The SED-600-4FDB2-B is a specialized four-lane back-seal packaging machine tailored for powder materials, distinguished by its rounded-corner design on the back seal—this feature not only enhances the overall aesthetics of the finished packaging bags but also reduces the risk of sharp edges scratching users or damaging other adjacent packages during storage and transportation.​

As a highly automated packaging solution, this equipment is capable of independently and efficiently carrying out the entire packaging workflow in a fully automatic manner, without the need for excessive manual intervention. The comprehensive process includes several key stages: automatic material feeding (which ensures a continuous and stable supply of powder materials to the metering system, avoiding interruptions caused by manual feeding), precise measuring (to accurately control the weight or volume of powder in each package, meeting strict product quality standards), blanking (smoothly transferring the measured powder into the formed packaging bag), bag forming (shaping the flat film into a sealed bag structure that matches the product specifications), filling (loading the pre-measured powder into the formed bags without spillage), reliable sealing (creating a tight and leak-proof seal on the back of the bags to preserve the freshness and quality of the powder), precise cutting (separating the continuous chain of bags into individual finished products with neat edges), optional coding (adding essential information such as production date, batch number, and expiration date onto the bags, facilitating product traceability and compliance with regulatory requirements), and the creation of easy-tear notches (designing small, user-friendly notches on the bag edges to allow consumers to open the packages quickly and conveniently without the need for additional tools).​

This all-in-one automation design not only significantly improves production efficiency—enabling high-speed packaging of powder products in large quantities—but also minimizes human errors in the packaging process, ensuring consistent product quality across every batch. It is particularly suitable for powder products in industries such as food, pharmaceuticals, cosmetics, and chemicals, where strict packaging standards and high production demands are required.
