Why Manufacturers Trust Pacorr for Dart Impact Resistance Testing

Dart Impact Tester is a vital instrument used across industries where the durability of packaging materials cannot be compromised. It evaluates how well plastic films and sheets can withstand sudden mechanical impact, helping ensure products stay protected throughout handling and transportation. Pacorr’s advanced testing solutions are tailored to meet global quality standards, offering unmatched precision for modern manufacturing needs.

What is Dart Impact Testing and Why Is It Important?
The dart impact test evaluates a material's ability to withstand the shock of a falling hemispherical weight commonly known as a dart. This test simulates real-world conditions where plastic packaging might be dropped or struck during handling, storage, or transport. The results of this test help manufacturers determine the robustness of their materials, enabling them to fine-tune formulations or adjust manufacturing processes for better impact resistance.

Pacorr understands that a film’s integrity directly influences product protection, especially in sectors like food and beverage, medical supplies, and e-commerce. By offering reliable, high-performance dart impact testers, Pacorr helps industries minimize packaging failures and reduce customer complaints caused by ruptured or torn materials.

Key Testing Standards: ASTM D1709 and ISO 7765
Dart impact resistance is not just a best practice it’s a standardized requirement. Two of the most recognized international protocols for this test are ASTM D1709 and ISO 7765-1. These standards provide detailed methodologies to ensure consistent and repeatable results across different laboratories and industries.

Under ASTM D1709, there are two test methods:

• Method A, which uses a dart with a 38 mm diameter
• Method B, which employs a 50 mm diameter dart

In both cases, the procedure involves dropping the dart from a specified height onto a plastic film specimen clamped over a circular opening. The mass of the dart is adjusted until the test yields 50% failure meaning half the samples rupture upon impact. This statistical approach, known as the staircase method, ensures data reliability and mitigates the effects of outliers.

Pacorr’s dart impact testers are carefully designed to align with both ASTM and ISO protocols, allowing users to confidently meet regulatory benchmarks and industry demands.

What is a Dart Impact Tester and How Does It Work?

How Pacorr’s Dart Impact Testers Work
Pacorr’s dart impact testers follow a robust mechanical and electronic process for precise results. The system typically includes a pneumatically clamped sample holder, a calibrated dart release mechanism, and an adjustable drop height system. A dart of defined weight is released onto the clamped sample, and the film is visually inspected for rupture or tear.

With advanced control panels, digital interfaces, and programmable parameters, Pacorr’s machines bring both convenience and control to the testing process. Safety shields, interlocking clamps, and emergency stops ensure operator safety without compromising functionality. Whether used in a dedicated lab or on a production floor, these testers deliver the accuracy and repeatability engineers depend on.

Real-World Applications of Dart Impact Testing
Dart impact resistance data is valuable across several sectors. In flexible packaging, for example, it helps assess how a pouch will perform if dropped during distribution. In agriculture, it determines whether greenhouse films can handle wind-blown debris or physical contact from workers.

Pacorr’s customers use dart impact testers to validate the strength of materials like:

• LDPE and HDPE films
• BOPP, PET, and other multilayer laminates
• Biodegradable plastic substrates
• Shrink and stretch wraps used in logistics

For packaging developers, this test becomes an early indicator of how a new material or film formulation will behave under stress. Pacorr’s precision instruments empower these professionals to make data-driven design decisions.

Importance of Impact Resistance in Sustainable Packaging
As brands shift toward sustainable and biodegradable materials, the mechanical limitations of these alternatives become more apparent. Thinner films, reduced plastic content, and starch-based polymers often underperform when subjected to physical stress. Dart impact testing becomes essential in validating that these eco-friendly materials don’t sacrifice protection in favor of sustainability.

Pacorr stays ahead of this curve by enabling material scientists and manufacturers to compare the impact resistance of bio-based films against traditional polymers. This not only aids compliance but also builds consumer trust in the reliability of green packaging solutions.

Optimizing Material Formulation Through Testing
One of the most valuable uses of dart impact testing is in research and development. By analyzing failure data, engineers can make informed decisions about polymer selection, film thickness, and additive usage. For instance, increasing the orientation of molecular chains in the film can enhance toughness, while certain fillers may improve shock absorption.

With Pacorr’s reliable testing infrastructure, R&D teams can run iterative tests to refine packaging materials before scaling up production. This proactive approach minimizes waste, reduces recalls, and leads to better-performing products on the market.
