Modelling capping of 28 mm beverage closures using finite element analysis

Understanding the performance of packaging on production lines is of course extremely important to the packaging industry. Computer simulation techniques have improved vastly in recent years, and modelling the complex interaction of three-dimensional threaded shapes, like closures, is now a reality. This paper outlines the work undertaken in understanding the possible mechanisms relating to the capping of 28 mm beverage closures and the use of experimental and computer simulations in order to establish that understanding.
