food-grade plastic

Food-grade plasticizers are often used as additives in plastic food packaging to increase the plasticity or to decrease the viscosity of wrapping material. These can alter the physical properties of the packaging which results in augmented flexibility and reduced brittleness. This is achieved by decreasing the molecular attraction between the polymer chains which eases any form of processing.

To begin with, let’s define plasticity, plasticizers and food-grade plasticizers.
