Nylon-MXD6 is being used for PET bottle applications, both multilayer and blend, worldwide. Because of its processability, recyclability, moderate adehesion to PET layer and total cost, Nylon-MXD6 is your best choice as a barrier material in PET bottle applications for tea, juice, carbonated soft drinks or beer.
The gas barrier property of PET bottles are efficiently improved with Nylon-MXD6 content, in both a multilayer bottles or blend bottles.

Transparency of PET/N-MXD6 multilayer and blend bottle

PET/N-MXD6 multilayer bottle has good clarity as well as PET monolayer bottle. In the case of PET/N-MXD6 blend bottle, the haze increases with the N-MXD6 content.
