+ Kortrax® BR is BP Polymer’s unique and proprietary barrier resin additive for high-density polyethylene (HDPE) that utilizes laminate technology thereby creating ‘Baritainers®.

+ Kortrax® BR is based on engineered grades of Polyamide (PA) 6.

+ Customized and proprietary manufacturing processing techniques are necessary to ensure optimal barrier performance in BPI’s Baritainers®.

+ The result is a laminar microstructure in which the Kortrax® BR forms stacks of large overlapping platelets or discontinuous layers within the Baritainer® wall which limit hydrocarbon permeation.   By creating a ‘tortuous path’ for large chain molecules, hydrocarbons attempting to diffuse through the HDPE walls into the atmosphere are stopped.

+ Standard Grades:
* Kortrax® BR 70 = for containers < 5 Liters.
* Kortrax® BR 50 = for containers > 5 Liters.

+ With the same processing conditions, the amount of barrier can be adapted by the amount of Kortrax® BR added.

+ In comparison with HDPE, Kortrax® is:
* Vs. Hydrocarbons (solvents) 100 times more efficacious.
* Excellent aroma barrier.
* 2x to 5x improvement in O2 barrier performance.

+ Properties of HDPE remain unchanged:
* Printability
* Mechanical Properties
* Colorants
* UV Additive
* Seal Properties
* Anti-Static Additive
* Fire Retardant Additive
* Recyclability
