2 Introduction
How do you guarantee to your customers that your packaging system is dependable once it leaves
your facility? That’s a complex question. Issues such as packaging material compatibility, sealing
machine set-up, and seal reliability in high altitude trucking and airfreight (see section 5.2) are just
some of the production variables that need to be taken into account. The manufacturing considerations
are countless. Fortunately, the Pack-Vac™Leak Detector is a simple answer.
A systematic package testing system that incorporates the Pack-Vac Leak Detector will allow you to
quickly and reliably set-up packaging lines. The result: less downtime for machinery adjustments.
Additionally, continual process monitoring with the Pack-Vac Leak Detector will detect sealing problems
before they snowball, thus improving production yield. Above all, the Pack-Vac Leak Detector will catch
defects before they get to your customers.
3 Setup
The Pack-Vac is very easy to assemble and operate, just attach a compressed air line to the ball valve
on the right side of the base 86 P.S.I. (6 bar) minimum. For electric units, plug into appropriate power
source.
Caution !
The Pack-Vac is extremely heavy when filled with water. Be sure the table or cart is stable
and rated for the appropriate weight.
Caution !
Filling the Pack-Vac with water warmer than ambient temperatures may cause thermal
expansion of the plastic and the tank may crack. This is not covered under warranty. Please
call us for assistance.

4 General test method
The most common way to use the Pack-Vac™ is the bubble emission test.
oFill unit with enough water to submerge package when expanded. Water level will rise as pack-
age is expanded under vacuum.
oPlace product to be tested in the chamber and close the lid.
oCompressed Air Model- Open ball valve on right side of tank to generate vacuum.
oElectric Model- Push red slide valve on top of tank in towards fitting, switch on vacuum pump.
oAdjust vacuum level with brass bleed off screw on side of base. Clockwise to increase, counter
clockwise to decrease.
oIncrease vacuum until the package is expanded, see section 6. Bubbles will rise from a leak.
oCompressed Air Model- When testing is complete, close ball valve and vacuum will be re-
lieved.
oElectric Model- When testing is complete, switch off pump and slide red valve out to relieve
vacuum.
Note!
When testing a new package, always start with bleed screw at the lowest vacuum setting.
Slowly raise vacuum level to prevent sudden bursting, see section 6.
5 Alternative Testing Methods
5.1 Dry chamber testing
The unit can be used dry for simple burst strength and altitude testing. Also, a package containing liq-
uid with some headspace can be checked using the following method:
oPlace the product on a paper towel in the dry chamber.
oClose lid and start the vacuum.
oIncrease vacuum to fully expand package and put pressure on the seals.
oWhen finished, examine for leakage on the package or paper towel.

5.2 Empty bag test method
Empty bags should be sealed with some air in them to test properly. It is recommended that a block of
foam be placed in the bag to give a consistent volume for testing. This ensures that all operators will
achieve the same results.
5.3 Rigid tray, tub, or cup test method
Rigid packaging sealed with lid film can be tested with the lid film down if there is no product. It is
recommended that the test is performed with the lid film up if there is product. This allows the gas in the
headspace to escape if there are any leaks. Gases are much more easily seen than liquid product.
Some products can be tested with lid film down using the dry chamber method, looking for product (see
page 4).

5.4 Altitude simulation test method
Many shipping methods subject packaging to stress from changes in altitude. High altitude truck routes
can cause package expansion and failures. Air cargo holds are typically pressurized to only 9,000 feet
(2,743 meters). The Pack-Vac™ can reveal potential weaknesses in the package before shipping.
Altitude simulation can be done wet or dry. Vacuum levels can be converted to altitude with chart. Alti-
tude reading will be a differential from current altitude. For absolute altitude, add the local altitude of the
testing facility.

5.5 Vac-Pack™ attachment test method for vacuum packed products
The Vac-Pack™ attachment is used for vacuum packed product or product with very little headspace. A
true internal pressure can be calculated when using this device (see 5.6). Set up the test as follows:
oSetup Vac-Pack™ attachment as shown (figure 1).
oApply septa to clean dry portion of package (figure 2)
oInsert needle through septa into package. Avoid clogging needle with product.
oClose lid and start the vacuum at a very low level. It may be necessary to lower incoming air
pressure with the regulator on CA units. Package expansion is slower with the Vac-Pack™ at-
tachment in use.

6 Suggestions for setting 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.

7 Maintenance
The Pack-Vac™ requires little maintenance. The following guidelines will ensure years of service from
your Pack-Vac™
7.1 Cleaning
The Pack-Vac™ tank should be cleaned on a regular basis with mild soap and water to remove mineral
deposits before they degrade the clarity of the plastic. Using water with lower mineral content will delay
mineral build-up. Commercially available plastic polishers and cleaners by Novus can be used. Availa-
ble from www.mcmaster.com
7.2 Gasket installation
oRemove old gasket.
oThe lip of the gasket faces out!
oStart at the back center and press the ends together into the groove.
oNext, press each corner into the groove. Do not stretch the gasket.
