What are packing principles of the horizontal form fill seal Linked twin sachet packing machine ?

0. Horizontal ffs twin sachet packing machine's film roll rack 
The film feeding station actually has a similar function to the previous film rack station. Both are responsible for releasing the rolled packaging film and providing packaging materials for subsequent stations. They may also perform some pretreatment tasks, such as printing codes and joining films.

1. printing information
The coding station is responsible for printing information such as the production date, batch number, expiration date, and bar code on the packaging bag. This information is crucial for product traceability, quality management, and market sales.

2. Bag forming
The forming station is the critical workstation responsible for shaping the packaging bags. As the packaging film passes through the former, it is molded into predetermined bag configurations, such as stand-up pouches, three-side seal bags, or four-side seal bags.

3. Bottom seal
The bottom sealing station is responsible for heat-sealing the bottom of the formed packaging bags, creating the bottom seal of the bags to provide a closed space for subsequent filling of materials.

4. Vertical seal
The vertical sealing station is responsible for heat-sealing the longitudinal edges of the packaging film, forming the side seals of the bags, further refining the shape of the packaging bags, and ensuring their tightness.

5. Easily tear notch station 
Perforated notches are made at specific locations on the packaging bags. The main purpose of the tear notch station is to allow consumers to easily open the packaging bags without the need for scissors or cutting tools, enhancing user experience and product convenience.

6. Cutter
It is used in the production of continuous-bag packaging. The main function of the virtual cutting knife station is to create tearable dotted lines or tiny incisions on the packaging film, so that end-users can easily tear the continuous-bag packaging along the lines of the virtual cutting knife and separate it into independent packaging bags. However, at the same time, during the packaging production process, the continuous bags still maintain a certain degree of connectivity, which is convenient for subsequent process handling.

7. Photo cell
The photoelectric detection station uses photoelectric sensors to detect color marks or labels on the packaging film, enabling precise positioning and cutting of the packaging bags. This ensures that the pattern on each packaging bag is complete and accurately positioned.
The servo bag pulling station is the core station for controlling the conveying of the packaging film and the accuracy of the bag length. 

8. Servo advance
The servo motor drives the traction mechanism to precisely pull the packaging film forward according to the set bag length parameters.

9. Cutting
The cutting station: cutting the continuously delivered packaging film into individual bags. The cutting position is typically controlled with precision by photoelectric detection signals or a servo control system, ensuring cutting accuracy and consistency in bag width.
 
10. Pouch opening
In the roll film packaging equipment, for packaging films that have added zipper, this station's function is to utilize a blade device to separate the pre-closed zippers as the packaging film continues to move. This action opens the zippers before the bags are formed, preparing for the subsequent filling station.

11. Air flushing
The bag opening detection station is used to detect whether the packaging bag has been successfully opened. If it is detected that the bag has not been opened or has not been fully opened, the system will send out a signal to stop the filling process or trigger an alarm to prevent material leakage and equipment failures.

12. Filling
The filling station: filling a predetermined amount of products into the opened bags accurately. According to the shape and characteristics of the packaged products, the filling methods include liquid pumps, screw pump, volumetric cup, electronic scale, etc.

13. Pouch stretch 
Before top sealing, the bag opening of the packaging bag is flattened to remove the wrinkles at the bag opening, in preparations for the subsequent high-quality sealing, and preventing situations such as unsealed areas or weak seals during the sealing process.

14. Heat top seal
"First top sealing adopts heat-sealing way to melt the PE/ PET to intergrate two layer into one for finishing final sealing. 
ensuring the sealing performance and freshness preservation of the product."

15. Cooling
Similar to the previous cold sealing station, the cold sealing station after top sealing cools and shapes the sealed part again, further enhancing the strength and appearance of the seal.

16. Outlet
The discharging station: convey the finished product, connecting to intelligent packaging system
