On May 8, 2021, Sywen Packaging received an inquiry from Hamburg, Germany about the automatic soy flour powder bag packaging machine. The content is as follows:

We need to package bulk soy flour in bags, there are two types and sizes of packaging bags. Which powder packaging machine meets our filling requirements?

Our reply on May 9, 2021:

What type of two kinds of bags are there? How many grams are in a bag? Please send us the picture of sample bags. What are the length and width of the two bags?

Email from the customer on May 11, 2021:

One is a stand-up pouch with a zipper, length 240mm x width 135mm, and the other is a back seal flat pouch, length 235mm x width 140mm, both are 500g per bag.

Soy Flour Powder Pouches

Our reply on May 12, 2021:

From the picture, the sealing type of the two bags is simple, both are straight line sealing. If you want to use the same automatic powder bag packaging machine for filling and sealing, only need to keep the sealing pattern of the two bags is the same.

According to the style and size of the bag, we recommend you SF-250 automatic powder bag filling and sealing machine, which can pack finished bags with a width of 120-240mm and a length of 140-340mm with the three-side seal, four-side seal, stand-up bag, bottom gusset bag, flat pouch and etc.

What are the required filling accuracy and speed? The machines of the same model have different configurations according to the specific packaging requirements.

Email from the customer on July 9, 2021:

The ideal accuracy error of 500g is about 2g, and the speed is about 15 bags/min.

Our reply on May 17, 2021:

This automatic pre-made bag powder filling and sealing machine can be made into the screw auger or weighing system measurement. The measurement accuracy of the screw auger can only reach 1%, that is to say, the accuracy error of 500g of soy flour is about 5g.

For weighing system measuring, the filling accuracy can reach 3‰, when filling 500g soy flour, the filling error per bag is about 1.5g. The required filling accuracy is 2 g/bag, so the machine needs to be made as a weighing and filing system for soy flour packaging.

In addition, in order to obtain higher filling accuracy, this model of automatic powder bag packaging machine needs to be made into two filling heads. For example, when filling 500g of soy flour, the first filling head will fill 480 grams firstly at a relatively fast speed, and then the second filling head will fill the left 20 grams with a relatively slower speed. 500g soy flour will be filled with a fast and slow speed twice to complete high-precision weighing and filling.

Email from the customer on May 18, 2021:

The thickness of the two plastic bags is different. Will it have any effect on the sealing?

Our reply on May 18, 2021:

The automatic powder bag filling and sealing machine has an intelligent temperature control instrument, and the sealing temperature can be adjusted according to the thickness of the pre-made pouch. For example, if the plastic bag material is relatively thick, the sealing temperature can be appropriately increased. If the bag material is relatively thin, the sealing temperature can be lowered appropriately.

Email from the customer on May 19, 2021:

The sizes of the two bags are different. What parameters need to be adjusted when changing the bag sizes?

Our reply on May 19, 2021:

You only need to set the length and width of the bag on the touch screen, and the machine clamp of each packaging station will automatically adjust the width synchronously, without any manual adjustment.

Email from the customer on May 25, 2021:

Assuming that the sealing patterns of the two bags are the same (straight lines or checkerboard), and the widths of the sealing openings of the two bags are different, can use one machine for packaging?

Our reply on May 26, 2021:

Yes, the width of the bag sealing can be adjusted within 3 cm.

Email from the customer on June 2, 2021:

Please make a detailed FOB China Port quotation, listing out what other packaging equipment is needed.

Our reply on June 3, 2021:

Regarding the production date, do you manually code after filling or print it on the bag when packaging? The quotation of the machine may include or not include a fully automatic coding machine.

Email from the customer on June 4, 2021:

It is necessary to print the production date directly on the outside of the bag when packaging. What kind of coding style is this machine? Thermal printing or something else?

Our reply on June 5, 2021:

This model of automatic powder packaging machine has two coding types, ribbon printing, and steel print coding. As shown in the figure, which one is more suitable for your company’s soy flour packaging bag?

Premade Pouch Coding Types

Email from the customer on June 7, 2021:

The steel print coding is more suitable, and our soy flour packaging bags have been using this coding style all the time.

Our reply on June 9, 2021:

Please see the attached detailed quotation. It contains two machines, a fully automatic pre-made bag powder filling machine with 8 packaging stations (8 machine clamps) and an automatic powder conveyor. The delivery time is about 35 days.

Email from the customer on June 16, 2021:

We have also received quotations from other manufacturers, some quoted for the horizontal automatic powder bag filling and sealing machine. What is the difference between your machine and the horizontal automatic powder bag packaging machine?

Our reply on June 17, 2021:

Both machines can fill powder pre-made pouches manually. However, there are differences in the adjustment difficulty and scope of the application when having several bag size in a certain range.

For filling 500g soy flour in the same bag, the price of the two machines is almost the same, there is no big difference, but the horizontal automatic bag powder packaging machine is more suitable for single-size bags, if you change the bag size within the range of machine support, you need to manually adjust the width of each bag clip. For example, an eight-station horizontal automatic powder bag packaging machine has a total of more than 50 screws, and it usually takes 2-3 hours to adjust all the machine clamps.

And our turntable type automatic powder pouch packaging machine is well suitable for packaging bags of various sizes (within the range of bag width and bag length supported by the machine model). To adjust the machine clamp, you only need to enter the bag size data, and the machine clamp will automatically adjust, it can be completed in a few seconds to change another bag size and start packaging.

In the next four months, we further communicated with our customers on the filling process, packaging videos, the list of core accessory brands and etc. The customer still doubt the packaging performance of our machines. We made a suggestion to him, the factory has the machine sample of this machine, he can send us some sample bags, we will help him do the packaging tests for free. After seeing the real packaging performance, you can make a final decision.

The customer agreed to our suggestion and sent the sample bag to us, we received the sample bag from the customer on October 20, 2021, we started to test by wheat flour on October 21, 2021, and sent the test report and video to the customer on October 24, 2021. After more than two weeks of consideration, we finally received a 30% deposit of the order on November 9, 2021.

If you are looking for a fully automatic powder pouch packaging machine, you don’t know much about the machine’s application range, filling accuracy, bag type, machine structure, etc., we hope the above soy flour packaging case can give you some help.
