Post-Process
Testing of Sealed Food Pouches
 The
customer produces a wide variety of food products,
many of which are packaged into flexible PVC or
PET pouches. The pouches are of various configurations,
sizes and closures such as peelable or resealable.
The need was for a quick, highly accurate seal
strength test system that would accommodate this
variety of primary packaging for use in audit
tests. TME provided the customer with a system
consisting of the TME BT-1000 Automated Package
Tester, the patented Package-Port™ leak tight
package entry system, and a restraining plate
fixture. This system optimizes seal strength results
by performing inflation pressure decay tests that
reveal any weak areas of the package seal as well
as the order in which the seals will open. Test
data are maintained in the Datalog of the BT-1000
instrument. Statistical data analysis capability
includes mean and standard deviation calculation
as well as control chart development, which permit
fast and accurate audit testing for lot disposition.

Seal
Strength Test of Partitioned Retortable Food Trays
 The
customer produces prepared meals that are packaged
into two-well thermoform trays sealed at the outside
edge and across the well partition with food-grade
film. TME was asked to provide a seal strength
test system that would provide information on
which cell's seals will rupture first under stress,
and also whether that rupture would occur at the
partition or at the outside seal. The test system
consisted of the TME BT-1000 Automated Package
Tester, a sensor and inflation probe, and the
Package-Port™ leak tight entry system. Valves
built into the test probe enabled separate and
concurrent inflation seal strength tests to be
performed on each of the two wells. This system
provided the customer with the necessary information
quickly, repeatably and with no operator influence.

Flow Test of Perishable Food
Container to Confirm Vent Rate
The customer manufactures cylindrical paper containers
for perishable food. In order to maintain the
quality of the food for its shelf life, specifications
for the vent rate of gas through the cylinder
had been determined by the manufacturer. The customer
already had a fixture designed to hold the cylinder
for testing, and TME was asked to provide a way
to confirm that the manufactured cylinders met
these vent rate specifications before filling
and sealing. The TME Solution™ four port
test instrument was configured to perform concurrent
flow tests on four cylinders at a time. The cylinders,
already sealed at one end, were sealed at the
fixture and a flow test was performed. If the
rate of flow of pressurizing gas through the permeable
paper was above or below the acceptable range
indicated by the customer's specifications, the
container was rejected.
