Viscous Liquid Filling Machines

Liquid filling machines are also referred to as liquid packaging machines, liquid dosing machines, or liquid filler-sealers. In the context of viscous products, terms like paste filling machines, sauce packaging machines, and cream/gel fillers are also commonly used depending on the product viscosity and packaging format.

Common methods include piston filling (for high-viscosity products), gravity filling, pump filling (peristaltic or gear pump), and pressure/vacuum filling. Viscous liquid filling machines typically rely on piston or pump-based systems combined with heated or agitated hoppers to maintain consistent flow and accurate dosing during the fill cycle.

These machines are designed to fill sauces, condiments, pastes, creams, gels, lotions, adhesives, and lubricants. Depending on the machine type, filling volumes range from as little as 1ml for sachets up to 3000ml for larger paste and liquid formats, accommodating both small-batch and industrial-scale production.

VFFS (Vertical Form Fill Seal) machines form a flexible pouch or sachet from roll film, fill it, and seal it in one continuous process, ideal for single-serve and bulk pouch formats. Tube filling machines instead fill pre-made plastic, laminated, or aluminum tubes and seal the open end using heat, ultrasonic, or fold/crimp methods, commonly used for creams and gels.

Yes. Models featured in this category use 316L or food-grade stainless steel construction and are GMP-compliant, making them suitable for pharmaceutical ointments, nutraceutical pastes, and food products such as sauces and condiments. Several models also carry CE certification for use in European markets.

Fill volumes range from as low as 1ml in compact sachet formats up to 3000ml for larger paste and liquid tube fillers. Speeds vary by model, from 10-30 tubes per minute on semi-automatic tabletop units to up to 140 bags per minute on high-speed automatic VFFS production sets.
