Universal Pack designs and builds a wide range of custom-built stick pack packaging machines. Specifically, our vertical intermittent-motion stick pack machines can handle low-viscosity and free-flowing liquids with high dosing accuracy thanks to our gravimetric and flowmeter dosing systems.
On one hand, the gravimetric perfectly works with thinner liquid products. This dosing solution uses the gravity principle to let the liquid flow into the stick packs. The opening time of the peristaltic closure determines the dose into the stick packs. The peristaltic closure also allows the stick packs already filled to be sealed, by blocking the flowing of the product. To summarize, the gravimetric is characterized by minimum maintenance, high flexibility, good precision and ease of cleaning.
On the other hand, the flowmeter is suitable to dose semi-liquid and viscous products, with micrometrical adjustment of the dose. The difference between flowmeter and gravimetric results in the working principle. While the gravimetric is based on the opening and closing time of the peristaltic closure, the flowmeter calculates the mass of the flowing liquid through sensors.
In both cases, we design dosing nozzles and cleaning procedures to suit the characteristics of your product.
The company’s patented design to insert and fold sealing film around forming tubes represents one of the advantages for achieving maximum efficiency and reliability. Thanks to this, Universal Pack machines are known worldwide.
Our stick pack machines for liquids are a compact solution combining the highest output with a small footprint. These solutions include many advantages such as great dose accuracy, minor wrapping material waste, easy handling and cleaning. Moreover, our user-friendly and modular stick pack machines allow our customers to reduce downtime and fulfill their increasingly high production demands.
