The Cary Company's selection of Heavy Duty IBC Poly Totes (or Intermediate Bulk Containers) are made of durable high density polyethylene (HDPE) and are virtually maintenance free. The tapered bottom design provides full discharge of the tote contents. The base is the most durable in the industry, and completely protects the valve and sump area. These stackable units provide fork lift access to easily transfer these containers to different locations.
