The invention belongs to the technical field of plastic packaging and discloses an anti-counterfeiting plastic weaving and composite packaging method. According to the method, flat filaments as the basic material are woven by a circular knitting unit according to a designated type, a woven yardage roll with the effective width ranging from 450 mm to 700 mm is produced, patterns, characters and the like are printed by a color printing unit on a BOPP (biaxially-oriented polypropylene) film or other basic materials such as a BOPET ((biaxially-oriented polyethylene terephthalate) film, an aluminum laminated film and the like according to requirements of customers, a hot soft printing device can print various fixed information or data variable information such as two-dimensional codes, bar codes, numbers, Chinese characters, an operation mode adopts computer control, anti-counterfeiting data are transmitted and printed in real time, a film-shaped adherend is extruded by a plastic extruding and laminating unit, the woven fabric roll and a color film are laminated together, and the stripping force is higher than 3N/30 mm. The method aims to develop a novel plastic composite packaging bag with anti-counterfeiting performance and eliminate the loophole in a counterfeited fertilizer packaging link.
