APPLICATIONS
It is suitable for a wide range of liquid and semi-liquid products, as the filling system can be configured based on material characteristics, including:
- Water-based liquids
- Beverage concentrates
- Syrups
- Functional drinks
- Gel or semi-liquid products
For specialized applications such as long-format frozen liquid products, this system can be adapted to produce extended sachets with reinforced sealing structures.
For example, ice pop products (long sachet up to 200–250mm) require enhanced film stability and sealing strength.

In addition to standard sachets, the machine can also be configured for irregular-shaped 4-side seal sachets, which are widely used in cosmetic, gel, and premium liquid packaging.
