If not taken care of, some of the problems that can occur are haziness, spaces and sliver streaks in the PET bottle. These flaws also come in the way of gaining better physical and mechanical properties. It is said that PET inits amorphous form absorbs moisture more rapidly than in its crystalline form. (The high level ofcrystallinity in PET (50%) helps in slower moisture absorption rate.) The am
