Dart Impact Testing Services in India

What is Dart Impact Testing?

Dart impact testing evaluates the impact resistance of plastic films and laminates by dropping a hemispherical-weighted dart from a specified height onto a clamped specimen. By adjusting the dart mass and recording pass/fail outcomes across multiple specimens, you determine the impact failure threshold (often expressed as grams or energy at impact).

Why Dart Impact Strength Matters

Impact resistance is a leading indicator of durability for many flexible packaging applications. A robust dart impact value can translate into:

• Lower risk of bursting, pinholing, or tearing during distribution.
• Better protection for heavy, irregular, or sharp-edged contents.
• Optimized material usage—avoiding over-specification while meeting performance targets.
• Higher customer satisfaction and fewer returns.

Dart Impact Testing Services in India – Why Kiyo R&D Lab

Calibrated Instruments & Controlled Conditions

We operate calibrated falling-dart systems with controlled drop heights and interchangeable dart masses. Samples are conditioned to specified temperature and RH, helping ensure reproducibility across batches and time.

Standards-Aligned Methods

We align our methods to widely recognized test procedures (customer-required national or international methods) and document conditions, sample preparation, and acceptance criteria for audit-ready traceability.

Clear, Actionable Reporting

Our reports summarize the threshold mass, pass/fail statistics, observed failure modes, and interpretation against your specifications, so engineers and buyers can make fast decisions.

Consultative Support

Need to compare resins, additives, or layer structures? Our team helps you design experiments, interpret trends, and tune targets for cost-performance balance.

Our Testing Process

1. Intake & Target Definition: We review your application, performance targets, and reference standards.
2. Sample Conditioning: Films are conditioned to specified temperature and humidity for stability.
3. Fixture & Height Setup: We mount specimens in the clamp, set the drop height, and select the dart mass range.
4. Impact Trials: Sequential drops with mass adjustments per pass/fail outcomes build a distribution around the threshold.
5. Analysis: We compute the failure threshold and summarize failure modes with photos (if requested).
6. Reporting: You receive an audit-ready report with results, conditions, observations, and recommendations.

Typical Applications & Materials

• Food & Beverage: Pouches, liners, and bags that must survive filling and distribution.
• Industrial Packaging: Sacks and wraps for powders, granules, or hardware.
• Pharma & Healthcare: Sterilizable films and barrier laminates requiring reliable toughness.
• Consumer Goods: Mailers and e-commerce packaging resisting drops and corner impacts.
• Agriculture & Construction: Mulch films, vapor barriers, and protective wraps.

Reading & Using Results

Dart impact results are often expressed as the mass of the dart causing failure at a given confidence. When tracked over time, this metric becomes a powerful process control indicator:

• Quality Control: Set acceptance windows to detect drift in resin, thickness, or orientation.
• Design of Experiments: Compare resins, additives, and layer ratios to maximize robustness per gram.
• Supplier Qualification: Benchmark vendors and reduce incoming variability.
• Failure Analysis: Correlate field complaints with lab data to address root causes.
