How to Choose the Right Bag Former?

The key to selecting the correct former is to determine your required film width.
Calculation Formula:
Film Width = (Finished Bag Width x 2) + (Side Seal Width x 2)
Example:
  • Your desired bag width is 100mm.
  • The standard side seal width is typically 10mm.
  • Required Film Width = (100mm x 2) + (10mm x 2) = 220mm.
  • Based on the table above, you should choose the SF-M240 (200mm-240mm) bag former.

Need Custom Stainless Steel Forming Shoulder Parts?

If your film width is outside the above ranges, or if you need a custom stainless steel forming shoulder for special bag types (e.g., gusseted bags, quad-seal bags),
Please feel free to contact us.
We support fully custom orders for all types of stainless steel forming shoulder parts, starting from just 1 piece!
Are this specialized bag former and the conventional collar-type former interchangeable?

Generally, no. Their mounting bases and integration methods differ. This sachet packaging machine former is typically used for specific powder or liquid machine models, while the collar-type is more universal. Please confirm your machine type before purchasing.

 

What is the lifespan of the flexible structure?

We use high-quality flexible stainless steel that has passed tens of thousands of fatigue tests. Under normal use, the lifespan of the flexible structure is the same as the main body of the former, lasting at least 2-3 years.

Do you support custom, non-standard orders? What is the MOQ?

Yes, custom non-standard orders are one of our core strengths. We can meet your needs for special diameters, angles, or materials. The MOQ for standard products is 1 piece, and we welcome you to request a sample for testing.

How do I determine the correct model I need?
Simply provide your packaging machine’s brand and model, the outlet diameter, and your desired bag width and type. Our technical engineers will handle all the matching and design work for you.
