Manufacturer of square bottom valve bag production equipment: Core technology and industry outlook

Square-bottom valve bags, as an important form of modern industrial packaging, are widely used in building materials, chemicals, food, and pharmaceutical industries. Their unique structural design ensures both the sealing and stability of the packaging, while also improving filling efficiency and transportation safety. As a manufacturer of square-bottom valve bag production equipment, we are keenly aware of our crucial role in the industry chain—not only do we need to provide efficient and stable production equipment, but we must also continuously drive technological innovation and industry progress.

The core technology of square bottom valve bag production equipment

The production equipment for square-bottom valve bags is a complex system integrating mechanical engineering, automation control, and materials science. A complete production line typically includes a substrate unwinding device, a printing system, a folding and forming mechanism, a bottom valve forming unit, a gluing system, a precise bottom folding device, a heating and pressurizing curing unit, and a finished product counting and stacking output section. The technical precision of each step directly affects the quality of the final product.

During the substrate processing stage, the equipment needs to be adaptable to various materials such as kraft paper, PE-coated paper, and woven fabric, ensuring a smooth and wrinkle-free substrate through a constant tension control system. The printing system employs high-precision servo drives to achieve accurate registration of color patterns, meeting the visual marketing needs of brand owners. Valve nozzle formation is a technical challenge, requiring a specially designed folding device and paper guiding system to ensure a uniform valve nozzle structure and guarantee smooth subsequent filling operations.

The folding and bonding of the bag bottom are crucial processes that determine the bag's load-bearing capacity. Advanced equipment uses a multi-axis robotic arm in conjunction with a vision positioning system to achieve precise lamination of the four layers of material at the bag bottom. The hot melt adhesive coating system requires precise control of the adhesive amount and temperature based on the material characteristics; too high a temperature will cause the material to char, while too low a temperature will affect the bonding strength. The final pressure curing stage uses a PLC-controlled pressure curve to ensure that the bonded area achieves optimal physical properties.
