For packaging fields such as food and medicine with high moisture sensitivity, in order to prolong the shelf life of commodities, higher requirements are put forward for the barrier properties of packaging materials. Polyvinylidene chloride (PVDC) has strong barrier properties to water and oxygen. The existing packaging material often takes BOPP base film as the carrier and PVDC as the surface coating material to form a PVDC coated film on the base film.
