With increasing focus on sustainability in packaging, Agr’s new Lightweight option for the Process Pilot® blowmolder management system gives brand owners and bottle manufactures another tool to meet this complex and growing challenge.


The Process Pilot system, with the Lightweight option provides assurance that the limited material available for producing a light weight PET bottle is distributed exactly where it needs to be, and at the appropriate thickness, to ensure proper performance.


There are many facets to this issue and improving the sustainability footprint of a product or brand can be a complex undertaking. Most avenues to sustainability are not under the direct control of the bottle manufacturer or brand owner. One option that is within their control however, is the reduction and optimization of the amount of resin that is used to manufacture the bottles. Resin (or weight) reduction per bottle does not need to be excessive to have an impact with regards to sustainability and financial benefits particularly when factoring in the quantity of bottles produced over a given period of time.


Agr’s Process Pilot blowmolder management system offers manufacturers a valuable tool to use in their weight reduction efforts. The Process Pilot system, with Agr Pilot Profiler measurement technology installed inside the blowmolder, provides a means for manufacturers to accurately measure material distribution on every bottle (to 0.05mm), in real time, and proactively adjust the blowmolder to maintain proper distribution, countering the effect of process variation.


In the push for more sustainable bottles, weights are being reduced even further and, with that, the sidewall thickness of the bottle. In order to process these bottles effectively and control the material distribution, additional measurement accuracy is required. The new Lightweight option, incorporated into the Pilot Profiler measurement component, offered with the Process Pilot system was developed to address this need for even greater measurement accuracy and control on very light bottles.


With this option, a level of control is now available with the Process Pilot system that extends the measurement range to 0.025mm, with an accuracy of +0.01mm for PET bottle sidewall material. This added functionality delivers greater distribution control on bottles with very thin sidewalls or at specific locations on other types of bottles where precise material management is critical to meet performance and quality requirements. This capability removes one of the barriers to producing usable, lighter and more sustainable bottles. For more visit
