New Software Predicts PET Bottle Shelf Life

The PETWall thickness-monitoring system from AGR TopWave LLC, Butler, Pa., is newly available with an integrated shelf-life management system.

The PETWall thickness-monitoring system from AGR TopWave LLC, Butler, Pa., is newly available with an integrated shelf-life management system. This enables blow molders to proactively manage shelf-life characteristics of PET containers as they are produced. The add-on software was developed in cooperation with Container Science Associates, Atlanta, a specialist in container performance modeling and the inventor of the M-Rule Container Performance Model. Bottle wall-thickness data captured by the PETWallplus system is analyzed by the M-Rule software and used to map material utilization in relation to shelf life for the bottles being produced. Results of the analysis are displayed on the PETWallplus monitor and are continuously updated, providing operators with an easy-to-understand visual indication of material utilization and predicted shelf life of containers. AGR TopWave says that by adjusting machine parameters that affect material distribution, processors can produce containers with optimal shelf-life and performance. PETWallplus with Shelf-life Management System allows bottle shelf-life to be predicted in real time. It reduces dependence on time-consuming off-line or laboratory testing and slashes reaction time for detecting and solving problems. The add-on software is priced under $10,000.
