Why Do Travel Size Toiletries Containers Get Scratched and Leak? Reference Standard: ASTM D1693 – Standard Test Method for Environmental Stress-Cracking of Ethylene Plastics & ISO 9001 quality management standards. Short Answer Travel size toiletries containers experience surface degradation and mechanical failure primarily due to micro-abrasive “sandblasting” from suitcase particulates and localized stress concentration at the neck under heavy luggage loads. Furthermore, the volumetric swelling of the PE matrix when exposed to polar surfactants triggers a cyclic “expansion-contraction” stress that compromises the structural yield strength of the vessel. 物理磨损演迹：行李箱微观碎屑对 PE 容器光学透明度的“喷砂效应”分析 (Physicochemical Abrasion: Sandblasting Effects of Suitcase Micro-particulates on PE Translucency) In the dynamic environment of a transcontinental flight, travel … 続きを読む
