[0002] Packaging bags make it easy to transport and store goods during the production and circulation process. They are widely used in daily life and industrial production. Packaging bags are one of the most commonly used items in production. Existing packaging bags are generally produced with kraft paper as the outer layer and woven cloth as the inner layer. During processing, PP material needs to be hot-melted and added between kraft paper and woven cloth for compounding.

[0003] The prior art, such as the invention patent with publication number CN111846574A and titled "An Environmentally Friendly Center-Seal Molded Multilayer Packaging Bag and Its Production Process", includes a bag body, which includes an inner layer, a first middle layer, a second middle layer, and an outer layer connected in sequence, wherein the inner layer is a plastic woven cloth layer, the first middle layer is an adhesive coating layer, the second middle layer is a PP type film printed body layer, and the outer layer is an anti-slip coating layer.

[0004] When processing and compounding this type of packaging bag, it is generally processed by applying heated and melted PP material on the woven cloth and then compounding it with kraft paper. Traditional packaging bag bonding equipment is generally manual foot-operated bonding, which is time-consuming and labor-intensive for workers to operate, with a low degree of automation, resulting in low production efficiency.
