Mechanical Properties

Mechanical, material and technological properties

Film properties play a central role in the performance of modern flexible packaging and can be divided into mechanical, material and technological properties.

Mechanical film properties such as tensile strength, elongation, puncture and tear resistance determine the load capacity of a packaging film in the processing and application process.

Material properties result from the polymer structure and material combination, for example in PE, PP, PA or multilayer composites, and influence barrier behavior, resistance to chemicals and recyclability.

Technological film properties, on the other hand, include aspects such as sealability, slip and antiblock behavior, printability or suitability for specific processes such as thermoforming, laminating or coating. Only the coordinated interaction of these properties enables functional, safe and sustainable packaging solutions for food, pharmaceutical and non-food applications.

We offer these technological/mechanical test methods

To determine the mechanical and technological properties of your product, we use various test methods. You can then use the findings from these tests to improve the properties of your product or to create and validate specifications. This is often a requirement of quality standards or audits.

We offer you the following mechanical and technological test methods, among others:

Tensile test (incl. tensile strength, elongation at break, secant modulus)

Coefficient of friction COF

Bond strength

Sealing tests (determination of sealing properties)

Further specific tests

The practical characterization of the mechanical and technological properties of packaging materials using standardized accredited laboratory test methods requires a high degree of experience and modern equipment. In addition, the relation to production and packaging processes is often crucial for the interpretation of the results. This is exactly where Innoform positions itself as an expert team with over 25 years of experience.

The results serve to create and monitor technical specifications, to evaluate test series or sample productions and to process damage cases. With us, your test orders are in proven hands. Your questions become our testing tasks.

In practice, the interpretation of test results makes the difference.
