Choosing the proper type of multihead weigher might mean the difference between having trouble with production bottlenecks and running your packaging line smoothly and profitably. If you want to get the most out of your investment, you need to know the pros and cons of different multihead weigher setups, whether you’re using VFFS machines, pouch packing systems, or tray packaging lines.
Why it matters to choose the right type of multihead weigher?
- Efficiency of production: Using the wrong type of weigher can cut throughput by 15–25%.
- The quality of the product: Improper handling can hurt high-end products.
- Costs of doing business: A bad choice raises the giveaway by 0.5% to 1.2%.
- Putting systems together: Problems with compatibility cause frequent downtime.
The reality is that not all multihead weighers are created equal. Each type brings unique strengths to your packaging operation, and selecting the wrong configuration can lead to:
- Reduced throughput capacity
- Increased product giveaway
- Frequent maintenance issues
- Integration compatibility problems

Frequently Asked Questions
Q: What’s the main difference between rotary and linear multihead weighers? A: Rotary weighers offer maximum speed (120+ weighments/minute) with compact design, while linear weighers provide flexibility and easier maintenance with moderate speed (30-80 weighments/minute).
Q: When should I choose belt linear weighers over standard linear systems? A: Belt linear weighers are ideal for sticky, fragile, or premium products where gentle handling preserves product integrity and appearance.
Q: How do multihead weighers integrate with VFFS machines? A: All multihead weigher types integrate with VFFS systems through synchronized controls, with rotary weighers optimal for high-speed operations and linear systems better for flexible production.
Q: What accuracy can I expect from modern multihead weighers? A: Modern multihead weighers achieve ±0.5g accuracy consistently, with advanced models reaching even higher precision depending on product characteristics.
Q: Are multihead weighers suitable for non-food applications? A: Yes, multihead weighers excel in non-food applications including pharmaceuticals, hardware, pet products, and industrial components with appropriate configuration selection.
