Sachet Machine for Liquids

Universal Pack designs and builds a wide range of custom-built sachet packaging machines. Specifically, our vertical continuous-motion sachet machines can handle low-viscosity and free flowing liquids with high dosing accuracy thanks to our gravimetric and flowmeter dosing systems.

Which dosing systems are suitable for packaging liquids?

On one hand, gravimetric perfectly works with thinner liquid products. This dosing solution uses the gravity principle to let the liquid flow into the sachets. The opening time of the peristaltic closure determines the dose into the sachets. The peristaltic closure also allows the sachets already filled to be sealed, by blocking the flowing of the product. To summarize, gravimetric is characterized by minimum maintenance, high flexibility, compromising precision and ease of cleaning.

On the other hand, 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 gravimetric is based on the opening and closing time of the peristaltic closure, 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.

Our sachet machines for liquids guarantee 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 sachet machines allow our customers to reduce downtime and fulfill their increasingly high production demands.

Universal Pack sachet machines are specifically-dedicated to single-dose packages. For example, we can dose from 0,1 up to 200 ml of liquids, semi-liquids and low-viscosity products in a sachet, the dimensions of which vary depending on your marketing goals, nature of the products and production requirements.

Moreover, we provide you with the possibility to easily integrate your sachet pack machine in a Universal Pack packaging line for cartoning. Our lines allow you to inserrt from 1 up to 100 or more sachets in the same carton. We have developed patented counting units for any amount of packages to be picked up and put into cartons. In recent years, our philosophy is to save as much material and product as possible, both for economic and environmental sustainability.

Universal Pack sachet packaging machines for liquids can process all typical heat-sealable composite films, for example: PAP-ALU-PE (paper – aluminum – polyethylene), PET-ALU-PE (polyethene terephthalate – aluminium – polyethene) and cold sealable materials. Our machines can also package sustainable laminates such as PP (polypropylene), PLA (polylactic acid), PAP (paper), Bio-PE (bio-based polyethene), and more on request.

Our non-stop research in reducing the packaging industry carbon footprint resulted in streamlined machinery design for packing recycled, recyclable and compostable laminates. LCA (Life Cycle Assessment) is used to measure the environmental impact of our products and identify optimal ways to reduce it. It is a 360° analysis that goes beyond the mere packaging produced and involves every step of the packaging machinery production process. We develop our solutions shoulder-to-shoulder with the main global film suppliers and test them in agreement with major multinational companies in order to provide them with a turnkey solution able to produce eco-packages.
