The work aims to clarify the trend and extent of time-processing effects on the key properties of BOPP packaging films. Different types of BOPP packaging films were stored in a standard environment, and their key properties such as friction, heat sealing, thermal shrinkage and optical and mechanical properties were measured every other month. After the production of BOPP packaging film requires a certain aging treatment to make its physical properties reach a stable state, its time is about one month, storage time is more than 4 months, the mechanical properties and heat sealing properties of some samples may decrease significantly with the migration of additives and the aging of the film. Due to the diffusion and migration of functional additives such as lubricants, the structure and surface of BOPP are affected, leading to the effect on its key properties. Overall, on the premise that BOPP packaging film is stable for one month, the earlier it is used, the better its comprehensive performance is.
