In fast-paced manufacturing environments where efficiency and precision are critical, multi-lane sachet packing machines have become the go-to solution for high-output packaging. These machines are widely used across industries such as food, pharmaceuticals, cosmetics, and chemicals—especially when companies need to package small quantities of liquids, pastes, or powders in sachets at scale.

In this article, we’ll take a deep dive into how a multi-lane sachet filling machine works, its core components, and why it’s the ultimate choice for high-speed pouch packing machine operations.

What Is a Multi-Lane Sachet Packing Machine?

A multi-lane sachet packing machine is a type of automatic packaging equipment designed to form, fill, and seal multiple sachets simultaneously in parallel lanes. These machines can typically handle between 2 to 10+ lanes, drastically improving production speed and efficiency.

Unlike single-lane systems, which process one sachet at a time, multi-lane machines are engineered for mass production of small-format packets like ketchup, shampoo, sugar, electrolyte powders, and more.

How a Multi-Lane Sachet Filling Machine Works

Here’s a step-by-step look at the process flow inside a multi-lane automatic sachet filling machine:

1. Film Unwinding and Alignment

The machine begins by unwinding a roll of laminated packaging film. The film passes through alignment rollers and tension control systems to ensure it feeds straight and smoothly across all lanes.

2. Film Slitting into Multiple Lanes

A slitting system divides the wide film into narrow vertical strips—one for each sachet lane. For example, an 8-lane machine will split the film into 8 strips, each aligned to one filling unit.

3. Vertical Sealing (Back Seal)

Each lane undergoes vertical heat sealing to form individual tubes from the slitted film strips. This is the first step in forming the sachet pouch.

4. Filling Mechanism

At this point, the product is dispensed into each formed tube. The filling system can vary depending on the product:

Auger fillers for powders (e.g., coffee, protein)
Piston or peristaltic pumps for liquids and creams (e.g., hand gel, ketchup)
Volumetric cup fillers for granular products (e.g., sugar, salt)

Each lane is synchronized to fill simultaneously, ensuring even distribution across sachets.

5. Horizontal Sealing and Cutting

After filling, the machine heat-seals the top and bottom of each sachet across all lanes. Simultaneously, the sachets are cut vertically and horizontally into individual packets, completing the packaging process.

6. Discharge and Collection

Finished sachets are discharged onto a conveyor or collection tray for further packing, cartoning, or boxing.

Key Components of a High-Speed Multi-Lane Sachet Packing Machine

PLC Control System – Ensures precise coordination between lanes
Touchscreen HMI – Easy recipe setup, diagnostics, and real-time monitoring
Servo Motors – For high-speed and accurate film pulling and sealing
Product-Specific Fillers – Customizable based on the material (liquid, powder, paste)
Photoelectric Eye – Detects printed marks for accurate cutting and sealing
Modular Lane Design – Allows adding or removing lanes for production flexibility

Advantages of Using Multi-Lane Sachet Packing Machines

High-Speed Output – Multiple sachets packed in parallel drastically increase throughput
Space Efficiency – Compact footprint compared to multiple single-lane machines
Labor Reduction – Fully automatic operation minimizes human intervention
Consistent Quality – Precise filling, sealing, and cutting across all lanes
Flexible Configurations – Easily adjustable for different sachet sizes and volumes

Ideal Applications for Multi-Lane Automatic Sachet Filling Machines

Food: ketchup, mayonnaise, sugar, coffee, salt
Pharma: oral rehydration salts, powders, vitamins
Cosmetics: shampoos, creams, lotions
Chemicals: detergents, disinfectants, lubricants

Conclusion

A multi-lane sachet packing machine is a powerful solution for businesses aiming to scale their automatic sachet filling machine operations. With its advanced technology, flexible lane configuration, and precise performance, it meets the demands of modern high-volume manufacturing.
