The invention discloses a paper-plastic bonding adhesive tape, a plastic compound woven bag and a preparation method. The preparation method of the paper-plastic bonding adhesive tape comprises the following steps: (1) coating the single face of a thin film with a high-barrier material, so as to form a high-barrier material layer; (2) compounding the high-barrier material layer and kraft paper through a bonding material layer; and (3) coating the kraft paper with a hot melt adhesive to form a hot melt adhesive layer. The paper-plastic bonding adhesive tape provided by the invention has a good sealing effect and has waterproof, moisture-proof, mildew-proof, damp-proof, insect-proof, fresh-keeping and sealing effects; the high-barrier material is additionally arranged on a structure of the plastic compound woven bag and the paper-plastic bonding adhesive tape is additionally arranged on a curled edge sealing sewing thread and is used for hotly bonding and sealing, so that the barrier and sealing performances are improved, and a first-layer woven bag and internal packing materials are free of influences of infrared rays, ultraviolet rays and external air, so that a completely sealed state is realized; manual bagging is not needed, so that human resources are saved and the production cost is reduced; and industrial production is easy to realize.
