Introduction
There are various types of packaging integrity testers for checking the integrity of the packaging. The selection of different types depends on the product and packaging being used. Each type has a separate application and cannot be interchanged from other types.
For optimum and reliable results, it is necessary for the concerned personnel and operators to know various types of packaging integrity testers. Otherwise, it will result in the wrong selection of integrity tester and affect the integrity of the packaging.
How do select different integrity testing methods
As discussed above, there are different types of packaging integrity testers. For accurate results, it is necessary to study the requirements and select the packaging integrity tester.
Below are some criteria that can help select the correct packaging integrity tester.
Inline vs. Offline
Inline integrity testers check the integrity of packaging during production without taking the sample away from the machine in the laboratory or test bench. The test is performed in the running condition of the machine without stopping or halting the production process. Inline testers are integrated with the production machine. The production machine's main controller continuously monitors these testers' output. A mechanical assembly separates the defective packaging from the correct packaging by taking command from the main controller of the machine.
Offline testers check the packaging integrity away from the machine. The machine is stopped from taking samples until results are obtained. The test is often performed in the laboratory or on a separate test bench. When the trial is concluded, the result is communicated to the concerned personnel for further processing.
Primary Packaging Type
The packaging material that comes in direct contact with the product is called primary packaging material. Integrity testing for each primary packaging is different and follows a different technique and methodology. For example, the integrity tester for a blister pack cannot be the same as that of ampoules.
Filled Container or empty Container
Integrity tester also depends on whether the Container being tested is empty or contains a product. Some test methods are not suitable for empty containers, as they damage the Container and cannot be used for the product. Similarly, some test methods are not suitable for filled containers, as it affects the test output.
Product Type
Packaging integrity testing also depends on the product being used in packaging material. Different test techniques behave differently on different products. Packaging integrity testing can output inconsistent results if the appropriate product type is not correctly selected.
In some cases, a particular test method is not suitable for liquid products, while others are not suitable for the solid dosage form. They produce unreliable and erratic results when the appropriate product type is not considered.
Destructive Vs. Non-destructive test
Packaging integrity testers can be divided into destructive and non-destructive. They are classified according to the usability of the packaging after performing integrity testing.
Destructive Testing
Destructive testing refers to the destruction of packaging, and the product inside it requires re-packing before marketing or reaching its intended user. The product remains safe and can be used for consumption by its end user.
In Destructive testing, the test mechanism penetrates the packaging material or is performed by immersing the packaging into the sole liquid. This method destroys the packaging, and the product is exposed. The product requires re-packing before it reaches its intended user.
Non - Destructive Testing
In non - destructive testing, the packaging is not dest...
