Film/Laminate Mechanical Properties Test
Optimise Durability of your package with Film/Laminate Mechanical Properties Testing!
A flexible package has to survive filling, sealing, transport, stacking and handling on the shelf. Whether it holds up depends on the mechanical strength of the film or laminate it is made from. Variations in thickness, poor scuff resistance, unexpected shrinkage under heat, or low impact and tear resistance can lead to pack failures, product damage and customer complaints.
Flexitest offers a range of film and laminate testing instruments for packaging labs. The range covers thickness measurement, rub and abrasion resistance, thermal shrinkage in the machine and transverse directions, falling dart impact (F50) and Elmendorf tear propagation. With these instruments, flexible packaging converters, food and beverage, pharmaceutical, personal care and agrochemical packaging manufacturers can compare materials, control quality and check performance against ASTM, ISO and customer specifications. Flexitest supports every installation with training, service and a quick response.

❓ Frequently Asked Questions – Film/Laminate Mechanical Properties Tester
What is Film/Laminate Mechanical Properties Testing and why is it important?
Film and laminate mechanical properties testing measures thickness and evaluates abrasion resistance, thermal shrinkage, impact resistance, and tear resistance. These tests help packaging manufacturers compare materials and check their physical performance for the intended packaging application.
What instruments does Flexitest offer for Film/Laminate Mechanical Properties Testing?
Flexitest offers a complete range of five dedicated instruments for this category: the Thickness Tester C640 for precise film thickness measurement, the Rub Tester RT-01 for print and surface abrasion resistance, the Thermal Shrinkage Tester C631H for heat-induced dimensional change, the Falling Dart Impact Tester C670M for impact strength evaluation, and the Elmendorf Tearing Tester C680M for tear propagation resistance – covering all key mechanical performance parameters of films and laminates.
What does the Thickness Tester C640 measure and which materials is it suitable for?
The Thickness Tester C640 accurately measures the thickness of films, laminates, foils, paper, nonwovens, and other thin flexible materials. Consistent thickness is a fundamental quality parameter – it directly affects barrier performance, mechanical strength, seal quality, and material cost efficiency. The C640 provides precise, repeatable thickness readings critical for incoming material inspection, production quality control, and compliance with packaging specifications.
What is the Rub Tester RT-01 used for in packaging testing?
The Rub Tester RT-01 evaluates the abrasion and scuff resistance of printed or coated surfaces on films, laminates, and flexible packaging materials. It simulates the friction and rubbing that packaging experiences during filling, transit, and retail handling. This test helps manufacturers verify that inks, coatings, and surface treatments do not fade, smear, or degrade – ensuring that brand graphics and product information remain intact throughout the packaging’s lifecycle.
How does the Thermal Shrinkage Tester C631H work and what does it test?
The Thermal Shrinkage Tester C631H measures the dimensional change – both in the machine direction (MD) and transverse direction (TD) – that occurs when a film or laminate is subjected to heat. The specimen is placed in a heated oil bath or oven at a controlled temperature, and the percentage of shrinkage is calculated after cooling. This is especially important for shrink films, retort packaging, boil-in-bag products, and any flexible packaging that encounters elevated temperatures during processing or sterilisation.
What is the Falling Dart Impact Tester C670M and what does it evaluate?
The Falling Dart Impact Tester C670M measures the impact resistance of plastic films and laminates by dropping a weighted dart from a defined height onto a clamped film specimen. The result indicates the energy at which 50% of specimens fail – known as the F50 value. This test is essential for assessing how well a packaging film resists puncture and impact during transit, drop events, and mechanical handling, making it a key quality indicator for films used in heavy-duty bags, pouches, and wraps.
What does the Elmendorf Tearing Tester C680M measure and why does it matter?
The Elmendorf Tearing Tester C680M measures the tear propagation resistance of plastic films, laminates, paper, and nonwovens – specifically the force required to continue propagating an already-initiated tear. A pendulum mechanism delivers a controlled tearing force, and the result indicates how easily a material tears once a nick or cut is introduced. This property is critical for films used in packaging that must resist accidental tearing during use while also being easy to open intentionally – balancing functional performance with consumer convenience.
What are the key considerations when selecting a Film/Laminate Mechanical Properties Tester?
When choosing a testing instrument for film and laminate mechanical properties, the key factors to evaluate are precision and accuracy of measurement, compliance with relevant test standards (ASTM, ISO, etc.), compatibility with the material types being tested (plastic films, aluminium foil, paper-plastic laminates, etc.), speed and testing efficiency, cost-effectiveness for the lab’s throughput requirements, and data traceability for quality records and regulatory compliance – all of which are prioritised in Flexitest’s instrument offering.
Which industries commonly use Film/Laminate Mechanical Properties Testing equipment?
These instruments are widely used across flexible packaging converters, food and beverage manufacturers, pharmaceutical packaging producers, personal care and cosmetics brands, agrochemical packaging units, and retail and e-commerce packaging suppliers. Any industry that relies on films, laminates, foils, or multi-layer structures as primary or secondary packaging requires regular mechanical property testing to validate material performance, meet buyer specifications, and comply with industry quality standards.
