Vacuum or gas packaging

Vacuum or gas packaging

There are two types of vacuum and/or gas flushing machines:

  • Chamber machines: This method allows for high vacuum levels of around ± 99.98%, but the size of the bag is limited by the size of the chamber.

  • Nozzle machines: There is no volume limit for the products to be packaged. During the cycle, visual control of the product is maintained. The vacuum level is around ± 70%, so it is lower than with chamber machines.

When combined with a vacuum machine, shrink tanks offer the possibility of creating packaging with an aesthetic and professional presentation for your product.

Difference between a nozzle and a chamber vacuum packaging machine.
