Nylon-MXD6/PET Laminated Bottles and Nylon-MXD6/PET Blended Bottles

Table 11 shows the properties of Nylon-MXD6/PET laminated bottles, as compared with the properties of PET bottles. Table 12 shows the properties of Nylon-MXD6/PET blended bottles.

Fig. 10 shows the change in the concentration of Vitamin C (L-ascorbic acid) packed in Nylon-MXD6/PET laminated bottles. Fig. 11 shows the retention of carbon dioxide when Nylon-MXD6/PET laminated and single-layer bottles are filled with a carbonated drink.
