| 1. Film unwinding | A roll of flexible packaging film is mounted and fed into the machine. | Confirm film direction, roll alignment, web tension, and material compatibility. | Stable feeding helps reduce wrinkles, tracking errors, and material waste. |
| 2. Web guiding and registration | Guiding and registration systems keep the film positioned as it moves through the machine. | Check print-mark detection, film centering, and repeat-length settings when printed film is used. | Accurate positioning supports consistent pouch dimensions and print placement. |
| 3. Pouch forming | The film is folded or shaped into the body of the pouch; a bottom gusset is formed to create the standing base. | Verify fold alignment, gusset depth, and pouch width against the approved specification. | A correctly formed gusset allows the finished pouch to stand when filled. |
| 4. Heat sealing | Heated sealing jaws join the compatible sealant layers to create the pouch seams. | Set and monitor temperature, pressure, and dwell time according to the film supplier’s guidance and production trials. | Consistent sealing conditions help produce strong, uniform seams without damaging the film. |
| 5. Feature insertion (if required) | Optional components, such as a zipper, spout, or valve, are positioned and sealed into the pouch design. | Check component position, seal integrity, and compatibility with the intended filling and use requirements. | Optional features can improve opening, reclosing, dispensing, or product-specific functionality. |
| 6. Cutting and discharge | The formed web is cut into individual pouches, which are then collected for inspection or filling. | Inspect cut position, edges, pouch length, and overall appearance. | Clean, repeatable cutting supports consistent pouch presentation and downstream handling. |
| 7. Quality verification | Samples are checked against the product specification before routine production continues. | Typical checks include dimensions, seal appearance, standing stability, and seal-strength testing where required. | Routine checks help identify process variation and support consistent product quality. |
| Why choose a standing pouch machine? | A purpose-configured machine can combine forming, sealing, and cutting in a coordinated process. It can help standardize pouch production, support optional features, and reduce manual handling. Actual output, pouch formats, and material compatibility depend on the machine configuration, film structure, and operating conditions. |
