8. What Is The Working Principle Of Sachet Machine?

Working Principle Of Sachet Machine -sourced: foodmachinesale

• Once the sachet machine starts, you need to set related speed and efficiency parameters on the touch-screen control panel;
• After the parameters are set and confirmed, the films will start to unwind and then be folded;
• The prototype of the sachet will begin to unfold. The photocell will start to detect and fix the position where each sachet needs to be heat-sealed;
• When the determined film is determined and fixed, the machine will perform bottom seal and vertical seal;
• After being bottom and vertically sealed, the sachets will be printed with a tear notch;
• The next step is the cutting, sachet opening, and sachet filling. Before products are filled, they will be weighed or counted;
• When all materials have been filled into the sachets according to the parameters you set, they will be top sealed;
• After being counted, they will be discharged or transferred into the cartoning steps.

9. What Are The Main Parts Of Sachet Machine?

The main parts of sachet machine you need to know are:

Film Unwind

The film unwinds is designed to control the unwinding of the roll film. When you set different filling speeds, the film unwinds and unfolds at different speeds.

Film Guide

The film guide can help you control and fix the position and tightness of the film. Different film tightness will affect the bag-making effect of the following sachets.

Photocell

The photocell can be applied to detect where a sachet needs to be encapsulated. And provide a basis for a better encapsulation effect later.

Vertical Sealer

The vertical sealer is mainly applied for side-sealing the sachets. When the sachets are well-side-sealed, they will be cut along the edge.

Filling Nozzle

Generally, horizontal sachet machines have two filling nozzles, because this can improve the filling efficiency. When the powders are evenly mixed, they are filled into sachets in two batches.

Top Sealer

After sachets have been well side and bottom sealed, they will be top sealed and printed.

 10. Continuous Sachet Machine VS Intermittent Sachet Machine

Continuous and intermittent refers to different working methods of the machine.

Continuous Sachet Machine

Continuous Sachet Machine -sourced: medicalexpo

Continuous sachet machine means that they continue to work without stopping. The reels never stop. The sealing of the product is carried out without stopping the film. The speed and efficiency of the machine are very high.

Intermittent Sachet Machine

Intermittent Sachet Machine -sourced: IMA

An intermittent sachet machine means that they can be started and stopped at will while working. Even if the roll film is not used up. Machines can also be stopped and restarted. The sealing of the product is carried out when the film is not moving. If you have no requirement for the speed of product production, then a continuous sachet machine is a good choice.

	Continuous Sachet Machine	Intermittent Sachet Machine
Working Principle	Continuously working	Intermittently working
Application	Suitable for liquid product packaging;	Suitable for product packaging such as powder and solid;
Speed	High	Medium
Capacity	High	Medium
Machine Design	Prefer vertical design	Prefer horizontal design
Packaging Styles	Versatile	Simple
Operation	Relatively simple	More flexible

11. Which Filler Has To Be Chosen For The Sachet Machine?

Depending on the products, you can choose different fillers for your sachet machine.

For Powder Materials:

Auger Filler

Auger Filler -sourced: vtops

Auger filler can complete the continuous filling of various powder materials. Particle size in powders can affect flowability during filling. The smaller the particles, the higher the fluidity of the powder and the lower the internal pressure stability. The auger filler used can fill powders with different particle sizes and low fluidity according to different screw axes.

Volumetric Cup Filler

Volumetric Cup Filler -sourced: packaging-labelling

The Volumetric cup filler can be used to fill a wide variety of dry, free-flowing products. Different-sized cups can be used as replacements to accommodate a variety of different products.

It ensures that each sachet is filled with the exact dose of powder product. Some volumetric cup fillers are also equipped with a stirrer. This design keeps the products mixed and prevents them from settling.

Weighing Filler

Weighing Filler -sourced: sapli

Weighing filler mainly uses highly accurate load cells to determine the weight of the material. The product is sent to the hopper through the central vibrating top cone and vibrating feeder.

The hopper will drop the product into a weigh hopper, which will eventually flow into a central discharge chute. The flakes are then poured into a packaging machine.

For liquids and pastes:

Overflow Filler

Overflow Filler -sourced: millerbevco

The overflow filler is mainly used for high-fluidity liquid filling, such as water, juice, milk, alcohol, etc. By installing counting sensors, the filling nozzles can be directly connected to the filling nozzles of the sachet machine. The product in the tank is managed by sensors controlling the pump.

Piston Filler

Piston filler mainly uses a piston and cylinders to fill sachets with liquid, high-viscosity liquid, or pastes. Through the cylinder or the piston rod moving up and down by the motor, it can smoothly pour the material into the content bag.

 12. What Are The Troubleshooting For Sachet Machines?

If there are problems when you are running the machine normally, please don't worry and be afraid. Machines also need maintenance and protection. According to the following points, you can easily diagnose the problems encountered by the machine and deal with them accordingly.

Sachet Not Shaped

This may be caused by insufficient tension in the film. If the tension of the film is not enough, the sachet will not form or there will be holes.

Sachet Not Feeding

If the product is not accurate or is not being properly fed into the sachets, then you should check to see if the filler hose is damaged or clogged. Or if the sensor is blocked, dirty, or damaged.

Sachets Fail To Open

If the sachets fail to open it probably means the vacuum cup is malfunctioning. Or the sachets are placed too low.

Sachet Seal Weak Or Incomplete

You should check for worn or damaged seals. Is the heater working properly? Whether the temperature setting is correct. Whether the sealing jaws and sealing strips are working normally.

13. What Should You Consider Before Purchasing A Sachet Machine?
