ASTM D1693

What is the Approved Packaging Material for Fully Regulated Items in Travel? Reference Standard: ASTM D1693 Standard Test Method for Environmental Stress-Cracking of Ethylene Plastics Short Answer Travel lotion bottles frequently fail because deep-freeze temperatures in cargo holds cause polymer micro-crystallization, making them brittle enough to shatter during hydraulic impacts from baggage handling. Simultaneously, the low surface energy of untreated PE plastics allows the abrasive nylon fibers of travel bags to easily shear away printed ink during high-frequency vibrations. Cargo Deep-Freeze Micro-Crystallization & Hydraulic Impact Overload When evaluating the structural integrity of a 150ml PE lotion bottle during commercial air travel, engineering analysis must move beyond simplistic atmospheric pressure differentials. … 続きを読む
