How Does the Film Shrink Tester Work?

The film shrink tester works by exposing the film specimens to a controlled fluid medium that is heated to a specific temperature. During the test, the specimen’s linear shrinkage is measured as the material shrinks in response to the heat. The test results are essential for determining whether a film is suitable for its intended application, especially in packaging where consistent shrinkage is required to ensure a perfect fit.
