The Vertical Flow Wrap Machine adopts dual servo motor drive and PLC intelligent control system to achieve a stable packaging speed of up to 120 packs/minute. Combined with PID independent temperature control technology, it ensures the airtight sealing of the composite film under high-speed operation, significantly improves the production yield and undertakes wholesale business.
30-120 packs/min
Packing speed
80-300mm
Bag length
420mm
Maximum film width
Double servo motors are used to control the film pulling mechanism, and the positioning accuracy reaches 0.2mm. Compared with the traditional stepping motor, the bag length error during high-speed operation is reduced by 80%, effectively preventing the pattern from deviating, and saving about 5% of the packaging material loss for the factory every year.
The vertical seal and the horizontal seal adopt independent PID temperature control module, and the temperature fluctuation is controlled within ± 1 ℃. This technology ensures that BOPP, PE or multilayer composite film can achieve 100% airtight sealing at different thicknesses to avoid air leakage and moisture.
The contact material part of the machine is completely made of 304 stainless steel, and the core components meet the IP65 protection level. The smooth hopper design without dead corners prevents powder or particle residues, reduces the cleaning time by 40%, and fully complies with GMP food hygiene production specifications.
Built-in 7-inch industrial touch screen supports the storage of more than 50 sets of product parameter formulas (such as different gram weights and bag lengths). When switching products of different specifications, the operator only needs to call with one key, and the adjustment time for production replacement is shortened from the traditional 30 minutes to less than 5 minutes.
Equipped with high sensitivity optical eye tracking system, can automatically identify the color code and adjust the correction. When the film coil is slightly deviated, the equipment will automatically correct within 3 packaging cycles, reducing the frequency of downtime adjustment and improving the overall efficiency of the equipment.
The control system reserves the standard signal interface, which can seamlessly connect the multi-head combination scale (particle), screw metering machine (powder) or piston pump (liquid). This modular design allows the same host to adapt to a variety of packaging materials from potato chips to milk powder by replacing the feeder.

Applicable to the production of potato chips, popcorn, shrimp, nuts and other granular puffed food enterprises. The high-speed flexible film drawing technology of the equipment can effectively prevent fragile food from breaking in the process of blanking and packaging, and at the same time support the function of filling nitrogen to ensure the crisp taste of food.
It is suitable for pharmaceutical factories producing cold granules, powder, tablets or capsules. The 304 stainless steel body and fully enclosed design meet the strict requirements of hygiene and cleanliness, can prevent cross-contamination, and the high-precision metering system ensures that the dose of each bag of medicine is accurate.
Suitable for the production of screws, nuts, gaskets, furniture accessories and other small hardware manufacturers. With the vibrating plate counting device, the equipment can use thickened composite film for strong packaging, can withstand the sharp edges and corners of metal parts, to prevent packaging damage during transportation.
It is suitable for chemical enterprises producing seeds, pesticide powder, washing powder, desiccant and other products. The sealed electrical cabinet of the equipment reaches the protection level above IP54, which can effectively isolate the erosion of corrosive dust on the circuit system and ensure the long-term stable operation of the equipment in the dust environment.
Install the packaging roll film on the rear release shaft, ensuring that the center of the roll is aligned with the center of the former. According to the schematic diagram of film penetration on the side of the machine, the film is passed through the tension rod, the position of the coding machine, the detection area of the photo eye, and finally introduced into the former. The correct wear film can prevent the film running deviation. [6]
Enter the HMI main interface after power on, and input the target bag length (e. g. 150mm) and production speed (e. g. 60 bags/min). If it is a product that has been produced, directly click “Formula Reading” to select the corresponding preset number (1-50), and the machine will automatically load the corresponding temperature, photo-eye sensitivity and other parameters.
Move the photo sensor to align with the eye mark on the edge of the film. Do the “jog” test in manual mode and observe the signal feedback on the screen. Adjust the sensitivity knob to ensure that the sensor can clearly distinguish the color difference between the color code area and the background area, so as to ensure the accurate position of the cutting bag.
Turn on the temperature control switch and preheat for 5-10 minutes to the set temperature (such as horizontal seal 140 ℃ and vertical seal 130 ℃). First, run the empty bag to check whether the sealing lines are clear and the air tightness is good. If the sealing is not firm, the temperature shall be gradually increased by 5 ℃; if there is hot wrinkle, the temperature shall be appropriately reduced or the sealing pressure shall be increased.
Efficient vertical forming, filling, and sealing.
Ideal for bulk granular or liquid items in small floor spaces.
Delivers premium packaging quality for doypacks.
