IV. Full Packaging Process: From Automatic Bag Pulling to Palletizing and Warehousing
The operation process of a complete Marchi three-side sealing packaging machine production line is as follows:
- Automatic Feeding: The vacuum feeder conveys raw materials such as oatmeal, cocoa powder or oat flakes into the high-level storage hopper of the equipment.
- Bag Making and Pulling: The packaging film is formed into a three-side sealed bag type by the bag former, and the bag pulling system pulls it downward according to the set step distance.
- Precision Metering and Filling: Adopting cup metering system (1–100g adjustable) for volumetric filling according to material density. A leak-proof device is optional for mixed 3-in-1 oatmeal.
- Heat Sealing: Longitudinal sealing and transverse sealing molds work simultaneously to complete back sealing and bottom sealing to form a complete three-side sealed bag with clear sealing lines and good pressure resistance.
- Cutting and Coding: The flat cutter cuts according to the set bag length. Meanwhile, a date coder or inkjet printer is optional to print production date, batch number and other information on the bag surface.
- Finished Product Output: Finished bags are sent out via the finished product conveyor and enter the rear-end detection process.
- Weight and Metal Detection: The weight detector automatically reweighs and rejects unqualified products; the metal detector screens metal foreign matters that may be mixed in.
- Bag Arranging and Palletizing: Qualified bags are neatly arranged by the bag arranging machine and sent to the mechanical palletizing station through the automatic steering conveyor. The palletizing system stacks layer by layer according to preset layers and pallet patterns, and finally transported to the warehouse by forklift or AGV trolley.
The stable packaging speed of the whole line is 40–60 bags per minute, and the actual production capacity can be adjusted according to material characteristics and bag length, meeting the output demands from small and medium-sized factories to large-scale workshops.

VI. Common Customer Pain Points and Marchi Solutions
Pain Point 1: Powder leakage or material clamping at sealing. Many powder materials and fine particles tend to remain in the sealing area during sealing, resulting in poor sealing firmness.
Marchi Solution: Adopt mesh sealing mold to increase friction and sealing area; for ultra-fine cocoa powder, an anti-clamping air blowing device can be installed, and a vibration station is added in front of the cutter to reduce material residue at the sealing position.
Pain Point 2: Time-consuming cleaning during multi-product changeover. Switching from oatmeal to cocoa powder or 3-in-1 oatmeal will cause residual mixing inside the equipment and affect flavor and compliance without thorough cleaning.
Marchi Solution: The equipment adopts a quick-disassembly structure; the hopper, metering cup and former can be disassembled without tools. The stainless steel surface has no dead corners, supporting wet cloth wiping and compressed air purging. The overall cleaning time for production changeover can be controlled within 20 minutes.
Pain Point 3: Metering deviation leading to non-compliant net content. The cup metering may have an error of more than ±2% when material density fluctuates.
Marchi Solution: It can be upgraded to a weighing feedback metering system, matched with a weight detector to reject over-tolerance products in real time, controlling the dynamic error within ±0.5% and helping enterprises pass net content supervision spot checks.
Pain Point 4: Low efficiency of manual palletizing at the rear end and labor recruitment difficulty. Fast packaging speed cannot be matched by manual stacking, resulting in production line blockage.
Marchi Solution: Provide whole line integration from packaging machine to mechanical palletizing. One set of palletizing system can correspond to multiple packaging lines, automatically stacking according to pallet patterns, reducing handling frequency and labor costs.
Conclusion
For enterprises seeking a stable, easy-to-clean and flexibly switchable packaging production line for oatmeal, cocoa powder, oat flakes or 3-in-1 oatmeal, Marchi fully automatic three-side sealing packaging machine features food-grade stainless steel body, flexibly adjustable sealing and metering configuration, as well as whole line integration capability extending to palletizing, providing a cost-effective equipment solution.
