In modern manufacturing, secondary packaging is no longer a manual activity. When primary pouches come out of VFFS or HFFS machines at high speed, they must be grouped, aligned, and bundled properly before moving to dispatch or case packing. This is where a Pouch Bundling Machine plays a critical role.
Understanding how a pouch bundling machine works helps production managers and plant heads make better buying decisions and improve packaging line efficiency.
Step 1: Infeed – Receiving Pouches from Primary Packaging
The process starts when individual pouches arrive from the primary packaging machine through a conveyor system. These pouches can contain snacks, powders, spices, detergents, or FMCG products.
The bundling machine receives these pouches continuously and prepares them for grouping. A smooth and stable infeed is important to avoid product overlapping or misalignment.
In automated systems like Infinity’s IBP-120, the infeed is designed to handle high-speed production lines without disturbing pouch orientation.
Step 2: Collation – Arranging Pouches in Matrix Format
After entering the machine, pouches move into the collation section. This is the heart of the pouch bundling process.
Here, pouches are arranged into a pre-set matrix format such as 2x5, 3x4, or any desired configuration depending on customer requirements. Servo-controlled systems ensure accurate counting and placement.
The machine forms the required bundle structure automatically. This eliminates manual grouping errors and ensures every secondary pack contains the correct number of pouches.
Accurate matrix formation improves downstream processes like shrink wrapping, case packing, and palletizing.
Step 3: Pushing and Transfer to Wrapping Section
Once the matrix is formed, a pneumatic or servo pusher transfers the arranged pouches toward the wrapping section.
This movement must be synchronized perfectly with film feeding and sealing operations. Advanced bundling machines maintain timing accuracy to avoid product damage or misalignment.
Automation at this stage ensures smooth product flow and high-speed operation without stoppages.
Step 4: Film Feeding and Wrapping
The machine then feeds shrink film or LD film around the arranged pouch bundle. The film is unwound from a roll and precisely pulled to wrap the matrix.
A servo-driven film pulling system ensures uniform tension and proper coverage. This prevents loose wrapping or film breakage.
In modern bundling systems, film changeover is quick and operator-friendly, reducing downtime between production batches.
Step 5: Sealing and Shrink Process
After wrapping, the bundle passes through a sealing system. The film edges are sealed using a web sealer to create a secure pack.
The sealed bundle then moves into a shrink tunnel where controlled heat shrinks the film tightly around the pouches.
This results in a compact, stable secondary pack that is ready for storage, transportation, or case packing.
Uniform shrink ensures better stackability and protection during logistics.
Step 6: Discharge and Ready for Dispatch
The final bundled pack exits the machine and moves toward downstream systems such as checkweighers, carton forming machines, or palletizers.
Because the bundles are consistent in size and shape, further automation becomes easier and more reliable.
Why Automation in Pouch Bundling Matters
Manual bundling leads to inconsistent packs, labor dependency, and slower production speeds. An automated pouch bundling machine ensures:
Higher output with stable speed
Accurate pouch count in every bundle
Reduced labor cost
Improved packaging consistency
Better transport safety
For growing FMCG and food manufacturers, this directly improves ROI and operational efficiency.
