Industrial VFFS Vertical Form Fill Seal

Work backwards from peak bags per minute, not averages, because the bagger is sized for the rush. The range runs from 30 bags per minute on an entry machine to 200 on an industrial high-speed unit. The filler sets the honest ceiling: an auger for powder, multi-head weigher for granules, liquid pump, or cup filler, each with its own speed limit.

PE, PP, laminated films, metalized structures, and paper-film laminates all run on the same chassis with the right forming tube and seal parameters. Fully recyclable mono-material PE is workable but seals differently from laminates, so film trials matter. Bag width range is 30 to 300mm and length 50 to 500mm, which covers most snack and frozen formats.

Bag style comes from the forming tube and jaw set, so pillow bags are standard, and gusseted, flat-bottom, quad-seal, and doy-pack styles need the corresponding kit. A format change is tube swap, jaw change, and parameter recall, typically under half a day for a trained crew with the kit on hand. Nitrogen flush settings carry across styles.

Wrinkles and leaks usually trace to three points. Film tension and centering off makes one seal leg longer than the other. Wrong temperature or dwell for the actual film structure causes weak seals that pass dry and fail wet. Product contamination in the seal area, especially powder from an aggressive fill, keeps layers from fusing. The weekly forming tube clean prevents most of it.

Seal jaw strips or coatings, cutting knives, forming tube wear parts, and the heater and temperature control cards. Weekly forming tube cleaning and monthly seal jaw inspection catch wear before quality drifts. Jaw and knife sets are consumables measured in months of production. We ship a recommended spares list with the machine so the first order is a checklist, not a scramble.

Yes. We provide installation and commissioning support, and 12 months of after-sales service, including spare parts help and technical response.
