Packaging liquids, sauces, and pastes—from water and oils to ketchup and shampoo—involves critical challenges like preventing leaks, achieving filling accuracy with varying viscosities, and ensuring package integrity. Common pain points include messy drips leading to waste and machine contamination, inaccurate volumes causing giveaway or short-weight products, and the inability of standard equipment to handle anything from watery to highly viscous substances without cross-contamination or clogging. For sensitive products like dairy or juices, maintaining hygiene and preventing oxidation are additional key concerns.

The optimal line configuration depends on your product and packaging format. For cost-effective, high-speed production of standard liquid pouches (like water or sauce sachets), a Vertical Form-Fill-Seal (VFFS) machine with a liquid pump filler is ideal. For premium, ready-to-display formats or complex liquids, a premade pouch (like spout pouches or stand-up pouches) or bottle filling line offers superior brand impact and functionality. The core filling technology choice lies between time-pressure/piston fillers for high accuracy with thick pastes and gravity/overflow fillers for clear liquids at very high speeds.
