Laminar Barrier Technology:

The laminar barrier technology is a combination of a barrier product together with an appropriate production technology.
By processing under well defined conditions in adapted extrusion equipment PA is stretched in thin lamellas in a PE matrix.
In this way an integrated layered structure is originated, where a multitude of overlapping PA platelets guarantee improved permeation results.
The QUORAL BR 50/70 range is based on special grades of PA 6 & PA66.
It provide barrier properties from 10 to 200 times better than HDPE.
Through use of an adapted adhesive, optimal adhesion with PE is guaranteed.
It is a dry blend which is adapted to the container size to be produced in order to reach optimum adhesion between PA and the PE matrix
