Since the introduction of PET bottles, light weighting has been an important tactic in reducing costs. As producers continue to reduce the material content in PET bottles, they are closing in on the light weighting limits. Producers are realising that the closer you get to the limits, it becomes all the more difficult to process these bottles. Minor changes in the process can have major effects on the material distribution and the performance of an ultra-light bottle. The more material that is removed, the smaller the overall processing window becomes. At this point, tight control over the process is imperative. Therefore the need to control the location and the thickness of the remaining material is critical. Agr’s Process Pilot® blowmolder management system offers manufacturers a means to take the variability out of light weighting and provides the additional process feedback that makes it possible to take light weighting to the limits with full confidence.
