How to fill and seal spout pouch? Spout pouches are versatile packaging for many food and beverage products, including stews, condiments, blends, sugar syrup, beverages, energy drinks, probiotics, juices, and many more. They also work well with masks, conditioners, shampoos, facial oils, and soapy liquids.

Despite the packaging’s adaptability—it comes in various sizes, shapes, and styles—it may be challenging to implement an in-house system for a manufacturing line. For that reason, we’ll go over the benefits of using a pouch for your packing requirements and the steps for filling and sealing a spout pouch.

What is spout pouch?

A spout pouch is a bag type with a tube or spout attached to its top; it is both lightweight and sturdy. Because it is practical, affordable, and popular, this packaging is quickly replacing traditional methods in markets. It is suitable for a wide variety of liquid and semi-liquid products.

Pouch Making

Getting your pouches made or ordered is the first stage in pouch packing. Different kinds of pouches, ranging from 2 inches to 250 millimeters, are available; your choice will depend on the contents and the machine you’re working.

Printing of any type typically occurs in advance. To avoid any potential food contamination, this procedure uses specially designed ink that cannot pass through plastic. It will then send the pre-made pouches to you if you decide to buy them.

After receiving your pouches, you will feed them into the spout pouch filling machine’s magazine. This is some of the daily tasks that involves human help. More magazine capacity means less work time to run the machine. Spout pouch filling machines may feature pouch, spout, and cap magazines. They include hoppers for feeding content products into nozzles.

 The spout pouch filling machine aims to finish filling spout pouches. Here is a brief concept of the filling process:

  1. Pouch feeding. The width of the pouch is adjustable and fed into the machine clip through a top-down process.
  2. Production date printing features ribbon detection, shutting alerts when running out of the ribbon, thermal printer, and interactive screen display.
  3. Pouch opening. Step 1: Pouch opening. Step 2: Pouch detecting. Step 3: Blank out the pouch without material.
  4. Product filling. The machine will not fill and heat seal if it does not detect the pouch. Also, a smooth seal will not be possible if you overfill.
  5. Heat sealing at high temperatures and cold sealing at low temperatures are used for sealing.
  6. Reshape the seal so it looks its best as the final result.

The packing method might vary for different materials depending on their specific properties. You may have the stand-up pouch with spout with the pour spout and cap still attached. After filling the contents into the pouch through the hole on the top, heat seal it to keep it in place.

What to consider before filling spout pouches?

  1. The sealing temperature for different packing materials varies; after debugging, choose the correct temperature. Leaks are common with the low temperature and loose sealing. Excessive shrinking of the seal from overheating may compromise the packaging.
  2. At any stage during packing, the quality inspector should check the final pouches for tight sealing. If there are creases and poor sealing, modify the machine to prevent poor-quality products.
  3. After shutting down the spout pouch filler, remove oil and stains and maintain the inside air-dry and gas-free. To ensure a tight seal the next time you use the heat seal, remove any excess material.

How do you fill multiple-sized spout pouches on one machine?

This packaging machine serves several purposes and is adaptable to various liquid ingredients and pouch sizes. You can fit pouches of varying sizes by modifying the width and length of the pouch storage.

Spout Feeding

A rubberized pneumatic piston delicately pushes the pouches to one side inside the magazine to provide consistent feeding. Transferring pouches to rubberized conveyor clamps is done one by one using suction arms. While passing pouches to insert spouts, clamps tilt them.

Each spout feeds into its own pouch as it travels down a stainless steel tube from its magazine to the dispenser. 

Spout to Pouch

After sealing the spout, conveyor clamps deliver pouches to the air extractor. Your pouches are vacuumed to eliminate any air. 

Next, a fresh set of conveyor clamps closes immediately beneath the spout to prevent additional air from entering. Another conveyor carries these clamps to filling nozzles.

Your packaging continues with another significant step. There can be four injectors on this unit. Initially, they would fill four pouches all at once. For goods like epoxy that need more than one component, the machine may be programmed to inject the ingredients one by one.

Conclusion

A pouch filling machine is clearly a game-changer for any business. Our packaging machines can increase your company’s profitability in the long run by reducing shipping needs, floor space demands, and the need for human labor.
