Пластмасовите фолиа, използвани в опаковките, медицинските изделия и електрониката, трябва да издържат на различни въздействия по време на производството, транспортирането и обработката. За да се гарантира тяхната издръжливост, се извършва изпитване за удар на фолиото, за да се оцени устойчивостта на материала на внезапни механични въздействия. Това ръководство описва целта на изпитването, стандартните процедури и подходящите материали, като се фокусира върху широко признати методи, като например [...]

The Falling Dart Impact Test is a key procedure used to assess the strength and durability of films, particularly in industries where packaging materials need to withstand sudden impacts. The test simulates real-world conditions where packaging materials may be exposed to physical stresses. What is the Dart Impact Test? The Falling Dart Impact Test is […]
Dart Impact Testing of Polyethylene Film per ASTM D1709 Introduction to Dart Impact Testing of Polyethylene Film Polyethylene films are widely used in packaging due to their durability, flexibility, and lightweight characteristics. However, to ensure performance during shipping and handling, understanding their mechanical behavior—particularly under sudden impact—is essential. Dart impact testing of polyethylene film offers a reliable […]
Understanding a material’s ability to withstand sudden shock or puncture is essential for ensuring durability in real-world applications. The film pendulum impact tester plays a vital role in quantifying this characteristic, especially for plastic films, laminates, and flexible packaging materials. By following standardized methods such as ASTM D3420, this testing approach provides valuable insights into […]
