A dart impact tester is an essential instrument for measuring the toughness and impact resistance of plastic films, packaging materials, and other flexible sheets. By dropping a weighted dart from a fixed height onto a sample, the tester determines how much impact energy the material can tolerate before puncturing or tearing. For manufacturers in Kenya — especially those producing packaging films, flexible wraps, or consumer-goods packaging — such testing ensures materials withstand handling, transport, and environmental stress. This leads to fewer damaged goods, lower returns, stronger customer trust, and better compliance with quality standards.
