VG-602 / VG-402 Series

Electric/Microcomputer Controlled Vacuum & Gas Flushing Impulse Sealer

Vacuum, Gas flushing & Seal by optimum temperature

Figure 1

When you want to flush the air inside the bag and reduce the package volume, or when you want to utilize oxygen scavenger to extend product life, you can use the Vacuum Sealing function.

When you want to fill the bag with nitrogen gas to prevent oxidation, or with carbon dioxide to create bacteriostatic or insect-repellent effects or to prevent spoilage and mold growth, you can use the Gas-flush Sealing function.

The world is full of different things that beg to be packaged.

Basic function and performance for all VG-602/402 series

Standard equipped with heating-temperature control


Setting the ideal sealing condition

The most prominent feature of the Onpul System is the ability to set and maintain the ideal sealing condition.

The heating temperature setting is made possible through the use of a high-sensitivity temperature sensor for temperature control, and a microcomputer controller.

You can now complete the heating process at just the right temperature for melting the film regardless of the air temperature or fluctuations in the machine temperature.

  • Seal heating temperature: 60 to 250ºC/ 140 to 480˚F
  • Seal cooling temperature: between 40ºC/100˚F and the seal-heating temperature

The seal-cooling temperature must be set at a value lower than the user-defined heating temperature setting. If the cooling temperature is set at a value too close to the heating temperature, cooling will not take place and result in the shortening of the life of some parts, including the Teflon part.

Easy-to-operate microcomputer controller

The selection and setting of work method and vacuum method, as well as of gas-flush method and its frequency, are all controlled at the microcomputer controller.Simply press the touch panel buttons for the settings.

Switch among 13 different sealing methods

The following sealing methods can be combined to create a total of 4 different sealing methods. Select a sealing method to meet your needs, including selecting to best suit the characteristics of the packaged material and to obtain your desired packaging finish.

  • Work method options
    • Multiple gas flush cycles
    • Vacuum + Seal
    • Seal only
  • Vacuum method options
    • Vacuum gauge (0 to −100kPa)
    • Vacuum timer (0 to 99.9 seconds)
    • Manual operation
  • Gas-flush method options
    • Multiple flush cycles (up to 99 times)
    • Single gas flush
    • Circulating gas-flush : Set one of the two nozzles for vacuuming and the other for gas flushing. This will increase the gas-replacement rate by de-airing the bag even as the bag is being filled with gas. Especially effective with soft contents.
  • Gas flushing timer setting (setting range: 0 to 99.9 sec.)

Details of 13 different sealing methods:

  1. Seal only
  2. Vacuum by manual + Seal
  3. Vacuum by timer + Seal
  4. Vacuum by vacuum gauge + Seal
  5. (1 time) Vacuum by manual + Gas flushing + Seal
  6. (1 time) Vacuum by timer + Gas flushing + Seal
  7. (1 time) Vacuum by vacuum gauge + Gas flushing + Seal
  8. n-times Vacuum by manual + Gas flushing + Seal
  9. (n-times) Vacuum by timer + Gas flushing + Seal
  10. (n-times) Vacuum by gauge + Gas flushing + Seal
  11. Vacuum by manual + Circulating gas flush + Seal
  12. Vacuum by timer + Circulating gas flush + Seal
  13. Vacuum by vacuum gauge + Circulating gas flush + Seal

Max. 10 operation patterns can be stored

Maximum 10 operation patterns can be stored in the microcomputer controller.Operator can select the stored operation pattern for routine seal work under the same condition setting.

Adjustable table height and angle

The height and angle of the table (standard equipment) can be adjusted to suit the package content.

Maintenance mode

The state of the machine can be checked by displaying the Maintenance Mode on the LCD screen. Problems can be addressed and resolved at an early stage by checking the blinking areas in the Maintenance Mode and performing any necessary repairs.

Figure 4

Switch to circulating gas flush method

By modifying the piping, it is possible to switch to the circulating gas-flush method. With one nozzle set for gas flushing and the other for vacuuming, the circulating gas-flush method increases gas-replacement rate by de-airing the bag even as it is being filled with gas.

Circulating gas-flush

Vacuuming and gas flushing are conducted simultaneously.

Figure 5

Ordinary vacuum gas-flush

Vacuuming and gas flushing are two separete processes

Figure 6

Adjustable sealer head angle

The head of the sealer can be adjusted at between 0 and 30 degree angles to suit the package content.

Figure 7

For example, when packaging powders, tilting down the sealer head will allow the sealing to complete without powder spilling from the bag opening.

Adjustments can be made using the hand wheel located on the front panel of the machine.

Figure 8

Standard-equipped with air filter and automatic water-drain device

A nozzle-equipped vacuum sealer sometimes may inadvertently take in the bag's contents via the nozzle during the vacuum process.

To counter this problem, the VG-602/402 series comes standard-equipped with air filter to collect foreign objects (liquid, powder, etc.) that were inadvertently taken in during the vacuum process, and prevents the objects from entering into and damaging the vacuum pump.

In addition, by turning on the automatic water-drain device, the foreign objects collected in the air filter can be automatically discharged from the machine after each sealing process.

Drive-method two-nozzle mechanism

The horizontal distance between the two nozzles can be adjusted to fit the size of the bag.

Figure 9

Note: The horizontal distance adjustment between the nozzles will not be available if the optional printer FEP-V is installed.

Standard-equipped dry filter

The compressed air generated by the built-in compressor sometimes may contain drops of water from condensation, which can enter the machine through the piping and cause damage. To counter this problem, the VG-602/402 series comes standard-equipped with dry filter, which removes drops of water from the compressed air to prevent them from entering into the cylinder and piping inside the machine.

Selective high-performance and high-functionality features

These are the main features and functions that should be considered prior to purchasing the VG-602/402 series sealers.

Choose the vacuum pump and drive to fit your needs

You can choose the compressor, which serves as the drive, and the various exhaust-velocity vacuum pump, which serves as the vacuum generator, based on your specific needs, usage environment and package content.
