Doypack Pre-made Pouch Filling Machine: Filling Process and Material Adaptation Analysis

The Doypack pre-made pouch filling machine is special equipment dedicated to quantitative filling for stand-up pouches. It focuses on accurate filling after pouch opening and can be linked with various pre-made pouch packaging main machines, serving as the core metering equipment of stand-up pouch packaging lines. The machine optimizes filling processes according to physical properties of different materials to meet demands of refined packaging production.

For powder materials, the machine adopts a closed screw filling structure to reduce dust emission. For pastes and high-viscosity sauces, a piston filling structure is used to minimize material adhesion and uneven discharging. For granular materials, weighing filling modules are equipped to guarantee metering consistency. The whole filling system can be freely configured according to product requirements to realize flexible production of multiple product categories.

The filling head adopts quick-release design for easy disassembly, cleaning and sterilization, preventing cross contamination of different materials. The filling speed can be steplessly adjusted to suit both low-speed precision filling and high-speed mass production. It is applicable to stand-up pouch filling in food, health, pet food and other industries.
