Silo Storage
At Rainier Plastics we have the ability to store up to 300,000 pounds of product. Bulk Truck loading and unloading capabilities are not an issue with the silo storage options located on our premises.

Quality Load blending capabilities in 50,000 pound quantities
We have the blending capabilities of 50,000 pound quantities. Quality control assures that each load will have even consistency throughout to avoid variations. If you need PCR for minimum content requirements, we can source the specific grade that is most compatible with your process. Our blending capabilities allow us to homogenize the exact percentages for you, dispersing any inherent variation with the PCR so that the first bin runs the same as the last. All you need to do is place your probe, no mixing is required.

Rainier Plastics offers our customers the service of picking up your in-house scrap, reprocessing it into pellets and returning it to you in a timely fashion.
