tensile test films and laminates (temperature range -40 to +120 °C)

Determination of: secant modulus, tensile strength, elongation at break (accredited test method)

In short — AI-generated

In this tensile test, a strip of film or laminate is clamped into a testing machine and pulled at a constant speed until it breaks. The test is performed within a temperature-controlled chamber ranging from -40 °C to +120 °C to simulate various environmental conditions.

The results provide key mechanical data such as tensile strength, elongation at break, and the secant modulus, which describes the material's stiffness. Packaging developers use these values to ensure that films can withstand mechanical stress during production, transport, and use without tearing or deforming.
