Strong growth of unit dose packaging predicted

unit dose packaging

Stick packs and sachets are increasingly popular pack styles in the pharmaceutical industry. They belong to the unit dose category of packaging, defined by its ability to be opened and consumed in one go. The main reason for the popularity of this pack style is better dosage control, which is especially important as ambulant care grows in popularity, requiring patients to self-administer drugs. Stick packs and sachets are a good tool to ensure accurate dosages, leading to increasing demand for these pack styles.


Our innovative packaging system that integrates a stick pack machine and a flow wrapping machine is the right solution to package a wide range of granulates, powders and pellets into stick packs. A seamless interface between the primary and secondary packaging machines maintains output quality, helps to eliminate downtime and ensures the system provides optimal performance.



The system’s primary packaging solution consists of the 10-lane vertical Sigpack RA Stick Pack machine, which allows precise dosing through its patented servo-controlled filling augers at high speeds. An in-line weighing system ensures that each processed stick pack contains the correct amount of product and provides feedback to controls that regulate and adjust dosing levels. These technologies help to save costs by enhancing accuracy, which is essential for companies working with costly products such as pharmaceutical powders.


Subsequently, the filled and sealed stick packs are counted and grouped before being moved through a seamless interface to the secondary packaging unit, the Sigpack HCM horizontal flow wrapper. This machine is capable of wrapping up to 1 000 stick packs per minute, and provides manufacturers with extensive flexibility, as the secondary packaging can be easily modified to contain varying numbers of packs.
