Each Synthesis Synthesis BU4T/BU4TR Complete automatic packaging line is  entirely designed and constructed by Universal Pack.
Thanks to our experience gained in 50 years in the packaging industry we are able to combine even complex packaging processes on a single line.
Universal Pack Synthesis complete automatic packaging Lines are individually custom-built, whether for primary or secondary packaging, and may include integration of all auxiliary units guaranteeing the highest efficiency together with the most compact machine layout, perfectly in line with Universal Pack traditional concepts.
The end result is that a cutting edge complete packaging line can be managed by a single operator, thanks to its user friendly and compact design.
Simplicity, endurance and quick size changeover are the strength and the key of success of Universal Pack machines and lines, guaranteeing at the same time the highest efficiency as well as simplified maintenance and improved user-friendliness of the machine itself. 
  • Product distribution and infeed as well as primary and secondary packaging operations are based on a standardized operating architecture.

    System interfaces are harmonized, thus ensuring a smooth production process for optimal use of space, productivity and availability. We create the perfect solution for you.

    Each  line is composed by Serie GAMMA  sachets machine linked in line to collating and stacking units Serie R80 and to Serie DELTA Cartoning Machines.

    The result is a line that fulfills all current requirements for 4 seal side sachet primary and secondary  packging , such as:

    • High speed
    • Maximum availability
    • Reliability
    • Reduced foot print tahnks to its optimized compact layout
    • Endurance

Automatic vertical packaging machines for all needs: since 50 years we are bringing innovation to the world of single-dose packaging, producing high-performance automatic vertical bagging machines which we can adjust to the costumer’s specific needs. Besides single-serve packaging machines, our primary and secondary products line can satisfy the most peculiar packaging needs, producing 4 side heat-sealed bags, shaped sachets, stick-packs and hollow-punch cases. We are always in absolute control of the situation, as design, production and assembly of each packaging machine take place in our company.

Our packaging machines are designed and manufactured entirely by us, therefore we are able to produce customised machines, packaging lines and solutions for every commodity sector. In addition, it is possible to edit operational parameters via touch-screen display, with no need for mechanical intervention. Overall, all the operating parameters are electronically managed and thus they can be edited without interrupting the production phase. Furthermore, all our automatic vertical packaging machines were designed and tested to work 24/7.

Every year we invest in research and development in the field of single-dose packaging, so that our automatic vertical packaging machines can become even more trustworthy and efficient. This has allowed us to manufacture productive machines which remain excellent even after 30 years of use. Their reliability is guaranteed by our company’s factory, which produces over the 80% of the machines’ components, and strict quality control. In order to adapt the production of automatic vertical packaging machines to the market needs, we implement power supply groups to allow the existing packaging system to elaborate complementary products.
