  1. Do visual inspection around machine making sure there no loose parts and or objects which could hinder moving parts; if unsure call your sales representative or technician at Packit.
  2. Set the depth of the green belt depending on the size of the bags being sealed.
  3. Once you have your machine plugged to power, you can start putting control switches on in the following order;
  • Put POWER switch on,
  • Turn up the SPEED dial to a reasonable speed of green conveyor belt
  • Turn on HEAT and COOL switches same time
  • Set temperature on control dial to 150ºC
  • Put PRINT switch on
  • Set print temperature to 100ºC
  • Turn POSITION dial halfway its travel [this determines where printing is done on the product package]

Printing can be disabled by switching off the PRINT switch!

The machine is ready for operation when red lights on both PRINT and HEAT temperature controllers come on.


  1. With your machine set as above, you will be able to seal any poly-clear bags of 65-85microns thick.
  2. Simply align the open end of bag to the guide [L-plate on far right hand side of machine], through the first set of pulleys from guide and leave it passing through heat seal bars and pressing set of pulleys on left side of machine.
  3. Do not test seal strength at this time until sealed part of bag is fully cooled down.
  4. You will have to make the machine faster or slower if burning or poor seal is noticed.

NB: Different bags material respond differently to heat so any adjustments to heat or speed should be done in small amounts!
