The Drop Dart Impact Tester is designed to determine the impact resistance of plastic films, sheets, and packaging materials by dropping a free-falling dart from a specified height. It accurately evaluates material toughness and failure characteristics under sudden impact, making it essential for packaging manufacturers, film converters, and quality control laboratories.
With adjustable drop heights, precision-guided release mechanisms, and multiple dart weights, this tester ensures repeatable, stable, and standard-compliant results.
