The invention discloses a modified PBAT material for degradable anti-counterfeiting plastic bags and a preparation method. The modified PBAT material contains raw materials PBAT, PHBV, PPC, modified nano-lignin, diphenylmethane diisocyanate, modified Elo Stone nanotubes and Luo Han Guo extract. The degradable anti-counterfeiting plastic bag with anti-counterfeiting strip obtained by the modified PBAT material prepared by the invention through extrusion, inflation, pulling, printing, winding, bag making and punching not only has the advantages of high relative tear strength of the anti-counterfeiting strip, high tensile strength, and high tensile strength. It has the advantages of high tensile strength, good barrier performance and good flexibility, as well as excellent antibacterial properties, and can be completely degraded into carbon dioxide and water under the action of microorganisms without causing pollution, thus broadening the application field of PBAT degradable materials . |
