Kortrax BR is a barrier resin additive manufactured by BP Polymers that transforms high density polyethylene (HDPE) containers into barrier packaging thereby eliminating the fluorination process. The Association of Plastic Recyclers (APR) recognizes Kortrax BR as meeting its Critical Guidance Criteria for recyclability within the HDPE recycle stream. Kortrax BR when blended at various let down percentages creates a mono-layer barrier within the HDPE wall imparting chemical resistance equivalent to fluorination surface treatment. Baritainers made with Kortrax BR improve shelf life of active ingredients, protect against product loss of ladings, and improve survivability of the plastic package. And Kortrax BR can be utilized in containers of any shape, size, design, or color. Kortrax BR may be used repeatedly as part of a circular economy in rigid plastic container applications. It has a reduced carbon footprint since there is no additional handling and transportation of plastic packages for fluorination surface treatment post manufacturing of the container. It is also FDA, USP 661 and EU compliant.
