What Are The Important Factors You Should Know Before Buying A Spout Pouch Filling Machine?

1. What is a spout pouch?

The spout pouch, also known as a penguin bag, is a stand-up pouch with a suction nozzle and horizontal support structure at the bottom to help it stand on its own. Self-standing bags are a popular kind of packaging on the market today.

2. What factors will influence the design of the spout pouch filling and capping machine?

There are several types of stand-up pouches available on the market. Because the spout pouch filling machine is based on the pouch’s spout, the spout’s structure (the suction nozzle) is essential for the design.

  1. The spout’s slot can have one or two layers. Whether you have a single-layer or double-layer slot, how you load a pouch will also be different. It should match up with two different suction nozzles on the machine.
  2. There will be different shapes on the cap. When the size and shape of the cap are different, the way it screws on should be designed to match. The screw head for the standard cap and the screw head for the large head cap are different.
  3. The size of the bag determines how much the spout pouch filling machine can put into it. In general, this machine can hold 20% much more than the size of the pouch at its highest setting. This machine’s filling capacity is adjustable to fit the job, but the range of change shouldn’t be too big. Do not use the same filling system for 50ml and 500ml because the 500ml filling system isn’t precise enough for 50ml.

3. What products can be filled and capped using the spout pouch filling and capping machine?

This fully automatic spout pouch filling machine is suitable for filling and capping stand-up spout pouches. This machine can fill liquids, semi-liquids, or paste, such as soy milk, tomato paste, liquid laundry detergent, water, suction jelly, and so on. The condition of the liquid materials should be used to figure out the best way to fill the pouches.

4. What are the different types of spout pouch filling and capping machines? 

This spout pouch filling machine is excellent for industrial production. Based on how automated it is, it falls into two categories:

  • Fully Automatic Spout Pouch Filling and Capping Machine

This machine features automatic bag hanging, bag-free detection, automatic filling, automatic capping, automatic capping, uncapped detection, automatic capping, and automatic finished product output. This filling and capping machine has a high level of automation, such as multiple fault alarm systems, photoelectric detection, and PLC control, making it easy to keep an eye on how the equipment works in real-time. Second, the automatic cover-turning function uses a device with a constant magnetic torque that keeps the torque the same so that the caps of the same batch of products have the same tightness.

  • Semi-Automatic Spout Pouch Filling and Capping Machine

This machine has a low level of automation, the kind of equipment used in early small factories to try out new ideas. It can automatically fill, cap, and produce finished products. Unlike the fully automatic machine, this one doesn’t have automatic bag feeding support or automatic bag hanging. This means you have to hang the bag on the equipment’s turntable by hand. The machine’s capacity is based on how fast bags are hung by hand.

5. How to choose a spout pouch filling and capping machine? 

  1. Decide first the kind of packaging. Each spout pouch filling machine may work on the same suction nozzle bag. Maintain the stand-up pouch’s suction nozzle structure. Even if different bags are slightly different in size or shape, they can all be used in the same machine.
  2. Second, figure out the actual required manufacturing capacity. The following table shows the production capacity of the fully automatic spout pouch filling and capping machine when filling liquids.

Filling capacity per hour (in pouches) per filling nozzle

Number of Filling Nozzle Capacity (pouch per hour)
1 800-1000
2 1600-2000
3 2400-3000
4 3200-4000
5 4000-5000
6 4800-6000


What you should watch out for is that the machine’s capacity will go down if the filling materials don’t flow well or make a lot of foam. At this point, it might be a good idea to ask the technical staff for some professional advice.

6. How to print the date on the stand-up pouches?

At the beginning of the production process, many companies print the date on the bag by hand before buying an inkjet printer. This wastes labor. With labor costs increasing, finding ways to save labor is more important than ever. Most of the time, this problem can be solved in two ways:

  1. Install the printer on the machine itself. Before the pouch is filled, the date can be printed by putting the coding machine in the filling station.
  2. Set up the inkjet printer on the capping and filling machine. Before filling, the inkjet printer is also installed in the station. Because of the small size of the inkjet printer’s nozzle, it is suited for installation on filling and capping equipment. The date may be printed as long as the bag goes past the printing head.

 7. What is the price of a spout pouch filling and capping machine?

Spout pouch filling machines are made to fit the needs of the customers, so the price varies depending on the design and specifications of the machines.
