P and G Licenses Its Bottle Simulation System

Proctor & Gamble Co., Cincinnati, has licensed its proprietary computer simulation software for plastic bottles to Stress Engineering Services Inc., a package engineering consulting firm in Mason, Ohio.

Proctor & Gamble Co., Cincinnati, has licensed its proprietary computer simulation software for plastic bottles to Stress Engineering Services Inc., a package engineering consulting firm in Mason, Ohio. P&G’s Virtual Package Simulation is based on software from Abaqus Inc., Providence, R.I., to predict bottle performance. The software simulates extrusion blow molding of HDPE and PP containers. Customized, automated finite-element analysis helps designers identify where bottles can be made lighter and stronger.


Among the key modules is the Bottle Optimal Weight System (BOWS), which optimizes material distribution for minimal weight while ensuring that the bottle meets topload specifications. The Structures module simulates how the package will perform under standard loading conditions such as filling and shipping. The Virtual Race Track module simulates how the container will perform on a standard packing line conveyor.
