The crystallization of PP (polypropylene) is the main cause of opacity. By using the crystallization tendency of PP to freeze quickly, a transparent film can be obtained. However, for products with a certain wall thickness, due to the time required for heat conduction, the core layer cannot be quickly frozen. Cooling freezes, so for products with a certain thickness, we cannot expect to use rapid cooling to improve transparency. We must start from the crystallization rules and influencing factors of PP.
