Gas Barrier Technologies, include Nylon-MXD6
Nylon-MXD6 shows excellent gas barrier performance even after retorting or boiling treatment. As an example was shown in Table 2 and Fig. 5, Nylon-MXD6/PP multilayer container has much better gas barrier performance, after retorted for 30 minutes at 121 Deg. C. (250 Deg. F.)
