Aggregate Bulk BagS

Bulk bags (FIBCs) are essential for safely transporting and storing all types of aggregates, from fine sands to heavy stone. At FlexSack, our custom aggregate bulk bags deliver the durability, moisture control, and handling efficiency you need to keep your projects—and your supply chain—running smoothly.  

Overview of Aggregates Commonly Transported 

Building and landscape projects rely on a variety of aggregate materials, each with its own handling challenges.  FlexSack’s FIBCs are engineered to handle them all: 

      • Sand (masonry, concrete, silica): Fine particles that demand dust-sealing spouts and moisture-resistant liners.
      • Gravel & Crushed Stone: Heavy, angular pieces requiring high tensile strength and stable stacking. 
      • Pea Stone & River Rock: Smooth, rounded granules that flow easily but still need secure containment. 
      • Recycled Concrete & Asphalt Granules: Eco-friendly materials that benefit from ventilated or liner-protected bags. 
      • Landscape Mulch & Soil Blends: Organic mixes that need breathable, ventilated packaging to prevent mold.

Why choose Bulk Bags for Aggregates 

  • High Strength & Durability: Engineered from heavy-duty woven polypropylene, rated for loads up to 3,000+ lbs in rugged conditions. 
  • Dust & Debris Control: Sealed spout closures and optional liners keep fine particles contained and work areas clean. 
  • Moisture Management: Coated fabrics and polyethylene liners protect against rain, humidity, and onsite washdown.  
  • Efficient Handling & Storage: Square-cut baffle bags stack neatly on pallets, maximizing warehouse and transport space.

Duffle Top Bags  Mulch, recycled fines, landscape soil  Wide, open top for fast loading of bulky, variable materials 
Spout Top/
Bottom Bags 		 Fine sands, silica, concrete washout  Precise fill/discharge minimizes dust, waste, and spillage 
Ventilated Bags  Mulch blends, soil mixes, organic aggregates  Airflow prevents moisture buildup, mold, and odors 
Open-Mouth Bags  Gravel, river rock, oversized stone  Unrestricted loading for large, irregular pieces.

What Our Customers Say 

“I’m cutting almost $300 a truckload out of my cost, just because [our rep] got us using the right size. The pricing has been fantastic, but that really hasn’t been the true savings for me. The true savings were being able to store a lot more product on our floors because it had gotten to the point we would have stopped production because they didn’t have anywhere to put the bags. That’s not an issue any longer.”

FAQ

Our FIBCs are rated from 1,000 lbs up to 4,000 lbs+, depending on fabric strength and design—perfect for everything from sand to heavy stone. 

  • Fine sand: Spout-top or spout-bottom bags with liners for dust control. 
  • Crushed stone: Baffle Bags for stable stacking or open-mouth bags for rapid filling. 

Yes. We offer coated fabrics and multi-layer polyethylene liners to protect moisture-sensitive aggregates like silica or mortar sand. 

Absolutely.  UV inhibitors can be added to extend bag life when left outdoors or exposed to sunlight. 

Typical lead times range from 2-4 weeks after design approval. Contact us for a precise estimate based on your specifications.
