Suggestions for s
etting test parameters
Testing parameters must be set for each size and type of package. Frequency of testing, vacuum level,
water level (if any), and length of test are all variables that must be researched. Parameters can
change due to variances in package headspace. In some cases, operators should have an
understanding of the "look" of the expanded package more than trying to maintain a certain vacuum
level. With some research and training, the Pack-Vac will become an integral part of your quality
control program. General test parameters can be set up as follows:
Slowly apply vacuum pressure to package in a dry chamber (to prevent excessive clean up).
Raise vacuum level until the package fails, note vacuum level.
Repeat until a consistant failure point is found
Vacuum level should be set at approximately 70% of the failure point for future testing on the
production line as long as this level meets
Note !
The consistency of any test is dependent on the consistency of the package being tested.
Note !
It may be found that the package cannot meet minimum requirements for integrity. The Pack-
Vac™ is useful for testing new materials, machinery, and products before they are released to
production.
