    Packing Polyphenylene Sulfide is packaged in 25 kg moisture-resistant, multi-layered kraft paper bags with inner polyethylene liners, labeled for chemical safety.
    Container Loading (20′ FCL) A 20′ FCL can typically load approximately 20–22 metric tons of Polyphenylene Sulfide, packed in 25 kg bags on pallets.
    Shipping Polyphenylene Sulfide (PPS) is typically shipped in sealed, moisture-proof bags or drums to prevent contamination and moisture absorption. Packaging must be labeled according to safety regulations. During transport, it should be kept dry and protected from physical damage. Shipping is conducted in compliance with local, national, and international chemical transport regulations.
    Storage Polyphenylene Sulfide (PPS) should be stored in a cool, dry, well-ventilated area, away from moisture, strong oxidizing agents, and direct sunlight. Keep PPS in tightly sealed containers or original packaging to prevent contamination and degradation. Maintain temperatures below 35°C and avoid exposure to high humidity, as PPS can absorb moisture, affecting processing and properties. Handle with appropriate protective equipment.
