ASTM D1709
Standard Test Method for Impact Resistance of Plastic Film by the Free-Falling Dart Method
At Micom Laboratories, we offer ASTM D1709 testing services, which are essential for evaluating the puncture resistance of plastic films. This test evaluates material performance in sectors such as packaging, agriculture, and construction. ASTM D1709 determines the energy required from a well-defined rounded head dart to cause a film failure. By providing precise data, we help our clients select the best plastic films for their applications while meeting industry safety and performance standards.
About ASTM D1709 Testing
The ASTM D1709 test evaluates the puncture resistance of plastic films through controlled impact. While commonly used by packaging manufacturers to verify product strength, its applications extend to the medical industry, where it ensures that the packaging of sterile products can withstand accidental drops, protecting their contents from contamination. This test determines the energy required to puncture a film sample and applies to various materials, including polyethylene (PE) films, polypropylene (PP) films, PVC films, and laminated or composite films.
ASTM D1709 Testing Process
ASTM D1709 includes two test methods: A and B. The following data apply to method A.
1. Specimen Preparation
The process begins with preparing square specimens, each with sides measuring at least 6.5 inches (165.1 mm). Each sample is meticulously inspected for imperfections—such as defects and wrinkles—that could significantly affect the test results. Additionally, the thickness of each specimen is measured to ensure uniformity.
2. Conditioning
Before testing, specimens are conditioned under the same environmental conditions as the test, following the specifications outlined in the ASTM standard, for a minimum of 40 hours. This step minimizes the impact of external factors, such as temperature and humidity, on the results.
3. Drop Test
The test involves dropping the prepared and conditioned specimens from a predetermined height to evaluate their response under controlled conditions, ensuring the accuracy of the assessment results.
The drop test is performed according to the parameters specified in ASTM D1709. Method A uses a 38.10 ± 0.13 mm (1.500 ± 0.005 in.) diameter hemispherical head dart and specifies a drop height of 0.66 ± 0.01 m (26.0 ± 0.4 in.). To ensure robust data, we typically test a minimum of 20 specimens, though this number may vary based on factors such as material variability, project specifications, or client requirements.
In addition to the ASTM D1709 test, we also conduct various testing services for plastic films, such as ASTM D882, which evaluates tensile properties.
Benefits of ASTM D1709 Testing
- Quality control and assurance: Ensures plastic films reliably meet resistance standards, minimizing the risk of failures in practical applications.
- Product development and improvement: Provides critical data to inform enhancements in film formulation and design, leading to stronger, more durable materials.
- Compliance with industry standards: Validates that films adhere to safety and performance regulations, ensuring they effectively serve their intended purposes while facilitating smooth market entry and boosting customer trust.
- Performance validation: Confirms that plastic films can withstand real-world impacts, guaranteeing their reliability across various sectors, including critical areas like packaging and healthcare.

Enhancing Medical Packaging Safety: A Success Story
One of our clients in the medical packaging industry was facing issues with the durability of their sterile product packaging. They experienced frequent punctures and tears during transportation, putting the sterility and safety of their products at risk. By partnering with Micom Laboratories and utilizing our ASTM D1709 puncture resistance testing, they were able to identify weaknesses in their existing film material.
After conducting a series of tests, we provided critical insights into the film’s puncture resistance and recommended adjustments to the material composition. As a result, the client switched to a more durable plastic film that significantly reduced packaging failures. This not only improved product protection but also increased their customers’ trust in the safety and reliability of their medical devices.
The Outcome?
- 30% reduction in product failures during transit
- Enhanced product safety and regulatory compliance
- Increased customer satisfaction and brand trust
This collaboration exemplifies how ASTM D1709 testing can improve packaging performance and customer confidence in critical sectors like healthcare.
