Technical Field

[0002] Plastic packaging bags are made of plastic as raw material and are used to produce packaging bags for various daily necessities. They are widely used in daily life and industrial production. Plastic packaging bags are generally made of two plastic films, the front and the back, which are heat-sealed; In the production process of plastic packaging bags, edge ironing and labeling are two important processes. At present, these two processes are mostly carried out separately. At present, plastic packaging production and processing plants usually use independent edge ironing machines and labeling machines for separate processing, and transfer products from one device to another for processing by manual or conveying devices; However, this method of processing by multiple devices will result in low production efficiency, and multiple devices occupy a large area. After processing on one device, the product is transferred to another device for further processing, and the labor cost of manual transfer increases. Moreover, the transfer between processing steps may cause problems such as product damage. Therefore, further improvements can be made. Summary of the invention
