The automatic bag-in-bag packing line combines multi-head weighing, VFFS pouch forming, pouch counting and secondary bagging in one seamless flow. Bulk products are weighed into small pouches, then collected, counted and packed into large outer bags.
The multi-head weigher weighs and doses portions accurately, while the cleated belt conveyor transfers products between units at a synchronized speed. The VFFS machine forms, fills and seals pouches from film roll; the secondary bagging machine then counts, arranges and loads them into big outer bags for sealing and discharge.
High-precision load cells and servo-driven control deliver accurate counting and consistent bag filling, with adjustable bag size and packing speed. Food-grade 304 / 316 stainless steel, interchangeable sealing jaws and cutting knives, and an anti-slip PU cleated belt ensure hygienic, flexible and stable operation. Siemens HMI, Autonics photoelectric switch, igus sleeves, Delixi breaker and Hengfu power supply complete the robust construction.
Suitable for grains, rice, beans, nuts, seeds, candies, chocolate, biscuits, cookies, snacks and dried fruit, with various pouch and outer bag types. Fine powders require an optional screw dosing unit.
