General Methods Newest Unit
The S.I.V. III
(Seal Integrity Verification III)

The new SIV III features many ease of operation programming.

   The SIV III  new product is CE Certified for sales in the European Market.  
The SIV III program controls all the valve adjustments needed to create the proper vacuum during the test cycle.

   The new control test parameters can be downloaded to an SD card and uploaded to other SIV III units.

   PLC will store 1000 test results in the memory. 
   The new unit contains a 570 Color Unitronics PLC for easier operation  

   Test results can be read in US imperial measurements or Metric.

e food packaging industry depends on the integrity of the seal of the overwrap to preserve the quality of the products it produces.  The need for a reliable efficient way to test seal integrity is the direct result of the variables in package making equipment control settings and in film selection.

Designed specifically for the food packaging industry, the S.I.V. III meets the need to evaluate seam integrity in a production line environment through both leak and burst testing capability.  The seal test, decay test, and forced/decay are nondestructive.  The burst test or seal strength test are potentially destructive if taken to the burst point. 

The unique design of the S.I.V. III incorporates a color touch screen PLC to provide both automatic test cycle sequencing and data analysis. The programmable color touch screen is the key component in achieving the S.I.V. III design objective.  This test machine is extremely simple to operate, yet incorporates the sophisticated state of the art data collection devices required to insure accurate and repeatable test results. 

S.I.V. III's extremely durable construction utilizes stainless steel and lexan to meet the demands of the food packaging production line environment and is designed to be portable for convenient in-plant movement.


Acceptable seal leakage parameters established by the user for each of the various food groupings being packaged are programmed into the machine.  The operator simply selects the food code or scans the bar code for the packaged products being tested and closes the chamber door to initiate the test cycle.  Lights signal pass or fail at the conclusion of each test.  The machine will accurately test the seal of a product in a bag only, or with the bag inside of a box.

Seal strength parameters are also pre-programmed into the test cycle.  Operator selection of the burst test mode automatically tests the package to insure that it withstands a minimum force without bursting.

Optionally the operator can select a test cycle that will burst the seal allowing comparisons such as:

  Film thickness impact on burst strength
  Film suppliers optional products
Package equipment optimum jaw setting an    adjustments

Test parameters can be quickly and easily changed by an authorized individual using a login password to access the product setup parameters,  and inputting the new parameters directly through the PLC touchscreen.

 1000 test results are stored in the PLC memory and can be downloaded into a central Quality Control data system through an ethernet module OR downloaded to an SD Card for statistical evaluation or retrieved for viewing on the color touchscreen of the PLC.
