Plastic Resin Storage Tanks with Proven Flow Performance

Storage Requirements for Plastic Resin Producers and Processors

The supply chain integrity of plastic resin hinges on flawless storage. A single contamination event or material degradation in a standard silo can shut down a production line, resulting in expensive wasted batches and unplanned downtime. This is why dedicated resin silos are not just simple containers. Their engineered, factory-applied coatings are specifically formulated to be non-contaminating, serving as the primary defense for preserving pellet purity from receipt to final processing.

Flow performance is a core design factor. Hopper slopes typically range from 30 to 75 degrees and are matched to the resin’s flow behavior determined through testing. Selecting the right flow regime, whether funnel flow, mass flow, or expanded flow, limits risks like ratholing, segregation, or hang-ups that slow production. Safety and operations are supported by standard accessory packages that include guardrails, ladders, level indicator mounts, vents, manways, and roof access hatches.

The construction of these storage systems is based on material compatibility and long-term performance. We fabricate resin silo units from coated carbon steel, aluminum, or stainless steel, each featuring a proprietary baked-on coating formulated explicitly for plastic resin storage. Our in-house field installation crews manage the entire process, providing a turnkey design-supply-install capability. The system can be completed with auxiliary equipment such as dust collectors, slide gates, vacuum boxes, and an integrated conveying line to create a seamless bulk handling operation.
