    • Composition: Made from high-strength woven polypropylene or polyester, jumbo bags, also known as bulk bags or FIBC (Flexible Intermediate Bulk Container), are designed for storing and transporting larger quantities.
    • Benefits: These bags are cost-effective for transporting bulk quantities. They come with lifting loops, making them easy to handle with cranes or forklifts.
    • Usage: Ideal for industrial applications where large quantities are needed. They are also beneficial for exports due to their cost efficiency for bulk transport.

Note: Regardless of the type of packaging, it’s essential to store Gilsonite powder in a cool, dry place away from direct sunlight. Proper sealing is crucial to prevent contamination and ensure the powder’s longevity. Ensure that the storage area is free from pests and rodents, which might compromise the integrity of the packaging.



Gilsonite powder’s transportation and storage are pivotal to maintaining its quality and integrity. Here’s a tailored guide based on the packaging types:

  1. Laminated Multi-Layer Bags (25kg±5%):
    • Transportation: These bags are robust and can withstand regular handling during transportation. However, ensure that they are not subjected to sharp objects or rough surfaces that might puncture or tear the lamination. It’s advisable to palletize these bags during transportation.
    • Storage: Store these bags in a dry, cool place, preferably away from direct sunlight to maintain the bag’s integrity and protect the Gilsonite powder from moisture and UV degradation.
  2. Multi-layer Paper Bags (Kraft) (25kg±5%):
    • Transportation: Kraft paper bags are sensitive to moisture, so they should be transported in vehicles or containers that are dry and free of any leaks. It’s best to avoid transporting these bags during rainy seasons or under humid conditions.
    • Storage: These bags should be stored off the ground, preferably on pallets in a well-ventilated, dry space. It’s crucial to ensure that the storage area is free from water leaks or dampness.
  3. AD Star Bags with Weight (25kg±5%):
    • Transportation: The durability of AD Star bags allows them to withstand rougher handling. They can be stacked efficiently in transportation vehicles, but it’s still essential to ensure they aren’t pierced by sharp objects.
    • Storage: Given their robust nature, they can be stacked in storage areas. However, it’s best to store them in dry places and ensure they’re not in direct contact with the floor.
  4. Jumbo Bags (850 kg to 1 ton):
    • Transportation: Due to their size and weight, jumbo bags should be lifted with equipment like cranes or forklifts. Always check the bag’s lifting loops before transport to ensure they’re intact and can handle the weight.
    • Storage: These bags can be stored in warehouses or open storage areas but should be placed on a clean surface or pallet to avoid contamination from the ground. If stored outside, it’s advisable to cover them with a tarpaulin to protect against rain and direct sunlight.

General Tips:

  • Always check the integrity of the bags before and after transportation to ensure there’s no leakage or contamination.
  • During transportation, ensure that Gilsonite powder is kept away from any harmful chemicals or substances that might interact with it.
  • Regularly inspect storage areas for pests, rodents, or any conditions that might compromise the Gilsonite powder’s quality.
  • It’s always recommended to use the first-in, first-out (FIFO) system when using stored Gilsonite to ensure that older stock is used before the newer stock.
