FPM is conveyor feet per minute. The formula to approximate BMP (bottles/minute) to FPM is:

FPM= BPM x spacing in inches ÷ 12


Spacing is the distance from the center of one cap to the center of the next cap
 


Speed estimates are based upon most severe scenario, fully loaded coil with cap touching cap through the full length of the sealing coil. It is not common to have the aforementioned in a practical packaging environment but this assumption must be made to provide general sizing guidelines. In most cases the bottle will be larger than the cap and will allow space between caps. Space between caps may allow for higher conveyor speed on some caps.

Note: These are only approximations. There are many factors to consider when testing maximum speed capabilities of a particular size induction sealer. To confirm size we recommended testing a suitable sealing coil, power supply and conveyor speed with your caps, bottles and foil liners in our lab.
