A packaging seal strength test is used to measures the strength of the seals in the packaging material to prevent the package from opening during handling and transportation. Seal strength is typically measured in terms of force required to open or peel apart the sealed layers. Seal strength tests include:
It’s important to note that test rigs can accommodate single product testing and complete seal package testing. After all, sealing a hydraulic cylinder is a team effort, requiring all individual parts to interact as expected in unison. Sealing packages need to be carefully selected with the application and customer’s expectation in mind.
