控制释放是二十一世纪将要开发的热门包装技术之一，其前景可观。什么是控制释放呢？就是某种产品能在特定的时间里，将一种活性成份传递到一特定的环境中去。在许多控制释放技术的应用中，活性成份是被装在能控制成份释放速率的阻隔层中的，该阻隔层中设置了引发机制以允许活 Controlled release is one of the hottest packaging technologies to be developed in the 21st century, with promising prospects. What is controlled release? It is a product that delivers an active ingredient to a specific environment at a given time. In many applications of controlled release technology, the active ingredient is contained in a barrier capable of controlling the rate of release of the ingredient in which a priming mechanism is provided to allow for viability
