It is important to test any new packaging before it goes into production. This will ensure that it meets all your needs. The outer packaging must withstand extreme physical and mechanical stress.
They should also make sure perishable items are kept fresh until they are opened. Flexible packaging tests are essential to monitor the performance of a package under various stress conditions.
Flexible packaging and films have various test methods and requirements than rigid packaging. Flexible packaging requires additional testing, including resistance to flex cracking and seal strength.

These are just a few of the flexible packaging testing methods:
Flexible packaging material testing confirms the chemical and physical properties of flexible packaging materials.
Flexible packaging films such as shrink film and ordinary cling film are subject to tests that include tensile strength, surface energy, elastic modulus and moisture vapor transmission rate.
They also undergo heat seal resistance, heat sealing conditions, heat seal conditions, heat seal conditions, heat seal conditions, and others. The chemical property test is generally used to determine if the product will react with other foods or products.
Dimension test
The Flexible Packaging Test for Dimensions measures the dimensions of a package before it is filled. Flexible packaging can change shape depending on what is inside.
It is important to inspect the packaging when it is empty as well as when it is full. The standard tests include checking the length, width, depth, and thickness.
Dimensional testing includes testing the grammage and thickness of the packaging material. The grammage is usually measured in grams per square meter (GSM).
