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:
o Setup Vac-Pack™ attachment as shown (figure 1).
o Apply septa to clean dry portion of package (figure 2)
o Insert needle through septa into package. Avoid clogging needle with product.
o Close 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.
