcomings of ordinary cellulose wrapping paper and can be used as a substitute for traditional non-degradable plastic packaging materials.
