It has the advantages of high production efficiency, high degree of automation, stable product quality, etc., and can meet the packaging needs of different types of products. With the continuous development of the packaging industry, the requirements for packaging materials are getting higher and higher. As an environmentally friendly, lightweight and easy-to-process packaging material, non-PVC film soft bags are gradually favored by the market.

[0003] Film feeding is one of the important links in the tail-filling non-PVC film soft bag production line. It mainly feeds the plastic film into the filling and sealing equipment according to production requirements to ensure the smooth progress of the production process. In this process, the accuracy and stability of film feeding directly affect the quality of packaging materials and production efficiency.

[0004] If the non-PVC film curls and rolls up, it will cause the packaging material to be uneven, affecting the appearance and quality of the product. If the curling and rolling are too serious, it may cause the packaging material to break or break, affecting the safety and sealing of the product. Curling and rolling will also affect the efficiency of the production line. Therefore, we propose a tail-filling non-PVC film soft bag film feeding, clamping and pulling device to ensure the smooth progress of the production process. Utility Model Content
