Nylon-MXD6/Polypropylene Laminated Containers

Laminated sheets and containers composed of polyolefin and Nylon-MXD6 retain their gas-barrier characteristics after a retorting process. Moreover, any gas-barrier quality reduction caused by retorting will quickly recover. Table 10 shows the change in the oxygen transmission coefficient of retorted laminated containers. Fig. 9 shows the cumulative oxygen transmission coefficient of retorted laminated containers.
