A Multihead Weighing Packing Machine is a Vertical Form Fill Seal (VFFS) system that uses a multi-head combination scale to weigh products with high accuracy before dropping them into bags.

🔹 How it works step by step:

  • Product feeding – Product is fed to the top of the multi-head weigher via conveyor or feeder.
  • Weighing hoppers – The product is distributed into multiple weighing hoppers (commonly 10–20 heads).
  • Combination calculation – The system calculates the best combination of hoppers that matches the target weight.
  • Discharge – The selected hoppers release product into the forming tube.
  • Bag forming, sealing, cutting – The VFFS system completes the bag packaging.

🔹 Why use a multi-head weigher?

  • High accuracy – typically within ±0.1–0.5 g.
  • Fast speed – handles dozens to hundreds of packs per minute.
  • Flexibility – can weigh irregular, sticky, or fragile products.
  • Reduced giveaway – less product waste compared to volumetric systems.

🔹 Best suited for:

  • High-value snacks (nuts, dried fruit, candy).
  • Frozen food where accurate weight compliance is required.
  • Irregular or fragile products that cannot be measured by cups.

🔹 Limitations to consider:

  • Higher investment cost than volumetric cups.
  • Requires more maintenance (hoppers, sensors, cleaning).
  • Larger footprint compared to simpler filling systems.

👉 In summary: A Multihead Weighing Packing Machine is the best choice for manufacturers prioritizing accuracy, reduced waste, and premium product presentation.
