Paper-like packaging product containing plastic corrugated plate structure and preparation method of paper-like packaging product

The invention provides a paper-like packaging product containing a plastic corrugated plate structure and a preparation method of the paper-like packaging product, the paper-like packaging product containing the plastic corrugated plate structure comprises a supporting framework layer, the supporting framework layer is a corrugated plate, and the supporting framework layer is made of plastic; a first supporting layer and a second supporting layer are arranged on the two surfaces of the supporting framework layer, the first supporting layer and the second supporting layer are made of plastics, and the first supporting layer and the second supporting layer are compounded with the supporting framework layer in a welding mode. By the adoption of the technical scheme, paper boards are replaced with plastic, and the plastic packaging box has the same or better strength and protection capacity as a paper packaging box, is lighter in weight and further has the waterproof capacity. And secondly, the plastic has certai
