Customer Portal

Conitex-Sonoco provides top-quality bulk bag solutions for a wide range of products including those in the Aggregate & Construction industry. We recognize that custom solutions are needed in order to package and transport sand, gravel, and more which is why our products are made-to-order for your business needs. 

We understand that many companies may store their products outside, requiring a packaging solution that can withstand the elements. Our Material Science Engineers make bag customizations based on your company’s types of production, handling equipment and shipping operations. For instance, if UV protection is a concern of yours then we can add in a UV additive or recommend a black bulk bag for 35% increased UV performance over a standard white bulk bag.

We expertly produce a variety of bags with care and ensure they can handle heavy loads. The materials are reinforced for construction products of up to 8,000 lbs with a 6:1 safe working load. One of our reinforcement methods include sift proofing to address product loss in finer grades of aggregate materials such as sand. In addition to FIBC bulk bags, we also offer polypropylene valve bags and paper bags to ensure you have a variety to choose from in order to better fit your needs.
