ount of moisture absorbed also depends on factors liketime, temperature, atmospheric humidity and the crystallinity of the fragment.
Packaging experts will know that presence of moisture breaks polymer chains that lead to a reduction in the molecular weight. This creates issues during preform moulding and will affect final container properties. Resins with lower molecular weight also crystallise faster than ones with higher weight resulting in hazy or white appearance. Hence, it is advised that
