Le pellicole di plastica utilizzate negli imballaggi, nei dispositivi medici e nell'elettronica devono sopportare varie forze durante la produzione, il trasporto e la manipolazione. Per garantirne la durata, si esegue un test d'impatto del film per valutare la resistenza del materiale agli impatti meccanici improvvisi. Questa guida illustra lo scopo del test, le procedure standard e i materiali adatti, concentrandosi su metodi ampiamente riconosciuti come il [...]

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 […]
