How Do Surfactants Degrade Plastic Packaging? The Physics of ESCR Reference Standard: ASTM D1693 (Standard Test Method for Environmental Stress-Cracking of Ethylene Plastics). Short Answer Polyethylene (PE) packaging fails in aggressive environments due to macromolecular chain scission caused by surfactants. By utilizing Superior ESCR resins, optimizing PCR blending rheology, and applying in-line flame treatment to activate surface free energy, manufacturers can effectively prevent stress-cracking while maintaining structural memory and print adhesion. Macromolecular Chain Scission: The Physics of ESCR in Surfactant Environments When addressing the structural failure of PE and PP cosmetic packaging, the root cause extends far beyond mere physical impact. The true vulnerability lies in a phenomenon known as … 続きを読む
