    Packing & Storage
    Packing Propylene Glycol is packaged in a 200-liter blue HDPE drum with secure screw cap, labeled with hazard and product information.
    Container Loading (20′ FCL) Propylene Glycol is loaded in 215kg steel drums, 80 drums (17.2 MT) per 20′ FCL, securely packed for transit.
    Shipping **Propylene Glycol** is typically shipped in tightly sealed drums, totes, or bulk tankers, protected from moisture and contaminants. It is classified as non-hazardous, but containers must be labeled appropriately. Store and transport in cool, well-ventilated areas, away from strong oxidizers, in compliance with local and international regulations.
    Storage Propylene Glycol should be stored in tightly closed containers made of stainless steel, aluminum, or approved polyethylene. Keep it in a cool, dry, well-ventilated area away from direct sunlight, heat sources, and incompatibles such as strong oxidizers. Storage temperatures should ideally be between 10°C and 32°C (50°F–90°F). Avoid moisture contamination and ensure proper labeling and secondary containment to prevent spills.
    Shelf Life Propylene Glycol typically has a shelf life of 2 years when stored in tightly sealed containers, away from heat and direct sunlight.
