Weighing, Forming, Filling & Sealing Process

The machine integrates the complete bag packing workflow: precise weighing of rice, sugar, salt, flour or other granular and powdery products, automatic bag forming from film, accurate filling, and firm sealing. The multi-function packaging machine handles different bag types — 3-side seal and back seal — and switches between stand-up pouches, flat bags and film pouches, giving producers one machine for multiple packaging formats.

Control & Operation

A PLC-based control system manages the whole packing cycle, including weighing accuracy, filling volume and sealing parameters. Operators can adjust settings to match different products and bag sizes, while the customizable speed options allow the machine to be tuned to your production rhythm — from 5 bags/min for small batches up to 80 bags/min for high-volume lines.
