Universal Pack has been designing and building customized automatic packaging lines for sachets in cartons for more than 60 years.

Our primary packaging machine for sachets feeds our patented counting and stacking unit, which is totally customizable. The unit then transfers the sachets to the secondary packaging machine or inserts them directly into the carton in top-loading configurations with flat blanks. With pre-glued cartons, the cartoning machine performs side loading. Our secondary packaging machines insert the leaflet and close the cartons before carton discharge. In addition, we design specifically designed systems for on edge-placement and multi-level cartoning.

We act as a single supplier of custom-built packaging lines. We design and develop the best solution to integrate the primary packaging machine with the cartoning machine, to support high efficiency. In addition, we can also integrate third-party machinery into our packaging lines: this feature enhances the flexibility of our machines and lines.

Our packaging lines are completely integrated and user-friendly. In fact, only one operator is needed to manage all the processes of our line.

What Do Our Packaging Lines for Sachets in Cartons Include?

All the packaging lines for sachets in cartons designed by Universal Pack include:

  • At least one sachet packaging machine. We configure the machine to produce the sachets with the required dimensions and doses;
  • Counting and stacking unit. We design this section with many customization options depending on the required counts, sachet position, including on edge-placement, and sachet transfers. We provide patented systems to fulfill any request, including on edge placement;
  • Secondary packaging machine. There are multiple solutions, which depend on the type of carton requested, pre-glued or flat-blank.

Sachet Packaging Machines

Universal Pack designs and builds customized solutions for primary packaging. Our machines can produce a wide range of sachets for any king of product.

Each sachet machine can be equipped with the appropriate dosing system, according to your needs and depending on the product characteristics. For this reason, we offer:

  • Auger and basculating-cup systems for powders and granules;
  • Gravimetric and flowmeter systems for liquid or semi-liquid products;
  • Piston pumps for liquid, semi-liquid and viscous products.

Moreover, we design each sachet machine to support high levels of precision, quality and efficiency.

Counting and Stacking Unit

Universal Pack’s patented counting and stacking units are completely customizable. They allow the required number of sachets to be packed into cartons, in the required position. The entire packaging line is flexible, whether in the number of sachets into the carton or their position inside of it.

Upon request, we can provide our counting and stacking units with a specifically-dedicated patented system to turn ‘on edge’ the sachets. Each row of sachets is then transferred into the pockets of the cartoning machine infeed chain.

Moreover, we can provide our on edge-placement system with an additional patented technology installed in the cartoning unit, which allows you to insert sachets on edge in a two-level carton, with or without a separator between the two levels.

Pre-glued cartons

Universal Pack provides cartoning machines for pre-glued cartons equipped with a side-loading system.

Once the counting and stacking unit transfers the sachets to the cartoning station, they are inserted from the side of the carton precisely and efficiently.

This solution can be equipped with key accessories such as dynamic or static checkweighers, leaflet insertion systems with presence check, and tamper-evident labeling machines, ensuring a complete and reliable secondary packaging process.

Flat blank cartons

For flat-blank cartons, Universal Pack provides cartoning machines designed to erect and close boxes starting from flat blanks.

This solution includes two separate units: one dedicated to carton forming and one dedicated to carton closing with hot-melt glue. The system is equipped with a top loading configuration, allowing the counting and stacking unit to insert the sachets into the cartons from above. As with the pre-glued carton solution, the machine can also be equipped with dynamic or static checkweighers, leaflet insertion systems with presence check, and tamper-evident labeling machines.
