Stick Pack Packing Machine

Multi Lane Liquid Stick Packaging Machine

Breakthroughs in Our Multi-Lane Liquid Stick Pack Line to Stop Leaks and Maximize OEE

Introduction: The High-Stakes Shift to Liquid Single-Dose Packaging

In pharmaceutical, nutraceutical, and high-volume food processing industries, the market demand for single-dose liquid packaging has reached an all-time high. Consumers across Europe and North America heavily favor the portable convenience of sleek, single-serving stick packs. However, migrating your production line from traditional bottles or rigid containers to flexible film requires a major leap in engineering control.

For operation managers, the transition to liquid flexible packaging is often plagued by costly headaches: product leakage, inconsistent sealing, dosing inaccuracies, and agonizingly slow changeover cycles. When dealing with premium liquid formulas, active pharmaceutical ingredients (APIs), or viscous food pastes, even a tiny variation in your machinery can result in extensive product waste, strict regulatory non-compliance, and devastating downtime.

1. Decoupling the Liquid Stick Pack Machine: Engineering Rigor Over Common Mechanical Layouts

A generic stick packing machine or standard form-fill-seal system is typically designed around mechanical linkages and basic gravity-fed funnels. While this setup works for free-flowing powders, it fails completely when subjected to the physical properties of liquids. High-surface-tension fluids, sticky pastes, and dense emulsions exhibit erratic behaviors during high-speed multi-lane filling. Capillary action can cause product trailing across the sealing area, which compromises the film laminate and causes chronic leaks down the line.

To prevent seal contamination, a high-performance liquid stick pack machine must master the exact timing between liquid delivery and horizontal film advancement. The Rich Packing liquid line controls this process through a closed-loop electronic synchronization network. By isolating the pump actuation from the vertical film pulling cycle, our machinery ensures that the liquid dose is injected cleanly into the center of the formed tube, with zero splashback or residual trailing.

Furthermore, our heavy-duty platform replaces traditional unified drive shafts with decentralized, synchronized servo drives. This architecture allows operators to calibrate each lane independently through the central HMI, providing absolute mechanical repeatability across micro-dosing applications.
